Gather the necessary ingredients: ripe bananas, almond flour, all-purpose flour, eggs, sugar, vanilla extract, baking powder, butter, salt, and chopped almonds.
Preheat your oven to 350°F (175°C) and grease or line a baking pan with parchment paper.
In a bowl, mash the ripe bananas with a fork until smooth. Set aside.
In a separate bowl, beat together the eggs, sugar, and vanilla extract until creamy. Add in the mashed bananas and melted butter, mixing well.
In another bowl, whisk together almond flour, all-purpose flour, baking powder, and salt.
Gradually fold the dry ingredients into the wet ingredients until just combined. Be careful not to overmix.
Pour the batter into the prepared pan, sprinkle chopped almonds on top, and bake for 25-30 minutes, or until a toothpick comes out clean. Let it cool before serving.
