Imotska torta

Instructions

1. Preheat the oven to 180 °C and butter a 26 cm round tin.
2. Whisk the eggs with the sugar until the mixture pales, then beat in the oil and milk.
3. Mix the flour, baking powder, salt and cinnamon, then add them little by little to the liquid mixture until you have a smooth, runny batter.
4. Pour half the batter into the tin and spread it evenly.
5. Dot the chopped walnuts and jam over the batter in small spoonfuls, leaving a little space around the edges.
6. Cover with the remaining batter, smoothing it gently, then dust a quarter of the surface with cocoa for a marbled effect if you like.
7. Bake for 35 to 40 minutes, until a knife comes out dry.
8. Let it cool slightly in the tin before turning out, then cut into slices.
