My husband LOVES anything that uses a “Funfetti” cake mix and I knew as soon as I saw these that they would quickly become his favorite . . . I was totally right. This is kind of a like a dense cake, which makes it easy to cut up and serve as bars. They are super easy to throw together and taste amazing.
1/4 cup rainbow sprinkles (if you use a yellow cake mix, add these in)
1/2 cup white chocolate chips
Sprinkles for the top
1/4 cup butter, softened
2-3 tablespoons milk
1 teaspoon vanilla
2 cups powdered sugar (more or less depending on how thick/runny you like it)
3-4 drops red food coloring to get desired pink color (optional)
Preheat oven to 350 degrees. Spray pan (either 8x11" or 9x9" pan) with non-stick cooking spray.
Combine the cake mix, oil, and egg in a large bowl. Add the milk to the bowl slowly ? you want the batter to remain as dense as possible. Fold in the rainbow sprinkles and white chocolate chips.
Dump batter in pan and spread to the edges. Bake for 25-30 minutes (they will be a little soft/gooey in the middle- just let them sit for about 20-30 minutes and they will set up).
To make frosting, combine all frosting ingredients together in a bowl and frost bars when cool (frosting is optional because these taste amazing without frosting, but I am a serious frosting lover, so I added some and loved the way it turned out).
