Instructions:
Preheat the oven to 350°F (180°C). Mash the bananas, then peel and grate the apple using the large holes of a box grater.
1 cup (250g) mashed ripe bananas, 1 small apple
Place the eggs, oats, yogurt, vanilla, maple syrup, lemon zest, in a food processor. Blend until smooth (it doesn’t have to be perfectly smooth).
2 large eggs, 1 cup (90g) old-fashioned oats, ½ cup (120g) unsweetened yogurt, 2 teaspoons vanilla extract, ⅓ cup (110g) maple syrup, Zest of 1 lemon
Transfer the mixture to a large bowl. Add the mashed bananas and melted and slightly cooled butter.
6 tablespoons (85g) melted butter
In a medium bowl, stir together the whole wheat flour, cinnamon, salt, baking powder, and baking soda. Add the dry ingredients to the wet ingredients and whisk gently until almost combined.
1 cup + 2 tablespoons (155g) whole wheat flour, 1 teaspoon cinnamon, ¼ teaspoon salt, 1½ teaspoons baking powder, ½ teaspoon baking soda
Add the grated apple, pecans, and blueberries. Stir everything together by hand until just combined.
½ cup roughly chopped pecans, ¾ cup blueberries
Line a 12-cup muffin pan with paper liners — preferably slightly taller ones, like in the photo in the body of the post (regular liners will work as well, but some muffins may overflow just a little). Lightly spray the liners with baking spray — this step is optional, but the muffins are very moist and may stick a bit.
Divide the batter evenly between the muffin cups.
Bake for about 20-25 minutes (I bake mine for 22 minutes), or until a toothpick inserted in the center comes out clean (it can still be slightly sticky).
Let cool slightly (otherwise the paper liners can stick to the muffins) and enjoy!
