Ingredients You’ll Need

You only need a few basic ingredients to make these bars. Most of them you may already have at home:

For the crust:

• 1½ cups graham cracker crumbs
• ⅓ cup melted butter
• 2 tablespoons sugar (optional for added sweetness)
• For the filling:
• 1 can (14 oz) sweetened condensed milk
• 8 oz cream cheese, softened
• ½ cup key lime juice (or regular lime juice)
• 1 tablespoon lime zest (for extra flavor)
• 1 teaspoon vanilla extract
• 1 cup whipped topping (like Cool Whip) or homemade whipped cream

Toppings (optional):

• Extra whipped cream
• Lime slices or zest
• Crushed graham crackers

Step-by-Step Instructions

1. Make the Crust
   In a mixing bowl, combine the graham cracker crumbs, melted butter, and sugar (if using).
   Press the mixture firmly into the bottom of an 8×8-inch pan lined with parchment paper.
   Place in the fridge to chill while you make the filling.
2. Make the Filling
   In another bowl, beat the softened cream cheese until smooth.
   Add in the sweetened condensed milk, lime juice, lime zest, and vanilla. Mix until creamy and fully combined.
   Gently fold in the whipped topping until smooth and fluffy.
3. Assemble the Bars
   Pour the filling over the chilled crust and smooth out the top.
   Cover the dish and place in the fridge for at least 4 hours, or until firm. For quicker results, freeze for 1–2 hours.
4. Slice and Serve
   Once chilled and set, lift the bars out using the parchment paper.
   Slice into squares and top with whipped cream, lime zest, or graham cracker crumbs if you like. Enjoy cold!

Tips for the Best Key Lime Pie Bars

• Use fresh lime juice for the best flavor, but bottled key lime juice works too.
• Chill completely before slicing to get clean, firm bars.
• Line your pan with parchment paper to make lifting and slicing easier.
• Want a firmer bar? Freeze it slightly longer and serve partially frozen for a more ice cream-like texture.

Fun Variations to Try

• Tropical Twist: Add shredded coconut to the crust or sprinkle on top.
• Low-Sugar Option: Use low-fat cream cheese and light whipped topping.
• Mini Bars: Make in a muffin tin with liners for grab-and-go servings.
• Vegan Version: Use dairy-free cream cheese, coconut condensed milk, and a vegan whipped topping.

What to Serve With Key Lime Pie Bars

These creamy bars are great on their own, but you can pair them with:

• Iced tea or lemonade
• Fresh berries on the side
• A scoop of vanilla ice cream
• A sprinkle of toasted coconut

Make Ahead, Storage, and Freezing Tips

Make Ahead:
These bars are perfect to prepare the night before. Chill overnight for best texture.

Storage:
Store in an airtight container in the fridge for up to 4–5 days. Keep cold until ready to serve.

Freezing:
These bars freeze beautifully! Wrap tightly and freeze for up to 1 month. Thaw slightly before serving or enjoy frozen for a firmer treat.

Recipe FAQ’s

Can I use regular lime juice instead of key lime?
Yes! Key limes have a sweeter taste, but regular limes work just fine.

Do I need to bake the crust?
Nope! The butter helps it hold together once chilled.

Can I make these in a bigger pan?
Yes, just double the ingredients for a 9×13-inch pan. Chill time may be a bit longer.
