Chocolate Peanut Butter Cake

This is the cake I made for Mother's Day this year. It was so beautiful and so rich! We served 12 people and still had leftovers. This recipe is from the Sky High Cookbook - Alisa Huntsman and Peter Wynne.

Sour Cream-Chocolate Cake

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

1/2 cup coarsely chopped peanut brittle (I skipped this)

1. Preheat the oven to 350 degrees F. Butter the bottoms and sides of three 8-inch round cake pans. (*I'm a little afraid of super high cakes, so I used 3 9 inch pans) 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 (I skipped sifting and whisked the ingredients in the 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 (9 inch pans baked for about 25 mins). Let cool in the pans for about 20 minutes. Invert onto wire racks, carefully peel off the paper liners, and let cool completely. (*After they cooled I plastic-wrapped and froze them to make it easier to decorate the next day.)

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. (*I iced the entire cake with a very thin coat then refrigerated for about 30 minutes then applied the remaining frosting.)

5. To decorate with the Chocolate–Peanut Butter Glaze, put the cake plate on a large baking sheet to catch any drips. Simply pour the 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. Decorate the top with chopped peanut brittle (*it looked so pretty already I skipped this step).

Peanut Butter Frosting
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 semisweet chocolate, coarsely chopped
3 tablespoons smooth peanut butter
2 tablespoons light corn syrup
1/2 cup half-and-half

1. In the top of a 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. (*I had lots of trouble getting the chocolate smooth at this stage. I just melted it and then added the half and half to the double boiler and whisked my hand off. It seemed like it would never come together to form a smooth glaze, but it did!)

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