This keto strawberry mug cake is the best keto sweet treat to fix your cake cravings on a keto diet. A moist vanilla cake with juicy strawberries and even better with a dollop of unsweetened whipped cream on top. Bonus, this low carb dessert is also gluten-free, with only 4.4g net carb per serve.

Keto Mug Cake with strawberries

What’s a keto strawberry mug cake?

A keto strawberry mug cake is a quick keto snack to fix your cake craving in 90 seconds. It tastes like keto strawberry shortcake without the hassle to bake a whole cake. In fact, the cake batter serves only 2 mug cakes,  baked in a coffee mug in the microwave in less than 2 minutes.

Keto low-carb mug cake ingredients

This is an almond flour mug cake recipe, you can’t replace the almond flour by the same amount of coconut flour or the cake would be dry. Follow my coconut flour mug cake recipe if you don’t want to bake with almond flour. All the ingredients needed for this easy mug cake recipe are:

  • Almond flour or almond meal, both work here.
  • Unsweetened almond milk or heavy cream to increase the moist texture of the cake crumb.
  • Baking powder
  • Erythritol – feel free to use any keto sweetener you like, a combo of monk fruit and erythritol or xylitol works fine here.
  • Large egg -at room temperature is the best to avoid flour lumps.
  • Vanilla extract or vanilla essence
  • Fresh diced strawberries – make sure you dice them into small chunks or they will release too much juice and leave the batter uncooked in some areas.

90 seconds Keto Mug Cake

How to make perfect keto mug cakes?

It is pretty easy to make a mug cake as soon as you follow the few basics steps below.

Step 1: Use a microwave-safe ramekin or mug

That might be obvious to some, but not all ramekins are microwave safe! So first, check that your mug or ramekin can be used in a microwave.

Then, make sure you are using a tall enough ramekin or mug. In fact, when you cook in the microwave, cakes rise fast, they usually double in height!

In order to prevent the cake from overflowing, you need a tall mug.

It means that the mug cake batter should only fill about half the mug.  Also, heat diffuses differently in ceramic or in glass. I personally prefer to bake my mug cake recipes in ceramic mugs, it keeps the crumb moist and soft.

Step 2: Prepare the batter in a bowl

This is a recipe for 2 mug cakes. It means that the whole batter is split into two mugs and baked individually. Therefore, preparing the batter in a separate bowl is the best.

Step 3: use the right microwave power

I won’t stress this enough, your microwave oven has different power levels, just like your oven. So don’t assume that baking in your microwave oven is the same as for all other microwave ovens.

In fact, most regular microwave ovens are set to 800W, but some are 600W or up to 1200w. This mug cake recipe bakes for 90 seconds in an 800W microwave oven. So before baking this recipe, check your microwave power and set it to 800W for the best results.

Can I use frozen fruits?

Fresh fruits are the best in mug cakes recipes since they don’t release as much moisture. However, you can use frozen fruits too as long as you cut them in small pieces.

If you want to prevent them from sinking to the bottom of the mug, roll the fruits in 1 teaspoon of coconut flour before adding to the batter.

Also, if strawberries are not available, try other keto fruits like blueberries or raspberries.

Best keto mug cake toppings

A keto mug cake is even better with some topping. My favorite recommendations are:

  • Peanut butter – a drizzle of unsweetened peanut butter is delicious with strawberries.
  • Coconut yogurt – this yogurt is dairy-free, has just a few carbs as it is made of pure coconut cream and probiotic. The combo of creamy coconut yogurt and strawberry vanilla cake is amazing.
  • Unsweetened whipped cream – a classic topping that never disappoints! It makes the recipe taste like a keto strawberry shortcake.
  • Sugar-free chocolate – melt few sugar-free chocolate chips and drizzle on top!

  • In a small bowl, beat egg, vanilla, unsweetened almond milk, baking powder and erythritol.
  • Stir in almond flour until smooth.
  • Stir in 3 tablespoons finely diced strawberries, don't add too big pieces of strawberries or the mug cake would be too moist and wouldn't bake well on these area.
  • Transfer the batter into two tall mug cakes. Your mug cake is going to raise and double in height so make sure you are using a tall mug or the batter will overflow.
  • Bake each mug cake in the microwave, one at a time, power 800W for 90 seconds each. Don't microwave both mug cakes at the same time. Note that if your microwave has a higher power you will need to decrease baking time to avoid a dry mug cake. You can start with 60 seconds, check texture and return to the microwave by 10 seconds burst untissl baked through.
  • Cool 2 minutes before serving to not burn yourself.
  • Enjoy directly in the mug. Top with unsweetened whipped cream and one extra strawberry slice per mug cake.

Baking method

  • Bake at 180°C (350°F) for 12-15 minutes in 2 oven-proofed ramekins.
  • Insert a skewer in the center of the cake to check if it's baked. If it come out dry, it is baked.


  • You can't store a mug cake baked in the microwave, the texture will be chewy, eggy after 1 hour.
Frozen strawberries: you can use frozen strawberries but you must cut them in small pieces before adding them into the batter. Other options are frozen raspberries.

    Wow, made this as my first ever keto food. Amazing taste!!! I am going to try all my favorite recipes from this page now

    • I am so happy you love it! Unfortunately you can’t replace one flour by the other. Coconut flour has 4 times more fiber and it means that you usually need 4 time less to achieve a similar texture. Instead, try my coconut flour mug cake! It’s delicious too and no almond flour! Enjoy, XOXO Carine

    Thank you so much for this recipe. It is the first keto Snack/ dessert that I have really enjoyed. I cannot wait to try your other recipes.
    Thanks again, DI

  3. Followed the recipe to the letter and it didn’t rise at all. Microwave 800 W 90 seconds. Confused.

    • The recipe has 1/2 teaspoon of baking powder so it should raise. These are all the reason it couldn’t is : your baking powder is old and deactivated, you mug is too wide or the strawberries are cut in big pieces adding too much weight to the batter. I hope it help fix the issue next time. Enjoy, XOXO Carine

    My husband loves this mug cake! Thanks for posting such fabulous recipes! I am allergic to eggs & am wondering if you can substitute a “gelatin egg” for the egg in this or other mug cake recipes. Thank you,
