Peanut Butter Bars

From AllRecipes.com, submitted by Nancy.

Yield: 32 bars.

2 cups graham cracker crumbs
1 cup butter, melted
1 cup + 4 Tbs. peanut butter, divided
2 cups powdered sugar
1 1/2 cups semi-sweet chocolate chips

Use a food processor to pulse the graham crackers until fine.  Add the melted butter, 1 cup peanut butter, and powdered sugar.  Pulse until blended and smooth.

Press the peanut butter mixture into an ungreased 9x13 baking pan.

Melt the chocolate chips and remaining peanut butter in the microwave in 30 second increments until melted and smooth.  Pour over peanut butter layer and spread evenly.

Chill for 30 minutes or until set.  Remove to room temperature for at least 15 minutes before slicing into bars.

Notes:
- I read a suggestion to use all natural peanut butter, but I didn't try it because I have probably a three year supply of the regular stuff and didn't see a reason to go out and buy more!
- The recipe called for 1 1/2 cups butter, which I'm sure would have made the bars even creamier.
- The finer your crumbs, the smoother your peanut butter layer will be.  You don't have to use a food processor (you can do it all in a bowl or blender), but I recommend it.
- Each bar has about 200 calories in it, so devour wisely.
