How to Make A Keto Coconut Mug Cake

  • All the ingredients except the shredded coconut are whisked together until smooth. Then, the shredded coconut is stirred in.
  • The cake is cooked for about 1 minute and 30 seconds in the microwave or until fully cooked.
  • I recommend topping the cake with coconut whipped cream or regular whipped cream before serving.

Tips for Cooking this Mug Cake

  • This mug cake is meant to be a single serving, so it will just fill an 8 oz mug. However, it does rise quite high when it cooks, so it should be cooked in an oversized mug.
  • If you want a nice presentation, cook it in the larger mug and then replate it in an 8 oz mug.
  • You can replace erythritol with Swerve or another similar low carb granular sweetener.
  • You do not need to grease the mug. The cake will pull away from the sides when it is finished cooking.

Ingredients

  • 1 tbsp unsalted butter melted
  • 2 tbsp coconut flour
  • 1/4 tsp baking powder
  • 1 large egg
  • 1 tbsp granular erythritol
  • 2 tbsp milk can use coconut, almond or regular
  • 1/2 tbsp shredded unsweetened coconut

Instructions

  • In a large microwave-safe mug, add all ingredients except shredded coconut. Mix with a small whisk until batter is smooth and egg has been completely beaten in.
  • Stir in 1 tbsp of shredded coconut.
  • Cook cake in microwave at full power for about 1 minute 30 seconds or until cake is fully cooked. Cake will initially rise very high before sinking back down when it stops cooking.
  • Allow cake to cool a few minutes before eating. If you want a nicer presentation, you can remove the cake from the large mug and place it into an 8 oz mug. Top with whipped cream or coconut whipped cream before serving.

Notes

  • The cake can be topped with regular whipped cream sweetened with erythritol or coconut whipped cream (replace the powdered sugar with powdered erythritol)
  • I used So Nourished erythritol sweetener granular* in the cake.
  • I used Bob Red Mill's coconut flour.*
  • I cooked my cake in an 1100 watt microwave.  You may need to adjust time and/or power if you are using a different wattage.

  1. Hi, do you think this can be baked As mini muffins in the toaster oven? And do u think I can sub regular sugar? My daughter is doing allergy treatment and needs to dose coconut and eggs so I think this recipe would be perfect for her except she’s not too keen on the texture of mug cakes when it cools but can’t eat it fast enough while it’s warm. Thanks so much. 

  2. Super easy and so delicious!
