Keto Fudge
This post may contain affiliate links. See my disclosure policy.
My keto fudge is so smooth, rich, and creamy, you won’t believe it is low-carb! Made with just 2 ingredients, it’s an instant chocolate fix. 2 grams of net carbs per serving.
This keto fudge recipe comes together with little prep time and makes for the perfect low-carb, creamy, and rich chocolate treat. Inspired by my 2-ingredient peanut butter fudge, I skipped the layering process and mixed everything instead.
I tested this method several times to make sure the fudge would hold its shape without relying on keto condensed milk or butter. One of the first things I learned in culinary school was that traditional fudge relies on sugar and fat for its structure, so achieving the same thick and creamy texture with nut butter and keto chocolate chips took some trial and error. The result? A foolproof keto chocolate fudge that’s smooth, indulgent, and ready in 5 minutes.

Why I love this recipe
- Full of flavor. This fudge is proof that keto desserts can taste just as good (if not better) than traditional fudge.
- Diet-friendly. Made without heavy cream or sugar, it’s gluten-free and keto-friendly.
- Quick and easy. There’s no baking required, and it comes together in under 5 minutes- mix, chill, and slice.
- Always a crowd pleaser. I’ve made this fudge for friends and family more times than I can count, and no one has ever guessed it was keto until I told them.

Key Ingredients

- Peanut butter. Smooth and drippy with no sugar added. If you’re not a fan of peanut butter, I’ve also made this recipe with cashew butter and almond butter, and it’s just as fabulous.
- Keto chocolate OR chocolate chips. I used homemade sugar-free chocolate chips, but store-bought chocolate chips or a chopped-up unsweetened chocolate bar can also work.
Tested recipe variations
- Nut-free fudge. Swap the peanut butter for tahini or sunflower seed butter for a nut-free option (I’ve tested both- tahini gives a slightly earthy flavor, while sunflower butter is closer to classic peanut butter).
- Mix-ins. Fold in chopped pecans, walnuts, shredded coconut, or extra chocolate chips.
- Cream cheese fudge. When I want to make REALLY decadent fudge, I’ll swap the peanut butter for softened, full-fat cream cheese. Try it and thank me later!
- Swap the chocolate. Use sugar-free white chocolate chips or dark chocolate chips instead.
How to make keto fudge
Step 1- Combine. In a microwave-safe bowl or on the stovetop, combine the chocolate chips and peanut butter.
Step 2- Melt. Heat until melted, then stir to ensure the mixture is fully combined.
Step 3- Pour and chill. Pour the fudge batter into the prepared pan and refrigerate or freeze it until firm.
Step 4- Slice. Once the fudge has set, remove it from the pan and slice it into pieces using a sharp knife.
Pro recipe tips
- Use a warm knife. When it comes time to slice, run your knife under hot water, wipe it dry, and slice quickly. I learned this trick in culinary school, and it’s the easiest way to clean, professional-looking edges without dragging.
- Thicken the fudge. Depending on the brand of peanut butter, the batter can sometimes be thinner in consistency. If this happens, add 1-2 tablespoons of keto powdered sugar or almond flour to thicken the mixture. I tested this a few times, and it prevented the fudge from setting too soft.
- Enhance the flavor. Stir in one teaspoon of vanilla extract for depth, or finish with a sprinkle of flaky salt or a dusting of cocoa powder to make it look a little fancier (I do this for gift-giving).
Frequently asked questions
Because fudge is quite delicate, it should always be stored in the refrigerator in a sealed container. Properly stored, it will stay fresh for up to 1 month.
Yes! Place the fudge in a shallow, airtight container or freezer-safe bag. It freezes well for up to 6 months, and you can thaw pieces in the fridge overnight.
Let the fudge set completely, then slice it into neat squares. Wrap each piece in parchment paper or place squares in mini candy cups, then store in a decorative tin or box. I’ve done this many times around the holidays- it keeps the fudge fresh, prevents sticking, and makes for a professional-looking homemade gift.
