Preheat the oven to 350℉ and line an 8" round pan with parchment paper.
Combine all the crumble ingredients except for the butter. Mix in the melted butter until well combined—it should clump together if pressed. Set aside.
½ cup all purpose flour, ⅓ cup rolled oats, 4 tablespoon brown sugar, ⅛ teaspoon salt, ¼ teaspoon ground cinnamon, 4 tablespoon unsalted butter, melted
In a large bowl beat together the sugar, butter and oil until light and pale.
¾ cup brown sugar, ¼ cup unsalted butter, melted, ¼ cup neutral oil
Crack in both eggs and whisk until combined. Beat in the yogurt and milk.
2 large eggs, ⅓ cup plain yogurt, 2 tablespoon milk
Set this mixture aside and peel and chop the apples. Toss with lemon juice.
2 large apples, sliced or chopped, 1 tablespoon lemon juice
Now toss the apples with brown sugar, cinnamon, salt, ground ginger and nutmeg. Set aside.
¼ cup brown sugar, ½ teaspoon ground cinnamon, ⅛ teaspoon ground nutmeg, ⅛ teaspoon ground ginger, pinch salt
Add the flour, baking powder, baking soda, cinnamon, nutmeg, salt and ground ginger to the wet ingredients and gently mix to combine using a spatula. Make sure not to over mix the batter.
1¼ cup all purpose flour, 1 teaspoon baking powder, ¼ teaspoon baking soda, ¼ teaspoon salt, 1 teaspoon ground cinnamon, ¼ teaspoon ground nutmeg
Pour and spread the batter into the prepared pan. Evenly cover with the apples and then the crumble. Bake at 350 for about 45-55 minutes or until a toothpick inserted comes out clean or with a few crumbs. Let the cake cool in the pan for about 15 minutes and then transfer to a cooling rack to cool completely.
