Melt butter, peppermint bark and chocolate chips in a double boiler, on medium heat. Slowly stir constantly. Once everything is evenly melted, take off heat and stir in brown sugar.
Transfer to the large mixing bowl to cool down a little bit so you don’t cook the eggs.
Once cooled, add eggs, one at a time, whisking after each addition.
Add peppermint extract and water.
Sift in flour and baking soda. Whisk until all evenly incorporated.
Fold in chopped PEEPS® marshmallow man into the batter until all evenly incorporated.
Pour batter into prepared baking pan.
Bake for 45-48 minutes.
Let brownies cool for 5-10 minutes and lay snowman on top, evenly, 3 per row. (Little tip: brush off as much sugar as you can off the bottom of each snowman so it melts some and sticks to the brownie better.) That way, when you cut the brownies, you will get a snowman per brownie.
