• Preheat the oven to 180C (350F) and grease an 8" x 4" loaf pan and set aside.

Prepare the Toppings

• Before you start, you need to mix the toppings.

  Apple Cinnamon Topping - mix the diced apple, granulated sugar and cinnamon together.

  Cinnamon Sugar - mix the cinnamon and sugar together.

  Glaze - mix the powdered sugar and milk together until it's smooth and glossy.

  Set all of these aside.

Quick Bread Batter

• In a medium sized bowl, add the egg, sugar and vanilla together and whisk until smooth and glossy.
• Now add the sourdough starter and vegetable oil to the mix and whisk until well combined.
• On top of the liquid ingredients, add the all purpose flour, baking powder and salt. Stir gently with a spatula until the wet ingredients and dry ingredients are well combined (just don't overmix).
• Now, take the loaf pan you greased earlier and add half the batter to the base of the pan. Spread it out using a spatula so it covers the base of the pan.

  On top of the cake batter, add half the apples and half the cinnamon sugar mixture.
• Now add the rest of the cake batter on top, followed by the rest of the apple mixture and cinnamon sugar mixture.
• Place into the oven and bake for 45 minutes at 180C (350F).
• The sourdough discard apple fritter cake is cooked through when a skewer comes out clean and the cinnamon sugar is a little crunchy on top.
• Once the cake has cooled slightly, drizzle over the glaze (do this while the cake is still in the pan). Allow the glaze to soak in a little before removing the cake from the pan. Make sure it cools fully before you slice it.
