Peanut Butter Fudge

1 & 1/2 sticks butter
1 box powdered sugar
1 & 1/2 cup creamy peanut butter
1 tsp. vanilla extract
1 (12 oz.) pkg. milk chocolate chips

Melt butter; add peanut butter, powdered sugar, and vanilla. Press into 9 x 13 pan lined with wax paper. (Add a little cooking spray to your pan before the wax paper to keep it in place.)

Melt chocolate chips and pour over pressed peanut butter.

Let cool, lift out of the pan by the wax paper, and cut into squares.
