Consider including 2-3 tablespoons of chia meal/flour when mixing your dry ingredients. Then, before incorporating your coconut oil, add a few tablespoons of water and mix well. The chia and water will “gel”, causing everything to stick together just a bit. Once you bake it, the gel will dry out and the granola will hold together a bit better.
I like using chia meal better than chia seeds. If you have a high powered blender, you can easily blend chia seed into meal. But, if you want to use the seeds whole, it will still work. Just takes a few extra minutes to “gel up”.
Don’t Forget the Mix-Ins
Feel free to add a few berries, raisins, dried cranberries, etc. but add them to each serving independently. Otherwise, the moisture in the fruit will make the granola go soft. Also, as mentioned earlier, pay attention to how your additions change your carb counts and overall keto macros.
