There are many ways to make King Cakes and most of them involve making a yeast bread base which has to rise several times. I make it easy by using a cinnamon cake mix.
(Easy) King Cake Cupcakes
1 cinnamon cake mix
Plastic baby or similar trinkets (make sure they are food-safe)
Buttercream or cream cheese icing
Purple, green & gold sprinkles
Make cupcakes with cake mix according to directions. Place a baby (or other figurine) in each cupcake or on top of the cupcakes. If you are having a party, you will want to have just one hidden figurine.
Frost the cupcakes & add the colored sprinkles. Serve on a platter with Mardi Gras beads or confetti sprinkled around.
