Why This Recipe Works
- Flavor-Packed: Intense Dutch cocoa and creamy peanut butter create a fudgy powerhouse of flavor.
- Easy Steps: No flour, no fuss – just mix, drop, and bake.
- Reliable Results: Perfectly soft and chewy cookies every single time.
- Flexible: Swap nut butters or sweeteners to suit your tastes and diet.
Ingredients You’ll Crave

- ⅔ cup powdered sugar-free sweetener (127g): Keeps these cookies keto-friendly and sweetens without a sugar crash.
- ⅓ cup Dutch cocoa powder (27g): For that dark, rich chocolate fudge taste.
- ½ tsp baking soda (3g): Helps the cookies puff just right.
- ¼ tsp salt (1.5g): Balances the sweetness and deepens flavors.
- ½ cup unsweetened creamy peanut butter (128g): Or your favorite nut/seed butter – it adds creaminess and healthy fats.
- 2 large eggs: Bind all the luscious ingredients together and add moisture.
- ¼ cup sugar-free chocolate chips (56g): Bursts of melty chocolate pepper every bite.
If you want to personalize your batch, try almond butter for a milder nutty note, or sunflower seed butter for a nut-free version. Make sure to use a powdered sugar substitute that measures cup-for-cup if you want perfect sweetness and texture — I love erythritol-based blends for this.
Gear Up Before Cooking
Having the right tools makes baking this Keto Flourless Fudge Cookies Recipe smooth and stress-free. A well-lined baking sheet and a reliable mixing bowl will be your best allies here.
Tools You’ll Need
- Baking Sheet: Standard 9×13 inch or larger, lined with parchment paper for easy cleanup and cookie release.
- Mixing Bowls: One medium-sized for combining dry ingredients and another for wet if you prefer, though this recipe is simple enough to mix in one bowl.
- Spoon or Cookie Scoop: To portion dough evenly and keep those cookies uniform.
- Measuring Cups and Spoons: Precision is key for keto-friendly baking.
- Optional: Damp fingers or a small spatula to shape dough balls smoothly.
Step-by-Step to Keto Flourless Fudge Cookies Recipe Bliss
You’ll be amazed how quickly these cookies come together — they require minimal fuss but deliver maximum wow. Let’s go!
- Preheat your oven to 350°F (175°C). Line a cookie sheet with parchment paper so these beauties don’t stick and come out clean every time.
- Mix dry ingredients: In a medium bowl, whisk powdered sugar-free sweetener, Dutch cocoa powder, baking soda, and salt until evenly combined and velvety smooth.
- Add the wet players: Stir in peanut butter and the eggs, mixing vigorously until you get a smooth, sticky dough that holds together like chocolate silk.
- Fold in those chocolate chips: Release bursts of melty sweetness with every bite.
- Shape the cookies: Using a spoon, scoop out roughly 1-inch balls and place them 3 inches apart on your lined baking sheet. Use damp fingers to gently smooth and flatten each one — don’t worry about perfect shapes; rustic is delicious.
- Bake for 7-8 minutes: The edges will look set but the centers might be slightly soft. That’s exactly how you want them. They’ll firm up perfectly as they cool off the heat.
- Cool and enjoy: Let your cookies rest on the sheet for at least 10 minutes before transferring to a wire rack or plate to cool completely. Then dig in—these are best enjoyed fresh but hold up well for days!
Pro Tips for Success
Watch those bake times carefully — these cookies go from perfectly fudgy to dry in moments. If your oven runs hot, pull them at 7 minutes. Use damp fingers to flatten dough for a nice even texture, and always cool on the sheet first to finish setting — patience pays off big here.
Flavor Variations for Keto Flourless Fudge Cookies Recipe

- Mint-Chocolate: Add ½ tsp peppermint extract to the dough for a refreshing twist.
- Spicy Kick: Mix in a pinch of cinnamon and cayenne for a chili-chocolate surprise.
- Nutty Delight: Fold in chopped pecans or walnuts for added crunch and depth.
- Berry Bliss: Stir in freeze-dried raspberries for tangy bursts against rich fudge.
- Mocha Madness: Add 1 tsp instant espresso powder to the dry mix for a coffee-infused edge.
- Seed Butter Swap: Use sunflower or tahini for a unique flavor profile that’s nut-free.
Make-Ahead, Storage & Freezing
- Refrigerate: Store baked cookies in an airtight container in the fridge for up to 5 days and enjoy chilled or at room temp.
- Freeze: Flash freeze shaped dough balls on a tray for 1 hour, then transfer to a freezer-safe bag. Bake frozen dough balls adding 2-3 minutes to bake time.
- Reheat: Warm cookies for 10 seconds in the microwave for that fresh-out-of-the-oven softness.
- Make Ahead: Prepare dough up to 24 hours in advance and keep it chilled, shaping just before baking.
Keto Flourless Fudge Cookies Recipe FAQs

- Why do the cookies seem soft when baked? They’ll firm up as they cool—don’t overbake or you’ll lose that fudgy center.
- Can I substitute the peanut butter? Absolutely! Use any creamy nut or seed butter you love for different flavor profiles.
- Are sugar-free sweeteners interchangeable? Most erythritol-based sweeteners substitute cup-for-cup, but avoid liquid sweeteners for this recipe.
