In large saucepan melt butter over low heat. Add marshmallows and stir until completely melted. Remove from heat.
Add food coloring to melted marshmallows and mix.
Next, add Rice Krispie cereal. Stir until well coated.
Tree Instructions
Coat hands with non-sticking cooking oil.
Shape Rice krispie treats into cone shape trees.
Add crushed peppermint candies to the newly sculpted trees. Cover the whole tree surface.
Remove the tin foil wrapper from the peanut butter cup. Place the candy at the bottom of the tree. Make sure to place it in the middle of the tree bottom. If the tree is not balanced, you'll have to place the candy in a spot so that the tree doesn't fall over.
Also, if it doesn't stick to the bottom, place some peanut butter in between the candy and tree. The peanut butter will help the candy to stay in place.
Pipe base of tree and top with buttercream icing. This step is optional. I also place a little candy star at the top of the tree.
