Step-by-Step Preparation
1. Whip the Eggs and Sugar
Start by beating the eggs with sugar and a pinch of salt. The mixture should turn pale, fluffy, and almost double in volume. This is what gives the cake its signature airiness. Take your time here — this step is the foundation of the perfect sponge.
2. Incorporate the Oil
Gradually add the oil while stirring gently. Oil helps keep the cake moist but can also weigh it down if added too quickly. Think of it as coaxing the richness into the fluffiness.
3. Add the Greek Yogurt
Next comes the velvety Greek yogurt. Not only does it lend a soft texture, but it also balances the sweetness with a subtle tang. This is where the cake gets its unique flavor, setting it apart from other sponge recipes.
4. Mix in the Flour and Baking Powder
Sift the flour together with baking powder to avoid clumps and ensure even distribution. Add it gradually to the wet mixture, folding gently. The dough should feel thick yet smooth, ready to bake into a tender sponge.
5. Pour and Swirl
Prepare a baking dish (around 26 cm in diameter) by lining it with parchment paper. Pour in the batter, smoothing out the top. Now comes the magical step: drop “islands” of Greek yogurt and strawberry jam across the surface. With a skewer or knife, create delicate swirls, forming a marble pattern. Each slice will reveal a surprise of jam and yogurt — both a visual delight and a flavor burst.
6. Bake to Perfection
Place the dish in a preheated oven at 180°C (350°F). Bake for 40–45 minutes, or until the surface turns golden and a toothpick comes out clean. The smell alone will fill your kitchen with warmth and anticipation.
7. The Finishing Touch
Allow the cake to cool slightly before removing it from the pan. Dust the top with powdered sugar for a festive touch. Add fresh strawberries if you’d like, or serve it just as it is — simple, rustic, and perfect.
