Love keto desserts? Try keto chocolate mousse, keto peanut butter cookies, keto cheesecake, and keto brownies.

This sugar-free fudge recipe comes together with little prep time and makes for the perfect low-carb, creamy, rich chocolate fudge.

Inspired by my 2 ingredient peanut butter fudge, I skipped the layering process and instead mixed the two. The results speak for themselves: Thick, creamy fudge loaded with peanut butter flavor and gooey chocolate.

Why I love this recipe

• Full of flavor. This fudge is proof that low carb desserts can taste just as good (or better) than the real thing.
• Diet-friendly. Made with no heavy cream or sugar, it’s a vegan, gluten-free, and keto-friendly treat.
• It’s quick and easy. There’s no baking required, so you can have this fudge chilling in the fridge in less than 5 minutes.
• Everyone will love it. I can’t tell you how many times I’ve made this fudge recipe for my friends, and they’ve never been able to tell it’s sugar-free!

Ingredients needed

• 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-Iused homemade sugar-free chocolate chips, but store-bought chocolate chips or a chopped-up unsweetened chocolate bar can also work.

How to make keto fudge

I’ve includedstep-by-step photosbelow to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to therecipe cardat the bottom of this post.

Step 1- Prep work. Line a square pan or loaf pan with parchment paper.

Step 2- Melt. In a microwave-safe bowl or on the stovetop, combine the chocolate chips and peanut butter. 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.

Recipe tips and variations

• Make nut-free fudge. To make this fudge recipe suitable for nut allergies, use tahini or sunflower seed butter instead.
• Use a warm knife. When it comes time to slice the fudge, my #1 tip is to use a warm, slightly wet knife. Just run it under hot water, dry it, then slice and repeat.
• Experiment with mix-ins. Fold in chopped pecans, walnuts, shredded coconut, or extra chocolate chips.
• Enhance the flavor. Add 1 teaspoon of vanilla extract to the fudge batter, or garnish it with a sprinkle of sea salt and a dusting of unsweetened cocoa powder.
• Add cream cheese. 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.
• Thicken the fudge. Depending on the peanut butter I’m using, sometimes the fudge batter will be quite thin. If this happens, add 1-2 tablespoons of keto powdered sugar to thicken the batter.

Storage instructions

To store: As fudge is fragile, it should always be stored in the refrigerator, in a sealed container. The fudge will keep well for up to 1 month.

To freeze: Place the fudge in a shallow container and store it in the freezer for up to 6 months.
