The recipe was originally for mini muffin cups. They are way cute that way, too! You'll need:
1 box fudge brownie mix
8 oz. cream cheese
1/4 c. powdered sugar
2 squares (1 oz. each) white baking chocolate
2 tbsp. milk
1 c. cool whip, thawed
Prepare brownie mix according to package directions. Put liners in cupcake tins and spray generously with Pam. Fill each muffin tin 2/3 full with batter. Bake at 350 for 17 minutes (or until done). If doing mini muffins, bake at 325 for 14 minutes (or until done). Immediately after removing from oven, press tops of brownies down to make an indentation (I used the back of a tablespoon, but you'd want something smaller for the mini muffin size). Cool.
Microwave the white chocolate and milk together for 1 minute; stir smooth. If needed, microwave at additional 30 second intervals until stirs smooth. Combine cream cheese and powdered sugar; beat until smooth. Add white chocolate mixture. Fold in 1 c. cool whip.Pipe frosting into brownie cups and top with a slice of strawberry (or two!).
