Baking these Spiced Peach Vanilla Cupcakes is a simple process. Just follow these easy steps:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C). Line a cupcake tin with paper liners.
2. Mix Dry Ingredients: In a medium bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, and nutmeg.
3. Cream Butter and Sugar: In a large mixing bowl, beat the softened butter and granulated sugar together until light and fluffy.
4. Add Eggs and Vanilla: Add the eggs, one at a time, mixing well after each addition. Then, mix in the vanilla extract.
5. Combine Mixtures: Gradually add the dry ingredients to the wet ingredients, alternating with the milk. Mix until just combined.
6. Fold in Peaches: Gently fold in the diced peaches, ensuring they are evenly distributed throughout the batter.
7. Fill Cupcake Liners: Divide the batter evenly among the cupcake liners, filling each about two-thirds full.
8. Bake: Place the cupcake tin in the preheated oven and bake for 20-25 minutes, or until a toothpick inserted in the center comes out clean.
9. Cool the Cupcakes: Remove the cupcakes from the oven and allow them to cool in the tin for about 10 minutes. Then transfer them to a wire rack to cool completely.
10. Prepare the Frosting: While the cupcakes cool, make the vanilla buttercream frosting. In a mixing bowl, beat the softened butter until creamy. Gradually add the powdered sugar, mixing on low speed. Once combined, add the vanilla extract and heavy cream. Beat on high until the frosting is fluffy and smooth. Add a pinch of salt to taste.
11. Frost the Cupcakes: Once the cupcakes are completely cool, use a piping bag or a knife to frost the tops with the vanilla buttercream.
