Blueberry Almond Mug Cake (Paleo, Gluten Free)

This fluffy blueberry almond mug cake cooks in the microwave and is ready in minutes. It’s also wheat flour free, gluten free and paleo.

I’ve been playing around with trying to create a paleo version of one of my mug cakes. Over the years, I’ve shared quite a few mug cake recipes on this blog and while I’ve made several flourless ones, this is the first paleo one.

This cake is super fluffy and the texture is similar to a regular cake even though it doesn’t contain any wheat flour. I love the bursts of blueberries and the mild almond flavor throughout.

I dusted mine with a little powdered sugar and some sliced almonds. The sugar I used is not paleo but you can use a paleo powdered sugar (you can buy or make your own) if you are following the paleo diet.

Blueberry Almond Mug Cake (Paleo, Gluten Free)

This single serving mug cake cooks in the microwave and is ready in minutes. It is also paleo and gluten free.


  • 3 tbsp super fine almond flour
  • 1 tbsp coconut flour
  • 1/2 tsp baking powder (for a paleo version you will want to make your own baking powder rather than using commercial baking powder)
  • 1 1/2 tbsp maple syrup
  • 1 large egg
  • 1 tbsp milk (you can use any kind, almond milk if you are keeping it paleo)
  • 1 tbsp olive oil
  • 12 fresh blueberries
  • 1 tbsp sliced almonds
  • powdered sugar for dusting (to keep it paleo, you can make paleo powdered sugar with coconut sugar)


  1. In a microwave-safe mug, add all ingredients except blueberries, slices almonds and powdered sugar. Mix batter with a small whisk until smooth.
  2. Gently drop blueberries on top. Do not worry about mixing them in because they will sink when cooking.
  3. Sprinkle sliced almonds over surface of batter.
  4. Cook cake in microwave at full power for about 1 minute 30 seconds or until cake is done. Top with powdered sugar if desired. Cake is best eaten warm.
  • Be sure to use super fine almond flour for best results.
  • Do not leave out the coconut flour or try to substitute with almond flour. The coconut flour helps to expand and make the cake fluffy.

  1. glad you added the comment about the coconut flour as i was thinking to myself: i don’t have coconut flour, i’ll just try this with only the almond flour” – lol. I’ve seen coconut flour here and there but… cannot remember exactly where. Where in San Diego County do you purchase it?

    • I buy mine from Sprouts! I know a lot of people seem to have almond flour but not coconut in the cupboards. It makes such a big difference though using both and comes in handy for most paleo or gluten free baked goods.

  2. Love quick meals. This one is perfect week breakfasts for my small family of two 🙂 Thank you so much !

  3. What would you advise if I wanted to make this in the oven in a larger batch? I don’t have a microwave.

  4. I made the mistake of using a standard size coffee mug and therefore made a mess in the microwave. It’s good though! I added a pinch of cinnamon and vanilla.

  5. Oh my this is awesome. I made the mistake of leaving out the coconut flour because I sometimes feel it has a chaulky feel. the first time I made it. It was too wet, but tasted good. I made it the second time using the coconut flour and it was perfect. I added cinnamon and vanilla and used 1 tablespoon maple syrup and 1 tablespoon of coconut sugar. Sooo good. My daughter and I have Celiac’s and mug cakes have made us so happy. THANK YOU SO MUCH for your wonderful recipe!
