Ingredients you’ll need

To get started making this recipe, you’ll first want to gather all your ingredients first. Get the full recipe in the recipe card below.

Ingredients you’ll need for this recipe

  • 2 sticks butter – Use real butter, no margarine here.
  • 2 cups natural peanut butter – Use the creamy peanut butter. You can use chunky but your peanut butter fudge will not be as smooth and creamy.
  • 2 cups powdered sugar – If you choose to use regular peanut butter instead of natural, you will need to adjust the amount of powdered sugar you use. See the note below.
  • 2 tablespoons vanilla extract

Yep, with just four ingredients, you can make Peanut Butter Fudge in your kitchen instead of going out and buying it from a store! It will taste even better and be way fresher when you’re making it from scratch. I also like to add peanut butter chips to make the recipe even more delicious from time to time. The peanut butter flavor in this fudge is immaculate.

How to adjust the powdered sugar if not using natural peanut butter

If using regular peanut butter then use less powdered sugar. About 3 1/2 cups per one cup butter ratio.
