Step 1

Preheat oven to 180 C (350 F) standard / 160 C (320 F) fan-forced. Grease and line an 8 or 9 inch round cake tin with baking or parchment paper.

Step 2

In a large mixing bowl, add flour, baking powder, baking soda and sugar. Add chopped apple and stir briefly to combine.

Step 3

In a separate bowl, add eggs, vanilla, oil and yoghurt. Whisk briefly just to break up the egg yolks.

Step 4

Add wet ingredients to dry ingredients and gently mix with a wooden spoon until combined – but be careful not to over mix. Spoon batter into prepared tin.

Step 5

To make cinnamon topping, combine cinnamon, sugar and butter. Mix together until lumpy and wet. Sprinkle over cake batter.

Step 6

Bake cake for approximately 30-35 minutes or until a skewer inserted into the middle comes out clean. Transfer cake to a wire rack to cool completely.

Step 7

To make the glaze, mix together sugar and 1 tablespoon of milk. Stir until smooth. If the glaze is too thick, add an extra tablespoon of milk. Drizzle glaze all over the cake.
