- Preheat the oven to 350°F, and lightly coat 12 muffin cups with nonstick spray.
- In a medium bowl, grind oats and then stir together the oat bran, Greek yogurt, milk, and vanilla. Let the mixture rest for at least 10 minutes while preparing the remaining ingredients.
- In a separate bowl, whisk together the flour, baking powder, cinnamon, and salt. In a third bowl, whisk together the butter and egg white. Stir in the molasses and maple syrup. Add the oat bran mixture, stirring until fully incorporated. Add the flour mixture, stirring until just incorporated. Fold in the peaches.
- Evenly divide the batter between the prepared muffin tins. Bake at 350°F for 21-24 minutes or until the tops feel firm to the touch. Cool in the muffin cups for 5 minutes before carefully transferring to a wire rack.
