Rice Krispy Treat Cake | Sprinkles for Breakfast

The weather is finally starting to warm up - and just in time for the first day of Spring (which is on Sunday). To celebrate, I turned my favorite Confetti Rice Krispy Treats into a cake!

Rice Krispy Treats are not only delicious, but they also happen to be very pliable. A lot of bakers use them to make obscure objects when creating sculpted cakes. But for today, I just decided to go ahead and make the entire cake out of Rice Krispy Treats.

This cake is totally customizable, but with Spring starting this weekend, and Easter around the corner, I decided to use pastel frosting and Sweetapolita's Easter Parade Sprinkle Medley.
