Ingredients Notes
To make the best Peanut Butter Fudge, you’ll need:
- Peanut Butter – Use creamy peanut butter for a smooth texture. Avoid natural peanut butter, as the oil separation may affect consistency.
- Butter – Unsalted butter adds richness and enhances the flavor.
- Powdered Sugar – Helps achieve the perfect fudge texture.
- Milk or Heavy Cream – Adds moisture and a creamy consistency.
- Vanilla Extract – Enhances the flavor with a warm, sweet note.
- Salt (Optional) – A pinch of salt balances the sweetness and intensifies the peanut butter flavor.

How to Make Peanut Butter Fudge
Step 1: Prepare the Pan
- Line an 8×8-inch baking dish with parchment paper for easy removal.
- Lightly grease the parchment paper to prevent sticking.
Step 2: Melt Butter and Peanut Butter
- In a medium saucepan, melt the butter and peanut butter over low heat.
- Stir continuously until smooth and well combined.
Step 3: Mix in Sugar and Milk
- Remove from heat and stir in powdered sugar, milk, vanilla extract, and a pinch of salt.
- Mix thoroughly until the fudge is thick and smooth.
Step 4: Pour and Set
- Transfer the mixture into the prepared pan.
- Spread evenly with a spatula.
- Let it cool at room temperature for about an hour, then refrigerate for at least 2 hours.
Step 5: Slice and Serve
- Once firm, remove from the pan and cut into small squares.
- Serve immediately or store for later enjoyment.
Storage Options
Proper storage ensures that your peanut butter fudge stays fresh and delicious for as long as possible. If you plan to enjoy it within a few days, store the fudge in an airtight container at room temperature. This keeps the texture soft and chewy while preventing it from drying out. For longer storage, refrigerating the fudge is a great option. Simply place it in a sealed container, layering parchment paper between the pieces to prevent sticking. It will stay fresh for up to two weeks in the fridge.
For extended storage, freezing is the best option. Wrap each piece individually in plastic wrap or parchment paper before placing them in a freezer-safe container or ziplock bag. This extra layer helps prevent freezer burn and keeps the fudge from absorbing unwanted odors. When ready to enjoy, let the frozen fudge sit at room temperature for about 15-20 minutes to soften before serving. This way, you can always have a batch of peanut butter fudge ready for a sweet craving or unexpected guests!
Variations and Substitutions
Peanut butter fudge is incredibly versatile, allowing for a variety of flavor combinations and ingredient swaps. If you’re looking to customize your fudge, here are some delicious variations and substitutions to try:
- Chocolate Peanut Butter Fudge – Swirl in melted chocolate or mix in chocolate chips to create a rich, decadent twist on classic peanut butter fudge.

- Nut-Free Version – Swap peanut butter for sunflower seed butter or cookie butter to create a nut-free alternative while maintaining a creamy consistency.
- Dairy-Free Fudge – Use coconut milk and dairy-free butter substitutes to make a lactose-free version that’s just as creamy and satisfying.
- Salted Peanut Butter Fudge – Sprinkle flaky sea salt on top for a sweet-and-salty contrast that enhances the flavors.
- Spiced Fudge – Add a pinch of cinnamon or nutmeg for a warm, aromatic twist perfect for the holidays.

- Drizzle or Toppings – Drizzle melted white or dark chocolate over the fudge, or sprinkle chopped nuts, crushed pretzels, or shredded coconut for extra texture and flavor.
