Marshmallow Brownies - cooking recipe

Ingredients

1 cup butterscotch chips (6oz)
1/2 cup butter
2 eggs
2/3 cup packed brown sugar
1 teaspoon vanilla extract
1 1/2 cups all-purpose flour
2 teaspoons baking powder
1/2 teaspoon salt
2 cups miniature marshmallows
2 cups milk chocolate chips (12oz)
1/2 cup chopped walnuts (we never use) (optional)

Preparation

In a small saucepan over low heat, melt butterscotch chips and butter.
Remove from heat and cool for 10 minutes.
In a mixing bowl, beat eggs, brown sugar and vanilla.
Add butterscotch mixture and mix well.
Combine flour, baking powder and salt.
Add to batter and mix well.
Stir in marshmallows, chocolate chips and nuts.
Spread into a greased 13X9 baking pan.
Bake at 325 degrees for 25-30 minutes or until brownies test done.
I watch for the sides to pull away from pan and it is\"set\" when the pan is jiggled back and forth.
The toothpick test works but not as well as the other because of the marshmallows.
Cool completely before cutting into bars.
