Reese's Cake

Cake preparation

• 1

  Preheat the oven to 350 degrees. 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. Then add the oil and sour cream and whisk to blend. Gradually beat in the water, then 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. (These cakes are very, very soft. It might be easier to work with after firming them up in the freezer for 30 minutes. They’ll defrost quickly once assembled.)

  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.

• 5

  Making a crumb coat of frosting (a thin layer that binds the dark crumbs to the cake so they don’t show up in the final outer frosting layer) is a great idea for this cake, or any with a dark cake and lighter-colored frosting. Once you “mask” your cake, let it chill for 15 to 30 minutes until firm, then use the remainder of the frosting to create a smooth final coating.

• 6

  Once the cake is fully frosted, it helps to chill it again and let it firm up. The cooler and more set the peanut butter frosting is, the better drip effect you’ll get from the Chocolate-Peanut Butter Glaze.

• 7

  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.

Peanut Butter Frosting Preparation

• 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, usually about 3 to 4 minutes.

• 2

  Add the peanut butter and beat until thoroughly blended.

Chocolate Peanut Butter Glaze Preparation

• 1

  In the top bowl of a double-boiler (or 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.
