Seeded Sponge Slice
Preheat the oven to 170°C (150°C fan) | 325°F | gas 3. Grease and line a 18 cm | 7” springform cake tin with greaseproof paper.
Combine all the ingredients for the cake in a large mixing bowl and beat with an electric mixer for 2 minutes until smooth.
Spoon into the cake tin and drop a few times from a short height to help evenly distribute the batter in the tin.
Bake for 25-35 minutes until golden and risen and a cake tester comes out clean from the centre.
Remove from the oven when ready and let the cake cool in the tin for 15 minutes before turning out onto a wire rack to finish cooling.
Cut into slices when cool and serve on plates.
