Nutella Sponge Drops

Preheat the oven to 190°C (170 fan) | 375°F | gas 5 and line two large baking trays with non-stick baking mats.

Combine the flour, baking powder, sugar, butter, eggs and vanilla extract in a bowl and whisk together for 2 minutes or until smooth.

Spoon the mixture into a piping bag fitted with a large plain nozzle and pipe 18 walnut-sized domes onto each tray.

Transfer the trays to the oven and bake for 10 - 15 minutes. The mixture should spread a little whilst cooking and the cakes will be ready when springy to the touch. Leave the cakes to cool on the tray then lift them off with a palette knife.
