Patriotic Polka Dot Cake

By charlotteh371

Ingredients

• 1 box (16.25 oz) red velvet cake mix
• 1 cup buttermilk
• 3 large eggs
• 1/3 cup vegetable oil
• 16 plain doughnut holes
• 1 can (16 oz.) vanilla frosting
• 3 tbsp. each red and blue decorating sugar

Preparation

Step 1

Preheat oven to 350°. Line the bottom of an 8-in. springform pan with parchment paper and spray sides and bottom with vegetable cooking spray. Prepare the cake mix according to the package directions except replacing the water with the buttermilk.

2. (See the step-by-step below) Spread 1/3 of the red batter into the bottom of the prepared pan. Arrange 8 doughnut holes on top of the batter. Spread 1/2 of the remaining batter on top to cover the doughnuts. Add the 8 remaining doughnuts to the pan pressing them between the doughnut holes in the first layer. Top with the remaining batter, making sure to cover the doughnuts, and smooth.

3. Bake until a toothpick inserted in the center comes out clean, about 45 to 55 minutes. Transfer the cake to a wire rack and cool 10 minutes. Remove the cake from the pan and cool completely.

4. Place the cooled cake, flat side down, on a serving plate. Cover with the vanilla frosting. While the frosting is still wet, sprinkle with the colored sugars, using a 1½-in. round cookie cutter as a stencil, to make alternating red and blue polka dots all over the cake.
