Take your softened butter, pop it in a mixing bowl, and beat it until it’s super fluffy—this should take about 2-3 minutes. Add the powdered sugar little by little on low until it looks crumbly. Mix in your pink champagne, vanilla (if you’re using it), and a pinch of salt, then crank up the speed to medium-high and let it whip for around 3-5 minutes until it’s airy and smooth. Add some pink color if that’s your thing.

Turn your oven on to 350°F to preheat. Prepare three 6-inch round cake pans with parchment circles and either spray some baking spray or carefully butter and flour them.

In a medium-sized bowl, whisk together your flour, baking powder, and salt until it’s all evenly mixed.

Use a mixer to cream your softened butter and sugar together for about 2-3 minutes until it’s light and fluffy. Stir in the vanilla, then add in your egg whites, one at a time. Make sure everything is mixed well and scrape the sides of the bowl when you need to.

Starting and ending with the dry mix, alternate adding the flour mixture and the champagne to the butter mixture like this: flour, champagne, flour, champagne, flour. Mix just enough to combine everything. If you like, add pink gel food coloring right after the second addition of flour.

Evenly divide the batter into the prepared cake pans, smooth out the tops, and bake for about 25-30 minutes. You’ll know they’re ready when a toothpick comes out with a few moist crumbs stuck to it. Let them cool in the pans for about 10 minutes, then move the layers to a wire rack to cool completely.

Once all the cake layers are completely cool, stack them neatly with the champagne buttercream in between each layer. If you’re feeling creative, drizzle with white chocolate, top with chocolate-dipped strawberries, or use champagne marshmallows to really impress!
