Preheat your oven to 350 degrees Fahrenheit. Line a cupcake tin with paper liners.

In a medium bowl, whisk together the flour, sugar, brown sugar, baking powder, cinnamon and salt. Add the eggs, milk, oil, and vanilla and mix until smooth. Stir in the apples. Fill cupcake liners 3/4 the way with batter.

Prepare the crumb topping. Combine all ingredients in a bowl, using a fork or your fingers to make crumbs. Sprinkle over the batter.

Bake for 25 minutes. Allow to cool and enjoy!
