Follow these simple steps to create the amazing Peach Bellini Cupcakes:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and line a cupcake tin with paper liners.
2. Cream the Butter and Sugar: In a large bowl, cream together the softened butter and granulated sugar until light and fluffy.
3. Add Eggs: Beat in the eggs one at a time, mixing well after each addition.
4. Mix in Wet Ingredients: Add the peach puree, whole milk, prosecco, and vanilla extract. Mix until well combined.
5. Combine Dry Ingredients: In a separate bowl, sift together the all-purpose flour, baking powder, and salt.
6. Combine Mixtures: Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Be careful not to overmix.
7. Fill Cupcake Liners: Divide the batter evenly among the prepared cupcake liners, filling each about two-thirds full.
8. Bake: Place in the preheated oven and bake for 20-25 minutes or until a toothpick inserted in the center comes out clean.
9. Cool: Remove from the oven and let the cupcakes cool in the tin for 5 minutes, then transfer to a wire rack to cool completely.
10. Prepare Frosting: In a medium bowl, beat the softened butter until creamy. Gradually add the powdered sugar, prosecco, vanilla extract, and salt. Beat until light and fluffy.
11. Frost the Cupcakes: Once the cupcakes are completely cool, frost them generously with the prosecco frosting.
