Ingredients You’ll Need
These ingredients are refreshingly straightforward but absolutely essential to achieving the perfect balance of flavor and texture in your cookies. Each component brings something special to the mix—whether it’s sweetness without the sugar, a luscious fudgy feel, or that classic chocolate aroma.
- Powdered sugar-free sweetener (127g): This keeps the cookies sweet while maintaining keto-friendly macros and ensures a smooth dough.
- Dutch cocoa powder (27g): Adds intense chocolate flavor and that rich, deep color that makes fudge cookies so irresistible.
- Baking soda (1/2 tsp): Helps the cookies rise slightly and gives them great texture without fluffiness.
- Salt (1/4 tsp): Balances the sweetness and enriches the chocolate flavor for a rounded taste experience.
- Unsweetened creamy peanut butter (128g): Provides a creamy base that binds everything together with a lovely nutty undertone; nut or seed butters work wonderfully too.
- Large eggs (2): Essential for binding and giving the cookies a soft, fudgy structure.
- Sugar-free chocolate chips (56g): These little morsels add surprise bursts of melty chocolate that elevate the cookie’s decadence.
How to Make Keto Flourless Fudge Cookies
Step 1: Prep Your Oven and Baking Sheet
Begin by preheating your oven to 350°F. Prepare a cookie sheet with parchment paper. This step is important to prevent sticking and ensure your cookies bake evenly.
Step 2: Mix Your Dry and Wet Ingredients
In a mixing bowl, combine the powdered sweetener, Dutch cocoa powder, baking soda, and salt—these dry ingredients form the chocolatey foundation. Then, add the creamy peanut butter and eggs. Stir everything together until you achieve a smooth and sticky dough; no flour needed! Once the dough is uniform, fold in the sugar-free chocolate chips to distribute those delightful melty pockets of goodness.
Step 3: Shape Your Cookies
Using a spoon, drop rough 1-inch balls of dough onto your lined cookie sheet, spacing them about 3 inches apart to allow for spreading. Then, dip your fingers in water to gently smooth and slightly flatten each dough ball—this helps achieve that classic fudge cookie shape.
Step 4: Bake to Perfection
Bake your cookies for 7 to 8 minutes. They might look a little underdone when you pull them from the oven, but resist the urge to bake longer—they’ll continue to firm up as they cool, resulting in that irresistible fudgy softness. Over-baking risks drying them out, so timing here is key.
Step 5: Cool and Enjoy
Allow your cookies to cool fully on the baking sheet or a wire rack. Once cooled, grab one (or two!) and savor the deeply chocolatey, fudgy experience you just created. Trust me, these cookies are incredibly addictive.
How to Serve Keto Flourless Fudge Cookies

Garnishes
To dress up your cookies, try sprinkling a pinch of sea salt on top right after baking for a wonderful sweet-salty contrast. A dusting of additional cocoa powder or a light drizzle of melted sugar-free chocolate also adds an elegant touch. For a festive flair, crushed nuts or toasted coconut flakes make excellent toppings.
Side Dishes
Pair these cookies with a creamy keto-friendly coffee or a chilled glass of unsweetened almond milk for a comforting combo. If you want to get fancy, a scoop of keto vanilla ice cream alongside transforms these cookies into a decadent dessert, perfect for impressing guests or just spoiling yourself.
Creative Ways to Present
Presenting these cookies in a rustic wooden box lined with parchment or stacking them as a small cake with layers of whipped cream and berries turns this simple treat into a conversation starter. You can even sandwich a keto frosting or nut butter between two cookies for an irresistible handheld delight.
Make Ahead and Storage
Storing Leftovers
Your Keto Flourless Fudge Cookies keep well at room temperature for several days if stored in an airtight container. This helps maintain their fudgy texture without drying out. For longer storage, refrigeration is great and can add a firmer bite depending on your preference.
Freezing
These cookies freeze beautifully. Just layer them between sheets of parchment paper inside a freezer-safe container or bag. When you want a treat, grab however many you like and let them thaw at room temperature, or warm slightly in a low-temperature oven for a freshly baked feel.
Reheating
If you prefer your cookies warm, pop them in the microwave for 10-15 seconds or in a 300°F oven for about 5 minutes. This revives that freshly baked softness and melts the chocolate chips to perfection without drying them out.
FAQs
Are these cookies truly flourless?
Yes! This recipe skips traditional flour entirely, relying on peanut butter and eggs to provide structure and moisture, making these perfect for gluten-free and keto diets.
Can I substitute the peanut butter?
Absolutely. You can use any creamy nut or seed butter you prefer—almond butter, sunflower seed butter, or cashew butter all work well and add their own subtle flavors.
What sweeteners can I use?
Powdered erythritol or a blend of erythritol and stevia works best for texture and sweetness. Avoid granular sweeteners as they may not dissolve well, affecting dough smoothness.
Why do the cookies seem undercooked when I take them out?
They will appear slightly soft and underbaked because they continue to firm up as they cool. Removing them early ensures they stay fudgy and not hard or dry.
Can I make these cookies dairy-free?
Yes! Ensure your chocolate chips are dairy-free and choose a nut butter without added dairy ingredients. The recipe itself is naturally low in dairy otherwise.
