Made with coconut sugar, this has a lovely tropical flavour – and at just 12g of sugar and 233 calories per serving, it's a lighter choice than many ready-made cakes. We’ve swapped calorie-laden buttercream for a delicious Greek-yogurt topping

Step by step
Get ahead
Make the cake up to a day ahead. Once cool, store in an airtight container. Ice and decorate just before serving.
- Preheat the oven to 180°C, fan 160°C, gas 4. Line a 20cm x 30cm traybake tin with baking paper. Spread the desiccated coconut out on a baking tray, and spread the coconut flakes for the topping out on a second. Bake both for 3-5 minutes until lightly toasted – keep an eye on them, as coconut turns quickly. Tip onto separate plates to cool.
- Whisk the butter and coconut sugar together until pale and creamy, then begin to gradually whisk in the beaten eggs. If the mixture starts to curdle, add a couple of tablespoons of flour. Fold in the remaining flour, baking powder, a pinch of fine salt, the cooled desiccated coconut, lime zest and juice and vanilla extract until well combined. If the mixture seems too stiff, add the milk to loosen.
- Scrape into the traybake tin, level the surface and bake for 20-25 minutes or until a skewer inserted into the middle comes out clean. Leave to cool in the tin for 15 minutes, then transfer to a wire rack to cool completely.
- Once completely cool, make the frosting by mixing the yogurt with the honey and lime juice in a bowl. Spread on top of the cake, and scatter with the toasted coconut flakes, dried mango and lime zest.
