Healthy Cinnamon Apple Banana Muffins

Directions

1. 1
   Preheat the oven to 350F. Lightly coat 12 muffin cups with nonstick cooking spray.
2. 2
   In a medium bowl, whisk together the flour, cinnamon, allspice, baking powder, baking soda, and salt. In a separate bowl, whisk together the butter, eggs, vanilla, and vinegar.
3. 3
   Mix in the Greek yogurt, stirring until no large lumps remain.
4. 4
   Mix in the mashed banana and maple syrup. Alternate between adding the flour mixture and milk, beginning and ending with the flour mixture, and stirring just until incorporated. (For best results, add the flour mixture in 3 equal parts.) Set aside 2 tablespoons of the apple, and gently fold in the rest.
5. 5
   Divide the batter between the prepared muffin cups, and gently press the remaining apple into the tops.
6. 6
   Bake at 350F for 18-21 minutes, or until the tops feel firm to the touch and a toothpick inserted into the center comes out clean. Cool in the pan for 5 minutes before carefully transferring to a wire rack to cool completely.
