Marshmallow rice krispies treats

Rice Krispies are a breakfast cereal and they are very light. Rice Krispies treats are great for snacking on and they are quick and simple since they do not need to be baked. I have used rice krispies treats to mould an ice cream cone to go on top of my cake below. Rice Krispies treats can also be used to make some models that go on top of cakes because they can be easier to mould and sculpt unlike fondant.

In this recipe I will share with you a recipe to make the marshmallow rice krispies treats in an 8 inch square cake tin.


  • 2 tablespoons unsalted butter
  • 3 cups mini marshmallows
  • 3 cups rice krispies treats
  • Method
  • Line an 8 inch square cake tin with greaseproof/baking paper
  • Put the two tablespoons of butter in a pot and melt it over a low heat on the stove.

  • Finally add in your Rice Krispies and mix until they are fully coated in the melted marshmallow.

Marshmallow rice Krispies treats are used by a lot of cake decorators to make some complex designs because it holds together a lot more and quite easy to sculpt. I baked the cake below and I used rice Krispies treats for the ice cream cone because I did not want to bake another cake or cupcakes to form the ice cream part.
