Rocky Road Caramel Brownies (without nuts)

1 box Betty Crocker's Fudge Brownie mix
1 cup marshmallows
1 1/2 cup semi sweet chocolate chips
Enough melted caramel to drizzle over 13 x 9 inch brownie pan

Prepare brownies as directed on the box. Add about half of the chocolate chips. Bake until toothpick can be inserted and come out dry. Sprinkle the marshmallows and remaining chocolate chips over the brownies. Return to the oven for about 3-4 minutes or until marshmallows begin to melt a little bit. Let cool. Drizzle caramel over brownies and serve. Warning: These are extremely rich and messy. :)
Tip: Use a slightly smaller pan so the brownies are thicker.

Hope you enjoy my little brownie invention!
