Related to Peanut Butter
Almond Butter
Almond butter swaps 1:1 by volume for peanut butter and is a touch lighter per cup (256 g vs 268 g). It tastes milder and slightly sweeter, so cookies and bars come out less salty; texture and bake time stay the same. Pick unsweetened to match peanut butter most closely. See our Almond Butter converter.
Sunflower Seed Butter
Sunflower seed butter is the nut-free 1:1 swap, lighter per cup (250 g vs 268 g). It works in the same cookies, bars, and sauces with an earthier, more savoury taste. Note it can react with baking soda and tint a bake slightly green, which is harmless. See our Sunflower Seed Butter converter.
Hulled Tahini
Hulled tahini swaps 1:1 for peanut butter in satay, sauces, and bars, and pours looser (240 g vs 268 g per cup). It is more savoury and a little bitter, so add a touch of honey in sweet bakes; both are smooth pastes that bind a recipe the same way. See our Hulled Tahini converter.
Butter
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 what 1 ounce of butter is in cups.
Peanuts
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 what 1 ounce of peanuts is in cups.
