All the flavours of your favourite tray bake but in one show stopping cake. This Keto Brownie Cake is perfect if you’re celebrating something special. Following Keto doesn’t mean you need to stop all the fun, you just have to get creative!

The cream and yoghurt filling with fresh berries brings a wonderful freshness to the rich, decadent indulgence of the brownie.

This Keto Celebration Brownie cake is crumbly, moist, chocolatey just as a brownie should be but without all the sugar and carbs. It almost makes me want to have a birthday 6 times a year!

The brownie sponge base is adapted from these Fudgy Chocolate Brownies included in Martina's bestselling KetoDiet Cookbook.

  1. First, prepare the brownie base. Preheat the oven to 175 °C/ 350 °F. Break the chocolate into small pieces and add to a heatproof bowl with the butter. Place over a pan filled with simmering water and make sure the water doesn’t touch the bowl: only the steam should heat the bowl. Slowly melt while stirring.
  2. When most of the chocolate is melted, remove the pan from the burner and let the mixture continue to melt while stirring. The chocolate mixture should not be hot when added to the dough.
  3. Place the eggs, liquid stevia, and powdered erythritol into a bowl and whisk until well combined. Beat in the chocolate mixture and gently fold in the almond flour, cacao powder, ground chia seeds, baking soda, and cream of tartar and process well. Keto Celebration Brownie Cake
  4. Cut 2 circles in grease proof paper, the size to cover the base of your 20 x 20 cm (8 x 8 inch) sandwich tins and place at the bottom. Grease the sides with a little oil to prevent sticking.
  5. Spoon 2/3 of the mixture into one tin and the remaining 1/3 into the other. Keto Celebration Brownie Cake
  6. Bake in the oven for 16 - 22 minutes. Check the smaller cake after 16 minutes. As it’s thinner it will take slightly less time to cook. The cakes are done when you can insert and remove a skewer without the mixture sticking and are not to soft to touch. Once both are cooked remove from the oven and allow to cool fully.
  7. Remove from the cake tins and place on a wire rack.
  8. Using a large sharp knife cut the larger cake horizontally to form 2 layers. This will give you 3 layers in total.
  9. Whip the cream and yoghurt to a thick, stiff consistency either using a stand mixer or a hand mixer. If using a stand mixer, place the bowl in the freezer for 10 minutes to chill. Do not over beat to prevent splitting. Keto Celebration Brownie Cake
  10. Place one of the cake bases on a serving plate. Spread with half the cream filling and scatter with half the berries.
  11. Top with the next layer of brownie cake and repeat the above step adding the cream and berries. Finish with the top layer of brownie. Keto Celebration Brownie Cake Enjoy! The cake will keep in the fridge for up to 4 days. Keto Celebration Brownie Cake

Will this work with clotted cream? I wonder if I can skip step #9 and use homemade clotted cream instead as a filling on steps #10-11.


Clotted cream sounds like a nice substitution! Just keep in mind it will increase the fat and calories per serving 😊


Oh my this looks so good! My B'day is coming up and I might have to make this for myself to enjoy with family & friends. I'm the only real baker in the bunch. Thanks so much for sharing this.


Too many carbs in yogurt for me. Any suggestions for substitutes other than coconut milk?


Sour cream or crème fraîche would be great lower-carb substitutions 😊


Looks amazing I’m going to try it ty for sharing
