Delicious Donauwelle Cake

Follow our step-by-step guide on how to make Delicious Donauwelle Cake.

1. Step 1

   Start by preheating your oven to 350°F (175°C). Prepare a 9x13-inch baking dish by lining it with parchment paper, ensuring easy removal later on.

2. Step 2

   In a mixing bowl, sift together the all-purpose flour and baking powder, then set it aside for later use. In a large bowl, beat together 1 cup of margarine until it's fluffy and light. Gradually add in the white sugar, vanilla extract, and the 5 egg yolks, mixing until well combined.

3. Step 3

   Next, gently fold the flour mixture into the margarine mixture until just combined, being careful not to overmix. In a separate clean bowl, beat the egg whites until they become foamy, then continue beating until stiff peaks form. This is the secret to a light and airy cake!

4. Step 4

   Now, take about a third of the beaten egg whites and fold it into the batter gently, preserving as much volume as possible. Once incorporated, add the remaining egg whites and fold until just combined.

5. Step 5

   Divide the batter in half; in one bowl, sift in the cocoa powder and stir until just mixed. Pour the vanilla batter into the prepared baking dish, followed by the chocolate batter on top. Finally, arrange the drained tart cherries over the chocolate layer, adding a burst of flavor.

6. Step 6

   Bake in your preheated oven for about 25 to 30 minutes, or until a toothpick inserted into the center comes out clean. Once baked, let the cake cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.

7. Step 7

   While the cake cools, prepare the buttercream frosting. In a mixing bowl, beat together the remaining margarine, confectioners' sugar, rum flavoring, and the 2 egg yolks until the mixture is light and fluffy. This frosting will add a deliciously creamy finish to your cake!

8. Step 8

   Once the cake is completely cool, spread the buttercream evenly over the top. For the best flavor, refrigerate the cake until you're ready to serve it. Enjoy this delightful treat with family and friends!
