2-Ingredient Peanut Butter Fudge Ingredients

Let’s look at what each ingredient does in this recipe:

  • Creamy Peanut Butter: Forms the base of the fudge, providing a rich, nutty flavor.
  • Sweetened Condensed Milk: Adds sweetness and a creamy texture, helping to set the fudge as it chills.

Variations and Substitutions

Personalize your fudge with these easy tweaks:

  • Firmer Fudge: This is a soft creamy fudge with the texture of a soft caramel. I love this texture, but it’s best served cold from the fridge. If you’d like to store it at room temperature or give it away in cookie boxes, add 1 cup of peanut butter chips or white chocolate chips to set it up firmer.
  • Crunchy Peanut Butter: For a bit of texture, use crunchy peanut butter instead of creamy.
  • Chocolate Chips: Mix in or melt chocolate chips for a chocolate peanut butter version.
  • Vanilla Extract: Add a splash for enhanced flavor.
  • Toppings: Sprinkle sea salt, mini chocolate chips, chopped Reese peanut butter cups or chopped nuts on top before chilling for added crunch.

5 Common Mistakes When Making 2-Ingredient Peanut Butter Fudge

Just skimming through? Here are some quick answers to the commonly-asked questions about 2-Ingredient Peanut Butter Fudge:

What is peanut butter fudge made of?
Peanut butter fudge is typically made of peanut butter and sweetened condensed milk, creating a creamy, sweet treat.

Yes, you can use almond milk condensed milk for a dairy-free version, though the texture may vary slightly.

How can I tell when the fudge is set and ready to cut?

How long does this fudge last at room temperature?
It can last at room temperature for a few days, but for longer storage, refrigeration is recommended.

Notes

*In the US, sweetened condensed milk is measured by weight and a can is 14 oz; elsewhere it’s measured by volume and it’s 300 mL. It is the same quantity inside the can. This confuses some people because 14 fluid ounces is not equal to 300 mL, but ounces by weight are different from fluid ounces (it depends on the product density).
This is a soft, creamy fudge with the texture of a soft caramel candy. I love this texture, but it’s best served cold from the fridge. See notes in post about how to make it a firmer fudge if you prefer.
Add a pinch of salt or vanilla extract for an enhanced flavor.
Store in an airtight container in the fridge for a firmer fudge. It’s very soft at room temperature.
Experiment with toppings like chocolate chips or crushed nuts for added texture and flavor.
  • To add a topping like sprinkles, nuts, or mini chocolate chips, sprinkle over the fudge while it’s still warm, before setting. 
  • To add sea salt, add once the fudge is set or it will dissolve on top.
