Instructions

Step 1

1. Preheat your oven to 356°F (180°C). Prepare two 18 cm (7.09 inches) diameter rings. Using a good quality non-stick baking ring or lining the rings with parchment paper can make the extraction much easier.

Step 2

2. Sift the flour, and mix it with salt, yoghurt powder, and baking powder. Sifting ensures no lumps in your dry mixture, giving you a smooth batter.

Step 3

3. In a small saucepan, heat the butter and milk together until the butter dissolves completely.

Step 4

4. In a mixing bowl, whip the eggs with sugar until light and fluffy using a hand mixer or stand mixer on medium-high speed for about 5 minutes.

Step 5

5. Gradually fold the dry and liquid ingredients into the egg mixture in 2-3 stages, ensuring even consistency each time.

Step 6

6. Pour the prepared batter into the rings and bake for 35-40 minutes. Use a toothpick inserted into the center of the sponge to check for doneness—it should come out clean.

Step 7

7. Allow the finished sponges to cool on a wire rack. Once cool, wrap them in cling film and refrigerate for 8 hours.

Step 8

8. Slice each sponge in half to yield a total of 4 sponge layers.

Step 9

9. For the soaking syrup, heat the strawberry puree with water and sugar in a small pot until the sugar dissolves completely, then cool it down.

Step 10

10. For the yoghurt and strawberry mousse, soak the gelatin in cold water until bloomed. Heat the strawberry puree with powdered sugar until light steam appears. Remove from heat and add the yoghurt, mixing well.

Step 11

11. Melt the gelatin in the microwave until it is liquid. Add a small amount of the berry-yoghurt mixture to the gelatin, mix well, and then combine it with the remaining berry-yoghurt mixture. Whip the cream until soft peaks form and fold into the mixture.

Step 12

12. Pour the mousse into 16 cm (6.30 inches) diameter rings and freeze until set.

Step 13

13. For the strawberry ganache, heat the strawberry puree until it begins to steam and pour it over the chopped white chocolate. Stir until smooth.

Step 14

14. Add the butter to the mixture and blend with an immersion blender until smooth. Cover with cling film and refrigerate for 2-3 hours.

Step 15

15. For the frosting, whip the softened cream cheese with the cold yoghurt until smooth. Melt the white chocolate and let it cool slightly.

Step 16

16. Slowly add a small amount of the cream cheese mixture to the melted chocolate, mixing well. Then add the remaining cream cheese mixture and whip until smoothly combined. Use this frosting immediately as desired.

This way, everyone can indulge in this strawberry delight regardless of dietary restrictions.

Faq

  • How do I prevent my sponge cake from sinking?

    Make sure not to open the oven door during baking, as sudden temperature changes can cause the sponge to collapse.

  • Why is my frosting too runny?

    Your cream cheese and yoghurt might be too warm; ensure they are properly chilled before whipping together.

  • Can I use frozen strawberries instead of fresh?

    Yes, frozen strawberries can be used to make the puree, but be sure to thaw and drain any excess liquid to avoid a watery consistency.

  • What's the best way to melt gelatin?

    Soak the gelatin in cold water first, then carefully melt it in the microwave in short bursts to prevent overheating.

  • How can I make my ganache smoother?

    Use an immersion blender to blend the ganache until smooth, and ensure all ingredients are at room temperature before mixing.

  • Can I prepare parts of this recipe in advance?

    Yes, the sponge cakes and mousse can be prepared a day ahead and stored in the fridge, but assemble and frost the pastry on the day of serving for best results.
