Who don't LOVE Chocolate and Peanut butter! This cake is amazing .. Originally from

This cake is INTENSE. Serve it in the thinnest slices possible, and keep a glass of milk handy.
Makes an 8-inch triple-layer cake; serves 12 to 16 (the book says, I say a heck of a lot more)
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 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. (Deb note: These cakes are
very, very soft. I found them a lot easier to work with after firming
them up in the freezer for 30 minutes. They’ll defrost quickly once
assembled. You’ll be glad you did this, trust me.)
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. (Deb note 1: 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. Deb note 2: 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.)
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.
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.
2. Remove from the heat and whisk in the half-and-half, beating until smooth. Use while still warm.
