Step-by-Step Guide to Making Mary Berry’s Coconut Tray Bake
- Preheat the oven – Set the oven to 180°C (160°C fan) and line the tray bake tin with baking parchment.
- Cream butter and sugar – Beat the softened butter and caster sugar together until pale, light, and fluffy. This helps create a soft sponge.
- Add the eggs gradually – Beat in the eggs one at a time, mixing well after each addition. Add a spoonful of flour if the mixture looks like it may curdle.
- Combine dry ingredients – Gently fold in the self-raising flour, baking powder, salt, and desiccated coconut.
- Adjust the consistency – Stir in the milk and vanilla extract until the batter is smooth and evenly mixed.
- Fill the tin – Spoon the mixture into the prepared tin and spread evenly to ensure a level bake.
- Bake until golden – Bake for 30–35 minutes until lightly golden and a skewer inserted into the centre comes out clean.
- Cool before slicing – Leave the cake to cool completely in the tin before cutting into squares.

What I Got Wrong (And How I Fixed It)
- Dry sponge texture – Overbaking caused this, so I reduced the baking time slightly.
- Uneven rise – Levelling the batter before baking solved the issue.
- Dense crumb – Overmixing was the problem; gentle folding worked better.
- Pale top – Moving the cake to the middle shelf improved colour.

FAQs
Why is my coconut tray bake dry?
This usually happens if the cake is baked for too long or in a tin that is too small. Checking the cake 5 minutes before the end of the baking time and using the correct tray size helps keep the sponge soft and moist.
Can I add desiccated coconut on top before baking?
Yes, sprinkling a light layer of desiccated coconut on top before baking adds extra texture and flavour. Just keep it light so the topping does not brown too quickly.
How do I know when a coconut tray bake is fully baked?
The cake is ready when the top is lightly golden, the centre feels firm, and a skewer inserted into the middle comes out clean or with a few dry crumbs.
Can I make a coconut tray bake in advance?
Yes, this tray bake can be made a day ahead and stored in an airtight container at room temperature. The flavour often improves after resting overnight.
