Are Oats Gluten-Free?
Well, you might be thinking, since you want to make gluten-free oatmeal, are oats and oatmeal even gluten free?
The short answer to that question is yes. Oats are gluten-free. They are naturally gluten free.
However, most oats are manufactured in industries where they also produce barley, wheat, and rye.
This means that cross-contamination is very likely to happen. So, I will strongly recommend you go for oats that are certified gluten-free from purity protocol oats.
Purity protocol oats are the safest because they are tested for gluten and also grown in a dedicated gluten-free field.
Furthermore, you should also know that not everyone following the gluten free diet can take gluten free oats. Some people can’t tolerate gluten-free oats.

Healthy Oatmeal Cookie Recipe Substitutions
Oats
You can use either traditional rolled oats or quick cook oats. However, I recommend you go for the old-fashioned oats, I prefer their texture and appearance. And I will strongly suggest that you stay clear of instant oatmeal and steel-cut oats.
Baking Soda & Baking Powder
I strongly suggest that you don’t substitute baking soda or baking powder.
Eggs
Eggs give this healthy and simple recipe a better texture. However, this can be made vegan, but I recommend making this recipe with eggs.
Vanilla Extract
You can skip the vanilla extract. However, it helps add flavor to the recipe.
Add-Ins
For an extra special treat, add walnuts, ¼ cup of chopped pecans, or ¼ cup of chocolate chips. You can also add any favorite nuts or seeds of your choice. This is for an additional crunch.
