Ingredients
Scale
Crust:
- 1 1/2 cups graham cracker crumbs
- 1/4 cup granulated sugar
- 1/2 cup unsalted butter, melted
Lime Mousse:
- 1 cup lime juice (about 4-5 limes)
- 1 tablespoon lime zest
- 1 cup granulated sugar
- 4 large egg yolks
- 1/4 cup cornstarch
- 1 1/2 cups heavy cream
- 1 teaspoon vanilla extract
Cheesecake Filling:
- 2 cups cream cheese, softened
- 1 cup granulated sugar
- 1 teaspoon vanilla extract
Toppings:
- Fresh blackberries
- Fresh mint leaves
- Additional lime zest for garnish
Instructions
- Prepare the Crust: Preheat the oven to 350°F (175°C). In a medium bowl, combine graham cracker crumbs, granulated sugar, and melted butter, mixing well until the mixture is evenly combined. Press the mixture firmly into the bottom of a 9-inch springform pan to form an even crust.
- Bake the Crust: Place the crust in the preheated oven and bake for 10 minutes. Once baked, remove from the oven and let it cool completely to allow it to set and solidify enough for the filling.
- Make the Lime Mousse Base: In a medium saucepan, whisk together lime juice, lime zest, granulated sugar, egg yolks, and cornstarch until smooth. Cook this mixture over medium heat, stirring constantly to prevent lumps, until it thickens and comes to a gentle boil. Remove from heat and let it cool completely to room temperature.
- Whip the Cream: In a large bowl, whip the heavy cream and vanilla extract together using an electric mixer until stiff peaks form, ensuring a light and airy mousse texture.
- Combine Lime Mixture with Whipped Cream: Gently fold the cooled lime mixture into the whipped cream, mixing carefully until fully combined to maintain the mousse’s lightness.
- Prepare the Cheesecake Filling: In a separate large bowl, beat the softened cream cheese with granulated sugar until smooth and creamy using an electric mixer. Add vanilla extract and mix thoroughly until fully incorporated and silky.
- Assemble the Cheesecake Bars: Evenly spread the cheesecake filling over the completely cooled crust, smoothing the surface. Then pour the lime mousse evenly over the cheesecake layer, spreading gently to cover the entire surface.
- Chill to Set: Refrigerate the assembled cheesecake bars for at least 4 hours, or until the layers are fully set and firm to the touch.
- Garnish and Serve: Before serving, top the cheesecake bars with fresh blackberries and fresh mint leaves. Sprinkle additional lime zest over the top for a bright, decorative finish.
Notes
- Ensure the crust is cooled completely before adding the filling to prevent melting or mixing.
- Whip the heavy cream to stiff peaks carefully to create the perfect mousse texture.
- Use fresh lime juice and zest for the best flavor in the mousse.
- Refrigeration time is crucial to allow the cheesecake bars to set properly; do not rush this step.
- For easier slicing, chill the bars overnight and use a warm knife to cut clean pieces.
- Blackberries can be substituted with blueberries or raspberries if preferred.
