1 c. soft butter
1 c. crunchy peanut butter
1 box powdered sugar
1 1/2 c. crushed graham crackers
1 (12 oz.) pkg. chocolate chips or carob chips

Blend butter and peanut butter, work in powdered sugar and graham crackers (can be mixed with hands). Mix well. Press firmly in a 13x9 inch pan.

Melt chocolate chips and spread over the top. Different flavored chips may also be used.

For a better flavor and consistency, add a tablespoon of peanut butter to melted chocolate chips. It also helps the chips not to burn while you are melting them.
