Preheat oven to 375F. Line muffin tins with baking cups or grease tins with cooking spray and set aside.

Mix flour, baking powder, baking soda and salt together in a medium bowl. In a separate bowl, beat together butter, sugar and eggs until smooth. Add in vanilla and stir until incorporated. Stir in apples, and carefully fold in the flour mixture.

In a small bowl, mix brown sugar, flour and cinnamon. Cut in butter until mixture forms coarse crumbs. If you have major OCD like me, use a 3 tablespoon cookie scoop to fill your muffin tins. But if you’re like the normals of the world, just fill the tins 2/3rds of the way full and sprinkle with crumb topping mixture.

Bake for 20 minutes or until they are lightly browned.

Cool slightly and serve warm.

This recipe makes approx. 12 muffins, and these freeze exceptionally well!
