Bake a simple and satisfying family dessert with our easy jam sponge recipe – only a handful of ingredients and 30 minutes to make.
Preheat the oven to 200 °C/180 °C with convection/gas 6. Grease a 25 cm square tin or a 20 × 30 cm rectangular tin with butter.
Beat the butter, sugar, flour, eggs and vanilla extract until a smooth batter forms. Spread the jam over the bottom of the tin, then pour the batter on top. Smooth evenly. Bake for 20‑25 minutes, until the sponge is light‑golden and risen, and a skewer inserted in the centre comes out clean. Serve warm with custard, cream or ice cream.
