Low Carb Iced Oatmeal Cookies are a favorite childhood cookie made gluten-free and lower in carbs.

These Low Carb Iced Oatmeal Cookies are only 3g net carbs per cookie and still have that great iced oatmeal cookie taste!
Remember the old-fashioned, store-bought, iced oatmeal cookies that you loved as a kid?
I loved that they didn’t have any raisins (I didn’t like raisins as a kid) in them. And they had this sweet icing on top that kids love (okay, I admit it, I still love that royal icing on cookies).

These lower carb versions of the old fashioned iced oatmeal cookies still use gluten-free rolled oats but not as much as in the traditional recipe but enough to give you the taste and texture you love and remember.
I realize that these are not grain-free, but they are gluten-free and surprisingly low carb considering there are gluten-free rolled oats used in the recipe.

Yes, GF oats are part of my emergency food supply, and because of the quarantine and having my hubby & teen son home, I was running out of other low-carb baking ingredients.
The good news is that these are still low carb, and my hubby & son loved these!
