Traditional rice krispies treats are always a great dessert choice but rainbow rice krispies treats are even more fun! They are basically the same treats but made in individual layers and formed into a rainbow shape.

Start by making the purple layer of rice krispies treats. Put the butter in a bowl and melt it in the microwave. Add the large marshmallows and stir to coat them with the melted butter.

Can I make the colors more intense?

Yes, you can add more food coloring to each layer but keep in mind that the rice krispies treats may start to taste like the food coloring.

How could I add flavor to these rainbow rice krispies treats?

We made the classic rice krispies treats but it would be fun to add different flavors to the colors of the rainbow! You could stir in a little extract or flavoring oil to each layer. Here are a few flavor suggestions:

pink – strawberry extract
orange – orange extract
yellow – lemon or pineapple flavoring
green – lime or green apple flavoring
blue – blueberry or blue raspberry flavoring
purple – grape flavoring
