This delightful Marbled Pound Cake with chocolate icing features moist and tender chocolate and vanilla cake swirled together into a beautiful and yummy loaf.
Preheat the oven to 350℉. Grease a 9x5-inch loaf pan with butter or non-stick spray.
In a bowl using an electric mixer, cream together the softened butter and white sugar for 1 minute. Add the room-temperature eggs and vanilla and continue creaming at high speed until fluffy. Add the sour cream and mix just until incorporated.
½ cup salted butter, ¾ cup granulated white sugar, 2 eggs, 1 teaspoon vanilla extract, ½ cup sour cream
In a separate bowl, whisk together the flour and baking powder before adding to the combined wet ingredients and mixing at low speed just until no streaks of flour remain.
1 cup all-purpose flour, 1 teaspoon baking powder
Melt ¼ cup of chocolate chips in a heat-safe bowl in 15-second increments, stirring between each increment until smooth and completely melted. Fold half of the batter into the melted chocolate along with the cocoa powder just until smooth.
¼ cup semisweet chocolate chips, 2 tablespoons cocoa powder
Alternate scoops of both the chocolate and vanilla into the greased loaf pan using a cookie scoop or teaspoon until all the batter is used up. Use a butter knife to gently swirl the batter around throughout the loaf to create a marbled loaf being careful not to overmix so that each batter still has definition.
Bake in the preheated oven for 45-55 minutes or until a toothpick inserted into the center comes out clean. Remove from the pan after 10 minutes and let cool while making the icing.
Melt the butter and ¼ cup of chocolate chips for the icing in 15-second increments, stirring between each increment until fully melted. Then, whisk in the powdered sugar, cocoa powder, vanilla, and enough milk to make a spreadable yet not runny icing. Spread over the cooled loaf. Let the icing set for about 15 minutes before slicing to serve for clean slices or dig right in! Enjoy!
2 tablespoons salted butter, ¼ cup semisweet chocolate chips, ½ teaspoon vanilla extract, 1 tablespoon cocoa powder, 1 tablespoon milk, ½ cup powdered sugar
Notes
It is very important that the eggs and butter be at room temperature to allow them to incorporate into the batter well for a fluffy and smooth batter.
Nothing fancy is necessary, I simply use semisweet chocolate chips for the chocolate in the batter and icing. To avoid seizing, it is important to slowly melt the chocolate in 15-second increments if using the microwave! Or melt low and slow in a pot on the stove.
Store fully-cooled pound cake covered at room temperature for up to 4 days.
