Chocolate Cappuccino Marble Cake

My husband loves dessert. He likes chocolate and coffee. I like both chocolate and vanilla with a touch of coffee. This cake is a good combination for us.

1/2 cup (1 stick) unsalted butter, room temperature
1 3/4 cups cake flour
2 tsp baking powder
3/4 cup sugar
1/2 tsp salt
3 eggs
2/3 cup sour cream

1/3 cup cocoa powder
1 1/2 tsp instant cappuccino or any coffee of your choice
1/4 cup boiling hot water

Preheat oven to 350°F. Lightly grease 2 8" x 4" bread pans.

In a bowl, mix together flour, salt, baking powder and set aside.

Beat butter and sugar until light and fluffy, add vanilla, mix well and add eggs one at a time, scraping down the side of the bowl when needed. Beat until well combined. Add flour mixture in three batches alternating with sour cream, beginning and ending with the flour mixture. Do not over mix or your cake will become tough.

In a medium bowl mix together cocoa power, instant cappuccino and boiling water. Pour in 1/2 of the cake batter and mix well.

Spoon the batter into the pans, alternating the vanilla and chocolate coffee batter. Run a knife ( I use a chop stick) through the batters in a swirling motion to create the marbling effect.

Bake in the oven for 30 minutes or until the wooden pick inserted in the center comes out clean. Cool completely on a wire rack. Serve once it is cooled.
