Double Frosted Brownies

This recipe came from http://www.tasteofhome.com/.  It is a very rich dessert.

1 package fudge brownie mix (13x9 inch pan size)
1/2 cup butter, softened
1 1/2 cups powdered sugar
2 tablespoons instant vanilla pudding mix
2 to 3 tablespoons 2% milk
1 can (16 ounces) chocolate fudge frosting

Prepare brownie mix according to package directions.  (I bought a Duncan Hines fudge brownie mix.  It called for 2 eggs for fudge like brownies or 3 eggs for regular brownies.  Since the Double Frosted Brownies called for fudge frosting, I choose to use 2 eggs for more fudge-ness.)  Spread the batter into a greased 13x9 inch baking pan.  Bake at 350 degrees for 25-30 minutes or until toothpick inserted 2 inches from side of pan comes out clean.  Cool completely on wire rack.  In a large mixing bowl, beat butter, sugar, and pudding mix until blended.  Add enough milk to achieve spreading consistency.  Frost brownies.  Cover and refrigerate for 30 minutes.  Spread with fudge frosting.  Cut into bars.  Store in the refrigerator.
