Ingredients
Method
Cupcakes
- Line a muffin tin with cupcake liners and preheat the oven to 325°F.
- Using a handheld or a stand mixer, cream together the butter and the sugar at medium speed for 2-3 minutes until light and fluffy.
- Add the egg whites and the additional whole egg and mix until well combined.
- In a small bowl, combine the flour, baking powder, and salt.
- With the mixer on low speed, add half of the flour mixture, mixing until just combined.
- Mix in the champagne until well incorporated, then mix in the final half of the flour mixture.
- Fill cupcake liners ~¾ full with the cake batter. Bake for 20 minutes on the lower rack of your oven or until a toothpick inserted in the center comes out clean. Let cool completely before frosting.
Strawberry Swiss Meringue Buttercream
- Whisk together the 5 egg whites and sugar in your mixing bowl and place over a pot of simmering water. Be careful your bowl doesn't touch the water.
- Whisk frequently and cook until the mixture reaches 165°F on a candy thermometer.
- Using a whisk attachment, beat the egg white mixture on high speed until the mixing bowl is no longer warm to the touch (this usually takes me around 20 minutes).
- Switch to a paddle attachment and add in the butter on low speed until just combined. If your mixture is too soupy, place it in the refrigerator for 5-10 minutes then gently mix again for a couple seconds on low speed.
- Mix in the crushed freeze-dried strawberries.
- Fill a piping bag with the frosting and frost the cupcakes to your desired style. Add a sliced strawberry on top for a garnish.
Notes
*If you can't find strawberry champagne, you can use a sparkling moscato or another sparkling wine with tasting notes of strawberry.
