Spelt flour gives this cake a slightly nutty, soft crumb that holds up well to a generous lime drizzle. It bakes faster than a standard wheat cake and stays moist longer, which makes it a good choice for baking ahead.
The lime syrup goes on while the cake is still warm. It soaks through the top layer and concentrates just at the surface, giving you a thin, slightly crunchy sugar crust over a damp, fragrant crumb underneath.
Toasted coconut adds texture and a mild sweetness that keeps the lime from reading too sharp. You can use desiccated or flaked coconut – both work, though flaked gives a more visible finish on top.
This is a one-bowl bake. No creaming, no stand mixer needed. The batter comes together in about fifteen minutes.

Ingredient Notes
- White spelt flour: White spelt flour gives a lighter crumb than wholegrain spelt. You can swap half for wholegrain spelt flour, but the cake will be slightly denser and more earthy in flavour.
- Coconut oil: Use refined coconut oil if you want a neutral flavour, or unrefined for a stronger coconut note. Melted unsalted butter works as a direct substitute.
- Full-fat coconut milk: Shake the can well before opening. The fat content keeps the crumb moist. Low-fat coconut milk can be used but the texture will be slightly drier.
- Fresh lime juice and zest: Use fresh limes – about 3 medium limes for both the batter and the syrup. Bottled lime juice lacks the brightness needed for the drizzle.
- Caster sugar: Caster sugar dissolves faster in the syrup. Granulated sugar works but takes an extra minute of stirring over heat to fully dissolve.
- Desiccated or flaked coconut: Toast in a dry pan over medium heat for 2 to 3 minutes until golden at the edges. Watch it closely – it burns fast. Flaked coconut gives a chunkier topping.

Spelt Coconut Lime Drizzle Cake
Description
Wholegrain spelt keeps the crumb tender without making it heavy, while a hot lime sugar syrup soaks in straight from the oven for a clean, citrus-forward finish.
Ingredients
Cake batter
Lime drizzle syrup
Instructions
Prepare
- Heat the oven to 170 C / 340 F fan. Grease a 900 g loaf tin and line with baking parchment, leaving an overhang on the two long sides.
- Toast 15 g of coconut in a dry frying pan over medium heat for 2 to 3 minutes, stirring often, until golden at the edges. Set aside for topping.
Make the batter
- Whisk together the spelt flour, baking powder, bicarbonate of soda, salt, and caster sugar in a large mixing bowl until evenly combined.
- In a jug, whisk the eggs, coconut milk, melted coconut oil, lime zest, and lime juice until smooth.
- Pour the wet ingredients into the dry ingredients and stir with a silicone spatula until just combined - stop as soon as no dry streaks remain.
- Fold in the 40 g of untoasted desiccated coconut gently.
Bake
- Pour the batter into the prepared loaf tin and smooth the top level.
- Bake for 38 to 42 minutes, until the top is deep golden and a skewer inserted in the centre comes out with just a few moist crumbs.
Make the lime drizzle
- While the cake bakes, combine the lime juice and caster sugar in a small saucepan over low heat. Stir for 2 to 3 minutes until the sugar fully dissolves. Remove from heat and stir in the lime zest if using.
Drizzle and finish
- As soon as the cake comes out of the oven, use a skewer to poke about 15 holes across the surface, going about two-thirds of the way down.
- Pour half the warm lime syrup slowly and evenly over the hot cake. Wait 1 minute, then pour the remaining syrup over.
- Scatter the toasted coconut evenly across the top while the syrup is still slightly tacky.
- Leave the cake in the tin for 10 minutes, then lift out using the parchment overhang and cool on a wire rack. Slice once fully cool.

Note
Additional Notes
- Zest limes directly into the batter bowl to catch all the fragrant oils.
- Pour syrup in two stages - half first, wait 1 minute, then add the rest for even absorption.
- Toasted coconut burns quickly - pull it off heat as soon as edges turn golden.
- Rest the finished cake in the tin for 10 minutes before lifting out.
- Use room-temperature eggs for a smoother batter and even rise.
