Dark Chocolate Cake with Chile-Chocolate Buttercream

I have this friend. She’s a wise and confident woman with many an opinion. Her view, articulated through crystal clear lenses, is always witty and makes me laugh (and think!). More than once she has managed to fit a crutch under me and uphold me as only a true girlfriend would do. I appreciate and love her more than words can say.

So how could I not fulfill her request when she sent me a link last spring, to a cake she suggested I make? For her. Oh, did I forget to mention she can also be quite audacious?!  ;-)

Angela’s birthday seemed the perfect time to make this cake for her. So last summer I brought it to a little celebration in her honor, where a small group of girlfriends gathered on the patio to enjoy a beautiful Minnesota summer’s evening. Girlfriends, summer, tasty nibbles, wine, and a gorgeous layered cake…what more can a girl ask for?!

The original cake recipe comes from Food & Wine magazine, and featured a cinnamon sponge cake. I thought the cake was good, but not exactly memorable. The frosting, on the other hand, was pure heaven. I have dreamt of that magnificent buttercream slathered over a deep dark chocolate cake ever since. So that’s what I did!

This Dark Chocolate Cake with Chile-Chocolate Buttercream is a layer cake to remember, for sure. At its core are two layers of that deliciously famous “Beatty’s Chocolate Cake”, found in Ina Garten’s Barefoot Contessa at Home. The cake is deep, dark, and super moist, and topped with some of the most wonderful buttercream I’ve ever set my fork to. The frosting’s silky sweetness is complex, offset by the warmth of chiles and cinnamon. I love it!

Although this cake would be spectacular served any time of year, I think it would a great addition to an upcoming Cinco de Mayo party. Let me know if you celebrate with it!

Ingredients

for the dark chocolate cake:

  • 1.75 c. all-purpose flour plus more for flouring the pans
  • 2 c. sugar
  • ¾ c. cocoa powder
  • 2 tsp. baking soda
  • 1 tsp. baking powder
  • 1 tsp. kosher salt
  • 1 c. buttermilk
  • ½ c. vegetable oil
  • 2 extra-large eggs at room temperature
  • 2 tsp. pure vanilla extract
  • 1 c. freshly brewed hot coffee

for the chile-chocolate buttercream:

  • 2.5 c. 5 sticks unsalted butter, at room temperature
  • 1 lb. powdered sugar sifted
  • ¼ c. heavy cream
  • 1 tsp. pure vanilla extract
  • 1 tsp. cinnamon plus more for dusting the finished cake
  • 1 tsp. ancho chile powder
  • ½ teaspoon cayenne pepper
  • 5 oz. bittersweet chocolate melted and cooled
  • 5 oz. white chocolate melted and cooled

Instructions

for the cake:

  • Preheat oven to 350° F. Butter two 9” round cake pans. Line with parchment paper, then butter and flour the pans.
  • Sift the flour, sugar, cocoa, baking soda, baking powder, and salt into the bowl of an electric mixer fitted with a paddle attachment and mix on low speed until combined. In another bowl, combine the buttermilk, oil, eggs, and vanilla. With the mixer on low speed, slowly add the wet ingredients to the dry. With mixer still on low, slowly and carefully add the coffee and stir just to combine, scraping the bottom of the bowl with a rubber spatula.
  • Pour the batter into the prepared pans and bake for about 35 minutes, or until a toothpick comes out clean. Cool in the pans for 30 minutes, then turn them out onto a cooling rack to cool completely.

for the chile-chocolate buttercream:

  • In a stand mixer fitted with a paddle, beat the butter until creamy. At low speed, beat in the powdered sugar. Increase the speed to high and beat until fluffy, scraping down the side of the bowl, about 2 minutes longer. At low speed, beat in the cream, vanilla, cinnamon, ancho chile powder and cayenne, then gradually beat in the cooled bittersweet and white chocolate.
  • Scrape down the side of the bowl and the paddle, increase the speed to medium-high and beat until light, 3 minutes longer. Using a wooden spoon, vigorously beat the buttercream for 30 seconds to deflate any air bubbles.

to assemble the cake:

  • Place one cake layer, flat side up, on a plate or cake pedestal. With a knife or offset spatula, spread the top with almost 2 cups of the frosting. Place the second layer on top, rounded side up, and spread the remaining frosting onto the top and sides of the cake. (There is plenty of frosting and I’ve never used all of it.)
  • Lightly dust the top of the cake with additional cinnamon. So pretty!
  • Refrigerate the cake for at least 30 minutes before slicing. If the cake has been fully refrigerated (many hours or overnight) prior to serving, be sure to bring it to room temperature before serving, which can take 30 minutes or more.
  • This cake can easily be made the day prior to serving it and any leftover cake keeps well when covered and refrigerated.

  1. Hello! I am here just to tell you that this cake look DIVINE! I am ashamed to say that I only discovered ‘spiced up’ chocolate a little over a year ago. And it is the best! It takes the chocolate to a completely new level and makes it so much more satisfying! I will make this cake, I don’t know when because I have a very long list piling up of must make recipes, but this is definitively going on it!!

      1. I just made this cake today. I couldn’t wait any longer! I used a different chocolate cake but used your buttercream, and this is THE BEST buttercream I have ever had. I just love it, thank you!

      2. Oh YAY!! That buttercream…I just can’t help myself!! Thanks for taking the time to come back & let me know. :)

  2. I just bought a dutch oven last weekend, so that’s out, but I do want to get some silicone muffin “tins” (I have no idea what to call them since they’re silicone)!

  3. Not sure… before I can buy more kitchen stuff I need to buy an island or breakfast cart for more storage in my kitchen!

  4. My kitchen is in desperate need of an immersion blender. That’s what the giveaway gift certifical would go towards!

  5. I have a number of items on my kitchen wish list that could be fulfilled. Some of them include: a salad spinner, a micro-plane, an immersion blender…even a nice glass measuring cup like my mom has. :) Thanks for this wonderful giveaway and congratulations on 2 years! What a wonderful online space you have created!

  6. I would love to win your giveaway. :) And I can’t wait to try your recipe for chocolate cake!
    I just discovered your blog today, through Tasty Kitchen, and will be browsing some more!

  7. The chocolate cakes looks fantastic. The frosting has a beautiful old-fashioned bakery pattern, I hope I can duplicate. That said, I’ve had my eye on the BAKED cookbook at Amazon.

  8. Rachel@Time for Good Food

    Hmmm … tough call. I think I would buy some new baking gadgets! Your cake looks amazing, by the way.

  9. My mom put a link on facebook and I just had to check out your cake receipe! Sounds super yummy! I would probably get baking supplies at Target. I really enjoyed your website, very cute.Thank you for sharing and congrats on 2 years.

  10. I have been wanting to get some truffle molds. Would prefer silicone ones so I could use them for my homemade caramels
