Preheat oven to 350°F. Grease and line a 9-inch round cake pan with parchment paper.
02 -
In a large bowl, thoroughly mash the ripe bananas until smooth with some small lumps.
03 -
Add softened butter, maple syrup, eggs, and vanilla extract to the mashed bananas. Whisk until just combined without overmixing.
04 -
In a separate bowl, combine all-purpose flour, whole wheat flour, ground cinnamon, baking powder, baking soda, and salt. Stir until well blended.

Gently fold the dry ingredients into the banana mixture using a spatula, mixing only until no visible dry spots remain and maintaining a thick, lumpy batter.

Transfer batter to the prepared pan and smooth the surface. Bake for 35–40 minutes or until a toothpick inserted into the center emerges with just a few moist crumbs.
07 -
Allow the cake to cool in the pan for 10 minutes, then carefully transfer to a wire rack. Serve warm, optionally spreading butter on each slice.
