In a bowl, combine the lemon juice, peeled and chopped apples, and brown sugar. Cover with plastic wrap, poke it 2 or 3 times, and microwave on high for 5 minutes.
Preheat the oven.

Whisk together the olive oil and sugar. Add the eggs and sifted flour with baking powder.

Add the apples to the mixture and pour into a well-greased baking pan.

Make the crumble:
In a bowl, combine the flour, brown sugar, and cinnamon. Add the olive oil and mix with your hands until you get a crumbly texture. Stir in the chopped almonds, mix, and sprinkle over the batter in the pan.
Bake in the preheated oven at 350°F (180°C) for 60 minutes or until a toothpick inserted in the center comes out clean.

Enjoy!
