If you’re making three double batches of peanut butter fudge, you’ll have enough rich, creamy fudge to fill several trays or serve a large crowd. This classic recipe comes together with simple ingredients and has that unmistakable peanut butter flavor everyone loves.
Ingredients
For 3 Double Batches
- 6 cups granulated sugar
- 1 ½ cups evaporated milk
- 3 cups creamy peanut butter
- 3 cups miniature marshmallows
- 3 cups semi-sweet chocolate chips
- 3 teaspoons vanilla extract
- ¾ teaspoon salt
How to Make Peanut Butter Fudge
1. Prepare the Pans
Line three 9 × 13-inch pans with parchment paper or lightly grease them. Leave some parchment hanging over the sides so the fudge can be lifted out easily once it has set.
2. Make the Sugar Mixture
Add the sugar and evaporated milk to a large, heavy-bottomed saucepan.
Place over medium heat, stirring frequently until the sugar dissolves and the mixture comes to a full boil.
Once boiling, continue cooking for about 5 minutes, stirring constantly so it doesn’t scorch.
3. Add the Peanut Butter and Marshmallows
Remove the saucepan from the heat.
Immediately stir in the peanut butter and miniature marshmallows. Continue stirring until everything is completely melted and smooth.
4. Add Chocolate and Vanilla
Stir in the chocolate chips, vanilla extract, and salt.
Mix until the chocolate has completely melted and the fudge is smooth and creamy.
5. Pour Into the Pans
Divide the mixture evenly between the prepared pans.
Smooth the tops with a spatula.
Allow the fudge to cool at room temperature until firm, or refrigerate it for several hours for faster setting.
6. Cut and Serve
Once completely firm, lift the fudge from the pans using the parchment paper.
Cut into small squares and serve.
Tips for Perfect Peanut Butter Fudge
- Use creamy peanut butter for the smoothest texture.
- Stir constantly while boiling to prevent the sugar mixture from burning.
- Don’t overcook the mixture, or the finished fudge can become dry and crumbly.
- Let the fudge cool completely before cutting.
- For clean slices, use a sharp knife and wipe it clean between cuts.
Easy Variations
Peanut Butter Chocolate Swirl
Reserve a little melted chocolate and swirl it over the top before the fudge sets.
Crunchy Peanut Butter Fudge
Use crunchy peanut butter or add chopped roasted peanuts.
Extra Creamy Fudge
Add a small amount of heavy cream after removing the mixture from the heat for an even softer texture.
Storage
Store the fudge in an airtight container at room temperature for several days. For longer storage, refrigerate it in a sealed container.
You can also freeze properly wrapped fudge for longer-term storage. Thaw it in the refrigerator before serving.
