Oat Flour Banana Bread (No Wheat Flour)
A tender, naturally wheat-free banana bread made entirely with oat flour. Weighed, tested, and written in grams first — because oat flour is one of the most inconsistently scooped flours there is.
Also known as bananas, fresh banana.
Whole bananas, by size and by the cup. "Three medium bananas" is the vaguest instruction in baking — it can mean anywhere from 240 g to 400 g of fruit.
Use 1:1 by weight
Replaces banana's moisture and binding in quick breads, without the banana flavor or its sweetness. Add a little sugar to compensate.
Common single-unit weights for banana — useful when a recipe calls out a specific count instead of a volume.

Ingredient-specific, density-based conversions for baking
Published values, quoted at the exact measure each source lists. Sources round differently and assume different fill techniques — which is why they rarely agree to the gram.
| Source | Listed measure | Weight |
|---|---|---|
| USDA FoodData Central | 1 medium (peeled) | 118 g |
| USDA FoodData Central | 1 cup (sliced) | 150 g |
| USDA FoodData Central | 1 cup (mashed) | 225 g |
CupOrGram standardizes on 150 g per cup (9 g per tablespoon, 3.1 g per teaspoon) and uses that single value on every page — how we reconcile the sources.

Room temperature until ripe, then refrigerate to hold (the skin blackens; the flesh does not). Freeze peeled and mashed for baking.
A banana's weight varies by more than 80% between an extra-small (81 g) and an extra-large (152 g) fruit, which is why banana bread recipes are so inconsistent. Ripening also matters chemically, not just for sweetness: starch converts to sugar, so a heavily freckled banana browns faster and adds more sweetness at the same weight.
For purees: moisture differences can thin batter unexpectedly.
For dried fruits: hydration level impacts chew and spread.
For fruit swaps: verify sweetness and acidity changes in the final bake.
Baseline reference: 1 cup banana = 150g. In real kitchens, a practical range is usually 140g-161g per cup (7% band).
Why this happens: water content and texture vary by ripeness, processing, and brand.
Figures use the US cup (236.6 ml).1 cup of banana weighs 150 grams.
