Mary Berry’s jam and coconut sponge is a traditional British traybake featuring a soft, moist sponge base topped with jam and desiccated coconut. This cake has a nostalgic feel and combines a fluffy sponge with the sweetness of jam and the tropical hint of coconut, making it an irresistible dessert or tea-time treat.
Preheat your oven to 180°C (160°C fan) and line an 8×12-inch baking tin with baking paper.
In a large mixing bowl, use an electric mixer to cream together the softened butter and caster sugar until light and fluffy, about 3-5 minutes.
Add the eggs one at a time, beating well after each addition. Add the vanilla extract and mix until fully incorporated. If the mixture begins to curdle, add a spoonful of flour to bring it back together.
Sift the self-raising flour into the bowl and gently fold it into the mixture using a spatula. Add the milk and mix until the batter is smooth and has a soft dropping consistency.
Pour the batter into the prepared baking tin, spreading it evenly with the spatula.
Bake in the preheated oven for 25-30 minutes, or until a skewer inserted into the center comes out clean and the sponge is golden. Allow the cake to cool in the tin for a few minutes, then transfer it to a wire rack to cool completely.
Once the sponge has cooled, spread a layer of jam evenly over the top of the cake. Sprinkle the desiccated coconut on top, ensuring it covers the jam layer.
Cut the cake into squares or slices and serve. Enjoy with a cup of tea or as a sweet treat for any time of day.
