1.) To prep the sweet potatoes (this can be done a day or so ahead if you want to get a head start). Pierce the potatoes with a fork and place on a foil-lined baking sheet. Bake at 400 degrees for approximately 45 minutes, or until the inside is soft when poked with a fork. Remove and let cool. When the potatoes are cool, peel off the skin and mash the sweet potato with a fork or masher until any big lumps are gone. Measure out 1 cup worth of filling.
2.) To make the muffins: In a large bowl combine all the ingredients and mix until well incorporated.
3.Pour into muffin tins/cups. Bake at 375 for approximately 15 minutes. Enjoy!
