You bundled up the kids for the first snow fall of the year and now it is time to indulge in a snowball of your own, with none of the cold and all of the fun. Whisk yogurt and cream cheese until smooth. Cut the brownie in half and shape into 2 (snow) balls. Spoon the yogurt mixture on top of each ball and sprinkle with edible glitter. Enjoy while warming hot chocolate for when the elves come back inside.
