Healthier Oatmeal Cookies
With some simple swap outs, you can make a healthier version of these oatmeal sandwich cookies.
Applesauce
This is a classic trick for making things a little more healthy!
- Swap out half of the butter in the original recipe with applesauce.
Flour
Exchange the all-purpose flour in this recipe for whole wheat flour or your flour of choice. Since the main bulk of these cookies is from the oats, the flour can be easily swapped out without much alteration to the cookies.
Sugar Substitutes
There are so many substitutions for sugar that you can get your hands on now. When choosing a sugar substitute make sure you check the ratio of the substitute compared to regular sugar. They are often not a 1:1 replacement.
This is a list of my commonly used sugar substitutes and how much to use!
