• Heat your oven to 350°F (175°C). Prepare a 10-inch round pan by greasing and dusting with flour (if needed).
• In a bowl, sift together the flour, baking powder, and salt.
• In another large bowl, beat the sugar and butter until smooth and fluffy. Slowly pour in the champagne while mixing.
• Whip egg whites in a clean bowl until stiff peaks form. Gently fold them into the wet mixture.
• Slowly fold the dry ingredients into the wet mixture, being careful not to overmix.
• Pour the batter into the prepared pan. Bake for 30–35 minutes. Check with a toothpick—if it comes out clean, it’s done
• Let the cake cool in the pan for 15–20 minutes, then move it to a wire rack to cool completely.

Decoration and Frosting Ideas

• Use whipped cream for a light and airy texture
• Try cream cheese frosting for a rich and slightly tangy flavor
• Go fancy with white chocolate ganache for a glossy, luxurious finish
• Add a touch of glam with rose gold or ivory edible glitter spray
• For a pop of color, use pink edible glitter or food spray
• Want a pattern? Chill the cake, then apply whipped cream in a zig-zag design
• Use tools like a turning table, spatula, and scraper for smooth, professional results
