Apple Cinnamon Muffins with Crumble

Instructions:

1. Preheat your oven to 375°F (190°C). In a medium bowl, whisk together the 1/2 cup flour, brown sugar, and 1 tsp cinnamon. Use your fingertips or a fork to rub the cold butter into the mixture until it resembles coarse sand with some pea-sized lumps. Set aside in the fridge.
2. In a large bowl, whisk together 1 1/2 cups flour, baking powder, 1 tsp cinnamon, and salt.
3. In a separate jug, beat the egg, then stir in the applesauce, maple syrup, milk, and vanilla until smooth.
4. Pour the wet ingredients into the dry flour mixture, stirring with a spatula only until no streaks of flour remain.
5. Gently fold in the diced apples using a spatula until the apple chunks are evenly distributed, ensuring the batter remains slightly lumpy.
6. Spoon the batter evenly into a lined 12-cup muffin tin. Top each muffin with a generous pinch of the chilled crumble.
7. Bake for 18-22 minutes, or until a toothpick inserted into the center comes out clean and the tops are golden brown.
