Polka Dot Cake Recipe
Active time: 20 minutes
Total time: 2 hours
Preheat oven to 350°. Spray an 8” springform pan with cooking spray and line bottom with waxed or parchment paper. Set aside.
Following instructions on box, combine cake mix, eggs, buttermilk and oil in a large bowl. Beat with an electric mixer on low speed until moistened, about 30 seconds. Increase mixer speed to medium-high and beat, scraping down sides, until thick, about 2 minutes longer (you should have about 5 cups batter).
Spoon 1/3 of batter into bottom of prepared pan and smooth. Press 7 of the plain doughnut holes into batter. Spoon half of the remaining batter over doughnut holes to cover and smooth. Press 5 more plain doughnut holes into batter (reserve remaining 3 plain doughnut holes for decoration). Spoon remaining batter on top, making sure doughnut holes are completely covered, and smooth.
Bake until cake is firm and a toothpick inserted in center comes out clean, 45 to 50 minutes. Transfer cake to a wire rack and cool 10 minutes. Invert, remove pan and cool completely.
Cut all remaining doughnut holes in half to make 24 semicircles.
Transfer cooled cake to a serving platter. Spread chocolate frosting on sides and top of cake and make soft swirls with an offset spatula or the back of a spoon. Press halved doughnut holes, cut side down, into frosting in an evenly spaced pattern over top and sides of cake.
