Step‑by‑Step Instructions for Keto Flourless Fudge Cookies
Step 1: Preheat Your Oven
Begin by preheating your oven to 350°F (175°C). While the oven warms up, line a baking sheet with parchment paper to prevent sticking. This step is essential to ensure even baking and to achieve that delightful crackly crust that defines your Keto Flourless Fudge Cookies.
Step 2: Mix Dry Ingredients
In a large mixing bowl, whisk together the powdered sugar-free sweetener, Dutch cocoa powder, baking soda, and a pinch of salt. Mixing these dry ingredients thoroughly will ensure that the cookies have a uniform flavor and texture. Set this bowl aside while you prepare the wet ingredients for your rich, fudgy cookie dough.
Step 3: Combine Wet Ingredients
Add the creamy peanut butter and eggs to the bowl of dry ingredients. Stir well to combine until a sticky dough forms. The mixture should come together nicely, with a smooth texture that indicates you’ve achieved a perfect dough for your Keto Flourless Fudge Cookies. Don’t rush this step; thorough mixing ensures you capture all the delicious elements in each cookie.
Step 4: Incorporate Chocolate Chips
Gently fold in the sugar-free chocolate chips into your dough, ensuring they are evenly distributed. This will enhance every bite of your cookies with bursts of rich chocolate flavor. Be careful not to overmix, as you want to maintain the gooey texture that makes these Keto Flourless Fudge Cookies so delightful.
Step 5: Shape Cookies
Using your hands, form 1-inch balls from the dough and place them on the prepared baking sheet. Make sure to leave enough space between each cookie, as they will spread while baking. This step is important for achieving that beautiful crackly appearance. Allowing space between the cookies also ensures they cook evenly.
Step 6: Bake Cookies
Carefully transfer the baking sheet to the preheated oven and bake for 7-8 minutes. Watch closely! The cookies should look slightly underdone with a soft center. This doneness is key for the fudgy texture you are aiming for. Removing them from the oven at this point will ensure a perfectly gooey inside.
Step 7: Cool and Enjoy
Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely. This wait time is crucial, as it allows the cookies to set and achieve that perfect fudgy texture inside. Once cooled, savor the joy of your homemade Keto Flourless Fudge Cookies!

Expert Tips for Keto Flourless Fudge Cookies
-
Choose Your Sweetener: Opt for powdered sweetener like erythritol for a smoother dough; granulated can cause a grainy texture that’s less desirable.
-
Mixing Matters: Be gentle when combining ingredients. Overmixing can lead to dense cookies instead of the desired light, fudgy texture.
-
Monitor Baking Time: Keep an eye on your cookies towards the end of baking; they should appear slightly underdone to maintain that gooey center characteristic of Keto Flourless Fudge Cookies.
-
Cool Down Properly: Allow cookies to cool briefly on the baking sheet before transferring to a wire rack; this helps them set and achieve the perfect fudgy finish.
-
Experiment with Add-ins: Don’t hesitate to get creative! Adding in your favorite nuts or using different nut butters can change the flavor profile while keeping it keto-friendly.
How to Store and Freeze Keto Flourless Fudge Cookies
Fridge: Store in an airtight container for up to 3 days. This keeps your Keto Flourless Fudge Cookies soft and fresh, ensuring you get that delightful fudgy texture with every bite.
Freezer: For longer storage, freeze the cookies in a single layer on a baking sheet, then transfer to a zip-top bag or airtight container for up to 3 months. It’s the perfect way to save your treats for later!
Thawing: When ready to enjoy, simply thaw the Keto Flourless Fudge Cookies at room temperature for about 30 minutes, or microwave for 10-15 seconds for that just-baked warmth!
Reheating: If you want to enjoy them warm, pop the cookies in the microwave for about 10 seconds. This will bring back that soft, gooey center while maintaining the cookie’s delicious fudgy goodness.
Make Ahead Options
These Keto Flourless Fudge Cookies are perfect for meal prep enthusiasts! You can mix the dough and refrigerate it up to 24 hours in advance, allowing the flavors to meld beautifully. Simply form the cookie balls before refrigerating; this helps maintain their shape when baking. When you’re ready to bake, preheat your oven, place the dough balls on a baking sheet, and bake as directed—no need to thaw!
