Danube Wave Cake

Step 1

Preheat oven to 350°F. Grease a 9x13-inch baking pan. In a large bowl, cream 1/2 cup butter and 3/4 cup sugar until light and fluffy, about 3 minutes.

Step 2

Beat in 2 eggs one at a time. In a separate bowl, whisk 1.5 cups flour and 1.5 tsp baking powder. Add flour mixture to butter mixture alternately with 1/2 cup milk, starting and ending with flour, until just combined.

Step 3

Spread half the batter in the pan. Stir 2 tbsp cocoa powder into the remaining batter, then spoon chocolate batter over the vanilla batter and swirl with a knife for a marbled effect.

Step 4

Scatter 1 cup cranberries evenly over the batter. Bake until a toothpick inserted in the center comes out clean, about 30-35 minutes. Let cool completely in the pan.

Step 5

For the topping, beat 1/2 cup softened butter with 1 cup powdered sugar and 2 tbsp milk until smooth and creamy, about 2 minutes. Spread over the cooled cake.

Step 6

Dust with additional powdered sugar before serving. Cut into squares and enjoy.
