Step 1: Prepare the Champagne Reduction
To intensify the champagne flavor in the frosting, you can reduce it first.
Pour ½ cup of champagne into a small saucepan and simmer over medium heat.
Let it cook until reduced to ¼ cup, about 6-8 minutes.
Set it aside to cool completely before adding it to the frosting.
Step 2: Make the Cupcakes
Preheat your oven to 350°F (175°C) and line a 12-cup muffin tin with cupcake liners.
In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.
In a large mixing bowl, cream the butter and sugar together until light and fluffy, about 2-3 minutes.
Beat in the eggs, one at a time, then mix in the vanilla extract.
Slowly mix in the dry ingredients, alternating with champagne and milk until just combined.
Gently fold in the chopped strawberries.
Divide the batter evenly among the cupcake liners, filling each about ⅔ full.
Bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean.
Let the cupcakes cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely.
Step 3: Prepare the Champagne Buttercream Frosting
In a large bowl, beat the butter until creamy, about 2 minutes.
Gradually add the powdered sugar, one cup at a time, mixing on low speed.
Pour in the cooled champagne reduction, vanilla extract, and a pinch of salt, then beat until smooth.
If the frosting is too thick, add 1 tablespoon of heavy cream to reach your desired consistency.
Step 4: Frost and Decorate
Pipe or spread the champagne buttercream frosting onto the cooled cupcakes.
Garnish with fresh strawberries and a sprinkle of edible gold flakes for an extra touch of elegance.
Serve and enjoy your delightful Strawberry Champagne Cupcakes!
