Five Ingredient Friday

My son made this in 4H two years ago and it is one of the kids' favorites. By the way, my son won a Grand Champion ribbon for it too!

Easy Microwave Peanut Butter Fudge

2/3 cup butter
2/3 cup peanut butter (chunky or smooth)
6 cups confectioners' sugar
1/3 cup milk
1 tablespoon vanilla extract

Place butter and peanut butter in a large microwave safe bowl. Microwave on HIGH until butter melts (about 1 1/2 minutes); stir until well blended. Add remaining ingredients; stir until lumps of sugar disappear. Microwave on HIGH until soft but not bubbly (1 to 1 1/2 minutes); stir. Pour into buttered 9-inch square baking pan. Cover; refrigerate at least 1 hour. Cut into 1 inch pieces. Store in refrigerator.
