The Best Sandwich Cookie

By Chayil (Guest Post)

1. "4 eggs"
What size eggs? Extra-large, which I buy, are about twice the amount of eggs that small or extra-small eggs will give. This could greatly affect the outcome of the recipe.

2. "Mix all together." Everything from the cake mixes to the food coloring, or do you mean mix all the cookie ingredients only? Lots of recipes with a 'base' (cookie, cake, pie, hoagie, pasty) and a 'filling' put the directions for the base right after the ingredients for the base and then the directions for the filling directly after the ingredients for the filling.

3. "Flatten with a fork."
How thick? One inch (thick cookies) is pretty far gone from paper-thin like fillo dough or eighth-inch thick like an Oreo or the cookies in an ice cream sandwich.

4. "Add powdered sugar until it (filling) is thick." How thick? Play-dough consistency, cake frosting consistency, runny omelette consistency, hard dough consistency, soft dough consistency?
