Blueberry Keto Cake

almond flour keto cake

I’ve done it. Two years, a lot of trials and many errors later, I’ve finally done it. I have created a low carb cake recipe that I’m happy with, and it tastes delicious! Read on to see my perfect keto cake recipe!

I’ve attempted many keto cake recipes in the past and they’ve often been bland or had an odd texture; nowhere near good enough to satisfy a proper sugar craving! But I’ve cracked it and this one I can safely say is a convincing cake alternative, despite having zero added sugar, no flour, no gluten and no artificial sweeteners. It’s a significantly modified version of my keto bread recipe, which you should also check out if you’re following a low carb diet.

The trick is in two ingredients which, despite tasting sweet, can be consumed on a ketogenic diet as they contain a surprisingly low amount of sugar: dark chocolate and blueberries. The fruit adds natural bursts of sweetness whilst the chocolate gives a hint of decadence. Just be sure to use dark chocolate with at least 70% cocoa solids to keep the sugar content down.

cake ingredients

Keto Cake

  • 120g ground almonds
  • 4 medium eggs
  • 3 tbsp extra virgin olive oil
  • 2.5 tsp baking powder
  • 100g blueberries
  • 50g dark chocolate chips (at least 70% cocoa solids)
  • 2 tsp vanilla extract

Pre heat your oven to 200c. In a bowl add the ground almonds, eggs, olive oil, vanilla and baking powder. Because there’s no flour this recipe has less raising agents than a regular cake, so whisk for a couple of minutes to get lots of air into the mixture. Then carefully fold in the blueberries and chocolate chips.

Pour into a greased and lined loaf tin. I recommend using a very small loaf tin, again because the mixture will not rise much so you want it to fill the mould it’s going into. I used a 20x10cm tin.

Bake for 25 minutes.

Did I mention this has no added sugar or flour?! This honestly tastes like a real-deal cake, and I’m so pleased with the outcome. The fruit & chocolate is a heavenly combination and the texture is lovely and light. Here’s how light it is on your waistline:


  • Whole loaf: 1,798 calories, 41g carbs
  • Per slice: 180 cals, 4g carbs

I’ve got a real sweet tooth so for me this is brilliant when I want a treat or fancy a pudding. Regular cakes can easily be triple the calories (and don’t get me started on the carbs) so if you’re a total sugar fiend like myself then this might just help you out!
