Peanut butter cups to grams converter
Use this peanut butter cups to grams converter when a recipe gives volume but you want the repeatability of a kitchen scale. The page is pre-filled with peanut butter and uses 258 grams per US cup as the working density, so cup, tablespoon, teaspoon, milliliter, fluid ounce, and gram conversions stay tied to the ingredient instead of a generic liquid assumption. Peanut butter traps air and clings to cups; stir separated jars first and weigh for the cleanest result. It is most useful for cookies, sauces, smoothies, energy bites, sandwich filling, and nut butter substitutions, especially when scaling a recipe up or down before mixing.
