What Ingredients You Will Need

This old fashioned peanut butter fudge recipe relies on a handful of pantry staples that come together to create that perfect texture and flavor. Here’s what you’ll need:

• Granulated Sugar (2 cups, about 400g) — The sweetness backbone; I prefer regular white sugar for that classic fudge taste.
• Evaporated Milk (3/4 cup, 180ml) — Adds creaminess without making the fudge too runny.
• Unsalted Butter (1/2 cup, 115g) — Softened; brings richness and helps the fudge set beautifully.
• Creamy Peanut Butter (1 cup, 250g) — I usually use a natural brand with no added sugar for a pure peanut flavor, but you can go for classic creamy if you like it sweeter.
• Vanilla Extract (1 teaspoon) — Just a splash to round out the flavors.
• Salt (a pinch) — Enhances the peanut butter’s nuttiness and balances the sweetness.

If you want to experiment, you could swap in natural peanut butter or even try almond butter for a twist. Just keep in mind that natural types can sometimes make the fudge a bit softer. For those watching gluten, this recipe is naturally gluten-free, which is a nice bonus.

Equipment Needed

• Medium-sized heavy-bottom saucepan: Perfect for melting sugar and butter evenly without scorching.
• Wooden spoon or heatproof spatula: For stirring the fudge mixture smoothly.
• 9×9-inch square baking pan: I line mine with parchment paper for easy removal.
• Measuring cups and spoons: To keep the ingredient ratios spot-on.
• Candy thermometer (optional): If you want to be precise, but I’ve had great results without one.

If you don’t have a square pan, a loaf pan works well too — just adjust the thickness accordingly. Also, if you’re on a budget, a simple non-stick pan and a silicone spatula do the trick just fine. Keeping your tools clean and dry helps the fudge set better, so I always give everything a quick wipe before getting started.

Detailed Preparation Method

1. Prepare your pan: Line a 9×9-inch (23×23 cm) baking pan with parchment paper, letting a bit hang over the sides for easy fudge removal. Set aside.
2. Combine sugar and evaporated milk: In your heavy-bottom saucepan, add 2 cups (400g) granulated sugar and 3/4 cup (180ml) evaporated milk. Stir gently to combine before placing on medium heat.
3. Bring to a boil: Cook the mixture over medium heat, stirring constantly to prevent burning. Once it reaches a steady boil, keep stirring and boil for about 4-5 minutes. (If you have a candy thermometer, aim for 234°F to 240°F / 112°C to 115°C.) Be patient — this step is key to the fudge’s texture.
4. Remove from heat and add butter and peanut butter: Quickly stir in 1/2 cup (115g) softened unsalted butter and 1 cup (250g) creamy peanut butter. Stir vigorously until fully melted and smooth. This is when the magic happens — the mixture will thicken and become glossy.
5. Finish with vanilla and salt: Add 1 teaspoon vanilla extract and a pinch of salt. Give it one last good stir, then pour the fudge into your prepared pan, smoothing the top with a spatula.
6. Let it set: Allow the fudge to cool at room temperature for at least 2 hours, or until firm. For quicker setting, pop it in the fridge after about 30 minutes.
7. Slice and serve: Use the parchment paper edges to lift the fudge out of the pan. Cut into 1-inch (2.5 cm) squares and enjoy!

Pro tip: Stir gently but persistently during boiling to avoid grainy sugar crystals. Also, don’t rush the cooling — letting the fudge set fully means that perfect melt-in-your-mouth bite.

Cooking Tips & Techniques

From my experience, the biggest trick with old fashioned peanut butter fudge is controlling the sugar’s temperature and texture. Here are some tips I’ve learned the hard way:

• Use a heavy-bottomed pan: It distributes heat evenly and helps prevent hot spots that can burn the sugar.
• Constant stirring: Keeps the sugar from settling and burning. It’s tempting to walk away, but trust me, don’t.
• Watch your boil time: Too short and the fudge won’t set; too long and it gets hard as a rock. Aim for that soft ball stage (234-240°F / 112-115°C).
• Butter at room temperature: Cold butter will seize up the mixture, making it lumpy.
• Don’t skip the parchment paper: It makes cleanup easier and helps you lift the fudge out without breaking.
• Room temperature cooling: Let it cool undisturbed for best results. Refrigeration can speed up setting but sometimes dulls the flavor a bit.

I once rushed the cooling step and ended up with fudge that crumbled — lesson learned! Taking that extra time is worth it every time.

Variations & Adaptations

While the classic old fashioned peanut butter fudge is hard to beat, I’ve tried a few spins that add fun twists:

• Chocolate Peanut Butter Fudge: Swirl in 1/2 cup (90g) melted semi-sweet chocolate after adding the peanut butter for a marbled effect.
• Chunky Peanut Butter Fudge: Stir in 1/4 cup (30g) chopped roasted peanuts for extra crunch and texture.
• Low-Sugar Version: Replace granulated sugar with a sugar substitute suitable for baking, like erythritol, and use natural peanut butter with no added sugar.
• Vegan Adaptation: Use coconut cream instead of evaporated milk, vegan butter, and a plant-based peanut butter. Keep an eye on texture as it may vary slightly.
• Flavored Fudge: Add a teaspoon of cinnamon or a splash of bourbon for a grown-up twist that surprises and delights.

One of my favorite personal tweaks is adding a pinch of sea salt flakes on top right before setting — it cuts through the sweetness perfectly and makes every bite pop.

Serving & Storage Suggestions

Old fashioned peanut butter fudge is best served at room temperature when its texture is creamy and soft. For a nice presentation, cut it into neat squares and arrange on a pretty plate or wrap in wax paper for gifting.

This fudge pairs wonderfully with a hot cup of coffee or a cold glass of milk — honestly, it’s a match made in heaven. For parties, consider serving alongside fresh fruit or simple cookies to balance the richness.

To store, keep the fudge in an airtight container at room temperature for up to one week. If your kitchen is warm, pop it in the fridge to prevent it from getting too soft. Frozen fudge also freezes well — just wrap tightly and thaw in the fridge overnight before serving.

One neat thing I’ve noticed is that the flavor actually deepens if you let the fudge rest for a day or two, so if you can wait, that’s a bonus!

Nutritional Information & Benefits

A typical serving (1 square, about 30g) of this old fashioned peanut butter fudge packs roughly 150-180 calories, mostly from fats and sugars. It’s a sweet treat, so moderation is key.

That said, peanut butter offers protein and healthy fats, making this fudge a slightly more satisfying indulgence than plain sugar candy. The use of evaporated milk adds calcium and some B vitamins as well.

This recipe is naturally gluten-free and can be adapted for dairy-free diets with substitutions. Just watch for potential peanut allergies, as this is obviously peanut-heavy.

From my perspective, enjoying a piece of this fudge every now and then is a lovely way to savor a sweet moment without guilt — just pair it with balanced meals and some fresh fruit during the day.

Frequently Asked Questions

Can I use crunchy peanut butter instead of creamy?

Absolutely! Crunchy peanut butter will add a bit of texture to the fudge, making it more interesting. Just keep in mind the fudge might be a bit less smooth.

Grainy fudge usually means the sugar crystallized during cooking. Make sure to stir constantly and don’t over-boil. Using a candy thermometer helps prevent this issue.

How long does homemade peanut butter fudge last?

Stored in an airtight container, fudge stays fresh at room temperature for about one week. Refrigeration can extend it to two weeks, and it freezes well up to three months.

Can I double the recipe?

Yes, doubling is fine but use a larger pan to keep the fudge thickness consistent. Also, be mindful of cooking times, as larger batches may take a little longer to reach the right temperature.

Is there a way to make this fudge less sweet?

You can reduce the sugar slightly or use natural peanut butter with no added sugar to balance the sweetness. Adding a pinch of salt on top also helps cut through the sugary taste.
