I’ve got a confession to make. I had originally planned to decorate this low-carb cake with pretty buttercream roses, but it was so hot and humid here when I was decorating it that they just wouldn’t work.

My other confession? Now that I’ve seen it, I like it better with fresh flowers.

This sugar-free and keto-friendly cake is a truly spectacular centrepiece to any celebration and I would be 100% thrilled to dig in to it for my birthday. It's a great Valentine's Day treat too!

The pops of dehydrated raspberries scattered through the whipped cream filling takes this healthy cake to the next level (I could have just eaten that with a spoon).

I will add a note though; beetroot powder can be notoriously difficult to use in a cake batter as it can react with the leavening agents, such as baking powder. So, if you don’t have the time or patience for a possible disastrous mistake, use a couple of drops of food colouring to tint your cakes instead.

Ingredients (makes 16 servings)

Cake base:


  1. Preheat oven to 170 °C/ 340 °F (fan assisted), or 190 °C/ 375 °F (conventional). Remove the butter from the fridge and bring to room temperature. Low-Carb Ombre Berry Celebration Cake
  2. Cream butter and Swerve until light and fluffy. Add the eggs, cream, salt and vanilla and beat slowly to combine. The mixture will look like it’s all wrong and curdled, but don’t panic it’ll come right.

  3. In a bowl, combine flours, baking powder and xanthan gum and whisk to remove lumps. Add the flour mixture to the mixing bowl and beat until it forms a batter.
  4. Divide into four bowls and add colouring of choice, ranging from a very pale tint to a strong pink. I have a set of two loose bottomed sandwich cake pans, measuring 20 cm x 5 cm (7.9" x 2"), which are used for layer cakes. I used these tins in two batches.

  5. Spoon your cake batters into your tin(s) and bake for 15-20 minutes. The length of time will depend on your cake tin, so check it regularly.
  6. Remove cakes and place on a rack to cool completely and then bake your next batch.

  7. To make the filling, whip your cream, adding sweetener. Crumble the freeze-dried raspberries.
  8. To make the frosting, whip the butter, cream cheese and sweetener until light and fluffy. Divide the frosting in half, tint one half pale pink and leave the other half white. Set aside.
  9. Trim the domed tops off the cakes and start with the darkest layer on the bottom.

  10. Top with whipped cream and a sprinkle of raspberries and then the next layer of cake. Continue until you reach the palest pink cake on top. You can optionally leave some raspberries for decorating.
  11. Invert this cake so that the bottom becomes the flat, even top.

  12. Using an offset spatula, knife or spoon, gently apply the white frosting over the joins in the cake and then sit it in the fridge for 10 minutes to firm it a little.
  13. Gently apply the white frosting all over the cake, leaving it a little rustic if that’s what you like.

  14. Once that’s done, apply the pink frosting starting with a solid coverage at the bottom of the cake and finishing with a small amount at the 1/3 mark of the cake. Swirl these icings together with your spatula until you reach the desired effect. Refrigerate to set.
  15. Decorate with fresh flowers directly before serving.

Batter very runny.  Not sure what happened.   😞

Was it runny before baking? That won't be an issue at all as the cake will be nice and fluffy once baked. Runny batter could be caused by larger eggs, or sometimes dry ingredients. I always recommend weighing dry ingredients as weights per cup may vary.
(I'm sorry for the delayed response, life gets busy with newborn twins!)

😲 It's my birthday next month, I might have to make this for myself (unless my boyfriend is feeling adventurous!)

Happy birthday! 😊

Wow!  Can this recipe be halved? It looks fabulous but there’s only two of us to enjoy it😊

I had a quick glimpse on the ingredients and it should be easy to halve it. Just remember to adjust the baking time in case you use a smaller cake pan 😊

All of these recipes are so awesome!!  This cakes is of course beautiful!! You should open a restaurant and only serve Keto-Low Carb-GlutenFree dishes!!!  That would be fantastic if only someone would do that here in the South (Mobile, AL-US)
Thank you for bringing all the wonderful recipes to life!

Dee, thank you so much for your kind words!!
