These Easy Sugar-Free Keto Chocolate Peanut Butter Fudge Truffles are little bites so good you’ll never notice they are sugar-free!
Sugar Free Chocolate Peanut Butter Truffles
These Easy Sugar-Free Keto Chocolate Peanut Butter Truffles are one of those recipes that remind me why I started SugarFreeMom.com back in 2011 and why I’m still here.
They’re rich, chocolatey, indulgent, and taste like a classic peanut butter cup… yet they’re low carb, sugar-free, and made with simple ingredients you can pronounce. No powdered sugar, no added sugars, and no blood sugar rollercoaster afterward.
This recipe was originally written in 2013, long before I went back to nutrition school, before “midlife macros” was even a phrase, and before sugar-free treats were widely available.
Looking back now, I’m proud of how intuitive this recipe was and with a few thoughtful updates, it fits beautifully into how I eat and teach today.
Whether you’re making these for special occasions, the holidays, Valentine’s Day, or just because your sweet tooth is calling, these truffles deliver a perfect blend of indulgence and intention. Recipe instructions have been updated for an easier method then double boiler and new pictures have been added as well.
Why These Sugar-Free Chocolate Peanut Butter Truffles Still Work
There’s a reason peanut butter and chocolate are a timeless combination. The nutty flavor of peanut butter paired with rich chocolate creates a truly indulgent experience — and when done right, you don’t need sugar to make it delicious.
These truffles offer:
- A guilt-free treat for anyone reducing sugar intake
- A low carb dessert option that still feels satisfying
- A healthier format than traditional fudge or candy
- Flexibility for a variety of dietary needs
They’re soft, creamy, melt-in-your-mouth bites with that classic love affair of peanut butter and chocolate without the excess consumption that often comes with sugar-laden candy.
The Inspiration Behind the Recipe
This recipe is inspired by my grandma’s old-fashioned fudge buttons-the kind made with butter, cocoa, powdered sugar, milk, and peanut butter. I loved those flavors growing up, but I wanted to recreate them in a way that aligned with a sugar free, low carb lifestyle.
After one unsuccessful attempt (and a kitchen mess), the second and third versions were perfected. All thanks to my grandma and a little kitchen persistence.
The result? A sugar-free chocolate peanut butter fudge truffle that delivers the same nostalgic flavor, just without the added sugars.
My boys who have peanut and tree nut allergies were especially happy when they were able to eat these yummy chocolate bites since I used sunbutter the second time I made them. Hubby and daughter enjoyed the first batch using peanut butter. I like both!
Ingredient Breakdown (And Why They Matter)
Sugar-Free Chocolate Chips
I recommend premium sugar-free chocolate chips sweetened with stevia or monk fruit. They melt beautifully, taste like real chocolate, and don’t contain added sugars.
Look for options made with:
- Cocoa butter
- Chocolate liquor
- No maltitol (to avoid digestive upset and laxative effect)
Tip: Always check labels — some “sugar-free chocolate” products still include hidden sugars or sugar alcohols that can spike blood sugar.
Peanut Butter (or SunButter)
Use real peanut butter with just peanuts and salt for the best flavor and texture. This creates the perfect balance of smooth peanut butter and chocolate.
Nut-free option:
- Swap peanut butter for sunflower seed butter to accommodate peanut or tree nut allergies.
Butter
Butter adds richness and helps create that classic fudge-like texture.
Dairy-free swaps:
- Coconut oil
- Dairy-free butter
Both options still provide a creamy mouthfeel and delicious flavor.
Milk
A small amount of milk softens the truffle mixture and makes it scoopable.
Dairy-free milk swaps:
- Unsweetened almond milk
- Unsweetened coconut milk (carton, not canned)
- Unsweetened macadamia milk
Stevia or Monk Fruit
A few droppers of chocolate-flavored monk fruit or chocolate stevia enhance sweetness without overpowering the chocolate.
Start small — you can always add more, but you can’t take it out.
Coconut Oil (Chocolate Coating)
Coconut oil helps thin the melted chocolate for dipping and creates a smooth, glossy coating that sets beautifully when chilled.
Optional Swap: Using Sugar-Free Peanut Butter Powder Instead of Natural Peanut Butter
I often get asked if these truffles can be made with sugar-free peanut butter powder instead of natural peanut butter, especially by women following midlife macros who want to lower fat slightly.
The short answer is yes, but it does require a small adjustment so the truffles still hold their shape.
Why the Swap Isn’t 1:1
Natural peanut butter works in this recipe because it provides:
- Fat (structure)
- Thickness (body)
- Creamy texture
Peanut butter powder, on the other hand, is mostly defatted peanut solids, so if you swap it straight across without adjustments, the mixture will be:
- Too dry
- Crumbly
- Unable to hold its shape once chilled
How to Successfully Use Peanut Butter Powder
If replacing 1/2 cup natural peanut butter, here’s what to do:
Use:
- 1/2 cup sugar-free peanut butter powder
- PLUS 1/4 cup liquid total
Best liquid options (choose one):
- Unsweetened almond milk
- Unsweetened coconut milk (carton)
- Dairy milk if tolerated
Add Back Some Fat for Structure
To replace the fat lost from removing natural peanut butter, you’ll also need:
- 2 additional tablespoons butter (or dairy-free butter)
This restores enough fat so the truffles:
- Set properly
- Hold their shape
- Stay creamy instead of chalky
How to Mix It In
- Melt the butter and chocolate chips first.
- Whisk peanut butter powder with the milk until thick and smooth.
- Stir the peanut butter mixture into the melted chocolate.
- Proceed with chilling and shaping as written.
Texture Expectation
- Slightly firmer than the original version
- Less oily mouthfeel
- Still rich and chocolate-forward
This version is a great option if you’re aiming for a lower-fat, still-satisfying treat — especially for midlife weight loss phases where fat tolerance can be lower.
Tip: If the mixture feels too soft after chilling, refrigerate an additional 10–15 minutes before rolling.
How These Fit Into a Low Carb or Keto Lifestyle
These truffles are not an everyday treat — and that’s intentional.
They’re designed for:
- Special occasions
- Holidays
- Dessert when you want something truly satisfying
Because they’re rich and flavorful, one truffle goes a long way. That’s the joy of guilt-free indulgence done right — quality ingredients, mindful portions, and no added sugars.
Stored properly in an airtight container in the refrigerator, they hold their shape and texture perfectly.
Storage Tips
- Keep refrigerated until ready to serve
- Store in an airtight container
- Best enjoyed chilled or slightly softened at room temperature
Because these are made with melted chocolate and natural fats, they will soften if left out too long at room temperature.
These Sugar-Free Chocolate Peanut Butter Truffles are proof that you don’t need powdered sugar, added sugars, or artificial ingredients to create a truly delectable treat.
They honor the classic taste of peanut butter cups while offering a healthier, low carb format that supports mindful indulgence -especially when you want something special without derailing your goals.
Make a batch, store them in the fridge, and enjoy the joy of guilt-free indulgence — one truffle at a time.
