Ingredients

2 cups granulated sugar
½ cup milk (whole or 2% recommended for best texture)
1 cup creamy peanut butter
3 tablespoons unsalted butter
1 teaspoon vanilla extract

Step-by-Step Instructions

Prepare your pan: Lightly grease an 8×8-inch baking pan with butter or non-stick spray and set it aside. This will make removing the fudge easier once it has set.
Combine sugar and milk: Pour 2 cups of sugar and ½ cup of milk into a heavy saucepan. Place the pan over medium heat.
Boil the mixture: Stir the sugar and milk constantly until the sugar dissolves and the mixture comes to a full rolling boil. Continue boiling for exactly 3 minutes, maintaining a steady boil and stirring constantly to prevent anything from burning.
Remove from heat: Immediately take the saucepan off the heat after 3 minutes of boiling.
Add remaining ingredients: Quickly stir in 1 cup of creamy peanut butter, 3 tablespoons of butter, and 1 teaspoon of vanilla extract. Stir vigorously until the mixture becomes smooth and begins to thicken. This helps develop the perfect fudge texture.
Pour and spread: Quickly pour the fudge mixture into the greased pan. Use a spatula to spread it evenly.
Cool and set: Allow the fudge to cool at room temperature for 1 to 2 hours or until fully set and firm to the touch. Avoid refrigerating as this can affect texture.
Cut and serve: Once set, cut the fudge into small squares and serve. Enjoy your delicious homemade old-fashioned peanut butter fudge!

Pro Tips for Perfect Old-Fashioned Peanut Butter Fudge

Use creamy peanut butter: Choose smooth peanut butter for a classic, silky texture. Chunky versions can make the fudge grainy.
Measure ingredients accurately: Precise measurements prevent the fudge from becoming too soft or too hard.
Don’t skip stirring: Constant stirring while boiling prevents burning and ensures smooth caramelization.
Work quickly after cooking: The fudge mixture starts setting fast once off the heat, so pour it immediately into your pan and spread it evenly.
Let it set at room temperature: Cooling naturally produces a creamier texture. Refrigeration can cause the fudge to become too firm or develop condensation.

Variations and Substitutions

You can easily tweak this classic peanut butter fudge to suit your tastes or dietary preferences.

Healthier swaps: Use natural peanut butter (no sugar added) and swap white sugar for a more natural sweetener like coconut sugar for a slightly healthier option. However, texture and sweetness may vary.
Dairy-free option: Substitute regular milk with almond milk, oat milk, or another plant-based milk and use vegan butter instead of traditional butter.
Add mix-ins: Stir in chopped nuts, mini chocolate chips, or a sprinkle of sea salt on top for added texture and flavor.
Flavor boost: Add a teaspoon of cinnamon or a pinch of cayenne pepper for a subtle twist that complements the peanut butter beautifully.

Storage and Reheating Tips

Store your peanut butter fudge in an airtight container at room temperature. It will stay fresh for about 1 week. For longer storage, you can refrigerate it for up to 2 weeks; just let it come to room temperature before serving to soften the texture.

If you need to re-soften the fudge, warm it gently in short bursts in the microwave (5-10 seconds at a time) or let it sit at room temperature for a while. Avoid overheating as this can make the fudge oily or grainy.

Frequently Asked Questions

Can I use crunchy peanut butter instead of creamy?
Yes, you can, but creamy peanut butter provides a smoother fudge texture. Crunchy may result in a more textured, grainy fudge.
Do I have to use whole milk?
No, 2% milk works well too, but skim milk may affect the richness and texture of the fudge.
Why does my fudge turn out grainy?
Grainy fudge can result from undercooking, inaccurate measurements, or not stirring constantly during boiling. Make sure you maintain a steady boil for the full 3 minutes and stir vigorously after adding peanut butter.
Can I freeze this fudge?
Yes, fudge freezes well. Wrap it tightly in plastic wrap and store in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before serving.
Is there a vegetarian version of this recipe?
This recipe is naturally vegetarian and halal-friendly as it contains no meat or alcohol ingredients.
