Now, back to the recipe. These healthy tarts are great for Mother's and Valentine's Day or simply when you want to surprise your loved one with a healthy treat. While looking for an inspiration, I found this deliciously looking recipe from Tutti Dolci and I instantly knew I had to make a healthier, gluten and sugar free alternative. This recipe requires some effort but it's not as difficult as it may seem.

For the base, I used coconut flour which is the healthiest low-carb flour substitute. It contains the most stable fats and it's very low in carbs while high in fibre - perfect for the ketogenic diet!

I used paleo-friendly arrowroot powder to thicken the raspberry curd. Arrowroot has more carbs than other thickeners. You can use xanthan gum instead of arrowroot to reduce the net carbs content to 5.7 grams per tart (½ tsp xanthan gum instead of 1 tbsp arrowroot powder). Keep in mind that xanthan gum is not considered paleo-friendly.

Ingredients (makes 8 mini tarts)

Base / crust:
Raspberry curd:
  • 1 cup fresh raspberries (120g / 4.3 oz)
  • lemon zest for garnish (optional)

Note: I used heart-shaped 10 cm / 4 inch tart pans to create 8 mini tarts. When looking for ingredients, try to get them in their most natural form (organic, without unnecessary additives).


  1. Start by preparing the curd. Place 2 cups of the raspberries into a pan.
  2. Add the lemon juice and zest, Erythritol, stevia and water. Bring to boil, reduce the heat and simmer for about 5 minutes.
  3. Take off the heat and blend in a food processor or use a hand blender.
  4. Place the mixture into a fine-mesh sieve and push through using a spoon. Discard the seeds and place the smooth raspberry mixture back in the pan.
  5. Meanwhile, separate the egg whites from the egg yolks. Place the egg yolks into a bowl and mix with arrowroot powder until smooth. Make sure there are no lumps before you add it to the blended raspberries.
    Note: You can use the remaining egg whites for making my Healthy Low-Carb Marshmallows!
  6. Add the egg yolk mixture to the raspberries and process well. Bring to boil over low-medium heat while stirring at all times. When you see bubbles, cook for one more minute and take off the heat. Add the butter and stir until smooth.
  7. Transfer the curd into a bowl and cover with plastic wrap pressing it tightly to the surface of the curd to prevent a skin from forming on top. Chill in the fridge for 1½ - 2 hours.
  8. Meanwhile, prepare the tart base. Preheat the oven to 175 C / 350 F. Crack the eggs into a bowl and whisk with melted (not hot) coconut oil and vanilla extract or vanilla bean seeds. Leave some coconut oil aside for greasing the tart pans or use coconut oil spray.
  9. Add Erythritol and mix in well.
  10. Add sifted coconut flour and process until the batter is thick. The coconut flour will absorb all of the moisture.
  11. Divide the batter into equal part and press it in the greased non-stick tart pans and up the sides to create a "bowl" shape. Place the tarts on a baking sheet and transfer into the preheated oven. Bake for about 10 minutes and keep an eye on the tarts, as the coconut flour may easily get burnt.
    Note: I used mini heart-shaped 10 cm / 4 inch tarts with removable bottom. Alternatively, you can use any silicon pans which work equally well. If you use other types of pans, the crust may get stuck to the bottom.
  12. When done, remove from the oven and let them cool down. Carefully remove the tart base using a sharp knife to lift them up if needed.
  13. Take the curd from the fridge and remove the plastic wrap.
  14. Spoon the curd on top of each crust.
  15. Top with fresh strawberries and lemon zest. Enjoy!

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

Dear Martina,
What a beautiful recipe! Can't wait to try! One question: do you need baking beans or something else that is heavy to hold down the dough/prevent the dough from rising while baking?


Thank you Sarah! You can use baking beans - they always help. I didn't have them when I made this recipe but I've been using them since then just to make sure the crusts stay flat.


This look so delicious! 😄 I was wondering which coconut flour you use and if you could link to it? I have a fat reduced coconut flour and don't think that would work here as it would probably need more fluid?


Hi Rita, I think mine also has some fat removed, otherwise it won't be so "powdery". I think that's how they make it. It does absorb a lot of fluid but it works 😊 I get this one from Amazon:


Beautiful! I'd almost feel sorry to eat it 😊


Oh trust me you wouldn't 😊


Love it! Do you think it would work with strawberries? They are now in season and I'd like to try them instead of raspberries 😊


Thank you! It will - I tried both but preferred the raspberry one. Also, you won't need to add the arrowroot powder if you use strawberries.


This looks fantastic Martina! Well done, it looks really good and I will do my best to make it for Mother's Day. I hope I can succeed. It is actually quite easy, my only worry is that I may fail with the curd.


Thank you Anne, I'm sure you will! It's quite easy, just make sure to incorporate the egg yolks well before you heat the mixture up and keep stirring 😊
