Why You’ll Love This Recipe

• Baking Mix Shortcut: Using a yellow or white cake mix base enhanced with lime gelatin gives the cake its signature light green tint and perfectly soft crumb without extra fuss.

• Double Citrus Punch: Freshly squeezed Key lime juice (or standard Persian lime juice) goes into both the cake batter and the sweet glaze.
