Ingredients for Key Lime Pie Bars
Crust
- vanilla wafer cookies, finely ground
- unsalted butter, melted
- brown sugar
Filling
- cream cheese, softened
- sweetened condensed milk
- lime zest
- egg yolks
- lime juice
Topping
- heavy cream
- powdered sugar
- Extra lime zest, for garnish
👩🏼🍳 Instructions
- Preheat your oven to 325°F. Line an 8×8-inch baking dish with parchment paper, letting some hang over the edges to make lifting the bars out easier.
- Start by making the crust. In a medium bowl, mix together the finely ground cookies, melted butter, and brown sugar until it looks like wet sand.
- Press the mixture firmly into the bottom of your baking dish, making sure it’s even. Bake for 8–10 minutes until golden, then set aside to cool.
- While the crust is cooling, prepare the filling, in a large bowl, beat the cream cheese until smooth.
- Add in the sweetened condensed milk, lime zest, egg yolks, and lime juice. Mix until everything is fully combined and silky.
- Pour this mixture over the cooled crust and smooth the top with a spatula.
- Bake for 20–25 minutes, or until the edges look set and the center has a gentle jiggle.
- Let it cool to room temperature, then place it in the fridge for at least 2 hours to set completely.
- Once chilled, make the whipped topping. In a clean bowl, beat the heavy cream and powdered sugar until soft peaks form.
- Spread the whipped cream evenly over the bars.
- Finish with a sprinkle of fresh lime zest for a pretty pop of color.
- Cut into 16 bars and serve cold.
These creamy treats are bursting with citrusy goodness! Think Carlota de Limón but with cream cheese.
