Method
- Combine 1½ cups (135g) graham cracker crumbs, 3 tablespoons (38g) granulated sugar, and 3 tablespoons (45g) melted unsalted butter in a large bowl and stir with a silicone spatula until every crumb is evenly coated and the mixture clumps when pressed between your fingers.
- Divide the crumb mixture evenly among 6 glass jars — approximately 3 tablespoons (30g) per jar — and press firmly into the base using the flat bottom of a small measuring cup, working the crumbs slightly up the inner glass walls to form a defined crust edge.
- Place filled jars on a tray, cover loosely with plastic wrap, and refrigerate for a minimum of 15 minutes while you make the filling.
- In the bowl of a stand mixer fitted with the whisk attachment, or using a hand mixer, beat 12 oz (340g) full-fat block cream cheese on medium speed for 2 full minutes until completely smooth, pale, and lump-free — scrape the bowl sides and bottom before continuing.
- With the mixer on low, add ¾ cup (90g) sifted powdered sugar in two additions, then increase to medium and beat for 30 seconds until fully incorporated — scrape the bowl again.
- Add 3 tablespoons (45ml) fresh key lime juice, 1 teaspoon (5ml) pure vanilla extract, and the finely grated zest of 1 key lime and beat on medium speed for 45 seconds until smooth and uniform.
- In a separate cold bowl with clean beaters, whip ½ cup (120ml) cold heavy whipping cream on medium-high speed until it reaches stiff peaks — the cream should hold a firm point with no droop when the beater is lifted.
- Fold the whipped cream into the cream cheese mixture in two additions using a silicone spatula with slow strokes from the bottom of the bowl upward — do not stir in circles — until no white streaks remain.
- Remove the chilled jars from the refrigerator and divide the filling evenly among them — approximately 4 to 5 tablespoons (75–80g) per jar — smoothing the surface level with a small offset spatula, leaving ½ inch (1.2cm) of headspace below the rim.
- Cover loosely with plastic wrap and refrigerate for a minimum of 2 hours — 4 hours preferred, overnight best — until the filling is completely firm and springs back without leaving an indent when pressed lightly with a fingertip.
- Let store-bought lime curd sit at room temperature for 20 to 30 minutes to loosen slightly, then spoon approximately 1½ to 2 tablespoons (28–35g) of curd onto the surface of each fully set jar and tilt gently to self-level — do not spread aggressively.
- Cover and refrigerate for a minimum of 30 minutes to set the curd layer — jars can be held at this stage for up to 24 hours before finishing.
- Just before serving, whip ½ cup (120ml) cold heavy whipping cream with 2 tablespoons (15g) sifted powdered sugar and ½ teaspoon (2.5ml) pure vanilla extract on medium-high speed to stiff peaks.
- Fit a piping bag with a Wilton 1M or 2D star tip, fill the bag halfway, and pipe one rosette per jar by holding the bag perpendicular to the jar surface and piping in a slow circular motion from the outside edge inward with even pressure.
- Press one lime wedge into the side of each rosette at a slight angle, dust generously with finely grated lime zest, and serve immediately.
Notes
Cream cheese: Full-fat block cream cheese only — the kind sold in a foil-wrapped brick. Whipped, spreadable, and low-fat versions contain more water and will not set correctly.
Cream fat content: Heavy whipping cream must be 36% fat minimum. Cream labeled simply "whipping cream" at some brands contains only 30–35% fat and will not reach stiff peaks reliably.
Fresh lime juice: Do not substitute bottled lime juice — pasteurized bottled juice has a flatter flavor and weaker acidity, which affects both flavor and how firmly the filling sets.
Two-stage chill is structural: The filling must be fully firm before the curd layer goes on — a minimum of 2 hours, confirmed by the finger-press test. Adding curd to a soft filling causes the layers to bleed together and cannot be corrected.
Homemade lime curd: Whisk 3 large egg yolks, ½ cup (100g) granulated sugar, and ¼ cup (60ml) fresh key lime juice over a double boiler, stirring constantly until thick enough to coat the back of a spoon — approximately 8 to 10 minutes. Off heat, stir in 2 tablespoons (28g) cubed unsalted butter and 1 teaspoon lime zest. Strain through a fine mesh sieve, press plastic wrap on the surface, and refrigerate until fully chilled before using.
Piping tip: Wilton 1M or 2D star tip produces the defined ridged rosette shown in the photos. A zip-lock bag with the corner snipped works as a substitute but will not produce the same ridged finish.
Whipped cream topping: Pipe immediately before serving — do not pipe ahead. For a slightly more stable topping that holds 1 to 2 hours, add 1 teaspoon (3g) instant vanilla pudding powder to the topping cream before whipping.
Storage: Refrigerate untopped jars loosely covered for up to 3 days. Do not freeze assembled jars — the filling separates on thawing. Pipe the whipped cream topping fresh each time.
Make-ahead: Assemble through the curd layer up to 24 hours ahead. Pipe the cream and add garnish immediately before serving.
Scaling: All ingredients scale linearly. Chill time does not scale — individual jar set time is always a minimum of 2 hours regardless of batch size.
Allergens: Contains dairy, wheat (graham crackers), eggs (lime curd). Check store-bought curd label for additional allergens.
Altitude: Cream whips faster above 3,500 ft (1,065m) — begin checking for stiff peaks at the 1-minute mark to avoid overwhipping.
