1/2 c. butterscotch chips
1/4 c. butter
3/4 c. flour
1/3 c. brown sugar
1 tsp. baking powder
1/2 tsp. vanilla
1 egg
1 c. miniature marshmallows
1 c. chocolate chips
1/4 c. chopped nuts

Preheat oven to 350 degrees. Grease a 9 inch pan. Melt butterscotch chips and butter over low heat in a double boiler; cool. Pour butterscotch mixture in a large mixing bowl. Add flour, brown sugar, baking powder, vanilla and egg to cooled mixture, blending with a wooden spoon. Fold marshmallows, chocolate chips and nuts into batter, using five strokes only. Pour into prepared pan. Bake at 350 degrees for 20 to 25 minutes. Do not over-bake! Center will be jiggly, but becomes firm upon cooling. Cool on wire rack before cutting.
