Chocolate Marshmallow Bars

In honor of The Office season premiere- I just had to find something sinfully delicious to make. This recipe fit the bill! These are very good and I will definitely make these again. I found the recipe on Good Eats n' Sweet Treats.

Deluxe Chocolate Marshmallow Bars
from Esther Shank, Taste of Home's Holiday Get-Together 2006
3/4 cup butter
1-1/2 cups sugar
3 eggs
1 tsp vanilla extract
1-1/3 cups all purpose flour
3 tbsp baking cocoa
1/2 tsp baking powder
1/2 tsp salt
4 cups miniature marshmallows

Topping:
1-1/3 cup chocolate chips
1 cup peanut butter
3 tbsp butter
2 cups crisp rice cereal

In a mixing bowl, cream butter and sugar. Add eggs and vanilla; beat until fluffy. Combine flour, cocoa, baking powder and salt; add to creamed mixture. Spread in a greased 9x 13 pan.
Bake at 350F for 18-25 minutes or until middle is set. Sprinkle marshmallows evenly over cake; return to oven for 2-3 minutes. Using a knife dipped in water, spread the melted marshmallows evenly over cake. Cool.
For topping, combine chocolate chips, peanut butter and butter in a small saucepan. Cook over low heat, stirring constantly, until melted and well blended. Remove from heat; stir in cereal. Immediately spread over bars. Chill.
