1. Preparation and Initial Whisking
Preheat the oven to 180°C. In a large bowl, crack the eggs and whisk them with electric beaters until they double in volume. Add the yogurt and the Castelló Stevia + Erythritol 1:1 , continuing to beat until the mixture turns pale and the sweetener is fully incorporated.
2. Adding the Dry Ingredients and Flavors
Add the sifted flour together with the Baking powder . Then add the extra virgin olive oil and the lemon zest, mixing everything very well to avoid lumps.
3. Baking and Cooling
Line a baking tray with parchment paper and pour in the mixture. Bake for 35-40 minutes. Do the toothpick test: if it comes out clean, the sponge cake is ready. Let it cool before unmolding.
