Then add 4 tablespoons of milk, the food coloring, and almond extract to the butter and mix together.
Add the powdered sugar, a half-cup at a time, to avoid a mess.
Add up to 2 tablespoons of the remaining milk to reach the frosting consistency you like. You can also add more food coloring if needed to darken the color of the frosting.
These Sugar Cookie Bars can be frozen. It is preferred that the dough be frozen prior to cooking or the baked cookies be frozen before frosting. For full instructions on freezing, go to: https://overthebigmoon.com/soft-sugar-cookie-bar-recipe/.
