Ingredient Substitutions
Brown Sugar
Use white sugar if you don’t have brown sugar. The cookies will be slightly less chewy but still taste great.
Quick-Cooking Oats
Regular rolled oats work if you don’t have quick-cooking oats. The texture will be a bit chunkier.
Vegetable Shortening
Replace the shortening with an equal amount of butter in the filling. The creme will be slightly softer but still delicious.
Marshmallow Creme
Use marshmallow fluff as a substitute. The filling will have the same taste and texture.
