Key Ingredients for Peanut Butter Fudge
You'll find the exact measurements in the recipe card, but here's a closer look at key ingredients and why I use them.
- Butter & Peanut Butter Base: I use unsalted butter and peanut butter because they melt together smoothly and create the rich base that gives this fudge its soft, creamy texture.
- Sweetness & Structure: Powdered sugar sweetens the fudge and helps it set properly, which is what makes this a reliable 5-ingredient peanut butter fudge.
- Flavor Balance: A little salt and vanilla paste make a big difference here. They round out the sweetness and give the fudge a fuller flavor.
How to Make Peanut Butter Fudge
You can find the complete printable recipe with measurements below, but for now, here's a quick overview of how it goes:

1. Melt and Combine the Base: In a saucepan over medium heat, melt the butter with the peanut butter, stirring until smooth. Bring to a gentle boil, then remove from heat.
2. Mix in the Remaining Ingredients: Stir in salt, vanilla paste, and powdered sugar until fully mixed and smooth.
3. Pour and Set the Fudge: Pour the mixture into a parchment-lined square baking dish, spread evenly, and let cool at room temperature. Refrigerate for 1 hour or until firm.
4. Slice and Serve: Lift the fudge out, cut into squares, arrange on a plate, and serve.
Variations
- Chocolate Top: Spread a thin layer of melted chocolate over the top before chilling.
- Crunchy Peanut Butter: Swap smooth peanut butter for crunchy if you want extra texture.
- Sea salt Finish: Add a light sprinkle of flaky salt on top for a sweet-salty contrast.

My Tips for Peanut Butter Fudge
Do not Overheat the Mixture: I stop once everything is melted and the mixture reaches a gentle boil, because too much heat can affect the final texture.
Mix while Warm: I find the powdered sugar blends much more smoothly when the mixture is still warm.
Chill before Slicing: Letting the fudge cool first at room temperature and then in the fridge gives cleaner squares.
Storage
I keep mine in a sealed container in the fridge; it stays fresh for a week, and you can even freeze it for longer.
