Cake
- 2 ⅔ cups all-purpose flour (333 g)
- 2 cups granulated sugar (400 g)
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- 1 teaspoon table salt
- ½ cup unsalted butter (113 g), cut into 8 pieces
- ¼ cup avocado, vegetable, or canola oil (60 ml)
- 1 Tablespoon lime or key lime zest (from about 2 limes)
- 1 ½ Tablespoons key lime juice
- 1 ½ scant cups whole milk (333 ml)
- 3 large eggs
- 1 teaspoon vanilla extract
Key Lime Curd
- ⅓ cup key lime juice (80 ml)
- 2 Tablespoons granulated sugar
- ¼ teaspoon table salt
- 2 Tablespoons unsalted butter (28 g), cut into pieces
- 2 large egg yolks
Frosting
- ¾ cup unsalted butter (170 g), softened
- 6 oz cream cheese (170 g), softened
- 4–5 cups powdered sugar (500–625 g)
- ¼ cup graham cracker crumbs (28 g), for decorating
- ½ batch stabilized whipped cream frosting (optional but recommended)
- Prepare pans and preheat oven: Preheat oven to 350°F (175°C). Thoroughly grease and flour the sides of three 8-inch cake pans, tap out excess flour, and line the bottoms with parchment paper to ensure easy release.
- Mix dry ingredients: In a large bowl or stand mixer fitted with paddle attachment, combine flour, sugar, baking powder, baking soda, and salt, ensuring even distribution.
- Add butter: With mixer on low speed, add softened unsalted butter one tablespoon at a time, mixing thoroughly until the mixture resembles sandy crumbs with a crumbly texture.
- Incorporate oil and zest: Stir in oil and lime zest until well combined, then set the mixture aside.
- Prepare wet ingredients: In a large measuring cup, combine key lime juice and whole milk up to the 1 ½ cup line. Whisk in eggs and vanilla extract until smooth.
- Combine wet and dry: Slowly add the milk mixture to the dry ingredients with the mixer on low speed, pausing to scrape bowl sides and bottom. Batter should be silky, smooth, and uniform.
- Divide and bake: Evenly pour batter into prepared pans (about 460 grams per pan by weight). Bake on the center rack for 26-28 minutes or until a toothpick inserted comes out clean or with a few moist crumbs.
- Cool cakes: Let cakes cool in pans for 10-15 minutes, then loosen edges with a knife and invert onto cooling racks to cool completely while preparing frosting.
- Make key lime curd: In a small non-reactive saucepan, whisk together egg yolks, key lime juice, sugar, and salt. Add butter pieces and cook over medium-low heat, whisking constantly until thickened and coats the back of a spoon. Strain through a fine mesh sieve into a heatproof bowl and cool completely, refrigerating if desired.
- Prepare frosting: Beat softened butter and cream cheese in a large bowl with an electric mixer until smooth and creamy. Gradually add 4 cups (500g) powdered sugar, blending completely. Add cooled curd one tablespoon at a time (5-6 tablespoons total), mixing thoroughly. Adjust sweetness and thickness with remaining powdered sugar as needed.
- Level and frost cake: Once cooled, level cake tops if needed. Spread frosting evenly between layers and cover the outside of the cake smoothly with the remaining frosting.
- Decorate: Gently press graham cracker crumbs around the cake base about a quarter of the way up. Optionally, pipe, swirl, or dollop stabilized whipped cream frosting on top and garnish with extra graham crackers or lime zest.
- Chill and serve: Refrigerate the frosted cake for at least 30 minutes before slicing to allow flavors to meld and frosting to set. Serve and enjoy your vibrant key lime cake!
Notes
- Use a non-reactive pan (stainless steel or ceramic) when making the curd to avoid discoloration or metallic taste.
- Stabilized whipped cream frosting adds decorative flair and creaminess but is optional.
- Ensure all butter and cream cheese are softened to room temperature for smooth frosting.
- Key lime juice can be substituted with regular lime juice if key limes are unavailable but expect slight flavor variation.
- Adjust powdered sugar in frosting for desired sweetness and consistency.
- Use parchment paper liners for easy cake removal and to prevent sticking.
- Chilling the cake before cutting produces cleaner slices.
