Step‑by‑Step Instructions for Keto Flourless Fudge Cookies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven heats up, line a baking sheet with parchment paper to prevent the cookies from sticking. This will help your Keto Flourless Fudge Cookies achieve that perfect, gooey texture and make clean-up a breeze.
Step 2: Mix Dry Ingredients
In a medium-sized mixing bowl, combine the powdered sugar-free sweetener, Dutch cocoa powder, baking soda, and salt. Whisk these dry ingredients together until they are fully blended, ensuring there are no clumps. This step sets the foundation for the rich chocolate flavor in your Keto Flourless Fudge Cookies!
Step 3: Combine Wet Ingredients
Add the creamy peanut butter and two large eggs to the bowl with your dry mixture. Using a spatula or wooden spoon, stir the ingredients together until a sticky dough forms. The combination of peanut butter and eggs binds everything together and contributes to the fudgy texture of your cookies.
Step 4: Incorporate Chocolate Chips
Gently fold the sugar-free chocolate chips into your cookie dough until they are evenly distributed. This step is crucial for ensuring every bite of your Keto Flourless Fudge Cookies has delightful pockets of melted chocolate, enhancing the overall rich experience of this indulgent treat.
Step 5: Shape Cookies
Using a tablespoon, scoop out portions of the dough and drop them onto the prepared baking sheet, leaving space between each ball to allow for spreading. Gently flatten each cookie slightly with damp fingers to encourage even baking. This will help achieve the desired crackly top that makes these cookies so enticing.
Step 6: Bake the Cookies
Slide the baking sheet into your preheated oven and bake the cookies for 7 to 8 minutes. Keep a close eye on them; look for the edges to be set while the centers remain soft. Avoid overbaking, as the residual heat will firm them up as they cool, ensuring a perfect gooey texture in your Keto Flourless Fudge Cookies.
Step 7: Cool the Cookies
Once baked, remove the cookies from the oven and allow them to cool on the baking sheet for a few minutes. This cooling period helps them set properly. Afterward, gently transfer the cookies to a wire rack to cool completely. This final step ensures the cookies maintain their soft centers and rich flavors.

Keto Flourless Fudge Cookies Recipe FAQs
What type of sweetener should I use?
Absolutely! For these keto-friendly cookies, I recommend using a powdered sugar-free sweetener like erythritol or a monk fruit-erythritol blend. Powdered versions provide a smoother texture, while granulated sweeteners might cause a gritty bite.
How do I store leftover cookies?
Very! You can cover and store leftover Keto Flourless Fudge Cookies at room temperature for up to 1 day to keep them soft. If you need to store them longer, an airtight container in the fridge will keep them fresh for up to 5 days!
Can I freeze Keto Flourless Fudge Cookies?
Certainly! To freeze, line the cookies on a baking sheet and place them in the freezer for 1-2 hours until solid. Then, transfer them to a freezer-safe bag or container. These cookies will last up to 2 months frozen. When you’re ready to enjoy, just thaw in the fridge overnight and warm them in the microwave for about 10-15 seconds.
What should I do if my dough is too sticky?
If your dough turns out too sticky, don’t worry! This might happen due to variations in peanut butter consistency. Try chilling the dough in the fridge for about 30 minutes; this will help firm it up and make it easier to shape. If you prefer, you can also sprinkle a bit of cocoa powder over it to help with stickiness.
Are these cookies safe for those with nut allergies?
For sure! You can easily make these cookies nut-free by substituting the unsweetened creamy peanut butter with sunflower seed butter or another allergy-friendly alternative. Just ensure that whatever nut or seed butter you use is unsweetened for the best results.
How should I know when to take the cookies out of the oven?
Great question! You want to look for cookies that have firm edges while the centers remain soft and slightly underbaked. This usually takes about 7-8 minutes at 350°F (175°C). Remember, they’ll continue to firm up as they cool, giving you that delicious gooey center you crave!
