In a large bowl, whisk the banana, maple syrup, vanilla, and egg until well combined.
2-3 ripe bananas, ½ cup maple syrup, 1 teaspoon vanilla, 1 egg
Add the cinnamon, nutmeg, salt, flour, oats, and flaxseeds. Mix well.
1 teaspoon cinnamon, ½ teaspoon ground nutmeg, ¼ teaspoon kosher salt, 1 ½ cups whole wheat pastry flour, 1 cup old-fashioned oats, ½ cup ground flaxseeds
Stir in the baking powder until just combined.
2 teaspoon baking powder
Pour in a greased 11 x 7 baking sheet.
Bake for 25-30 minutes until a toothpick comes out clean when stuck in the middle. Mine took exactly 26 minutes.
You probably should let it cool but I couldn't wait. We dug right in.
