Ingredients
  

For the Crust:

  • 1 package 8.8 oz. or 250g Biscoff cookies
  • 5 Tbsp. unsalted butter melted

For the Filling:

  • 3 large egg yolks at room temperature
  • 2 tsp. key lime zest
  • 1 can 14 oz. sweetened condensed milk
  • 2/3 cup key lime juice
  • Pinch of salt

For the Whipped Cream:

  • 1 1/2 cups cold heavy cream
  • 1/4 cup powdered sugar plus more to taste
  • 1 tsp. vanilla extract
  • 1 Tbsp. sour cream

Instructions
 

  • Preheat the oven to 350°F (175°C) and line an 8x8-inch pan with parchment paper.
  • Make the crust: In a food processor, pulse the Biscoff cookies until finely crushed. Add melted butter and pulse until combined. Press the mixture evenly into the prepared pan.
  • Bake the crust for 10 minutes, then set it aside.
  • In a mixing bowl, beat egg yolks and lime zest on high speed for 2-3 minutes until slightly thickened.
  • Add sweetened condensed milk, beat for 1-2 minutes until thicker.
  • Turn off the mixer, add lime juice and salt, stir until combined. Pour the filling over the crust.
  • Bake for 10-15 minutes until mostly set with a slight jiggle in the center.
  • Cool to room temperature, then refrigerate for at least 3 hours or overnight.
  • For the Whipped Cream:
  • In a bowl, beat heavy cream on medium-high speed until soft peaks form (1-2 minutes).
  • Add powdered sugar, vanilla, and sour cream. Beat until medium peaks form.
  • Spread whipped cream over the chilled pie bars, refrigerate for 30 minutes.
  • Garnish with lime zest before slicing and serving.

Notes

Notes:
For a lighter whipped cream layer, use 1 cup of whipped cream and adjust powdered sugar to taste.
