Prepare Cake Pans
- Preheat your oven to 350°F (177°C) and line four 6-inch round cake pans with parchment paper.
Make Batter
- Whisk together the dry ingredients: cake flour, baking powder, baking soda, and salt.
- Cream softened unsalted butter until light and fluffy, then gradually add granulated sugar.
- Mix in egg whites, vegetable oil, and vanilla extract, followed by alternating the dry mixture with buttermilk.
Tint Batter
- Divide batter into four bowls and add pink food coloring to achieve varying shades.
Bake
- Scoop batters into prepared pans, starting with the darkest shade at the bottom. Bake for 30–35 minutes.
- Cool cakes completely on wire racks.
Prepare Buttercream
- Whip room-temperature unsalted butter until creamy. Gradually add powdered sugar, mixing well.
- Add whole milk and vanilla extract until the frosting is smooth and spreadable.
Assemble Cake
- Once cakes are cool, level tops if necessary. Layer the cakes from darkest to lightest with buttercream in between.
Frost Cake
- Crumb coat the cake, refrigerate for 15 minutes, and then use the remaining buttercream to frost the cake.
Decorate
- Pipe a swirl border on top and add pink ombre sprinkles for decoration.
