1. Preheat the oven to 170C/150C fan forced. Grease and line the base and side of a deep, round 20cm (base measurement) cake pan with baking paper. 2. Place the almond meal, cornflour, sugar, coconut, millet flour, sesame seeds and baking powder in a large bowl. Make a well in the centre.Add coconut oil, eggs, lemon rind, 60ml (1 ⁄4 cup) lemon juice, vanilla and 60ml (1 ⁄4 cup) water. Stir with a large metal spoon until just combined. Pour the mixture into the prepared pan. Smooth the surface. Use the pepitas and almonds to decorate the top of the cake in floral patterns. Bake cake for 40-45 minutes or until a skewer inserted in the centre comes out clean. Cool in pan for 10-15 minutes, then turn onto a wire rack set over a baking tray. 3. For the syrup, place sugar, lemon juice and 80ml (1 ⁄3 cup) water in a small pan. Stir over low heat until sugar dissolves. Increase heat and simmer for 3-5 minutes or until the syrup thickens slightly. 4. Pour the syrup over the warm cake. Decorate with lime pearls and flower petals, if using. Serve with coconut yoghurt, if you like.
