There is so much happiness to be found in a good chocolate tart. A tart to slow your pace, curl up with and forget the world exists. A cake for ‘me time.’ This is it.

Cacao, coconut oil and avocado, a velvety smooth filling to coat your mouth better than any dairy milk. This is a recipe for the mother of all chocolate tarts, my gift to those of you who appreciate the value of good cake. What’s more, it’s low carb and refined sugar free. It’s positively good for you cake!

  5. Divide the chocolate filling into 6 and fill each of the keto tart crusts. Spread evenly across the base to the edges using a spatula.
  6. Place in the fridge to set for at least an hour until set. Option to place in the freezer for 45 minutes if in a hurry. Low-Carb Chocolate & Lime Tarts
  7. Grate the dark chocolate and lime zest. Remove the keto chocolate tarts from the fridge or freezer and top with grated chocolate and lime zest. Keep in the fridge until ready to serve. Option to remove them 5 minutes before serving if you prefer a softer filling. I like mine straight from the fridge. Pairs well with this keto vanilla soft scoop ice cream, full-fat plain Greek yogurt or coconut yogurt.

Food is one of life’s most powerful medicines. I’m a true testament that once you find the right approach for you, you can overcome poor health through the healing power of food.

I believe the secret to radiant health starts and ends with a healthy gut so my recipes are all grain, gluten and refined sugar free. Most are also dairy-free.

I liked these very lightly sweet tarts. I only used 1/2 the lime juice & with the zest on top thought that gave a good amount of lime flavor. I don’t think my non keto friends appreciated them as much, but my unsuspecting daughter loved it.


Thank you Melanie! That is always the case when I use little to no sweetener. We are used to it and prefer it but my non-keto friends are not so convinced 😊
