Peanut butter is roasted peanuts ground into a thick, oily paste, sold smooth or crunchy. One metric cup (250 ml) of peanut butter weighs around 268 grams or 9.45 ounces. It is used in cookies, brownies, no-bake bars, satay sauce, and as a spread for toast and sandwiches.

Peanut butter is sticky and clings to measuring cups, so scooping reliably is hard. Weighing in grams gives accurate amounts without the mess of scraping out a cup.

Butter is a dairy fat that creams with sugar to build structure and lift, while peanut butter is an oily paste that adds dense flavour. They are close in weight (227 g vs 268 g per cup), so weigh when swapping in cookies and bars; expect a nuttier, denser result from peanut butter. See butter in US cups.

Peanuts are the whole form used for crunch and texture where peanut butter adds creaminess. A cup of peanuts (154 g) is much lighter than a cup of peanut butter (268 g); always swap by weight. See peanuts in US cups.

Almond butter is the milder, slightly sweeter nut-butter sibling, a touch lighter per cup (256 g vs 268 g). It swaps 1:1 by volume for peanut butter in cookies, bars, and sauces, with a milder, less salty flavour. See almond butter in US cups.

Sunflower seed butter is the nut-free stand-in, lighter per cup (250 g vs 268 g). It swaps 1:1 for peanut butter in school and allergy bakes, with an earthier, more savoury taste. See sunflower seed butter in US cups.

Hulled tahini is a smooth sesame seed paste, lighter per cup (240 g vs 268 g) and far more savoury than peanut butter. Swap by weight when using it in dressings, halva, or bars where a nut-free, bitter-edged paste suits the recipe. See hulled tahini in US cups.
