Bonefish Grill Key Lime Cake Recipe: Tangy Layers With Creamy Frosting

There’s something extraordinary about a perfectly balanced key lime cake—where tangy citrus meets velvety frosting in every bite. This Bonefish Grill-inspired version captures that signature contrast with a tender cake base, vibrant lime curd, and a creamy frosting that ties everything together. The secret lies in using fresh key lime juice for that authentic Florida flavor.

The magic happens in the layering: moist vanilla cake provides structure, while the zesty lime curd adds brightness, all enveloped in a rich cream cheese frosting. Unlike traditional versions that rely solely on graham cracker crusts, this recipe builds complexity through texture and flavor contrast. It’s the kind of dessert that impresses without requiring advanced baking skills.

Ingredients for Bonefish Grill Key Lime Cake

Optimal ingredient selection ensures the signature Bonefish Grill balance of tangy citrus and velvety cream cheese frosting.

The key lime juice is non-negotiable for authentic Florida flavor. Nellie & Joe’s Famous Key West Lime Juice (available at Publix or online) provides consistent quality when fresh limes aren’t accessible. For the cream cheese, Philadelphia brand yields the ideal texture—avoid tub varieties as they contain stabilizers that compromise frosting structure. Buttermilk should be full-fat; Kate’s Real Buttermilk is preferred for its rich, cultured profile.

Substitutions require careful balance. Bottled lime juice (like ReaLime) works in emergencies but lacks depth—supplement with additional zest. For the graham crust, Anna’s Swedish Thins provide superior texture to generic brands. The cake flour can be replicated by replacing 2 tbsp of all-purpose flour with cornstarch per cup. Vegan adaptation requires aquafaba for meringue layers and coconut oil for butter, though flavor profiles will diverge from the original.

Storage demands precision. The assembled cake maintains integrity for 3 days refrigerated—store under a cake dome to prevent frosting absorption. Unfrosted layers freeze for 2 months; thaw overnight before assembly. Key lime juice retains potency for 1 week refrigerated in airtight containers. Always bring refrigerated ingredients to room temperature before mixing to ensure proper emulsion in both cake batter and frosting.

Step-by-Step Instructions for Key Lime Cake

This methodical approach ensures perfectly balanced layers with the signature tangy-sweet profile.

Step 1: Prepare the Graham Cracker Crust

Combine the 1.5 cups Graham Cracker Crumbs with ¼ cup of the Granulated Sugar and 6 tablespoons of melted Unsalted Butter. The mixture should resemble wet sand when pressed between your fingers. This texture ensures the crust will hold together when sliced.

Press the crumb mixture evenly into the bottom of a 9-inch springform pan, using the bottom of a measuring cup to compact it firmly. Bake at 350°F for 8-10 minutes until the edges are light golden brown and the center is set. Let cool completely before adding the filling—this prevents the crust from becoming soggy.

Step 2: Create the Key Lime Custard Filling

In a medium saucepan, whisk together the remaining 1¼ cups Granulated Sugar, Key Lime Zest, Key Lime Juice, and Large Eggs (yolks only). Cook over medium-low heat for 8-10 minutes, stirring constantly with a silicone spatula, until the mixture thickens to a pudding-like consistency that coats the back of the spoon.

Immediately remove from heat and strain through a fine-mesh sieve to eliminate any cooked egg bits or zest fibers. Stir in 4 tablespoons of the Unsalted Butter until fully incorporated. Pour the custard over the cooled crust and refrigerate for 2 hours until completely set—the surface should be firm to the touch when gently pressed.

Step 3: Bake the Vanilla Cake Layers

Preheat oven to 350°F. In a stand mixer, cream the remaining Unsalted Butter with ¼ cup Granulated Sugar on medium-high speed for 3-4 minutes until light and fluffy. Add the Large Eggs (whites only) one at a time, mixing well after each addition, then incorporate the Vanilla Extract.

In a separate bowl, sift together the All-Purpose Flour, Baking Powder, Baking Soda, and Salt. Alternate adding the dry ingredients and Buttermilk to the butter mixture, beginning and ending with flour. Divide the batter evenly between two 8-inch cake pans lined with parchment. Bake for 25-30 minutes until a toothpick inserted in the center comes out clean and the tops spring back when lightly pressed.

Step 4: Assemble the Cream Cheese Frosting

Using the paddle attachment, beat the Cream Cheese on medium speed for 2 minutes until completely smooth with no lumps. Gradually add the Confectioners’ Sugar, mixing on low speed initially to prevent a sugar cloud, then increasing to medium once incorporated.

With the mixer running, slowly pour in the Heavy Cream and continue beating for 3-4 minutes until the frosting is light, fluffy, and holds stiff peaks. The ideal consistency should spread easily but maintain defined swirls when piped. Use immediately for best texture, as the frosting will firm up when refrigerated.

Step 5: Construct and Finish the Cake

Place one vanilla cake layer on a serving plate and spread with ½ cup of the cream cheese frosting. Top with the chilled key lime custard layer, then add the second cake layer. Apply a thin crumb coat of frosting and refrigerate for 30 minutes to set.

Frost the entire cake with the remaining cream cheese frosting, creating decorative swirls with an offset spatula. For clean slices, chill the assembled cake for 1 hour before serving. The layers should present distinct textures: crisp graham crust, creamy lime filling, moist vanilla cake, and velvety frosting in each bite.

Perfect Pairings for These Flavors

Tropical Cocktails

Nothing complements this cake better than a Key Lime Martini—mix 2 oz vanilla vodka, 1 oz key lime juice, and ½ oz simple syrup with ice, then strain into a chilled glass. The citrus-forward profile mirrors the cake’s filling while the vodka’s smoothness balances the sweetness. 🍸

For a non-alcoholic option, try a Sparkling Limeade with 1 part fresh lime juice, 2 parts sparkling water, and 1 tsp honey. The effervescence cleanses your palate between bites, making each forkful taste as vibrant as the first.

Coffee Pairings

A cold brew concentrate with 1 oz vanilla syrup creates a creamy contrast to the cake’s tang. I love Chameleon Cold-Brew for its smooth, low-acid profile that doesn’t compete with the lime flavors. Serve over ice with a splash of half-and-half.

For hot coffee lovers, a cinnamon-dusted cappuccino adds warming spice notes that complement the vanilla cake layers. The foam’s richness echoes the cream cheese frosting’s texture, creating a harmonious pairing experience.

Dessert Wines

A Moscato d’Asti from Piedmont offers the perfect balance—its peach and apricot notes enhance the lime’s brightness while the gentle sweetness matches the frosting. Chill to 45°F for optimal crispness. I recommend Saracco Moscato d’Asti for its consistent quality.

For something bolder, try a late-harvest Riesling with its honeyed stone fruit flavors. The wine’s acidity cuts through the cake’s richness, creating a sophisticated contrast that elevates both the dessert and the drink.
