Preheat the oven to 350 degrees.
Wash and peel the apples. Then slice them. I cut them thin but feel free to leave them a little chunkier or cut them into cubes. Just make sure they aren't more than 1 inch thick.
Add the lemon juice, 1/4 cup brown sugar, 1/4 cup of sugar and 1/2 Tbsp. cinnamon to the apples and then mix. You can do this in the same pan you're going to cook them in if you like. Refrigerate once mixed for 30 minutes.
In a separate bowl, mix together the flour, the rest of the sugar, the rest of the brown sugar, baking powder, 1/2 Tbsp. cinnamon and nutmeg. Whisk well with a metal whisk to ensure the baking powder mixes.
Then mix in the egg and milk. The mix will seem a little dry but keep mixing until its well combined.
When the apples are done in the fridge, room them and add to the baking dish (if you didn't mix them in the baking dish). Then drop the flour mixture onto the apples throughout the baking dish.
Slice the butter and layer it on top of the dough mix.
Lastly, bake for 30-40 minutes. Let cool for about 10 minutes and then serve with a scoop of ice cream.
