*See post for directions on how to make your own butternut squash puree.
**You can substitute coconut butter if desired, but don't use applesauce or yogurt - the final product will be too moist.
***For a sweeter muffin, increase the sugar to 1/2 cup.
Store in an airtight container lined with paper towels for 1-3 days. You can also freeze for optimal taste and texture, especially if you do not plan on eating the whole batch within 3 days.
