Method
- Heat the oven to 350°F. Line a 9-by-5-inch metal loaf pan with parchment, leaving an overhang on the long sides. Lightly oil the uncovered ends.
- Whisk the measured mashed banana, maple syrup, oil, soy milk, flaxseed, vinegar, and vanilla until evenly combined. Let stand for 10 minutes while preparing the dry ingredients.
- Whisk the flour blend, baking powder, baking soda, cinnamon, and salt in another bowl. Fold into the banana mixture until no dry pockets remain, then fold in the walnuts. The batter should be thick but spreadable.
- Spread evenly in the pan. Bake for 55–65 minutes, until the center springs back lightly and a skewer inserted into the middle comes out with a few moist crumbs but no wet batter. If the top browns early, loosely tent with foil after 40 minutes.
- Cool in the pan for 20 minutes. Lift onto a wire rack and cool for at least 70 minutes more before slicing into 10 pieces. Let the loaf finish setting rather than cutting it while hot.

Notes
Measure the banana: Bananas vary greatly in size. Measure 1 1/3 cups of mash; adding an extra banana can leave a heavy, damp center. Use soft, deeply spotted bananas for the fullest flavor.
Use a blended flour: Choose a gluten-free all-purpose baking blend containing rice flour, starches, and xanthan gum. Almond, coconut, and plain oat flour are not direct substitutes. Scoop flour into the cup with a spoon and level it without packing.
A softer slice: Ground flax supports the crumb, and cooling lets the starches finish setting. A warm slice can seem sticky even when the loaf is baked through; allow the full cooling time before judging the texture.
Walnut options: Pecans can replace the walnuts in the same amount. For a nut-free loaf, omit the nuts and check the flour and milk labels for your needs.
Keep and freeze: Once completely cool, wrap and keep at room temperature for up to 2 days or refrigerate for up to 5 days. Freeze individual slices for up to 2 months; thaw wrapped and gently warm before serving.
