No-bake Chocolate Bars

My favorite goody recipe, and always a fabulous hit at parties!

1 cup butter
1/2 cup brown sugar
1 tsp vanilla
3 cups uncooked quick oats
1 cup semisweet chocolate chips (I always use milk chocolate) (can be doubled)
1/2 peanut butter (double this too!)

Grease 8-inch square baking pan. Melt butter in large saucepan over
medium heat. Add sugar and vanilla: mix well. Stir in oats. Cook over
low heat 2 to 3 minutes or until ingredients are well blended. Press
half of mixture into prepared pan. Use back of large spoon to spread
mixture evenly. Melt chocolate chips in small heavy saucepan over low
heat, stirring occasionally. Stir in peanut butter. Pour chocolate
mixture over oat mixture in pan; spread evenly with knife or back of
spoon. Crumble remaining oat mixture over chocolate layer, pressing in
gently. Cover and refrigerate 2 to 3 hours or overnight. Bring to room
temperature before cutting into bars. Bars can be frozen; let thaw at
least 10 minutes before serving.
