Homemade Peanut Butter Cups

I thought these were a little on the sweet side, next time I will reduce the amount of sugar and use dark chocolate.

Ingredients:
2 c. milk chocolate chips
2 T. shortening
1/2 c. butter
1/2 c. peanut butter
1 c. powdered sugar
2/3 c. graham cracker crumbs

Directions:
Melt chocolate chips and shortening over low heat in a heavy saucepan.  Stir occasionally until smooth, 3-5 minutes.
Coat 30 mini cupcake liners with about 1 teaspoon of the melted chocolate.  Refrigerate until hardened.
While the liners are chilling, combine butter and peanut butter in a saucepan. Cook over medium heat, stirring occasionally until melted 4-6 minutes.  Stir in the powdered sugar and graham cracker crumbs.  Press about 1/2 tablespoon of the filling into each chocolate cup.  Spoon about 1/2 melted chocolate on top of the filling.  Spread to cover.  Refrigerate until firm and then carefully peel off paper cups.  Store refrigerated.
