Sacrament Meeting Brownies

I haven't made these yet, but they sounded SO good! I think I'm going to make them when I have to take a dessert somewhere.

2/3 C Cocoa
2/3 C Shortening, Melted (NOT NOT NOT butter flavored)
4 Eggs
2 C Sugar
1 teaspoon Vanilla
1 1/2 C flour
1 teaspoon baking POWDER
1 teaspoon Salt
1 to 1 1/2 C miniature marshmallows
1 C Chopped nuts (optional)

Mix Cocoa and melted shortening in bowl. In seperate bowl beat eggs, sugar and vanilla. Add to cocoa mix. Add dry ingredients EXCLUDING marshmallows to cocoa mixture. Mix well. Stir in marshmallows. Pour into 9x13 pan and bake @ 350 for 25-35 minutes. Your fork or toothpick won't come out super clean because of the marshmallows.
