Instructions

Step 1
Preheat oven to 350°F. Lightly spray the Ninja™ Foodi™ NeverStick™ Premium 9” Round Cake Pan with nonstick cooking spray and line with 9-inch parchment round. Set cake pan over baking sheet. Set aside.

Step 2
In a large bowl, whisk to combine flour, sugar, baking powder, and salt.

Step 3
In a separate small bowl, add the egg, buttermilk, sour cream, oil, and vanilla, and whisk until fully combined.

Step 4
Add the wet mixture to the dry mixture and gently fold together until just combined and some lumps remain. Fold in the sprinkles, making sure not to overmix.

Step 5
Transfer batter to prepared pan and spread top into an even layer.

Step 6
Transfer pan to oven and bake for 25 to 30 minutes, or until cake is set and a toothpick inserted in the center comes out clean or with few crumbs.

Step 7
When cooking is complete, allow pan to cool on wire cooling rack.

Step 8
Meanwhile, prepare the frosting. In a large bowl, add all frosting ingredients except sprinkles. Using an electric mixer, beat frosting until smooth and fluffy, about 3 minutes.

When cake is cool, carefully remove from pan. Ice cake and top with additional sprinkles as desired. Slice and serve.
