Can I make this cake ahead of time?
Yes. Bake and cool the layers completely, wrap in plastic wrap, and refrigerate up to 2 days. Frost the cake the day you plan to serve it for best texture.
How much strawberry purée do I need?
Purée 1 lb fresh strawberries until smooth, then measure out the amount your recipe specifies. Strain through a fine mesh if you prefer a seedless frosting.
Can I use frozen strawberries instead?
Yes, thaw and drain frozen strawberries thoroughly to remove excess moisture before puréeing, as excess liquid can affect cake texture.
Why use egg whites instead of whole eggs?
Egg whites create a lighter, more delicate crumb and allow the strawberry flavor to stand out without the richness of yolks.
How do I know when the cake is done baking?
Insert a toothpick into the center—it should come out with a few moist crumbs, not wet batter. The cake should also spring back when lightly touched.
