It doesn't feel like fall unless my kitchen smells like pumpkin so these pumpkin muffins have been a staple at my house lately. This pumpkin muffin blows all the others out of the water and the graham cracker and walnut streusel sends it over the top. the real kicker though, and the secret to why they are so moist, is that these use coconut oil instead of vegetable oil so you can eat them guilt-free.
