Peanut butter is a pantry staple that makes an excellent sandwich filling, a quick snack, or a baking ingredient.

Because peanut butter is high in natural fats and often has added oil and sugar, a small amount can contain more calories than you might think.

I’ve put together this ultimate guide to help you find weights and calories for any serving and type of peanut butter, including creamy, crunchy, and natural peanut butter.
