Prepare Frosting: Once your blondie has cooled, make your frosting. Using an electric mixer, beat wet ingredients together (choose from option 1 or option 2 icing) with contents of clear bag you removed in step 3. If your mixture is too thick to your liking, add in ½ tablespoon milk at a time until your frosting is your desired spreadable consistency. Spread icing on cooled blondie. Optionally garnish with chopped crystallized ginger for extra fancy.
