1-1/2 cups graham cracker crumbs (about 1 1/2 whole packages or 1/2 a box)
1-1/2 cups powdered sugar
3/4 cup peanut butter
1 cup and 2 tablespoons semisweet chocolate chips
3 tablespoons peanut butter
In a bowl, mix together the butter, graham cracker crumbs, powdered sugar, and 3/4 cup peanut butter until well blended. Press evenly into the bottom of an ungreased 8x8 inch pan.
Melt the chocolate chips with the remaining peanut butter (can be done in microwave or using a double boiler) stirring occasionally until smooth. Spread over the peanut butter mixture. Refrigerate for at least one hour before serving.
**If using the microwave to melt, use caution not to burn the chocolate chips. If you don't have a double boiler, you can put a glass bowl in a pot of boiling water on the stove.
