Lime and Cardamom Cake

Lime and Cardamom Cake with Creamy Coconut and Pistachio Topping

Inspired by lemon drizzle cake and key lime pie, this fresh and fruity lime and cardamom cake is a great way to welcome spring into the kitchen. The subtle warmth of the cardamom adds an extra layer of depth to the sharp citrus, and the sweet coconut cream topping and crunchy pistachios balance the textures and flavours. The Swiss meringue buttercream may sound daunting, but it’s really simple to make. it just takes a little longer than regular buttercream, and you’ll end up with a lighter alternative that really complements the coconut.

250g unsalted butter (at room temperature)

275g golden caster sugar

4 medium eggs

275g self-raising flour

A pinch of salt

8 green cardamom pods

100g Greek yoghurt

For the coconut swiss meringue buttercream:

2 egg whites

130g caster sugar

150g unsalted butter (at room temperature)

1 tsp coconut cream

A pinch of salt

3. Beat in the eggs one at a time until smooth.

6. Pour into the cake tin and then bake for 50 minutes.

7. Once baked, leave to cool completely in the tin. When cool, remove from the tin and set aside.

8. For the coconut Swiss meringue topping, begin by whisking together the egg whites and caster sugar in a heatproof bowl for about 30 seconds.

9. Place the bowl over a saucepan of boiling water, then continue to whisk for several minutes until you have a smooth white consistency. There should be no sugar granules remaining.

10. Transfer the warm mixture to a larger bowl and continue to whisk for several more minutes until it is thick and able to form stiff peaks.

11. Allow to cool, then beat in the butter, one tablespoon at a time.

12. Beat in the coconut cream and salt.

13. Spread the buttercream over the top of the cake and smooth out using the back of a spoon. If you have a little buttercream left over, you can serve this alongside the cake!

14. Sprinkle over the desiccated coconut.

15. In a food processor, blitz the pistachios into a fine crumb and then sprinkle over the top of the coconut.

16. Enjoy your lime and cardamom cake!
