Essential Ingredient Guide

Key Lime Zest & Juice: Provides the signature citrus aroma; zest the limes before juicing for maximum flavor.
Unsalted Butter: Softened butter creates a tender crumb; avoid melted butter to keep structure.
Granulated Sugar: Adds sweetness and helps with browning; you can cup a bit of superfine sugar for a finer texture.
All‑Purpose Flour: Gives the cake its classic density; sift with baking powder for even rise.
Buttermilk: Adds moisture and a subtle tang that complements the lime.
Cream Cheese Frosting (optional): A light tangy frosting balances the lime; use a small amount to keep the cake the star.
