Beat the eggs and oil, milk, and vanilla extract in a large bowl until well integrated. I do it by hand, but you can use an electric mixer. A stand mixer I think is too much as it does not require a lot of beating, but you can (with the paddle attachment).
Add white and brown sugars, and mix for 1 minute.
Sift the dry ingredients (flour, cinnamon, baking powder, baking soda, and salt) into a medium bowl.
Add the wet ingredients to the dry ones and combine well. Don't overmix and use the lowest speed if using an electric mixer. I use a hand whisk.
Fold in the diced apples and stir to combine.
Pour the batter into the prepared pan, and smooth the top.
Sprinkle the crumble on top, covering the batter.
Bake for about 60 minutes, or until a cake tester or toothpick inserted in the center comes out clean.
Cool for 20 minutes on a wire rack and carefully run a smooth-bladed knife around the sides to ensure no batter is stuck. Cool completely and then lift the whole bread with the help of the parchment paper.
Store leftovers at room temperature for 2 days or in the fridge for a week. Always well covered with plastic wrap or in an airtight container to prevent dryness.
