Preheat the oven to 180°C top/bottom heat. Grease a 20–22 cm baking pan and line the bottom with baking paper.
Wash the strawberries, dry them well, hull them, and cut them into small pieces.
Beat the eggs and sugar for 2–3 minutes until light and slightly foamy.
Add milk, sour cream or Greek yogurt, oil, and vanilla. Mix until smooth.
Combine flour and baking powder, then stir briefly into the wet ingredients. Do not overmix.
Gently fold in the strawberries. Reserve a few pieces for the top if desired.
Pour the batter into the prepared pan, smooth the top, and scatter the remaining strawberries over the surface.
Bake for 35–40 minutes, or until golden and a skewer inserted into the center comes out clean.
Let the cake cool in the pan for 10–15 minutes, then remove and cool completely.
Dust with powdered sugar before serving, if desired.
