INGREDIENTS SECTION
- 1 1/2 cups graham cracker crumbs: Use fresh crumbs for the best flavor. You can substitute with digestive biscuits if preferred.
- 1/3 cup granulated sugar: White sugar works perfectly here; you can also use coconut sugar for a unique twist.
- 1/2 cup unsalted butter, melted: Always use unsalted to control the salt levels. Make sure the butter is room temperature for easy mixing.
- 1 cup sweetened condensed milk: This is your creamy base! Opt for a high-quality brand like Eagle Brand for the best results.
- 1/4 cup brown sugar: Packed brown sugar adds a rich flavor. You can use light or dark depending on your taste preference.
- 2 tablespoons butter: Use unsalted butter again here; this will help to create a glossy filling.
- 1 1/2 cups white chocolate chips: I love using Ghirardelli for their rich quality. You can also use white chocolate bars chopped into chunks.
- 1/2 cup heavy cream: For the best results, use heavy whipping cream; it will make the topping luxuriously creamy.
- 1/4 cup fresh key lime juice: Fresh is best! If you can’t find key limes, Persian limes will work (but might be a bit milder).
- 1 tablespoon key lime zest: The zest adds an aromatic kick; always zest before juicing the limes.
- 4 oz cream cheese, softened: It should be at room temperature for easy mixing.
- Extra lime zest (optional): For garnish, if you’re feeling fancy!
- Lime slices or twists (optional): Perfect for adding a touch of elegance on top.
STEP-BY-STEP INSTRUCTIONS
-
Preheat the Oven: Start by preheating your oven to 350°F (175°C).
-
Prepare the Crust: In a large bowl, combine 1 1/2 cups graham cracker crumbs, 1/3 cup granulated sugar, and 1/2 cup melted unsalted butter. Mix until the texture resembles wet sand. Firmly press the mixture into a lined 8×8-inch pan. Bake for 8 to 10 minutes, until golden brown. Let cool completely.
-
Make the Middle Layer: In a medium saucepan over medium heat, combine 1 cup sweetened condensed milk, 1/4 cup brown sugar, and 2 tablespoons unsalted butter. Stir continuously until thickened and smooth, about 5 to 7 minutes. Pour the mixture over the cooled crust and allow it to set while you prepare the next layer.
-
Create the White Chocolate Mousse: Heat 1/2 cup heavy cream in a small saucepan until warm but not boiling. Pour it over 1 1/2 cups white chocolate chips in a bowl and let it sit for about a minute. Stir until the mixture is smooth. Then, add in 4 oz softened cream cheese, 1/4 cup fresh key lime juice, and 1 tablespoon key lime zest, whisking until fully combined.
-
Layer It Up: Pour the white chocolate lime mixture over the middle layer, spreading it evenly.
-
Chill: Cover the bars with plastic wrap and refrigerate for at least 4 hours to set. For cleaner slices, I recommend chilling overnight.
-
Serve and Enjoy: Once set, lift the bars from the pan using parchment paper, cut into squares, and garnish with extra lime zest or lime slices if desired.
Chef’s Tips:
- If your filling is too thick, add a bit more heavy cream.
