Creating Peaches & Cream Cupcakes can be straightforward if you follow these simple steps:

1. Preheat your oven to 350°F (175°C). Line a muffin tin with cupcake liners.
2. Mix Dry Ingredients: In a large bowl, whisk together the flour, baking powder, baking soda, and salt.
3. Cream Butter and Sugar: In another bowl, beat the softened butter and granulated sugar until light and fluffy.
4. Add Eggs and Vanilla: Incorporate the eggs and vanilla extract into the butter mixture, mixing until well combined.
5. Combine Wet Ingredients: Stir in the sour cream until the mixture is smooth.
6. Combine Mixtures: Gradually add the dry ingredients to the wet ingredients, stirring gently until just combined.
7. Fold in Peaches: Gently fold in the diced peaches, being careful not to overmix.
8. Fill Cupcake Liners: Divide the batter evenly among the prepared cupcake liners, filling each about two-thirds full.
9. Bake: Place in the preheated oven and bake for 20-25 minutes or until a toothpick inserted in the center comes out clean.
10. Cool: Remove from the oven and allow the cupcakes to cool in the pan for 10 minutes. Then, transfer them to a wire rack to cool completely.
11. Prepare Frosting: In a separate bowl, beat the softened cream cheese until smooth. Gradually add the powdered sugar and mix until well combined. Stir in vanilla extract.
12. Frost the Cupcakes: Once the cupcakes are completely cool, generously frost each cupcake with the cream cheese frosting.
13. Garnish: Top each cupcake with additional diced peaches and a mint leaf if desired.

These steps will guide you in creating these incredible cupcakes effortlessly.
