Chocolate Peanut Butter Cake

Hello, lover. Chocolate. Peanut Butter. Cake. Are there any more beautiful words in the English language? Sigh...
Oof, sorry, I was in a reverie. A peanut butter cream cheese frosting induced reverie. I know, weird, right? Peanut butter and cream cheese, and it is SO good. I ate the leftovers on graham crackers once the cake was thoroughly frosted.

I've been eyeing this recipe for months, but I didn't have any occasion to make it, until Michelle at work announced she's having a baby, and she didn't mean getting another puppy.

This was the finale of the baby shower Hugh and I hosted last week, and I think it was quite well received... though we did manage to save a piece for Jack (the husband/baby daddy).

If you like peanut butter cups and rich desserts, give it a try. Oh! Or try it as cupcakes... I bet they would be easier to frost. You could skip the glaze, too... hm. I'm giving myself ideas.

Sour Cream-Chocolate Cake with Peanut Butter Frosting and Chocolate-Peanut Butter Glaze
adapted from Sky High, Irresistible Triple Layer Cakes, via Smitten Kitchen

Makes an 8-inch triple-layer cake; serves 16 or more

2 cups all-purpose flour
2 1/2 cups sugar
3/4 cup unsweetened cocoa powder
2 teaspoons baking soda
1 teaspoon salt
1 cup neutral vegetable oil, such as canola
1 cup sour cream
1 1/2 cups water
2 tablespoons distilled white vinegar
1 teaspoon vanilla extract
2 eggs

1. Preheat the oven to 350 degrees F. Butter the bottoms and sides of three 8-inch round cakepans. Line the bottom of each pan with a round of parchment or waxed paper and butter the paper.

2. Sift the flour, sugar, cocoa powder, baking soda, and salt into a large bowl. Whisk to combine them well. Add the oil and sour cream and whisk to blend. Gradually beat in the water. Blend in the vinegar and vanilla. Whisk in the eggs and beat until well blended. Scrape down the sides of the bowl and be sure the batter is well mixed. Divide among the 3 prepared cake pans.

3. Bake for 30 to 35 minutes, or until a cake tester or wooden toothpick inserted in the center comes out almost clean. Let cool in the pans for about 20 minutes. Invert onto wire racks, carefully peel off the paper liners, and let cool completely. I took Deb's advice here and froze the layers on paper plates, thank goodness, because this is a very very soft cake.

4. To frost the cake, place one layer, flat side up, on a cake stand or large serving plate. Spread 2/3 cup cup of the Peanut Butter Frosting evenly over the top. Repeat with the next layer. Place the last layer on top and frost the top and sides of the cake with the remaining frosting. Chill the frosted cake thoroughly.

5. To decorate with the Chocolate–Peanut Butter Glaze, simply pour the warm glaze over the top of the cake, and using an offset spatula, spread it evenly over the top just to the edges so that it runs down the sides of the cake in long drips. Refrigerate, uncovered, for at least 30 minutes to allow the glaze and frosting to set completely. Remove about 1 hour before serving.

Peanut Butter Frosting aka the frosting that killed my hand mixer
Makes about 5 cups

10 ounces cream cheese, at room temperature
1 stick (4 ounces) unsalted butter, at room temperature
5 cups confectioners’ sugar, sifted
2/3 cup smooth peanut butter, preferably a commercial brand (because oil doesn’t separate out)

1. In a large bowl with an electric mixer, beat the cream cheese and butter until light and fluffy. Gradually add the confectioners’ sugar 1 cup at a time, mixing thoroughly after each addition and scraping down the sides of the bowl often. Continue to beat on medium speed until light and fluffy, 3 to 4 minutes.

2. Add the peanut butter and beat until thoroughly blended.

Chocolate-Peanut Butter Glaze
Makes about 1 1/2 cups

8 ounces seimsweet chocolate, coarsely chopped
3 tablespoons smooth peanut butter
2 tablespoons light corn syrup
1/2 cup half-and-half

1. In the top of d double boiler or in a bowl set over simmering water, combine the chocolate, peanut butter, and corn syrup. Cook, whisking often, until the chocolate is melted and the mixture is smooth.

2. Remove from the heat and whisk in the half-and-half, beating until smooth. Use while still warm.


  1. Oh my god, I am making this today for a potluck at work! Sorry to be so excitable, but I'm just enjoying the fun coincidence that the cake I have sitting in the other room that I decided to make based on how I've been slavering over it on ONE food blog is HERE, NOW, on one of my OTHER food blogs! It's so crazy!

    You aren't kidding about the icing. That stuff is hard core. Also, based on what I know was in the two tablespoons I probably ate off the mixer, I should probably spend the rest of my time before work on the treadmill. As the illustrious Inspector Gadget would say, wowsers!

  2. Wowsers, indeed! I love coincidences like that. Thanks for sharing, Melissa :)

  3. This cake makes my heart beat funny. Not in a bad way, mind you.

  4. Hi Adrienne, this is Kristen's sister Kari. I have made this a few times before and friends went completely crazy over it. I am making it again tonight for a family dinner so I had to come find the recipe again on here! Thanks for such a yummy cake!!!
