To make the buttercream frosting:
Using a hand mixer or a stand mixer fitted with the paddle attachment, beat the butter until smooth. Add in the powdered sugar and continue to mix until combined.
½ cup (113g) unsalted butter, 1 ½ cups (180g) powdered sugar
Add milk, one tablespoon at a time, and beat to achieve the desired consistency. Add gel food coloring, if using, and mix well. Spread frosting on cooled cookie base before slicing into bars.
1-2 tablespoons whole milk, food coloring
Notes
If you are not looking to make these bars gluten free, use all-purpose flour instead.
Be sure to follow the instructions on the package of Bob's Red Mill Egg Replacer. Once mixed with water, the egg replacer must sit for just a few minutes to thicken.
If you are not looking to replace eggs, you should be able to use 1 egg instead of the egg replacer.
If you accidentally thin your frosting out too much with the milk, add more powdered sugar in, one tablespoon at a time.
