Follow these straightforward steps to create your delicious Peach Cobbler Cupcakes:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Line a standard muffin tin with paper liners.
2. Mix Dry Ingredients: In a large bowl, whisk together flour, granulated sugar, baking powder, baking soda, and salt.
3. Combine Wet Ingredients: In another bowl, cream together the softened butter and granulated sugar until fluffy. Add the eggs, vanilla extract, and buttermilk; mix until well combined.
4. Combine Mixtures: Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix.
5. Prepare Peaches: Gently fold in the diced peaches along with the ground cinnamon and nutmeg.
6. Fill Muffin Tin: Divide the batter evenly among the muffin cups, filling each about two-thirds full.
7. Prepare Topping: In a small bowl, mix together brown sugar, rolled oats, flour, and melted butter until crumbly. Sprinkle the topping evenly over each cupcake.
8. Bake: Place the muffin tin in the preheated oven and bake for 18-22 minutes or until a toothpick inserted into the center comes out clean.
9. Cool: Remove the cupcakes from the oven and let them cool in the tin for 10 minutes. Transfer to a wire rack to cool completely.
10. Optional Glaze: For an extra touch, drizzle with a simple icing made from powdered sugar and milk.
