1 c. crunchy or regular peanut butter
1 lb. box confectioners' (powdered) sugar
1/4 tsp. salt
1/2 c. cocoa

Melt butter and stir in peanut butter and salt. Remove from stove. Beat in sugar and cocoa (can put cocoa in half of mixture for 2-tone look). Spread in 13-inch Pyrex dish. Cool until set. May pre-cut squares and set pecans or walnuts on top of each square, if desired.
