Rich and creamy keto peanut butter fudge offers all the indulgence of traditional fudge without the sugar spike. This small-batch recipe transforms simple ingredients into a velvety, satisfying treat that perfectly balances nutty depth with natural sweetness. Perfect for satisfying those dessert cravings while staying true to your keto goals.
Last week, I made this fudge for my keto-following sister, and she couldn't believe it was sugar-free. The creamy texture and rich peanut butter flavor had her convinced it was the real deal.
Essential Ingredients & Selection Tips
- Heavy Cream: Choose full-fat (36-40%) cream for the richest texture. Lower fat versions won't set properly
- Butter: Unsalted gives better control over final taste. Quality matters here - grass-fed adds extra richness
- Truvia® Sweet Complete™: Measures cup-for-cup like sugar, ensuring consistent results. Don't substitute with liquid sweeteners
- Natural Peanut Butter: Look for brands with only peanuts and salt. Check labels carefully for hidden sugars
- Optional: Vanilla Extract: A splash enhances the sweetness perception naturally
Detailed Step-by-Step Instructions
- Step 1: Create the Base
- Pour heavy cream into a heavy-bottomed saucepan. Add butter in small cubes for even melting. Measure Truvia® precisely - even small variations affect texture. Heat gradually over medium-low heat. Whisk continuously until butter melts completely.
- Step 2: Perfect the Condensed Mixture
- Increase heat to medium until mixture starts bubbling. Reduce heat immediately to maintain gentle simmer. Stir every 3-4 minutes to prevent scorching. Watch for mixture to reduce and thicken. Look for coating on back of spoon test.
- Step 3: Incorporate Peanut Butter
- Remove pan from heat completely. Add peanut butter in small portions. Whisk thoroughly between additions. Ensure completely smooth texture. Check for any unmixed portions.
- Step 4: Perfect Setting Technique
- Line loaf pan with parchment, leaving overhang. Pour mixture slowly to avoid air bubbles. Tap pan gently to release trapped air. Smooth top with offset spatula. Refrigerate minimum 2 hours until completely firm.

The first time I made this recipe, it revolutionized my keto dessert game. Coming from a family of traditional candy makers, I was skeptical about sugar-free fudge, but the texture and flavor won me over completely.
Achieving Perfect Texture
Learning to make this fudge taught me that patience is key. The condensing process can't be rushed - those 15-30 minutes of gentle simmering create the perfect base for silky-smooth results. When testing temperatures, I found that keeping the heat just below medium prevents any graininess.
Customization Options
After dozens of batches, I've discovered endless variations. Adding unsweetened cocoa powder creates a chocolate-peanut butter version, while stirring in chopped sugar-free chocolate adds delightful texture. Sometimes I sprinkle sea salt on top for a sophisticated flavor boost.
Troubleshooting Tips
If your fudge seems too soft, it likely needs more reduction time. Too firm? You might have reduced it slightly too long. The perfect consistency should be just firm enough to hold its shape while still being creamy when bitten into.
Storage Success
Through trial and error, I've found that layering pieces between parchment paper prevents sticking during storage. Keep in the refrigerator for that perfect fudgy texture, or freeze for a longer-lasting treat.

- → Can I use crunchy peanut butter?
- While possible, smooth peanut butter creates the best texture. If using crunchy, ensure it's well-stirred and keto-friendly.
- → How long will this fudge last?
- Stored in an airtight container, it lasts up to 2 weeks in the fridge or 3 months in the freezer.
- → Why is my fudge too soft?
