The Great Pumpkin

“Each year, the Great Pumpkin rises out of the pumpkin patch that he thinks is the most sincere. He’s gotta pick this one. He’s got to.
I don’t see how a pumpkin patch can be more sincere than this one. You can look around and there’s not a sign of hypocrisy.
Nothing but sincerity as far as the eye can see.”

Always Be Here

Chocolate, Cherry, and Cacao Butter Cake | La Pêche Fraîche

You are loved just for being who you are, just for existing.
You don’t have to do anything to earn it.
Your shortcomings, your lack of self-esteem, physical perfection, or social and economic success—none of that matters.
No one can take this love away from you, and it will always be here.

Mocha and Vanilla Bean Cupcakes | La Pêche Fraîche

February, how did you come so quickly?
And how is it so warm? It is freaking everyone out. I don’t want to enjoy too much, given that we’re supposedly guaranteed another six weeks of winter (although we haven’t truly had any winter here in the Windy City).
Today, it’s 50 degrees and raining, and all I wanted this grey morning, what with the soft patter of rain on my windows, was the pull the covers back over my head and sleep for the entire day.

Mocha and Vanilla Bean Cupcakes | La Pêche Fraîche

I am going to keep is short here, today.
My theme of the month is humble and grateful love.

I want to share it with those who matter the most to me, but also with everyone in the orbit of my life.
We could all do with more widespread love. Share some with your partner, your neighbor, your friends and your frenemies.
Show someone that you are thankful for everything they have given you—their energy, their attention, their love and affection—and give it back in kind.
Put some effort into an unexpected act of kindness. No need to brag or tell anyone about it.
It will make you feel amazing too.

Humble. Grateful. Love.


Today’s treats are these simple mocha and vanilla bean cupcakes.
They’re cheekily festive, with their pastel pink frosting and bright sprinkles on top, but you could leave out the food coloring and come away with a very elegant black and white cupcake.

The base of the cupcakes is my go-to: one bowl, one whisk, comes together in 15 minutes and bakes in just 10. The cake is moist and fluffy, and it is the perfect base for a big swirl of frosting.

The frosting is an Italian meringue buttercream: like a cloud of light, whipped buttery goodness. Its flecked with the seeds of two full vanilla bean pods and a big pinch of salt—dreamy.

These cupcakes are simple but adaptable—swirl different flavors into the frosting to customize it, and top with whatever sprinkles or chopped bits you so desire.

cake portion lightly adapted from Sweetapolita

ingredients:
for the cupcakes:
95 grams (3/4 cup) all-purpose flour
150 grams (3/4 cup) superfine sugar
60 grams (1/2 cup) dark Dutch-process cocoa powder
1 teaspoon espresso powder
1 teaspoon baking soda
1/2 teaspoon baking powder
1/2 teaspoon salt
120 grams (1/2 cup) buttermilk, room temperature
80 grams (1/3 cup) coffee, hot
42 grams (3 tablespoons) vegetable oil
1 egg

for the frosting:
3 egg whites
150 grams (3/4 cup) sugar
45 grams (3 tablespoons) water
1/2 teaspoon kosher salt
335 grams (3 sticks, 1 1/2 cups) butter, softened
scrapings of 2 vanilla beans
few drops pink food coloring

directions:
Make the cupcakes: line 1 cupcake tin with liners and preheat oven to 350 degrees F.
Whisk flour, sugar, cocoa powder, espresso powder, baking soda, baking powder, and salt together in a bowl.
Pour in the buttermilk, coffee, and vegetable oil and whisk until half incorporated; add in the egg and whisk until the batter is all combined.
Portion out into the liners (about 1/4-1/3 cup per cupcake), and bake for 10-12 minutes, or until a tester comes out with a few moist crumbs.
Meanwhile, make the frosting: place egg whites in the bowl of a stand mixer.
Place sugar, salt, and water in a small pot.
Begin to heat the sugar mixture on high as you whip the whites on medium speed.
When the syrup reaches 245 degrees F, your egg whites should be at firm soft peaks (almost hard peaks, but not dry).
Drizzle the syrup into the meringue with the mixer running; whip on high until cooled to body temperature.
Beat in butter one or two tablespoons at a time.
Beat buttercream on high speed until thick, glossy, and fluffy, about 4 minutes, then beat in vanilla bean and pink food coloring until tint is as desired.
If buttercream is too soft, refrigerate for 20 minutes.
Decorate cupcakes as desired, and top with sprinkles!

Chocolate and Candied Kumquat Cake | La Pêche Fraîche

Happy 2016!
I’m a cool seven days late, but no worries—that means we only have 51 weeks left of this year.
That’s not me being eagerly pessimistic, people.

It’s just a f-a-c-t.

Chocolate and Candied Kumquat Cake | La Pêche Fraîche

Impossibly, it seems, I’m back at school.
Finishing up my first week of classes, actually.
From the outset—and let’s pray for the sake of my sanity and the number of delicious things I manage to make and photograph for the blog—it seems like this quarter will be less busy.

Of course, as I have probably stipulated before, this often has no correlation with how relaxed I feel.
The brain is a wondrous thing, isn’t it?!
…says the neuro major…

Chocolate and Candied Kumquat Cake | La Pêche Fraîche

Starting the year off with chocolate all but guarantees a pleasant January, which can be an altogether bleak and dreary month (it’s already abnormally slushy here in Chicago).

Today, I’m sharing a dark, moist sour cream chocolate bundt cake: it’s one bowl, it comes out of the pan looking simply magnificent and just as tender as a steamed pudding.
It stays soft and has a tight crumb, even over the course of a few days.
A few light lashings of vanilla cream glaze offset the chocolate nicely, although I could definitely see this paired with an equally chocolaty ganache.
Finally, the cake is topped with a golden crown of candied kumquat flowers, an auspicious, chewy, bitter, sweet, sour, and traditional treat for the Lunar New Year, which I have appropriated for this (Western) New Year cake.
Kumquat trees are a sign of prosperity and good luck in Chinese and Vietnamese New Year celebrations, and it couldn’t hurt to have some more of that in 2016, right?
Find more in depth (and a very detailed recipe) at the Kitchn.  I halved the recipe (I only made a couple handfuls of kumquats) and followed the instructions to a T and they were delightful.

The Ultimate Chocolate Cake| La Pêche Fraîche

It’s about this time of year,
when They roll out the thick grass carpets,
perfectly—exactingly—covering up last year’s dead brown sod,
that I long for the entropy of fields left to seed,
of forest floors covered in disordered brush.
When They plant the tulip bulbs, exactly 9 inches apart,
I miss the mess that is our garden,
or the crowded daffodils that line our block,
or the tiny blue flowers that pop up in our uncut lawn.
It’s not quite spring, back home, but the melt has happened,
the waterfalls are bursting and the creeks are coursing through the gorges.
I miss the water, and the hills, my God,
and I miss the redbuds that bloom so bright,
and the oak pollen that makes Mama sneeze.

The Ultimate Chocolate Cake| La Pêche Fraîche

…It’s been a while.
And I didn’t mean for it to be, but here we are and we shall have to make do.
I’ve been a busy little bee trying to keep up with the glories of biochem, which is going to be a recurring theme in these next six weeks, I’m sure.
I’ve had my head down, methodically crossing things off my to-do lists, only to look up and realize I have 4 more assignments to add on.  So it goes, as a second-year here at UChi.
So it goes.

My FOTA project goes live next week!
Which is exciting and stressful and surprising, since I have an eerie feeling that I only just applied yesterday (yesterday being, of course, 8 weeks ago).

I’m hosting a pop-up bakery, and all of the proceeds are going to the ASPCA.  Pretty pumped, people.

The Ultimate Chocolate Cake| La Pêche Fraîche

Another chocolate cake?
There are quite a few on this site, I know:
Modern Black Forest (mocha-mayo cake)
Coca-cola Caramel (coca-cola cake)
Mint Chocolate (vegan chocolate cake)
Mocha Nutella (mocha cake)
Goat Cheese/Strawberries (simple chocolate cake)

And now, another one.  And I’m not sorry at all.
This could be the best one yet.
The chocolate cake to end chocolate cakes.

The Ultimate Chocolate Cake| La Pêche Fraîche

I’ve taken the best parts of some of my favorite chocolate cakes and combined them into this recipe.
Extra-dark cocoa powder because chocolate, people.  It’s bloomed in boiling water to bring out the most flavor possible.
Plenty of coffee, to enhance the flavor of the cocoa.
The ease of a 1-bowl cake, with an added egg or two to keep a tight crumb and firm bite.
Buttermilk, to keep the cake damp and dark.
A tiny tiny touch more sugar than some of my other cakes, since some sweet teeth occasionally find dark chocolate cakes to not be sweet enough.

The Ultimate Chocolate Cake| La Pêche Fraîche
Here, I’ve paired this super moist, rich and chocolaty cake with a modified version of my beloved, addictive Nutella buttercream, with an extra few minutes of whipping and a touch more Nutella to make it even lighter and fluffier.
It’s like a soft, fluffy chocolate buttercream cloud, with enough salt to make itself known and lots of melted dark chocolate to ensure plenty of cocoa flavor.
No wimpy buttercreams over here.  No sir.

The salty-sweet buttercream is a fantastic foil for the dark chocolate cake, which isn’t too sweet.
Contrary to what you might think upon first glance, this isn’t too much chocolate.
The flavors are distinct enough that each bite of cake+frosting is in harmony, rather than one-note (which gets boring after the first few bites, let’s be honest).

This all boils down to the ultimate chocolate cake: of course there’s Nutella, and dark chocolate, only one dish to clean, not too much sugar, and sprinkles.  Always sprinkles.

A birthday without cake is just another dreary day.

Birthdays are for cakes.
(Note: cakes are definitely not only for birthdays, however.)

Mocha Cake with Nutella Italian Meringue Buttercream | La Pêche Fraîche

I’m slowly curating the birthday cakes of my roommates (Daly’s birthday is 3 days before mine, so it always happens before we get to school, but a half birthday, perhaps?).
Alexa will love this—it tickles me pink how much she loves her birthday posts.  She also, for the record, loves pink.

Just for reference, here’s Alexa’s cake from last year, and the one from this year.

Dunno if I can possibly link back to that caramel popcorn cake one more time, but oh well.

But this is a birthday cake (and post) for a girl who loves the color mint and Paris, soy lattes and Back to the Future, the Old Major sandwich at Z&H and puppies.
Who embodies the Duchess Kate Middleton and has the most brilliant hair and sleeps like Sleeping Beauty (yes, that deeply).

The one who inspired these whole wheat peppermint mocha brownies with her love of Starbucks.

Betsszzyyyy!

Mocha Cake with Nutella Italian Meringue Buttercream | La Pêche Fraîche

Elizabeth made it through 2 decades of life.

Obviously, we needed to celebrate with a very big, very chocolaty cake.
Thing is, her birthday was the day after we got back from winter break!  So I hadn’t prepared anything (usually I’ll bake the layers a day ahead or something along those lines, since the days can get so excitingly monotonously busy around here) the day of.
Still, I poked around in my kitchen for ~2 seconds and knew exactly what I had to make her.

A cake tailored to a few of her favorite things.
A cake just like her.

Mocha Cake with Nutella Italian Meringue Buttercream | La Pêche Fraîche

This cake is really easy, and miraculously fast.
I had it imagined, made, decorated, and photographed within 2 and a half hours.  Not too bad, especially when you consider that the photography took longer than any of the other processes.

The cake itself is a springy dark chocolate and coffee—mocha—cake.  It’s soft and feels light yet rich at the same time, with a good balance of sweet and bitter from the coffee and cocoa.
It’s a one bowl, one whisk, and one measuring cup kind of recipe, perfect when you need a cake, stat!

The frosting is a Nutella Italian meringue buttercream, so conceived because I had no confectioner’s sugar but lots and lots of bittersweet chocolate.
It’s impossibly light and buttery while still maintaining plenty of chocolate flavor, which I always find is missing in chocolate egg-based buttercreams.
First, a plain Italian meringue buttercream is whipped up, one big glossy cloud.  Then heaps of cooled chocolate get whisked in, and a fair dollop of Nutella, too.
The color change is mesmerizing: from the palest yellow to a red-brown cocoa.

The end result is seriously amazing.
It’s salty and sweet, chocolaty and a little bit nutty.
Italian meringue buttercreams are so silky—they pair perfectly with a cake that has a soft, tight crumb.

Mocha Cake with Nutella Italian Meringue Buttercream | La Pêche Fraîche

 This is a cake that’s perfect for a birthday.
It’s fun (sprinkles!), has flavors that everyone will like, and makes the right size cake for sharing with friends.

It frosts like a dream and will look impressive no matter how you decide to finish it up—just don’t forget the candles.

But seriously—don’t the adorable candles on this cake practically beg for extra sprinkles?!

Coca cola cake with caramel and vanilla bean | La Pêche Fraîche

A certain blonde with whom I live is going to be very happy to see this post be published—

that’s right, friends, this is Alexa’s birthday cake.

Remember last year?  Of course you do, I link back to that post ALL the time.  Lauren Conrad pinned it, for God’s sake.

It’s been a bit more than a year, now, that Alexa and I have been friends.  Miraculously, we are both still alive and have, for the most part, all of our limbs (Grandma, I’m kidding).

Who knew that the gals I met on the first day of O-week would be my roomies, my #1 wingwomen, my comfort blankets and tissue fetchers and popcorn sharers and best friends?

Coca cola cake with caramel and vanilla bean | La Pêche Fraîche

Spoiler: Alexa definitely didn’t.  She was fairly certain I hated her…
(She still hasn’t gotten the hint, guys. I think she’s following me.)

Anyways, it’s been quite an eventful year+ and I couldn’t be more grateful to have spent it with such good people.

I couldn’t have asked for a better house-mate, better roommate, and better friend.  Alexa is such a giver and can ALWAYS put a smile on my face or at least a blanket round my shoulders.
She knows what to say, who to hate, how to make popcorn the best, and how to be the most loyal, loving friend out there.
Ugh. So much love.

Coca cola cake with caramel and vanilla bean | La Pêche Fraîche

To celebrate her birthday, I made an over-the-top cake, obviously.

Alexa loves diet coke, as a sorority girl should.
Alexa loves chocolate and vanilla bean, like normal people do.
Alexa thinks that salted caramel is the stuff of gods (she is right).

Alexa is looking over my shoulder and drooling wishing for another cake right now—
“Please? I ate this for all three meals.”

Alexa is going to kill me for putting that up on the internetz but it’s ok friends I will survive because I am holding birthday cake oreo cupcakes hostage right now.
(Look for those here in the coming weeks!!!)

Coca cola cake with caramel and vanilla bean | La Pêche Fraîche

I knew I had to make a chocolate coca cola cake, and I wanted to incorporate a fat vanilla bean and some gold and sparkly caramel in there somewhere as well.

The end result is a rich, moist chocolate cola cake with vanilla bean buttercream swirled with heaps of salted caramel glammed up with gold luster dust and chocolate sprinkles.

It’s sparkly and gooey and sweet and salty and I think it was just about a perfect way to celebrate my BFF’s birthday.

Coca cola cake with caramel and vanilla bean | La Pêche Fraîche

Some notes on the cake:
you can make the cake portion and the caramel ahead, but make the frosting right before you are going to decorate the cake; the finished cake can be stored in a cool place at room temperature overnight.
The luster dust is optional, but a very nice glam touch to the caramel on top of the cake.
This caramel recipe is good for pouring, so if you don’t want to smudge it on the sides, just pour it over the top and let it drip down!

1 whole vanilla bean, scraped
1 teaspoon kosher salt

directions:
Make the cake: grease and flour 3 6-inch round pans and preheat the oven to 350 degrees F.
Place butter, oil, coca cola, cocoa powder, and salt in a large pot.
Heat over medium heat, whisking, until it comes to a boil.
Pour the hot mixture over the sugar and whisk to combine.
