Peanut Butter Squares

In a large mixing bowl, combine the confectioners sugar, brown sugar and graham cracker crumbs.

Using a wooden spoon and rubber spatula, add peanut butter (take off cap and foil, then zap in microwave for about 1 minute to soften).

Then add melted margarine (melt in microwave) and vanilla.

When mixture is well blended, spread into a 9 x 13-inch pan, using fingers to spread evenly.
