Preheat the oven to 350F (177C) convection or 325F (163C) conventional and grease and line three 4 inch pans (or 1-2 6-inch pans) with baking spray and parchment paper.
In a medium bowl, whisk together the flour, cinnamon, baking powder, baking soda, and salt and set aside.
3/4 cup (90g) cups all-purpose flour, 1/2 tsp cinnamon, 1 tsp (4g) baking powder, 1/4 tsp baking soda, 1/4 tsp salt
In another bowl, whisk together the banana, maple syrup, egg and yogurt, until they’re completely smooth.
1/2 cup (125g) banana, 1/4 cup (78g) maple syrup, 1 large egg, 1/4 cup (56g) Greek Yogurt
Add the dry ingredients to the wet ingredients and fold just until they’re combined.
Distribute the batter evenly into the three pans, about 4 oz per pan and bake for approximately 18-20 minutes, until the center springs back when you press on it.
