Confetti Layer Cake

with about 1 cup about 250g of frosting. Repeat with second cake layer 1 more cup of frosting and then the top cake layer. Spread a thin layer of frosting on the top and around the sides as a crumb coat. Run a bench scraper around the cake to smooth out crumb coat. Chill uncovered in the refrigerator for at least 30 minutes and up to 3 hours to set the crumb coat.
Spread the remaining frosting all over the top and sides. Garnish with extra sprinkles if desired.
Serve cake immediately or if you need to store it for a few hours place it in a cake carrier at room temperature for up to 4 hours. For longer storage refrigerate covered cake for up to 1 day. Cake is best served at room temperature though so if its been refrigerated let it sit out at room temperature for 30 minutes before serving.
Cover leftover cake tightly and store it in the refrigerator for 5 days. Again I like using a cake carrier for storing and transporting.
