A light and moist champagne cake infused with sparkling wine and topped with a bright, tangy orange buttercream frosting. Perfect for celebrations and easy to make with simple pantry ingredients.
Do not rush the creaming process; whip butter and sugar until fluffy to trap air for a tender crumb. Fold dry ingredients gently to avoid toughening the cake. Use dry or brut champagne for subtle flavor without sweetness. Chill and re-whip frosting if too soft. Cool cake completely before frosting to prevent melting buttercream. Frosting can be made a day ahead and stored in fridge.
