(Makes 1 cake): To make the topping: Finely slice the oranges and satsumas into rounds.
Step #2
Dissolve the caster sugar in the water and bring the syrup to a boil. Add the orange and satsuma slices and simmer for 15-20minutes, turning half way until the slices are tender but still holding shape.
Step #3
Cool, then transfer onto a cooling wire in a single layer. To make the cake:: Place the cake mix, ground almonds, orange juice, Greek yoghurt and olive oil into a bowl and beat for 1-2 minutes to form a smooth batter.
Step #4
Place in a well greased and lined 9” cake tin. Bake in a preheated oven 180°C (°F) Gas Mark 4 for 45-50 minutes until firm to the touch.
Step #5
To make the syrup:: Place the orange juice and caster sugar into a small saucepan for the syrup and heat gently until all the sugar has dissolved. Skewer the cake all over and douse with the orange syrup.
Step #6
