Method
 

Preparation
  1. Preheat your oven to 350 degrees F. Line an 8x8 square baking pan with parchment paper.
  2. In a food processor, pulse Biscoff cookies into fine crumbs. Add melted butter and pulse until mixture resembles wet sand.
  3. Firmly press the crumbs into the bottom of the prepared pan into an even layer. Bake for 12 minutes, then allow to cool for 10 minutes.
Making the Filling
  1. Reduce the oven temperature to 325 degrees F. In a large bowl, beat egg yolks with an electric hand mixer for about 3 minutes, until frothy and light in color.
  2. Add sweetened condensed milk and blend until incorporated.
  3. Mix in key lime juice, heavy cream, vanilla extract, and zest until fully combined.
  4. Pour the filling over the baked crust. Bake for 20-30 minutes until edges are set and the center is slightly jiggly.
  5. Allow to cool to room temperature, then refrigerate for at least 4 hours, ideally overnight.
Whipped Topping
  1. In a large mixing bowl, combine cold heavy cream, sour cream, vanilla extract, and powdered sugar.
  2. Whip on medium speed for 1 minute, then increase to high and whip until stiff peaks form, about 3-5 minutes.
Serving
  1. Spread the whipped cream evenly over the chilled bars. Serve immediately or refrigerate until ready to serve.

Notes

For best texture, do not skip letting the bars cool before refrigerating. Using fresh key limes enhances the flavor.
