Store your Keto Fat Bombs in the fridge, in an airtight container. They will keep easily for 7-10 days without drying out. They can also be frozen, to be used as needed.
My favorite vanilla collagen in from Primal Kitchen. If you use a plain, unflavored collagen powder you may want to add a bit of additional sweetener. 2 -3 Tablespoons of powdered erythritol is my top choice, or 1/4 teaspoon of liquid stevia will also work well.
I just love all of the health benefits of collagen protein, but you can absolutely use plant-based protein powder instead of collagen if you prefer. If you substitute a plant-based protein powder, reduce the amount called for in the recipe. Otherwise, it can make the dough a little difficult to bind and make the finished Bombs too hard.
