How to Store Key Lime Cake
Leftover cake? Lucky you! Store your Key Lime Cake in an airtight container in the fridge, where it will stay fresh for about 4-5 days. Want to keep it for longer?

Tips to Make Key Lime Cake
- Room Temp Ingredients: For a fluffier cake, make sure your eggs and butter are at room temperature before mixing.
- Fresh Zest: Use fresh zest from key limes if you can — it adds a fabulous fragrance that dried zest just can’t compete with.
- Don’t Overmix: This keeps the cake tender. You want to mix until everything is just combined.
