1 cup butterscotch chips
1/2 cup butter
1 1/2 cups flour
2/3 cup packed brown sugar
2 tsp baking powder
1/2 tsp salt
1 tsp vanilla extract
2 cups miniature marshmallows
2 cups milk chocolate chips
Preheat oven to 350°F. Lightly grease a 9x13 inch baking pan.
Melt butterscotch morsels and margarine in a large bowl in microwave. 30 seconds the first time and only 15 second intervals after that. Stir the mixture well and let it cool to lukewarm.
After the liquid mixture is cooled, mix flour, brown sugar, baking powder, salt, vanilla, and eggs into the butterscotch mixture; mix well.
Fold in marshmallows and chocolate morsels.
Spread batter into a lightly greased 9x13 inch pan.
Bake 25 minutes. Do not overcook! You want them moist and yummy.
