1/2 c. butter
1 (12 oz.) pkg. butterscotch chips
1/2 c. firmly packed brown sugar
2 eggs
2 tsp. baking powder
2 tsp. vanilla
1 (12 oz.) pkg. chocolate chips
2 c. miniature marshmallows
1 c. chopped pecans or walnuts
1 1/2 c. flour
1/2 tsp. salt

In medium saucepan, melt butter over medium heat; add butterscotch chips and brown sugar, stirring until melted. Remove pan from heat; add eggs; stir. Add flour, baking powder and salt; mix thoroughly. Stir in vanilla; set aside until cool.

When cool, stir in chocolate chips, marshmallows and nuts; spread in a greased 9 x 13 inch pan. Bake 25 minutes at 350 degrees. Remove from oven and let cool thoroughly before cutting into squares. These are yummy and terribly rich.
