Confetti Celebration Cake

This is from Betty Crocker ... I am posting the recipe as it is on the website, but I didn't follow it exactly. I used Duncan Hines' butter golden recipe cake mix and frosting. I didn't use Betty Crocker sprinkles or icing either, and I didn't measure my sprinkles!! This is a very cheerful-looking cake, so it would probably go well with a child's birthday party. Prep time includes cooling time for the cakes.
