Creating the amazing Peach Pie Cupcakes can be easy if you follow these steps:

1. Preheat Your Oven: Preheat your oven to 350°F (175°C). Line a muffin tin with cupcake liners.
2. Prepare the Peaches: In a medium bowl, combine the diced peaches with lemon juice and ground cinnamon. Set aside to marinate.
3. Mix Dry Ingredients: In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.
4. Cream Butter and Sugar: In a large bowl, cream together the softened butter and granulated sugar until light and fluffy.
5. Add Eggs and Vanilla: Beat in the eggs one at a time, followed by the vanilla extract, mixing until well combined.
6. Combine Mixtures: Gradually add the dry ingredients to the butter mixture, alternating with the buttermilk. Mix until just combined.
7. Fold in Peaches: Gently fold the marinated peaches into the batter until evenly distributed.
8. Prepare Crumble Topping: In a small bowl, mix the brown sugar, rolled oats, flour, and cubed cold butter. Use a fork or your hands to combine until crumbly.
9. Fill Cupcake Liners: Spoon the batter into the cupcake liners, filling each about two-thirds full. Top each cupcake with a generous sprinkle of crumble topping.
10. Bake: Place the muffin tin in the preheated oven and bake for 20-25 minutes, or until a toothpick inserted in the center comes out clean.
11. Cool: Remove the cupcakes from the oven and let them cool in the tin for 10-15 minutes before transferring them to a wire rack to cool completely.

Once you’ve followed these steps, you’ll have a delightful batch of Peach Pie Cupcakes ready to enjoy!
