Method
- Heat the oven to 350°F (175°C). Line a light-colored 9-by-5-inch metal loaf pan with parchment paper, leaving an overhang on the long sides.
- Peel and mash the bananas. Weigh the mash; the provisional formula targets about 225 g (1 cup). Record the actual amount.
- In a medium bowl, whisk together the superfine blanched almond flour, baking powder, salt, and optional cinnamon.
- In a large bowl, whisk together the mashed banana, eggs, brown sugar, cooled melted butter, and vanilla until combined.
- Add the dry ingredients to the wet ingredients. Stir just until no dry pockets remain; the batter will be thicker than a wheat-flour batter.
- Scrape the batter into the prepared pan and smooth the top. Keep the first test loaf plain so you can assess the base formula.
- Bake for a provisional 45–55 minutes, beginning to check near 45 minutes. A tester inserted in the center should come out without wet batter. If the top gets deeply golden before the center is done, tent it loosely with foil.
- Rest the loaf in the pan for 15 minutes. Transfer it to a wire rack and cool completely before slicing.
Notes
TEST DRAFT ONLY: This formula has not been kitchen-tested. The starting formula uses about 225 g (1 cup) of peeled, mashed banana, 270 g of superfine blanched almond flour, and a light-colored 9-by-5-inch metal loaf pan. Record the banana weight and almond flour brand during testing.
Almond flour: Use finely ground blanched almond flour, not coarse almond meal. Almond flour behaves differently from wheat flour and is not a one-for-one substitute.
Banana weight: Weigh the peeled, mashed fruit. The starting formula targets about 225 g; do not assume every pair of bananas weighs the same.
Doneness: The 45–55-minute bake window is provisional. Begin checking near 45 minutes. A center tester should come out without wet batter. Tent the top loosely with foil if it browns before the center is done.
Cooling: Rest the loaf in the pan for 15 minutes, then move it to a rack and cool completely before slicing. The provisional WPRM total includes the 15-minute pan rest but not the full rack-cooling time.
Variations: Test the plain base loaf first. Do not add chocolate chips, nuts, or other substitutions until the base formula is evaluated.
Nutrition and yield: Confirm the actual slice count and serving size, then calculate nutrition from the final ingredient weights and brands. WPRM Servings is set to 8 per site convention; Advanced Servings stays blank.
