Preparation Steps
- Preheat the oven to 425°F. Line muffin tins with paper liners and set aside.
- In a medium bowl, combine the flour, baking powder, baking soda, apple pie spice, and salt. Whisk together to combine.
- In a large bowl, use a hand mixer to beat together the butter, oil, granulated sugar, and brown sugar until smooth and slightly fluffy.
- Add the eggs and vanilla, mixing until fully incorporated.
- Pour in the buttermilk and mix until just combined. The batter may look slightly curdled at this point; this is normal.
- Add the flour mixture to the wet ingredients and mix until just combined. Do not overmix. Set aside.
- In a small bowl, toss the finely diced apples, granulated sugar, and apple pie spice. Stir until the apples are well coated.
- Gently fold the apple mixture into the muffin batter using a spatula, being careful not to overmix.
- Divide the batter evenly among the muffin cups, filling each one to the top.
- In a small bowl, mix together the granulated sugar and ground cinnamon for the topping.
- Brush the tops of each unbaked muffin generously with melted butter, then sprinkle the cinnamon-sugar mixture evenly over the tops.
- Bake the muffins for 18–20 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs but no wet batter.
- Let the muffins cool in the pan for 5–10 minutes, then transfer them to a wire rack to cool completely.
