Can I skip the egg yolks in this recipe?

You can replace the 2 egg yolks with 2 tbsp additional yogurt or sour cream. However, the filling may not feel quite as set.

Can I adjust the sweetness of this recipe?

Yes! You can taste the filling before the addition of the egg yolks. Start with 1.5 cans of sweetened condensed milk and then add more according to your taste. Just know the sweetened condensed milk is important for the texture too, not just flavor.

How to tell when Key Lime Pie Bars are done baking?

When you gently shake the pan, the edges should be slightly set but the center should still jiggle. Don't worry, the bars will set in the fridge. Avoid overbaking as the bars will become dry or eggy.

How to cut Key Lime Pie Bars into neat squares?

Firstly, trim off the edges from the pie using a large sharp knife. When cutting the bars, make sure your knife is sharp, and wipe it clean between every cut. When removing the knife after making a cut, swipe it horizontally instead of pulling it upwards, so the layers remain unmixed as much as possible.

How to store Key Lime Pie Bars?

Keep these bars in an airtight container in the fridge for 3-4 days.

Can I make these Key Lime Pie Bars in advance?

Yes! You can make the bars in advance and keep them covered in the fridge for up to 3 days. I recommend adding the whipped cream layer when you are ready to serve.

Cook Mode Prevent your screen from going dark

Instructions

Pre-heat oven to 350F (conventional) and prepare a 9x9" square baking pan by lining it with 2 perpendicular sheets of parchment paper. Make sure the parchment paper is rising to the top of the pan as that will allow you to remove the bars from the pan once they have set
Grind the graham crackers into a find crumb in your food processor. Mix with the melted butter
Transfer the crumbs to the prepared pan and press down tightly to form a crust on the bottom, using the back of a spoon and / or measuring cup
Bake the crust for ~8-10 minutes, then reduce the oven temperature to 325F
In the meanwhile, zest and juice the key limes
Mix the zest, key lime juice, sweetened condensed milk, vanilla and sour cream (or yogurt) with a hand whisk until combined. I recommend starting with 1/2 cup lime juice and 1 1/2 cans of sweetened condensed milk, tasting and adjusting from there
Add the egg yolks and whisk to combine
Transfer the filling to the pan on top of the baked crust. Shake and tap the pan on the counter to get rid of any air bubbles
Bake for ~17-18 minutes at 325F until the filling looks somewhat set around the edges but gently jiggles in the middle when the pan is shaken. It will not be fully set, as it will set further as it chills
Refrigerate overnight, or at least for 4 hours
When the bars are set, prepare the whipped cream topping by whisking the heavy cream with sugar until it reaches stiff peaks. Do not overmix
Slather the whipped cream on top of the filling inside the pan
Carefully remove the bars from the pan by lifting the parchment papers and transfer to your serving board
Cut into squares with a sharp knife, serve and enjoy!
