Chocolate Peanut Butter Bars

This is a few recipes I found online mixed together: (cooks.com and verybestbaking.com)

Ingredients:
1.5 cups creamy peanut butter
1/2 cup and 2 tablespoons softened butter (I use mix the salted and unsalted)
2 cups powdered sugar
3 cups graham cracker crumbs
2 package (12 oz) Semi-Sweet Chocolate chocolate chips

Directions:

1. Have ready 9x13 inch greasted baking pan.
2. Mix confectioners' sugar, graham crackers, peanut butter and butter in medium bowl until well blended.
3. Scrape into baking pan and press into even layer.
4. Melt chocolate (I put chocolate in a bowl, and place it over a pot of boiling water. It's really easy to burn chocolate if you do it in the microwave).
5. Spread melted chocolate over top.
6. Refrigerate at least 2 hours until chocolate is firm.
7. Let stand 10-20 minutes at room temperature before cutting into bars.

ALTERNATE (if you want it to be more like a pie):
Use 2 cups of graham cracker crumbs, and place into a graham cracker pie crust.
