Mix the brown and white sugar with the oil.

Beat well, then add the honey, vanilla extract, and eggs one at a time, beating continuously. Add the orange zest.

In a separate bowl, mix the dry ingredients (flour, baking powder, cinnamon, corn starch) and sift them over the wet ingredients.

Finally, add the milk and gently mix with a spatula.

To make the crumble, mix the butter, sugar, and flour with your hands until it forms a sandy texture.

In an 18 cm baking mold, pour in the cake mixture, then sprinkle the crumble mixture on top, followed by the apple slices.

Bake at 180°C (350°F) for 50 minutes or until a toothpick comes out clean.

Let the cake cool slightly before serving. Enjoy!
