What You’ll Need

1 cup creamy peanut butter
½ cup coconut oil
¼ cup maple syrup
1 teaspoon vanilla extract
1 ½ cups powdered sugar
¼ teaspoon salt

Tools Required

Medium saucepan
Mixing bowl
Whisk or silicone spatula
Measuring cups and spoons
8×8 baking dish
Parchment paper
Knife

Recipe Instructions

Step 1: Melt the Peanut Butter and Coconut Oil

Add 1 cup creamy peanut butter and ½ cup coconut oil to a medium saucepan.

Heat over low heat, stirring slowly until the coconut oil melts completely and the mixture becomes smooth and glossy.

Do not let it boil. Just warm it enough so everything melts together.

Step 2: Add Maple Syrup, Vanilla, and Salt

Remove the saucepan from heat.

Stir in:

¼ cup maple syrup
1 teaspoon vanilla extract
¼ teaspoon salt

Whisk until the mixture becomes silky and fully blended.

Step 3: Mix in the Powdered Sugar

Transfer the warm mixture to a mixing bowl.

Add 1½ cups powdered sugar, a little at a time, stirring after each addition.

The mixture will become thicker and start to look like soft peanut butter frosting.

Keep mixing until smooth with no dry spots.

Step 4: Press Into the Pan

Line an 8×8 baking dish with parchment paper.

Pour the thick peanut butter fudge mixture into the pan and spread evenly with a spatula.

Smooth the top so it’s flat.

Step 5: Chill Until Firm

Place the dish in the refrigerator for about 2 hours, or until the fudge is fully firm.

Once set, lift the parchment paper out and cut into 16 squares.

Pro Tips

Use creamy peanut butter for the smoothest texture. Natural peanut butter can separate and affect the consistency.
If your mixture looks too thick, warm it slightly before adding more powdered sugar.
Press parchment paper into the pan first so the fudge lifts out easily.
Chill the fudge fully before cutting for clean squares.
Use a sharp knife and wipe it between cuts for perfect edges.

Substitutions and Variations

Swap peanut butter with almond butter or cashew butter
Add ¼ cup mini vegan chocolate chips
Sprinkle flaky sea salt on top
Stir in 2 tablespoons cocoa powder for chocolate peanut butter fudge

Make Ahead Tips

Why This Recipe Works (Quick Science)

This fudge works because of the balance between fat and sugar.

Coconut oil solidifies when chilled. That helps the fudge firm up without needing cooked sugar like traditional fudge.

Powdered sugar dissolves quickly and creates that smooth, creamy texture. Peanut butter adds both fat and protein, which makes the final texture rich and stable.

When everything chills together, the mixture sets into sliceable fudge.

Common Mistakes

Overheating the peanut butter

Too much heat can make the oils separate. Keep the heat low.

Adding powdered sugar too fast

Adding it slowly helps prevent lumps.

Not chilling long enough

The fudge needs at least 2 hours to fully set.

Using a very oily natural peanut butter

This can make the fudge too soft.

What to Serve With

This fudge pairs great with:

Hot coffee
Almond milk or oat milk
Fresh strawberries
Banana slices
Dark chocolate drizzle

It’s also great on a dessert board with cookies and fruit.

Leftovers and Storage

Store fudge in an airtight container in the refrigerator.

Fridge: up to 1 week
Freezer: up to 2 months

If frozen, thaw in the fridge for about 30 minutes before eating.

FAQ

Can I make this without coconut oil?
Coconut oil helps the fudge firm up. Without it, the texture may stay soft.

Is natural peanut butter okay?
Yes, but stir it very well first. Thick natural peanut butter works best.

Can I make this less sweet?
You can reduce powdered sugar slightly, but the fudge may be softer.

Can I double the recipe?
Yes. Use a 9×13 pan instead of an 8×8.
