- Separate eggs; discard 4 of the yolks. Allow remaining yolks, the egg whites, and butter to stand at room temperature for 30 minutes. Meanwhile, generously grease twenty-four to thirty 2 1/2-inch muffin cups. If using vanilla bean, use a sharp knife to scrape seeds from vanilla bean halves; set seeds aside. In a medium bowl stir together flour, baking powder, and salt.
- Preheat oven to 350 degrees F. In a large mixing bowl beat egg whites with an electric mixer on high speed until stiff peaks form (tips stand straight); set aside.
- In another large mixing bowl beat butter on medium to high speed for 30 seconds. Gradually add granulated sugar, about 1/4 cup at a time, beating about 2 minutes or until light and fluffy. Beat in the reserved egg yolks and the vanilla seeds or vanilla extract. Alternately add flour mixture and champagne to butter mixture, beating on low speed after each addition just until combined. Fold half of the beaten egg whites into the batter to lighten; fold in remaining beaten egg whites. Spoon batter into prepared muffin cups, filling each about three-fourths full.
- Bake about 15 minutes or until a wooden toothpick inserted in centers comes out clean. Cool in pans on a wire rack for 5 minutes. Remove cupcakes from muffin cups. Cool completely on wire rack.
- Place jam in a pastry bag fitted with a round tip. Insert the tip into the top of each cupcake. Squeeze about 1 teaspoon of the jam into the center of each cupcake. Spread or pipe Champagne Butter Frosting on cupcakes. Decorate with jimmies, coarse sugar, and/or other white sprinkles.
