Recipe Notes, Substitutions & Variations

  1. Be careful not to overcook this mug cake. If you do it will turn out dry and flavorless.  The first time I followed the original instructions for this chocolate mug cake recipe which said to cook the cake in the microwave for 1-1/2 minutes on HIGH. I followed this instruction and my cake turned out very dry and tasteless. Cooking times for microwaves can be tricky due to their size and power ratings (wattage). This is why it is better to start off cooking for less time and checking it more frequently, so you won’t end up with a dried out cake. 
  2. Make sure to use a microwave-safe mug or ramekin that is large enough to allow room for the batter to expand while cooking.
  3. Air-Fryer Gluten Free Chocolate Mug Cake: I also cooked this single serving cake in my Cosori TurboBlaze™ air fryer. On my Cosori, I used the “Bake” function for 10 minutes at 350F degrees and it turned out perfectly. I also checked on it after 5 minutes, just to make sure I wasn’t overcooking it.
  4. You could also mix this directly in the mug, but I found this to be a little too difficult for getting all the ingredients thoroughly mixed, so I opted to first mix the ingredients in a small bowl (affiliate link).then pour them into the lightly greased ramekin or coffee mug.

Variations & Substitutions

No peanut flour? Use almond flour instead. Both have similar nutty profiles and work well in similar recipes.

No dark cocoa powder? Any unsweetened cocoa powder will work.

No Eggs? Substitute the same amount of unsweetened applesauce.

No Unsweetened almond milk? Any dairy or non-dairy milk will work: coconut milk beverage, soy milk, hemp milk, non-fat dairy milk, oat milk, etc.

Possible additions? A teaspoon or two of chocolate chips, a pinch of espresso powder, a pinch of cinnamon would all be delicious.

Serving Suggestions

Enjoy this cake plain directly from the mug, or removed to a small plate. Optional toppings include: lite whipped topping, nonfat frozen yogurt, high protein low calorie ice cream (like halo top) fresh berries, sprinkles or jimmies.

FAQs

How to make flourless chocolate mug cake in the Air Fryer?

Follow steps 1-4 to prepare your cake. Press the “Bake” function on your Cosori TurboBlaze™ and adjust the temperature to 350F degrees and the cooking time to 10 minutes.

Cook, checking progress at the 5 minute mark and adjusting cooking time as necessary. My cake was perfectly done after 10 minutes. (If you are using a different model of air fryer, your instructions may vary.)

How do you know when a mug cake is done?

Test if your mug cake is done by gently touching the top with 1 or 2 fingers. If it feels slightly sticky it is done. If it doesn’t, you may have nuked it a little too long.

Why did my mug cake overflow? 

Avoid overfilling your mug with ingredients when making mug cakes. These treats rise during the cooking process, so filling the mug beyond two-thirds of the way can lead to a messy overflow situation in the microwave. Just like with any other baked good, mug cakes expand as they cook. Keeping the batter below two-thirds of the mug’s capacity helps prevent any spills or messes during the heating process.
