Butterfinger Stuffed PB Rice Crispy Treat

I was surprised by how good the butterfinger and peanut butter rice crispy flavor combination was in this cookie. I sent these cookies to my sister for her birthday and her and her husband loved them.

Recipe
10 oz marshmallows
1/2 cup peanut butter
6 cups rice crispy's

Microwave 10 oz of marshmallows for a little over a minute until they're melted. Stir in 1/2 cup peanut butter. Added 6 cups of rice crispy's. Poured 1/2 the mixture into a brownie pan. Add 2 butterfinger candy bars (spaced apart), then top them with the remaining crispy cookie mix.
