Notes
*make sure your nut butter is runny. If it's too thick, you may want to melt in in the microwave for 30 seconds - 1 minute before adding it to the blender, food processor, or mixing bowl. **can be made vegan, just use flax eggs instead of regular eggs. Head to my Instagram, @CallasCleanEats, and see my highlight titled "flax egg" for a step-by-step tutorial on how to make a flax egg.
