Cinnamon Topped Apple Cake

Apple cake
210 grams (1 and 1/2 cups) plain flour or all purpose flour
2 teaspoons baking powder
1/2 teaspoon baking soda
1/4 teaspoon salt
150 grams (3/4 cup) caster sugar or granulated sugar
1 cup (approximately 1 large) red apple, peeled and roughly chopped
2 large eggs
1 teaspoon vanilla extract
120 ml (1/2 cup) vegetable oil
120 ml (1/2 cup) Greek yogurt

Cinnamon topping
50 grams (1/4 cup) caster sugar or granulated sugar
1 teaspoon ground cinnamon (pie spice)
1 tablespoon butter, melted

I doubled sugar and cinnamon - too soupy as written. Amount would only provide a sparse topping.

Sugar glaze
30 grams (1/4 cup) icing sugar or powdered sugar, sifted
1–2 tablespoons milk

1/8t vanilla

INSTRUCTIONS

1. Preheat oven to 180 C (350 F) standard / 160 C (320 F) fan-forced. Grease and line an 8-inch round cake pan with baking or parchment paper. (I used an 8x8 square pan)
2. In a large mixing bowl, add flour, baking powder, baking soda, salt and sugar. Add chopped apple and stir briefly to combine.
3. In a separate bowl, add eggs, vanilla, oil and yoghurt. Whisk briefly just to break up the egg yolks.
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.
5. To make cinnamon topping, combine cinnamon, sugar and butter. Mix together until lumpy and wet. Sprinkle over cake batter.
6. Bake cake for approximately 30-35 minutes or until a skewer inserted into the middle comes out clean. (8x8 square needed 45-50 minutes) Transfer cake to a wire rack to cool completely. (cooled in pan, when cooled enough to touch pan I lifted it out of pan long enough to remove parchment paper then returned it to the pan)
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. 

May try adding a bit of cinnamon to the dry ingredients to give the cake a bit more flavor. 

Topping worked well with changes I made. 

Has a coffee cake vibe to it, tasty and moist.
