If you’re serving a two-layer cake with filling, like many store-bought sheet cakes, you can generally cut smaller slices. Also, consider who you're feeding.

This single-bowl, fluffy white cake bakes in less than 20 minutes and is topped, while still warm, with a simple glaze.

Make sure every guest gets plenty of cake with our handy guide to sheet cake sizes and how many servings you can get out of each.
