New Years Eve Champagne Cupcakes

I love champagne.  Last year I found a recipe for champagne cupcakes and have been wanting to make it ever since.  The stars aligned today, and I baked up these beauties in my kitchen this afternoon.

There are quite a few steps, so these are a little time consuming.  The steps are easy, and the cupcakes are delicious!

Champagne Cupcakes
yield 18 cupcakes
1/2 cup butter softened
1 cup granulated sugar
2 eggs
1 tsp vanilla
1 3/4 cups flour
1/2 tsp baking soda
1/4 tsp baking powder
1/4 tsp salt
1/2 cup sour cream
1/2 cup champagne

Preheat oven to 350 degrees.

In the bowl of a stand mixer fitted with the paddle attachment, cream together butter and sugar until light and fluffy.  Add eggs one at a time beating well after each addition. Add vanilla and mix. Whisk together flour, baking soda, baking powder and salt, set aside.  in a medium sized bowl, whisk together 1/2 cup champagne and 1/2 cup sour cream (mixture will fizz and bubble a little).  Add flour and champagne mixture alternately, beginning and ending with flour.  Batter will be thick.

Fill cupcake papers with 1/4 cup level measures of batter.  Bake for 17-22 minutes.  Set aside.


Champagne Pastry Creme Filling

1/2 cup heavy cream, divided
1/2 cup champagne
2 tbsp cornstarch 
5 tbsp granulated sugar
1 whole egg
2 egg yolks
2 tbsp unsalted butter
1 tsp vanilla

In a medium bowl, whisk cornstarch in 1/4 cup of heavy cream. Combine the remaining heavy cream, sugar and 1/2 cup champagne in a saucepan; bring to a boil then remove from heat.

Beat the whole egg and egg yolks into the cornstarch/heavy cream mixture.  Pour 1/3 of boiling champagne mixture into the egg mixture, whisking constantly so the eggs do not cook.  Return the remaining champagne/heavy cream mixture to a boil.  Pour in the hot egg mixture in a stream, whisking constantly until the mixture thickens.  Remove from heat and beat in the butter and vanilla.  

Cut a divot into the top of each cupcake and fill with pastry cream.


Champagne Frosting
1 cup plus 1 tbsp. champagne
2 sticks of butter softened
2 1/2 cups confectioners' sugar

Place 1 cup of champagne in a small saucepan.  Simmer over medium-high heat until reduced to 2 tablespoons.  Transfer to a small bowl or condiment cup and allow to cool.

In the bowl of a stand mixer fitted with the whisk attachment, cream softened butter and powdered sugar together.  Once the frosting is thick and fluffy, pour in the reduced 2 tbsp. champagne plus  1 tbsp. champagne from the bottle and mix well.

Frost the cream-filled cupcakes and decorate with sprinkles of your choice.
