Measuring Tip

Ripeness affects density. Riper fruit mashes more smoothly and packs more densely per cup than firmer fruit. Weigh for the most consistent results.

Frequently Asked Questions

About 10.32 oz, based on mashed banana having a density of 225g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 225 (grams per cup for mashed banana), then divide by 28.3495 to convert grams to ounces. For 1.3 cups: 1.3 × 225 = 292.5g, then 292.5 ÷ 28.3495 = 10.32 oz.
For the most accurate results, weigh mashed banana on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring cup and level it off with a straight edge rather than scooping directly.
