Ingredients

Scale

Cake Base:

  • 3 cups all-purpose flour
  • 1 1/2 teaspoons baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup unsalted butter (softened)
  • 1 3/4 cups granulated sugar
  • 4 large eggs (room temperature)
  • 1 cup buttermilk
  • 1/4 cup key lime juice
  • 1 teaspoon vanilla extract
  • Zest of 3 limes
  • Green food coloring (optional)

Crust:

  • 1 1/2 cups graham cracker crumbs
  • 1/4 cup granulated sugar
  • 1/2 cup unsalted butter (melted)

Frosting and Garnish:

  • 1 cup unsalted butter (softened)
  • 8 ounces (226 grams) cream cheese (softened)
  • 4 cups powdered sugar (sifted)
  • 2 tablespoons key lime juice
  • 1 tablespoon lime zest
  • 1 teaspoon vanilla extract
  • Additional lime zest
  • Thinly sliced lime rounds
  • Crushed graham cracker crumbs

Instructions

  1. Preheat oven to 350°F and prepare three 8-inch round cake pans by greasing and flouring the surfaces.
  2. Create a crisp graham cracker foundation by mixing crumbs, sugar, and melted butter, then firmly pressing the mixture into the bottom of each pan.
  3. Whisk together dry ingredients including flour, baking powder, baking soda, salt, and vibrant lime zest in a medium bowl.
  4. Using an electric mixer, cream butter and sugar until the mixture becomes light and airy, then incorporate eggs one at a time, ensuring thorough blending after each addition.
  5. Infuse the batter with tangy key lime juice and aromatic vanilla extract, mixing until well combined.
  6. Alternate adding flour mixture and buttermilk to the wet ingredients, starting and ending with flour. Mix gently until just incorporated. Optional: Introduce a subtle green hue with food coloring.
  7. Distribute the batter evenly across the prepared cake pans, ensuring uniform thickness.
  8. Bake for 25-30 minutes until a toothpick inserted comes out clean. Allow cakes to rest in pans for 10 minutes, then transfer to wire racks for complete cooling.
  9. Craft a velvety frosting by whipping softened butter and cream cheese until smooth. Gradually fold in powdered sugar, key lime juice, zesty lime zest, and vanilla extract until creamy.
  10. Assemble the cake by layering each cake round, spreading frosting between each layer and covering the entire exterior with the remaining frosting.
  11. Elevate the presentation by piping decorative swirls, garnishing with fresh lime slices, additional lime zest, and sprinkled graham cracker crumbs.

Notes

  • Swap graham cracker crust with gluten-free cookies for a celiac-friendly version that maintains the classic crumbly texture.
  • Use natural food coloring like matcha or spirulina powder instead of artificial green food coloring for a healthier cake appearance.
  • Reduce sugar content by replacing half the granulated sugar with monk fruit sweetener or stevia for a lower-calorie dessert option.
  • Enhance moisture by adding a tablespoon of sour cream or Greek yogurt to the batter, preventing the cake from becoming dry during baking.
