Flourless Chocolate Avocado Mug Cake (Paleo, Vegan, Gluten Free)

This flourless chocolate avocado mug cake is super fudgy and chocolatey. It’s also paleo, vegan and gluten free. And it cooks in the microwave in about 2 minutes.

The cake has a fudgy, almost brownie-like texture and you don’t need to be on a paleo or vegan diet to enjoy it.


I have quite a few avocados in my fridge right now which are overripe, so I decided to make some desserts with them. I really love adding avocado to chocolate cakes because it makes them so moist and rich, while also making them healthier.

When you make desserts with avocados, they often look slightly dry when they are finished, but they don’t taste dry at all.

Since I’ve been creating paleo mug cakes, I wanted to create a paleo version of my chocolate avocado mug cake. But as an additional challenge, I wanted to make the cake eggless. Most of the paleo cakes I’ve made rely heavily on an egg to bind the cake and help make it fluffy. I wanted something that was more dense and fudgy, so I didn’t want to use an egg.

Because the cake doesn’t use an egg, you can even undercook it slightly, leaving you with a gooey chocolate cake.

To bind the cake together, I used almond butter. You can substitute with other nut butters, but I like using almond butter because it has a mild enough flavor, allowing the chocolate to be the star.

This cake came out exactly as I hoped. Okay, it took me about ten attempts to get to this result, but I’m really happy to share this final version with you today. Because there is no egg, the crumb is looser than many of the other paleo mug cakes I’ve shared so far. Therefore, it wouldn’t work well as a cupcake. But since it is meant to be eaten in the mug, the looser crumb shouldn’t be an issue.

I topped mine with some chocolate syrup. It’s definitely not necessary, as the cake is rich enough on its own. But I wanted to dress the cake up a little as it does look plain on its own.

  • 4 tbsp mashed avocado 48 grams; or about half a medium avocado
  • 2 tbsp almond butter
  • 3 tbsp maple syrup
  • 1/4 tsp baking powder  please note commercial baking powder is not paleo so you may need to make your own homemade paleo baking powder
  • 2 tbsp unsweetened cocoa powder


  • Add all ingredients into a large, microwave-safe mug. Mix with a small whisk until batter is smooth. Batter will be thick.
  • Place cake into the microwave and cook at full power for about 2 minutes, or until surface of cake looks done. Allow cake to cool a few minutes before eating.


  • Make sure to mash the avocado thoroughly before measuring out your 4 tbsp, as 4 tbsp of mashed avocado is more than just 4 tbsp of scooped out avocado flesh.
  • For best results, use very ripe avocados as they are easier to mash.
  • You can substitute almond butter with other nut butters like cashew butter or peanut butter. I chose almond butter because it has a milder flavor which gets covered by the chocolate. If you use peanut butter, you will likely taste the peanut butter flavor.
  • I used this homemade chocolate syrup on my cake. Please note that the syrup is not paleo. You can most likely make a paleo version by using coconut sugar in place of granulated sugar.

  1. This was the best chocolate mug cake recipe I have tried!

  2. Does the nutritional value include the chocolate sauce

  3. Can I use sorghum flour

  4. Hello all .. I was wondering if I can use frozen avocado … I get it from Costco …

  5. It’s a gray and rainy day in Pa so I wanted  to try your recipe and I can only say oh my goodness heavens to Betsy holy moley this is delish!  My avocado hating hubby loved it too and I will be making this again, already pinned!. Thanks for this magical and delectable recipe???

  6. Just wanted to say, I make this recipe allllll the time. Thank you for your content!! 

  7. This recipe is unreal! I substituted one of the tablespoons of maple syrup for some espresso (1 Tbsp water + 1/4 tsp instant espresso powder) and the flavor was amazing. I’m amazed how decadent something made with these simple, healthy ingredients can be. This is an instant favorite- will definitely make again!

  8. I made this for my mom a month before her birthday and she is crazy about it. She can’t have gluten, egg , dairy or soy, sugar, meat, and a bunch of other things. I was requested to make some for her 2nd 25 birthday. She can’t stop eating this heavenly goodness! Make sure you like the nut butter or sunflower butter you use because it’s a very strong taste.

  9. Yuuuuuuuum ? Thank you so much for the recipe. I only had 1.5 tablespoons maple syrup so I subbed in unsweetened almond milk and vanilla extract for the rest. Threw chocolate chips and pecans on top as it was cooling down. I’ve never had a mug cake work before and this was amazing ? ??

  10. Crazy delicious!  

  11. Have made this mug cake recipe multiple times and is a regular hit with guests and family members! Used cacao powder to reduce sugar intake and turned out delicious. Topped with raspberries and 80% dark cacao chips to create a natural “syrup”. Wonderful recipe, bravo!

  12. What is the power of the microwave? 

  13. So good. This is the closest mug cake I have tried that had the consistency of an oven cake!!

  14. So good!! I added a little bit of chocolate chips. This is definitely a new favorite?
    I can’t wait to try some of your other recipes.

  15. Hi, if anyone DOES try this in the oven, post if you think of it!  I don’t microwave but I’d love to try this recipe!

    • I tripled the recipe and made 5 muffin portions. Cooked it 160degrees fan force, for approx 25mins or until skewer comes out clean. If you want it a bit more gooey, take it out a little earlier. 

  16. Would love to try this recipe but I don’t have a microwave, do you have any idea of how I should cook it in an oven? Temp and how long? 
    Looks absolutely amazing and works for us vegans ???

  17. Wondering how long and at what temperature you would use for an oven. I don’t have a microwave.

  18. Hi have you tried adding an egg?  

    • I don’t recommend adding an egg. It will completely change the texture of the cake. The cake should not come out dry. Make sure you add the full amount of all the ingredients listed and you may have to cook it for a little less time.

  19. Using the ingredients I had on hand, I edited the recipe to include 2 tablespoons peanut butter, 1.5 tablespoons honey, 1.5 tablespoons water, a little less avocado, baking soda, and cocoa powder. With a little bit of chocolate syrup on top, it is superb. I love no added sugar (besides the choc syrup and honey). The texture is amazing!

  20. WoW! The texture reminds me of flour, and there are no flour, it’s incredible!

  21. Just made this using pumpkin puree instead of avocado. Turned out great! It came out so moist- almost pudding-like. It is verrryy rich, though, and I wish I had split it with my boyfriend. For a little more cake-like texture, two tablespoons of coconut flour would probably work (I put 1TB in my boyfriend’s cake and it only made a little different in the pudding-like texture).

  22. Have tried many mug cakes, and recently had to stop using almond flour. With this recipe I won’t even miss the flour. DELICIOUS!

  23. Looks healthier & good. Didn’t try yet 

  24. This mug cake looks delicious!! I love this recipe! And the photos are so beautiful!

  25. Kirbie – totally awesome recipe. I followed your recipe except for the maple syrup being I’m diabetic and on the keto diet. So to lessen carb count, I substituted with 1.5T stevia blend and 2t water for the maple syrup. I made one for my adult son and he enjoyed it too. Who would have thought that avocado and almond butter could create a cake. Thank you for sharing your creativeness!

  26. This is just the kind of cakes I simply LOVE! Looks absolutely delicious!
