Pictured above is one half of the cake recipe that appears below. I made the full recipe as shown below, and brought one half of it to a barbeque with friends on Thursday night. The other half I saved in the fridge for the above-mentioned work barbeque on Saturday. If you are interested in making your cake do "double duty" like this, I kept the baked cake in the fridge on Thurs/Fri, then took it out, let the frosting soften up, and frosted it right before the BBQ on Saturday afternoon. It still tasted perfect two days later.
Ingredients:
For the cake:
2 cups all-purpose flour
1 & 1/2 teaspoons baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
1/2 cup unsalted butter, softened
1 cup granulated sugar
1/2 cup packed light or dark brown sugar
3 large eggs
1 tablespoon vanilla extract
1 cup sour cream
1/2 cup chopped toasted hazelnuts
For the frosting:
1/4 cup unsalted butter, softened
1/4 cup unsweetened cocoa powder
1-3 tablespoons brewed strong coffee (use 3 if you want a stronger coffee flavor)
1/2 teaspoon vanilla extract
3 cups confectioners' sugar, sifted
1 to 2 tablespoons milk
Chopped toasted hazelnuts, for garnish
Instructions;
To make the cake:
- Preheat oven to 350°. Butter two 9-inch round cake pans. Line bottoms with parchment paper. Butter paper.
- Whisk together flour, baking powder, baking soda, and salt. Set aside.
- Using an electric mixer on medium speed, beat butter, sugar, and brown sugar until light and fluffy.
- Add eggs, one at a time, mixing well after each addition. Mix in vanilla.
- Reduce mixer speed to low. Add flour in three portions, alternating with two portions of sour cream. Mix until a few streaks of flour remain. Stir in hazelnuts.
- Divide batter evenly between prepared pans. Smooth batter evenly in pans.
- Bake 30-35 minutes, or until cakes are lightly browned and a pick inserted into the center comes out clean.
- Cool in pans on a wire rack for 15 minutes. Then, run a knife around the edges to loosen the cakes. Transfer cakes from pans to a wire rack to cool completely. Remove parchment paper.
To make the frosting:
- Using an electric mixer on medium speed, beat butter, cocoa powder, espresso, and vanilla until thoroughly combined.
- Gradually add confectioners' sugar. Mix until smooth.
- Add milk as needed to attain desired spreadable consistency.
- Place one cake layer on a cake plate. Spread half of the frosting on top of the cake.
- Place remaining cake layer on top of frosted cake layer. Spread remaining frosting on top of the second cake layer. Garnish with chopped hazelnuts.
