Rainbow Cupcakes

While driving to dinner the other night, my friend Bri and I saw a double rainbow ahead of us. It was so exciting! I can't even remember the last time I saw a COMPLETE rainbow, let alone a double rainbow at the exact same time!

It was pretty crazy, and we took it to mean that good luck was definitely coming our way. Of course, after seeing that double rainbow, I wanted to share this adorable little Rainbow Cupcakes Recipe with you guys!

You can make this Rainbow Cupcakes Recipe with or without the Wilton decorating kit, it's really versatile and fun to make! If you aren't using the kit, just buy candy stripes and mini marshmallows!

Directions for how to make Rainbow Cupcakes

Preheat the oven to 375 degrees F.

Combine the softened butter, sugar, egg whites and vanilla mixing well. Slowly fold in the flour, salt and baking powder. Lastly, add
the milk continuing to stir.

Pour into greased muffin tins (or liners) and bake 20-25 minutes. Insert a toothpick around 20 minutes and if it comes out clean the
cupcakes are done.

*Makes approximately 12 cupcakes

Now onto decorating!

Add a few drops of blue food coloring to the white frosting and mix well. 

Generously frost each cupcake and set aside.

Open the Wilton Rainbow kit and carefully bend the rainbow candy one at a time and place on top of the cupcake, gently pressing down.

Next, take 2 cloud candies for each cupcake and place them next to the rainbow on either side. You might need a little bit of extra frosting
to make them stick.

*Makes 12 Cupcakes. 1 cupcake = 1 serving
