How to make Halloween Rice Krispie Treats with Homemade Marshmallow

  • Line a 13×9 Glass Baking Pan, with deep sides, with parchment paper that is buttered well.  If you skip this set it will be terribly difficult to get the treats out of the pan, and off the paper when you cut them. (trust me on this one as I forgot on one of my batches)

  • Melt one 10 oz bag of marshmallows in a large saucepan on the stove with 3 tablespoons of butter. Do not walk away and stir as the marshmallows melt.
  • When the marshmallows are melted quickly add 6 cups of Rice Krispies and stir.
  • Quickly transfer the mixture to the prepared pan.Fun Halloween Rice Krispie Treats with Marshmallow Frosting
  • Take a buttered spatula or your hands that are well-buttered and flatten out the Rice Krispies mixture in the pan.
  • Set this aside.
  • Next, make homemade marshmallows for the topping. Follow the recipe in my post How To Make Homemade Heart Shaped Marshmallows.
  • The only change from this recipe is to leave out the food coloring.
  • You will also want to only whip the mixture in your mixture for 7 to 8 minutes at the most. You want to be able to spread the marshmallows for this recipe.  At 6 minutes start testing so they do not become too stiff.
