Key lime pie bars ingredient breakdown

Butter, flour, brown sugar and ginger snaps.

Gingersnap cookies – Provide a warm, spicy base that’s more interesting than a plain graham crust.

Melted butter – Binds the crumbs and creates a rich, golden crust.

Egg yolks, lime, cream cheese and condensed milk.

Egg yolks – Make the filling silky and smooth.
Sweetened condensed milk – Gives sweetness and the classic key lime custard texture.
Cream cheese – Adds a touch of tang and creaminess to balance the citrus.
Key lime juice – The bright, tart star of the filling.
Lime zest – Intensifies the lime aroma and flavor.

Faqs for this recipe

Can I use regular limes instead of key limes?

Yes. Key limes are traditional and slightly more aromatic, but regular limes work well if key limes aren’t available.

What if I can’t find gingersnap cookies?

Graham crackers can substitute in a pinch. To mimic the gingersnap spice, add a pinch of ground ginger and cinnamon to the crumbs.

Can I make key lime pie bars ahead of time?

Absolutely. These bars firm up and taste better after chilling for a few hours or overnight, making them ideal for make-ahead dessert planning.

Ingredients

Gingersnap crust:

▢ 2 cups gingersnap cookies, finely crushed
▢ ½ c butter , melted
▢ ¼ c brown sugar
▢ 6 tbsp flour

Filling:

▢ 4 egg yolks, large
▢ 14 oz sweetened condensed milk, can
▢ 4 oz cream cheese, softened to room temperature
▢ ½ c key lime juice, regular limes can substitute
▢ 2 tsp lime zest

Instructions

Preheat the oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving some overhang for easy removal.
Make the crust: crush gingersnaps finely using a food processor or place them in a sealed bag and crush with a rolling pin. In a bowl combine the crumbs, brown sugar and flour, then stir in the melted butter until the mixture holds together. Press the crumb mixture firmly and evenly into the bottom of the prepared pan using the back of a spatula.
Bake the crust for 10 minutes, then remove and let it cool slightly before adding the filling.
Prepare the filling: beat the cream cheese until smooth, then add the egg yolks and mix until combined. Stir in the sweetened condensed milk, key lime juice and lime zest, mixing until the filling is silky and homogeneous.
Pour the filling over the pre-baked crust and bake for about 15 minutes, until the filling is set but still slightly jiggly in the center. Let the pan cool on the counter for 30 minutes, then refrigerate for at least 2 hours to fully set.
To serve, lift the bars from the pan using the parchment overhang and slice into even squares. Serve plain or dusted with powdered sugar and garnish with lime slices if desired.
