Easy Keto 1 Minute Lemon Poppy Seed Mug Cake – Dairy-Free

Easy Keto lemon poppy seed 1 Minute keto mug cake social

If you are looking for a perfectly moist and fluffy lemon cake, you are in the right place.

I think you’ve noticed that when I want a quick dessert I’m always making my self a keto mug cake. Add all the ingredients in a mug, stir, stir and in less than 10 minutes I have a great treat to enjoy.

I had to adjust the ingredients before I came to realize the perfect flavour and consistency of the Lemon Poppy Seed Mug Cake recipe. I would not call the first attempts failures because I still ate them with pleasure. It really depends on your taste how you want the cake. If you want it more sour and sweet tasting, add more lemon juice otherwise reduce the amount of sweetener to your taste. Do the same thing with the sweetener.

This recipe is free of sugar, dairy, gluten, and grains. 

Lemons are a little higher in carbs, but they also packaged with health benefits and the taste? Divine!

Anyways, this recipe it’s to die for especially when craving something sweet, yet fresh and soft.

What will you need for this amazing keto recipe?

  • 1 egg
  • coconut flour
  • coconut oil
  • poppy seeds (of course)
  • lemon juice or lime juice
  • coconut milk or water
  • baking powder
  • your favourite carb-free sweetener (I used this)

If you are a keto veteran, you may already have all the ingredients in your kitchen. So, what are you waiting for? Make this recipe now!

You have a printable version at the end of this recipe.


Start by beating the egg with a fork.


Over the beaten egg add all the liquid ingredients:  the melted coconut oil (you can also use butter), the lemon juice, the coconut milk, and water. So, easy!

Tip: You can add as much or as little lemon juice as you love.

Now add all the dry ingredients.

Add the coconut flour.

The best part: add the poppy seeds, a pinch of baking powder and 1-2 teaspoons of your favourite sweetener and mix well until you get a nice cake batter consistency.



Transfer the mixed ingredients in your favourite greased mug. Let microwave for a minute (or more, depending on your microwave power- they are all different).


This how it should look like when you get it out of the microwave. Make sure you don’t overcook it (I did it many times, not bad but a bit crumbly and not so moist inside).


Let it cool down for a few minutes in the mug, and then transfer it to your plate.

I love to squeeze some lemon juice on top.
