Why This Recipe Works
This peanut butter fudge recipe relies on the natural fats and proteins in peanut butter, combined with a sweet binding ingredient. When mixed and chilled, the mixture firms up beautifully into a smooth, sliceable fudge with a melt-in-your-mouth texture.
It’s a nearly foolproof method that requires no special tools, no cooking experience, and no guesswork—making it ideal for beginners and busy days alike.
Ingredients You’ll Need
- 1 cup creamy peanut butter
- 1 cup sweetened condensed milk or powdered sugar
Which should you choose?
- Use sweetened condensed milk for a softer, creamier fudge
- Use powdered sugar for a firmer, more traditional fudge texture
Both versions are delicious—you can choose based on your preference.
How to Make 2-Ingredient Peanut Butter Fudge
Step 1: Prepare the Pan
Line a small square baking dish with parchment paper or lightly grease it. This makes removing and slicing the fudge much easier later.
Step 2: Mix the Ingredients
In a medium bowl, combine the peanut butter and your chosen sweetener.
- If using sweetened condensed milk, stir until smooth and glossy
- If using powdered sugar, mix until thick and fully blended with no dry spots
Tip: If your peanut butter is stiff, microwave it for 10–15 seconds to make mixing easier.
Step 3: Spread the Mixture
Transfer the mixture into the prepared pan. Spread evenly and gently press it into the corners with a spatula.
Step 4: Chill Until Firm
Refrigerate for 1–2 hours, or until the fudge is firm enough to cut cleanly.
Step 5: Slice and Serve
Lift the fudge out using the parchment paper, cut into small squares, and enjoy.
Tips for Perfect Peanut Butter Fudge
- Use regular creamy peanut butter for best results (natural varieties may separate)
- Stir thoroughly to ensure a smooth, even texture
- Cut into small pieces—it’s rich and satisfying
- Store in the refrigerator for firmer, cleaner slices
Easy Variations to Try
- Chocolate swirl: Drizzle melted chocolate over the top before chilling
- Crunchy version: Swap in crunchy peanut butter
- Vanilla flavor: Add a splash of vanilla extract
- Salted finish: Sprinkle flaky sea salt on top before chilling
