It’s Christmas Eve!!

So.. I’m dropping one last, last minute holiday dessert recipe because who doesn’t love chocolate cake? Better yet… who doesn’t love a rich, decadent and spiked chocolate cake thats easy and quick to make?

It’s a “dump and blend” kinda chocolate cake so ANYONE can make this. It’s full proof, no fail and the result will blow. your. mind.

Ingredients to Make Flourless Chocolate Rum Cake

Typically, flourless chocolate cake contains eggs where the egg white gets whipped to bind and leaven the cake. But to keep this chocolate cake vegan and eggless, we’re going to do a couple of swaps.

  • Hazelnut butter + Soft tofu + Tapioca starch: these 3 ingredients will help bind and give moisture.
  • Baking powder: will help the cake rise without needing to whip egg whites.

In addition, we’ll need the following:

  • Coconut sugar: keeping this cake refined sugar free! Any dry sugar can be used here.
  • Hazelnut meal: acts as our “flour”, is the base and helps absorb all the liquid. Almond meal can also be used.
  • High quality dark chocolate: makes this chocolate cake super decadent, rich and fudgy.
  • Cocoa powder: helps intensify the chocolate flavour and absorbs extra liquid.
  • Rum: to make this chocolate cake alcohol free, substitute black coffee.

How to Make Vegan Flourless Chocolate Rum Cake

Like I mentioned before, most flourless cakes require beating the egg whites but not this recipe. All the ingredients just go into a food processor, transferred into a spring form pan and baked- thats it! Crazy easy and it takes less than 10 minutes to put together. You could probably also pour the batter into a 8×8 inch brownie pan and cut them into squares instead!

What does Flourless Chocolate Cake Taste like?

And the result? Thick, rich and decant. It is NOT one of those light and fluffy chocolate cake. It’s almost a cross between a moist brownie and truffle… but still has a cake like crumb. The addition of the hazelnuts and rum takes it to the next level and just makes this chocolate cake that much more special.

Tips to Making Perfect Vegan Flourless Chocolate Rum Cake

  • Make sure the ingredients are room temperature: This helps prevent the chocolate from stiffing up too fast. Working in a warmer kitchen also helps with this.
  • Let it cool and sit in the fridge for at least 3 hours: Straight out of the oven, it’s very gooey. It sets when cooled and the flavour intensifies when left overnight.
  • Use high quality dark chocolate and cocoa powder: It really does make a difference in this chocolate cake. I like to use minimum 70% dark chocolate.

How to Store Flourless Vegan Chocolate Cake

Once completely cooled, wrap or cover tightly so that the cake doesn’t dry out. It keeps well in the fridge for up to 3 days. Or, freeze for up to 2 months. Let it thaw in the refrigerator overnight when ready to eat.

  1. Hello Lisa ! I really want to try this recipe but i cannot find tofu these days ahahah which ingredient can replace it ?
    Thanks 😁

    1. Hi Cheima!
      I’m sorry, this cake is based on tofu- I can’t think of a substitute for this recipe. I’m working on a chocolate brownie recipe with the similar texture using black beans so perhaps you can try that one when its out! You can also try my eggplant chocolate cake here on the blog- it’s super rich and fudgy as well. 🙂
