The Ingredients: What You’ll Need

Cookie Crust

• 2 cups vanilla wafer cookies, finely ground (250 g): Provides the sweet, buttery base for the bars.
• 5 tablespoons unsalted butter, melted: Helps bind the crust together while adding richness.
• 2 tablespoons light brown sugar: Adds a hint of caramel-like sweetness and depth.

Key Lime Pie Filling

• 1 tablespoon lime zest (packed, from 6–7 key limes): Infuses the filling with fragrant citrus oils.
• 5 large egg yolks: Adds richness and helps thicken the custard.
• 22 ounces sweetened condensed milk (1 14-ounce can and ¾ cup from a second can): Sweetens and creates the signature creamy texture.
• 1 cup freshly squeezed lime juice: The star of the show, providing that iconic tangy flavor.

Whipped Cream Topping

• 1 cup heavy whipping cream: Whips up into a light, airy topping.
• 2 tablespoons powdered sugar: Adds sweetness and stabilizes the whipped cream.

Step-by-Step Instructions

1. Preparing the Cookie Crust

1. Preheat the Oven: Adjust the oven rack to the middle position and preheat to 350°F. Line an 8×8-inch baking pan with parchment paper, allowing the sides to overhang for easy removal later.
2. Crush the Cookies: Grind vanilla wafer cookies in a food processor until they resemble fine crumbs.
3. Combine Ingredients: In a medium bowl, mix the cookie crumbs with melted butter and light brown sugar. The mixture should feel like damp sand.
4. Press Into Pan: Transfer the crumb mixture to the prepared pan and press it firmly and evenly across the bottom using a spatula or the back of a spoon.
5. Bake: Bake the crust for 13–15 minutes, then set aside to cool for about 30 minutes.

2. Making the Key Lime Pie Filling

1. Mix the Zest and Yolks: In a large bowl, combine the egg yolks and lime zest. Using a hand mixer, beat on medium speed for 4–5 minutes until the mixture thickens and lightens in color.
2. Incorporate Sweetened Condensed Milk: Add the sweetened condensed milk and beat for another 3 minutes to ensure a smooth, rich consistency.
3. Add Lime Juice: Whisk in the freshly squeezed lime juice until fully incorporated.
4. Assemble and Bake: Pour the filling over the cooled crust and bake for 15–17 minutes. The filling should be set but still slightly jiggle as a whole when gently shaken. Cool on the counter for 30 minutes before refrigerating for at least 3 hours or overnight.

3. Creating the Whipped Cream Topping

1. Whip the Cream: In a large bowl, beat the heavy whipping cream and powdered sugar using a hand mixer. Stop when stiff peaks form.
2. Spread Over Bars: Evenly spread the whipped cream over the chilled key lime filling using an offset spatula. Chill for at least 30 minutes before slicing.
3. Slice and Serve: Use the parchment overhang to lift the bars out of the pan. Slice into squares with a sharp knife, cleaning the blade between cuts for neat edges.

Flavors, Textures, and Aromas

Imagine biting into a square of these bars. First, you’ll experience the gentle crunch of the buttery cookie crust, followed by the creamy and tangy burst of the lime custard. The whipped cream topping adds a delicate fluffiness that balances the tartness of the filling. As you savor each bite, the citrusy aroma of lime zest mingles with the sweet scent of vanilla wafers, creating a sensory symphony that’s impossible to resist.

Tips and Variations

1. Ingredient Substitutions:
   • Vanilla Wafers: Swap with graham crackers or digestive biscuits for a different crust flavor.
   • Key Lime Juice: If key limes are unavailable, use regular lime juice, though the flavor will be slightly less floral.
2. Add a Twist:
   • Coconut Crust: Mix shredded coconut into the crust for a tropical vibe.
   • Chocolate Drizzle: Add a drizzle of dark chocolate over the whipped cream for a decadent touch.
3. Serving Suggestions:
   • Garnish: Top with lime slices, zest, or a sprinkle of crushed cookies.
   • Pairing: Serve with iced tea or a refreshing citrus cocktail for the ultimate summer treat.
4. Storage:
   • Store the bars tightly covered in the fridge for up to 4 days. For longer storage, freeze and defrost in the refrigerator before serving.
