Healthy Raspberry Curd Hearts

Before we get to the details of this gorgeous treat, I'd like to inform you of Facebook's recent policy change. As some you may know, page posts are now only shown to ~ 5% of followers and this will get even worse. Apart from my Facebook profile, if you don't want to miss any of my posts, you can follow me on:

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.

Preparation time:

Hands-on:        30 minutes
Overall:         2 - 2.5 hours

Nutritional values (per tart):

Total Carbs12.7grams
Net Carbs6.6grams
of which Saturated10.1grams
Magnesium23.4mg (6% RDA)
Potassium170mg (8.5% EMR)

Macronutrient ratio: Calories from carbs (14.5%), protein (15.3%), fat (70.3%); only 2.3 g net carbs per crust (without topping)

Ingredients (makes 8 mini tarts):

Base / crust:

Raspberry curd:

  • 2 cups fresh or frozen raspberries (250g / 8.7 oz)
  • juice from ½ lemon
  • 1 tsp lemon zest
  • ½ cup powdered Erythritol (non GMO) or other healthy low-carb sweetener from this list (80g / 2.8 oz)
  • 15-20 drops stevia (Clear / Berry)
  • 1 tbsp arrowroot powder (9g / 0.3 oz)
  • 2 large egg yolks, free-range or organic
  • 1 tbsp butter, unsalted or coconut oil (15g / 0.5 oz)
  • 2 tbsp water


  • 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!

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 Smile

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 Smile

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.

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

Oh trust me you wouldn't Smile

This look so delicious! Laughing 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 Smile I get this one from Amazon:
