I created a recipe for strawberry champagne cupcakes out of my love for champagne, berries, white cake, and white buttercream frosting (I think the perfect cupcake is white cake with white icing). However, I wanted to infuse flavor into plain white cake and since I had an abundance of strawberries, I started to experiment with them. Also, what's better with strawberries than champagne? Combing the 2 was a no brainer. I've made them several times with rave reviews so far and I think I've just about perfected the recipe. The champagne flavor is more of a fruity flavor (you won't taste the bubbles) and it's incredibly good.
The cupcakes have 3 parts to them, but they're all easy and you can make the strawberry sauce in advance. You'll also have plenty leftover sauce and it's great over ice cream, berries, and it freezes beautifully.
Here's my recipe:
For the cupcakes:
1 1/3 cups all purpose flour
1 teaspoon baking powder
1/2 teaspoon salt
1/3 cup champagne/prosecco/sparkling wine (make sure it's a good one and something you would want to drink- the better the quality, the better the cupcakes will be)
3 XL egg whites
2 tablespoon sour cream
1 1/2 teaspoon pure vanilla extract
1 stick unsalted butter at room temperature
1 cup sugar
Preheat the oven to 350
Sift flour, baking soda, and salt in a bowl and set aside
In another bowl (or measuring cup) combine champagne, egg whites, sour cream, and vanilla
Whisk together until sour cream is incorporated and there's no lumps
Using an electric or hand held mixture, cream butter and sugar at least 5 minutes, until light and fluffy
Add 1/3 of the flour mixture and mix until incorporated
Add 1/2 of the wet mixture
Add another 1/3 of the flour mixture
Add last 1/2 of the wet mixture
Add last 1/3 of the flour and mix until just combined (do not overmix!)
Divide the batter among 12
cupcake paper liners
Bake 15-18 minutes, until a toothpick comes out clean
Cool in the pan for 5 minutes
Remove from the pan and place cupcakes on a cooling rack until completely cooled (you can also refrigerate them- the colder they are the easier they are to cut)
Strawberry Sauce:
1 1/2 pounds fresh or frozen strawberries, hulled and sliced
1/4 cup sugar
2-3 tablespoons water
1 jar (12 oz.) strawberry jam
Cook berries, sugar, and water (start with 2 tablespoons and add more if the sauce is too thick) in a medium saucepan over medium high heat
Bring to a boil and stir so it doesn't burn
Cook until berries are softened and sugar is dissolved
Off the heat, add strawberry jam and puree (with blender, food processor, or immersion blender)
Taste and add more sugar if needed
Cool sauce
When cupcakes and sauce are cooled, use a small knife to cut a fairly large hole from the center of cupcake (reserve the top)
Fill the hole with strawberry sauce (about 1-2 tablespoons)
Place the top of the hole back in cupcake
Champagne frosting:
3 cups powdered sugar
1 stick unsalted butter at room temp.
4-5 tablespoons champagne/prosecco/sparkling wine
2 teaspoons pure vanilla extract
Beat powdered sugar, butter, vanilla, and 2 tablespoons of champagne with an electric or hand held mixer
Add more champagne as needed until frosting is smooth and spreadable, but not thin (if it's too thin, add more powdered sugar. If it's too thick, add more champagne)
Generously frost each cupcake with the icing and garnish with a strawberry
Variation: This recipe can be made by using a 1/2 stick of butter and a 1/2 cup applesauce in place of the whole stick of butter in the cupcake recipe. Also, fat free sour cream is perfectly fine.
Note: You can refrigerate these cupcakes (so the frosting doesn't melt), but bring them to room temp. before serving.
Also, the longer the cupcakes sit, the more you'll taste the champagne- I make them the day ahead and they're even better on the 2nd day. Enjoy!
