Earlier this year I created an easy and tasty snickerdoodle mug cake. Now I’m sharing a low carb version. This cake is flavored with cinnamon and then topped with cinnamon and “sugar” to really feel like a snickerdoodle.

How to Make a Snickerdoodle Mug Cake

  • You will need a microwave-safe mug that can hold at least 12 oz of liquid because the cake will rise quite high while it is cooking.
  • All the ingredients are mixed together with a small whisk until the batter is smooth. The batter is then topped with a cinnamon sugar coating, much like the finish for a snickerdoodle cookie.
  • The cake cooks at full power in the microwave for about 90 seconds. I use an 1100 watt microwave. You may need to adjust time and/or power if you are using a different wattage.

Low Carb Ingredients

  • Instead of wheat flour, this cake is made with superfine almond flour.
  • For the sugar alternative, I used erythritol sweetener granular. It looks just like granular sugar and melts well into the batter.

If you like this mug cake, I have several other low carb mug cakes including a keto chocolate chip mug cake and 3 ingredient keto peanut butter mug cake.

A low carb cinnamon cake that tastes like snickerdoodle cookie in cake form.

Ingredients:

Cake

  • 1 tbsp unsalted butter melted
  • 1 large egg
  • 3 tbsp superfine almond flour
  • 1/2 tsp baking powder
  • 1 tbsp + 1 tsp erythritol sweetener granular
  • 1/2 tsp vanilla
  • 1/2 tsp cinnamon

Cinnamon Sugar Topping

  • 1/16 tsp ground cinnamon
  • 1/4 tbsp erythritol sweetener granular

Directions:

  1. In a microwave-safe mug (that can hold at least 12 oz of liquid), add all cake ingredients. Mix with a small whisk until batter is smooth.

  2. In a small bowl, add topping ingredients. Whisk until evenly blended. Sprinkle over surface of cake.
  3. Cook cake in microwave at full power for about 1 minute 30 seconds. Be careful to not overcook the cake because that will cause the cake to be dry when it cools. Allow the cake to cool a few minutes before eating.

Notes:

  • I use an 1100 watt microwave. You may need to adjust time and/or power if you are using a different wattage.

  1. 312 calories? WOW! Definitely NOT low carb!

  2. This was such a special recipe for me because I used to make Snickerdoodles for my children. I love the taste and the texture, and it’s rare to find both in a low-carb recipe. Combine that with quick, easy, and made from ingredients that most of us have on hand, and you have a real winner here!

  3. I’ve had horrible luck with low carb mug cakes. Got desperate and saw this online. Thought okay I’ll try again…oh my gosh this is so great! Thank you so much!
