These hearty muffins are chock-full of healthy goodness and fantastic flavor. I think they taste best warm with a small pat of butter or a drizzle of honey (or both). Or try them with a dollop of your favorite marmalade.
Preheat the oven to 400°F and line a 12 cup muffin tin with paper liners (or grease well).
Mix the all-purpose gluten-free flour, millet flour, buckwheat flour, almond flour, flaxseed meal, oats, brown sugar, baking powder, baking soda, sea salt, cinnamon, xanthan if using, walnuts and cranberries in a bowl and whisk to combine.
Stir in the sour cream, egg, mashed banana, apple sauce and honey with a rubber spatula until evenly incorporated.
Evenly distribute the batter in the prepared muffin tin (I like to use an ice cream scoop for this). Bake for 15-18 minutes, or until a toothpick inserted in the center of the muffin comes out clean.
