Ingredients:
- ½ cup (100g) all-purpose flour, plus extra for dusting
- ¼ cup (50g) packed light brown sugar
- ¼ teaspoon ground cinnamon
- ¼ cup (57g) cold unsalted butter, cut into small cubes
- 1 ¾ cups (220g) all-purpose flour
- ¾ cup (150g) granulated sugar
- 2 teaspoons baking powder
- ½ teaspoon ground cinnamon
- ¼ teaspoon ground nutmeg
- ¼ teaspoon salt
- ½ cup (120ml) milk
- ⅓ cup (80ml) vegetable oil
- 1 large egg
- 1 teaspoon vanilla extract
- 2 medium apples (such as Gala or Honeycrisp), peeled, cored, and diced
Instructions:
- Prepare the Crumble Topping: In a medium bowl, combine flour, brown sugar, and cinnamon. Cut in cold butter using a pastry blender or your fingers until the mixture resembles coarse crumbs. Refrigerate until ready to use.
- Preheat Oven and Prepare Muffin Tin: Preheat oven to 375°F (190°C). Line a 12-cup muffin tin with paper liners or grease well.
- Combine Dry Ingredients: In a large bowl, whisk together flour, sugar, baking powder, cinnamon, nutmeg, and salt.
- Combine Wet Ingredients: In a separate bowl, whisk together milk, oil, egg, and vanilla extract.
- Combine Wet and Dry Ingredients: Pour the wet ingredients into the dry ingredients and stir until just combined. Do not overmix – a few lumps are okay!
- Fold in Apples: Gently fold the diced apples into the batter.
- Fill Muffin Cups: Fill each muffin cup about ¾ full.
- Top with Crumble: Sprinkle the crumble topping evenly over the muffins.
- Bake: Bake for 20-25 minutes, or until a wooden skewer inserted into the center comes out clean. The muffins should be golden brown on top.
- Cool: Let the muffins cool in the muffin tin for a few minutes before transferring them to a wire rack to cool completely.
