Orange Lightning Cake
We call it a lightning cake because you make it in a flash. It’s so quick and simple and yet it has an amazing flavour, like something your grandmother might have made, that has everyone coming back for seconds. You can use sultanas or raisins.
1 whole orange, unpeeled
1 tsp baking soda
1/2 cup water
125 g butter, softened
1 cup sugar
1 tsp vanilla extract
2 cups plain flour
1 cup sultanas, or raisins
1/2 cup walnuts, chopped (optional)
Preheat oven to 160°C fanbake.
Grease a 20cm-diameter cake tin and line the base with baking paper.
Cut the orange into quarters, remove the seeds and whizz in a food processor until finely chopped.
Dissolve baking soda in water and add to the food processor with butter, sugar, eggs, vanilla and flour.
Whizz to combine.
Add sultanas or raisins and walnuts, if using, and stir with a spoon or pulse several times to just combine (don’t whizz them or they will break up).
Pour into prepared cake tin and bake until a skewer inserted into the centre comes out clean (about 1 hour).
Orange Lightning Cake will keep in an airtight container for up to a week or can be frozen.
