Colorful Rainbow Rice Krispies Treats are so much fun! Make them for a unicorn party, St. Patrick’s Day or to celebrate spring.
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.
Return the bowl to the microwave and cook on high for 30-45 seconds. Stir until smooth. Add food coloring and stir until combined.
Then, add the rice krispies and stir until they are coated with the marshmallow mixture.
With greased hands (spray them with a little cooking spray) shape the marshmallow coated rice krispies into a long tube on a silicone mat or a greased surface.
Continue making different color layers of rice krispies treats and layering them on top of the other colors.
Firmly press all of the layers to together forming a long tube that looks like a rainbow on the end.
Cut the tube of rice krispies treats into slices revealing the adorable rainbow in each slice.
Store the rainbow rice krispies treats in an airtight container.
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
