Step 1

Preheat oven to 100°C. Combine the flour, caster sugar and cinnamon in a large bowl. Make a well in the centre. Whisk together the buttermilk, banana and egg in a jug. Gradually add the buttermilk mixture to the flour mixture, whisking constantly until a smooth batter forms. Cover with plastic wrap and set aside for 20 minutes to rest.

Step 2

Meanwhile, combine the coconut milk, brown sugar and lime leaves in a medium saucepan over high heat. Bring to the boil. Cook, stirring occasionally, for 5 minutes or until the sauce thickens slightly. Remove from heat and discard the lime leaves. Transfer to a jug.

Step 3

Brush a large non-stick frying pan with a little of the melted butter to lightly grease and heat over medium heat. Pour two 60ml (1/4-cup) quantities of batter into the pan, allowing room for spreading. Cook for 1 1/2-2 minutes or until bubbles appear on the surface and pancakes are golden underneath. Turn and cook for a further 1 minute or until golden. Transfer to a heatproof plate and cover loosely with foil. Place in oven to keep warm. Repeat, in 5 more batches, with the remaining melted butter and batter, reheating the pan between batches.

Step 4

Divide the hotcakes among serving plates. Drizzle over the kaffir lime syrup and top with extra lime leaves. Serve immediately with lime wedges and ice-cream, if desired.
