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.
