This recipe is modified from the one on Martha Stewart's website. Enlist your kids to help, I bet their favorite part will be painting the chocolate into the bottom of the paper cups.
(ingredients listed above)
1. Combine butter, sugar and peanut butter in a large bowl with an electric mixer on medium. Put the mixture in a pastry bag or use a large freezer Ziploc bag - simple cut off one of the bottom corners when you are ready to pipe the mix into the cups.
2. Melt the chocolate in a double broiler. Keep the chocolate over the warm water when working with it.
3. Use a small paint brush to paint the inside of the paper cups with chocolate, coat the bottom and sides well. Place the cups on a baking sheet when you finish each one. Put the baking sheet in the freezer for 10 minutes until the chocolate cups are firm.
4. Remove tray from freezer and pipe the peanut butter mixture 3/4 way full into each cup. Spoon melted chocolate on top of the peanut butter. Return to the freezer for 15-25 minutes. Store in the freezer until ready to serve.
