Fold ½ cup of miniature chocolate chips into the fudge just before pouring into the pan.
- Salted Caramel Peanut Butter Fudge
Add ¼ cup of caramel sauce to the mixture along with the peanut butter. Sprinkle flaky sea salt on top before refrigerating.

Reduce peanut butter to ¾ cup and add ½ cup of melted white chocolate. Swirl with additional white chocolate on top.
- Keto / Low‑Carb Peanut Butter Fudge
Replace sugar with 1 cup of powdered erythritol or allulose. Use unsweetened peanut butter. The texture will be slightly softer.

Use plant‑based milk (coconut or oat milk) and vegan peanut butter. Omit the butter (not in this recipe – but if you add any, use vegan). Ensure sugar is vegan.
How to Store, Freeze, and Gift
Refrigerator
Store fudge in an airtight container in the refrigerator for up to 3 weeks. It stays firm and creamy.
Room Temperature
Fudge can sit at room temperature for a few hours, but it will soften. For gifting, keep it cool.
Freezer
Peanut butter fudge freezes beautifully. Wrap individual pieces in plastic wrap, then place in a freezer bag. Freeze for up to 3 months. Thaw in the refrigerator overnight.
Gifting Ideas
· Stack pieces in a festive tin lined with parchment.
· Place in cellophane bags tied with a ribbon.
· Layer between wax paper in a gift box.
Make Ahead
Make the fudge up to 2 weeks in advance and keep refrigerated. Cut just before serving.
Frequently Asked Questions (Peanut Butter Fudge)
Why is my fudge grainy?
Graininess comes from sugar crystallization. You may have stirred too vigorously after boiling, or the sugar did not dissolve completely before coming to a boil. Stir gently once the peanut butter is added.
Why is my fudge too soft?
You did not boil the sugar‑milk mixture long enough. Next time, boil for an extra minute. Also, make sure you refrigerate for at least 2 hours.
Can I use natural peanut butter?
It is not recommended. Natural peanut butter separates and can cause an oily, gritty texture. Stick with commercial creamy peanut butter.
Can I use brown sugar instead of white?
Yes, but the fudge will have a molasses flavor and be softer. Use light brown sugar and reduce the milk by 1 tablespoon.
How long does it take to set?
At least 2 hours in the refrigerator. For firmer fudge, chill for 4 hours or overnight.
Can I add marshmallows?
Yes. Fold in 1 cup of mini marshmallows after mixing in the peanut butter. They will melt slightly, creating a marshmallow swirl.
How many calories are in a piece?
A 1‑inch square has about 100‑120 calories, depending on the exact ingredients.
Can I make this in the microwave?
Yes. Combine sugar and milk in a microwave‑safe bowl. Microwave on high for 2 minutes, stir, then microwave for another 2 minutes until boiling. Add peanut butter and vanilla, stir, and pour into pan. Microwave power varies, so watch carefully.
