Preheat oven to 350 degrees.

Prepare cake mixes according to the package directions.

Bake cake mixes in greased 8 or 9 in round cake pans according to package directions, until a toothpick comes out clean.

Allow to cool for several minutes in the pan before carefully removing and allowing to cool completely on a cooling rack.

Cut rounded tops of each cake layer off to make each layer flat.

Cut a circle out of two of the cake layers, about 4 inches, using a cookie cutter, or large cup and remove and set aside.

Layer 1 full cake layer, frost the top, followed by the 2 middle layers, with holes, frosting after each layer.

Fill the middle cavity with mixed candies.

Put top cake layer on the cake and frost the cake completely.

Decorate with remaining Pillsbury™ Funfetti® Halloween Sprinkles.

Enjoy.
