Pumpkin Maple Muffins that are Gluten Free, Low FODMAP and Delicious! I will confidently say that this recipe is my favorite recipe that I have ever developed and this is probably the best pumpkin muffin I have ever eaten. Maybe that is hyping things up too much and I should set the bar lower, but honestly, these are that good! And the best part? They're made with homemade oat flour (read: rolled oats ground up using a mini food processor), so they are naturally gluten free
