What is Keto Mug Cake?

A keto mug cake is made with low carb ingredients and cooked in the microwave for less than 2 minutes until fluffy. It’s a quick sugar-free dessert that’s low carb, grain-free, and gluten-free.

Are Blueberries Keto-Friendly?

Berries have the lowest sugar content of any fruit, including blueberries, strawberries, and raspberries. Blueberries are perfect for a ketogenic diet. So you can incorporate them into your daily macros.

Why Is This The Best Keto Blueberry Mug Cake Recipe

  • Made with only 7 naturally low-carb ingredients.
  • Super light, moist, and fluffy
  • Tastes similar to a bakery style muffin minus the carbs
  • Only 5g net carbs per serving.
  • Super versatile – you can use your favorite berries such as raspberries, strawberries, or blackberries,

Ingredients You’ll Need

You’ll need just a few easy-to-find ingredients to make this delicious mug cake. Here is a note on the ingredients.

  • Coconut Flour and Almond flour – I’m a huge fan of using both flours to get that perfect texture that resembles a regular fluffy muffin.
  • Blueberries – I used fresh blueberries; you can also use frozen ones; make sure to coat them in coconut flour so the cake doesn’t become mushy due to the extra moisture.
  • Sweetener – I used granulated Erythritol, but you can also use Monk Fruit sweetener or Allulose.
  • Eggs – use large eggs at room temperature; otherwise, the mug cake may have an eggy taste.
  • Baking Powder – helps the cake rise.
  • Lemon –  I used lemon extract and lemon juice to get the best lemon flavor. Feel free to replace it with vanilla extract.

How To Make Keto Blueberry Mug Cake

Another great thing about this recipe is that it is extremely easy to make using just a tall mug. Here is everything you have to do:

  1. Mix all the ingredients into a microwave-safe mug that’s large enough. Once the batter looks smooth, fold in the blueberries.
  2. Microwave and cook for 90 seconds. If the center is still moist to touch, keep cooking at 10 seconds intervals until ready.
  3. Remove the mug from the microwave and let it cool for a few minutes.

How to Serve Blueberry Mug Cake

Tips and Variations

  • Add chocolate chips or chopped nuts to the batter.
  • Make sure to use a tall 8 oz mug.
  • Dust the blueberries in coconut flour to prevent them from sinking to the bottom of the cake.

Storage Ideas

  • Fridge – Wrap the cooked mug cake in plastic wrap and store it in an airtight container for up to 2 days. Reheat in the microwave before serving.
  • Freezer – This keto blueberry mug cake is freezer friendly and can be stored in the freezer for up to 1 month.
