2 cups flour
2 ½ cups sugar
¾ cup cocoa powder
2 tsp baking soda
1 tsp salt
1 cup vegetable or canola oil
1 cup sour cream
1 ½ cups water
2 Tbsp white vinegar
1 tsp vanilla extract
2 eggs
Preheat oven to 350°. Butter bottoms and
sides of three 8-inch round cake pans. Line the bottom of each pan with round
parchment paper.
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.
Bake for 30 to 35 minutes, or until a
cake tester inserted in the center comes out almost clean. Let cool in pans for
about 20 minutes. Invert onto wire racks, carefully peel off the paper liners,
and let cool completely. (These cakes are very soft, it’s easier to work with
after firming them up in the freezer for 30 minutes.)
Peanut Butter Frosting
10 oz cream cheese, room temp
1 stick butter, softened
5 cups powdered sugar
2/3 cup smooth peanut butter
In 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. Add the peanut butter and beat until
thoroughly blended.
Layer the cakes, frosting between each
layer. Frost entire cake. Let the cake chill for 15 minutes so the glaze will
set up and drip better on the cake.
Chocolate Peanut Butter Glaze
8 oz semisweet chocolate (I use good chocolate chips)
3 Tbsp smooth peanut butter
2 Tbsp corn syrup or honey
½ cup half and half
In microwaveable bowl, combine
chocolate, peanut butter, and corn syrup. Microwave in 1 minute increments,
stirring each time, until melted. Beat in half and half until smooth.
Pour onto frosted cake and smooth the
top, pushing the glaze to the edges so it runs down the sides in long drips.
*This is my very favorite cake. It often
makes an appearance for Melvin’s birthday. (Yes, he usually gets my favorite
cake for his birthday!) Swapping the peanut butter for Nutella in the frosting
and glaze also makes an amazing cake. If I don’t have cream on hand, I use a
chocolate ganache of 4 Tbsp butter, ½ cup
milk, 8 oz semisweet chocolate chips. Heat the milk and butter, pour over
chocolate, stir until melted and combined.
