“Piecaken” (pie + cake) is a dish that was inspired by “turducken” (turkey + duck+ chicken). Several pies are all made into a cake.
 
CakeSpy‘s “Cookie Cake Pie” in 2009 was called the “turducken of desserts.” “Cherpumple” (cherry + pumpkin + apple) was popularized in 2010 and was also called the “turducken of desserts.”
 
“Now I have something to make post-piecaken” was cited on Twitter on July 31, 2010. “I don’t care what you say - if you can have a TurDucken for dinner, then I can have a PieCaken for dessert” was cited on Twitter on November 25, 2010. Piecaken became a popular Thanksgiving dessert in November 2015.

Triple Threat: The Cookie Cake Pie
Cookies, Cakes and Pies are basically the holy trinity of baked goods.
 
Separately, each is wonderful in its own way. Cookies and milk after school. Birthday cake. Pie at Thanksgiving.
 
But what if—just what if—all of this awesome could be combined into one singular sensation?

I don’t care what you say - if you can have a TurDucken for dinner, then I can have a PieCaken for dessert.

RELEASE THE PIEKAKEN!
We had our annual holiday dinner with the Ks in mid-December. Last year, we had a Flaming Feast—everything, from cocktails to salads to dessert—was flambéed.
 
This year, inspired by the egregious but amazing cherpumple, our theme was Food Inside of Other Food.
 
The idea was that you stuff one food item with another complete food item—not with a filling or a sauce, but with another made food.

Release the Piecaken!

A friend sent me this picture (I did not make this or take the photo), and I thought it was too crazy not to be shared.  Amazing the strong reactions on both sides that this over-the-top dessert stirred up!  This, my friends, is PIECAKEN.  The sugary version of turducken.  Pie baked into a cake.  Amazing to some.  Horrifying to others.  But regardless of your position of it, piecaken did create quite the stir.

DERBYLICIOUS PIECAKEN! [FOOD & DINING]
POSTED ON: 3 MAY 2012 - 11:03AM
BY ELIZABETH MYERS
There are times to eat healthy, and then there’s Derby, a time for all the mint juleps and bourbon balls and whiskey you can stuff into your face. In the land of the deep fried, the chocolate dipped, the bacon infused, I decided to make the most ridiculous Derby dessert ever: a piecaken. A piecaken is a pie baked inside a cake, frosted like a regular cake but then when you cut into it—VOILA! Sweet, luscious, moist pie inside a soft cake covered in frosting. The idea for a Derby Piecaken came partially from my favorite blog, and partially from a desire to cram as much chocolate and bourbon into one space as humanly possible. Where there’s a will, there’s a way.

PecanPIECaken - A Pecan Pie Inside a Maple Dark Chocolate Truffle Cake
I have been wanting to pair up my home-roasted pecans with a flourless chocolate cake for as long as I can remember, but have never got ‘round to it for some reason. And then I thought, why not put a pecan pie inside of a flourless dark chocolate cake? This seemed to be the inspiration I needed, because I jumped right to the task without hesitation

It’s official: piecaken is Thanksgiving’s reigning dessert.
 
On a recent segment of LIVE with Kelly and Michael, the chipper morning duo implied the piecaken is a new dessert discovery. In reality, though, this quirky Thanksgiving dessert dates as far back as 2010.

The mastermind behind the Kelly and Michael piecaken is Zac Young, the executive pastry chef at David Burke fabrick in New York City. In an interview with the Daily Dot over e-mail, Young explained how he brought the dessert to David Burke fabrick with the original idea to serve piecaken by the slice as a Thanksgiving special.

This year, you can have your cake — and your pie — and eat it too. That is, if a “piecaken” graces your Thanksgiving dessert spread.

Long-time foodies will recall that early versions of piecakens have been around since 2007, but this is the year that they’ve really taken off. So take your pick of our favorites, or DIY up your own combo!

Forget Turducken. It’s Piecaken Time.
By KATIE ROGERSNOV. 25, 2015

Piecaken has existed in underground dessert-eating circles for years, but a Thanksgiving-inspired recipe from pastry chefs at David Burke Fabrick in New York spent some time this week on the daytime talk show circuit. It’s a spiced poundcake with layers of pecan pie and pumpkin pie, topped with upside-down apple pie, slathered in cinnamon buttercream and edged in oat struessel. Just look at this thing.
 
Zac Young, the executive pastry chef for David Burke Group, said Wednesday that he dreamed up the recipe four months ago with Fabrick’s pastry chef, Gian Martinez. They wanted to take “dessert turducken” to the next level. The business has been churning out about 100 piecakens a day, at $49 each.
