• 🥚 3 large eggs, room temperature
• 🍬 ⅓ cup powdered erythritol or monk fruit sweetener

How to Make Keto Air Fryer Flourless Chocolate Cake (Step-by-Step)

Step 1: Prep Your Pan

Grease a 6-inch round cake pan or individual ramekins with butter or coconut oil spray. Line the bottom with a small circle of parchment paper. This step saves you from a heartbreaking stuck-cake situation. Future you will thank you.

Step 2: Melt the Chocolate and Butter

In a microwave-safe bowl, combine the chopped sugar-free chocolate and butter. Microwave in 30-second intervals, stirring between each, until fully melted and smooth. Let it cool for 2–3 minutes.

Step 3: Mix the Batter

Whisk the eggs and sweetener together until slightly pale and fluffy — about 1 minute by hand. Add the vanilla extract and salt. Pour in the cooled chocolate mixture and stir until just combined. Don't overmix. Add espresso powder here if using.

Step 4: Air Fry It

• Preheat your air fryer to 325°F (163°C) for 3 minutes
• Pour batter into your prepared pan
• Air fry for 15–18 minutes until the edges are set but the center still has a slight jiggle
• Let it cool in the pan for 10 minutes before removing

Step 5: Serve and Enjoy

Dust with cocoa powder, add a few raspberries, and serve slightly warm. Crowd-pleaser alert — this one disappears fast.

Tips for the Perfect Keto Flourless Chocolate Cake Every Time

Fair warning: a few small details make a big difference here.

• Use quality chocolate. The chocolate IS the cake. Cheap chocolate = meh results.
• Room temperature eggs incorporate better and give you a smoother batter.
• Don't overbake. The jiggle in the center is your friend — it firms up as it cools.
• Every air fryer runs differently. Start checking at the 14-minute mark.
• Individual ramekins bake faster (around 10–12 minutes) and make adorable single servings.

Storing and Reheating Your Keto Air Fryer Flourless Chocolate Cake

This cake stores beautifully, which makes it perfect for meal prep magic.

• Fridge: Cover and refrigerate for up to 5 days
• Freezer: Wrap individual slices tightly and freeze for up to 2 months
• Reheat: 10–15 seconds in the microwave brings it right back to fudgy perfection

Pin-worthy for a reason — this is the kind of recipe you save and actually come back to.
