Ingredients
To create these delicious key lime pie bars, you’ll need the following ingredients:
- 12 full-sheet graham crackers (to yield 1 and 1/2 cups or 180g of graham cracker crumbs)
- 6 tablespoons (85g) unsalted butter, melted
- 1/4 cup (50g) granulated sugar
- 4 ounces (113g) full-fat brick cream cheese, softened to room temperature
- 4 large egg yolks
- 14-ounce (397g) can of sweetened condensed milk
- 1/2 cup (120ml) key lime juice
- 2 teaspoons lime zest (about 1 lime or 2 key limes)
- Optional for garnish: whipped cream and lime slices
Notes and substitutions:
- Graham cracker crumbs: You can use store-bought crumbs to save time, or make your own from whole graham crackers by crushing them.
- Cream cheese: Full-fat cream cheese gives the best texture but can be replaced with light cream cheese for a lower calorie option.
- Key lime juice: Freshly squeezed key lime juice offers the best flavor, but bottled juice is a simple alternative.
How to Make This Recipe Step by Step
-
Preheat your oven to 350°F (177°C). Line a 9-inch square baking pan with parchment paper, leaving some overhang on the sides. This will make it easier for you to lift the bars out later.
- Pro Tip: Use high-quality parchment paper for easy removal and to prevent sticking!
-
If you’re starting with full graham crackers, place them in a food processor to create fine crumbs, or put them in a zip-top bag and crush them with a rolling pin. In a medium bowl, mix graham cracker crumbs with granulated sugar and then stir in the melted butter. The mixture should feel sandy and thick.
- Pro Tip: Make sure there are no large chunks of crumbs for a smooth crust.
-
Press the crumb mixture evenly into the bottom of the lined baking pan.
- Pro Tip: Use the bottom of a measuring cup to really compact the crumb base for a sturdy crust.
-
Bake the crust for 10 minutes to help it set and develop flavor. Allow it to cool for a few minutes.
- Pro Tip: Keep an eye on it to ensure it doesn’t get too dark.
-
In a mixing bowl, use a hand mixer or stand mixer with a paddle attachment to beat the cream cheese on medium-high speed until smooth. This process should take about a minute.
- Pro Tip: Soften the cream cheese to room temperature for an easier blending process.
-
Add in the egg yolks and continue mixing until incorporated. Scrape down the sides of the bowl as needed.
- Pro Tip: Be sure to beat well to avoid any lumps in your filling.
-
Gradually mix in the sweetened condensed milk, key lime juice, and lime zest until well combined. After mixing, give it a final whisk by hand to eliminate any potential cream cheese lumps.
- Pro Tip: This extra step ensures a smooth texture in your final product.
-
Pour or spoon the filling evenly over the warm crust. Bake for about 18-20 minutes, until the edges are set, and the center remains slightly jiggly.
- Pro Tip: A little jiggle in the center is a good sign that you’ve got a creamy texture!
-
Once baked, allow the bars to cool at room temperature for about 30 minutes. Then, chill them in the refrigerator for at least 2-3 hours for the best texture and flavor.
- Pro Tip: Chilling helps the flavors meld beautifully!
-
Lift the bars out of the pan using the overhanging parchment paper and cut them into squares. Add toppings like whipped cream, lime slices, or extra lime zest to present beautifully.
- Pro Tip: For clean cuts, use a sharp knife and wipe it between cuts.
Serving Suggestions
These delightful bars can be served in various ways to enhance the overall experience:
- Pairings: Enjoy them with a refreshing glass of iced tea, lemonade, or even a fruity cocktail for a warm-weather treat.
- Occasions: Perfect for summer barbecues, picnics, birthday parties, or as a surefire crowd-pleaser at potlucks.
- Serving tips: Chill them in the fridge until serving, and consider garnishing each square with a dollop of whipped cream and a slice of lime for that extra touch.
Storage and Reheating Tips
To keep your leftovers fresh and delicious:
- Refrigeration: Store uneaten bars in an airtight container in the refrigerator for up to 5 days.
- Freezing: If you’d like to freeze them, wrap individual bars tightly with plastic wrap and place them in a freezer-safe container. They can last up to three months in the freezer.
- Reheating methods: While these bars are best served chilled, if you prefer a warm treat, you can briefly microwave a square for about 10-15 seconds.
Guaranteed Success Tips
To ensure that your dessert turns out perfectly every time, keep these tips in mind:
- Always use room temperature cream cheese for easier mixing and a smoother filling.
- Don’t overbake the filling; it should have a slight jiggle in the center when done.
- Make sure to cool the bars completely before chilling them to get the right texture.
- Use real key lime juice for the best results, especially if you’re aiming for authenticity in flavor.
- If substituting ingredients, be aware that the texture and taste may change slightly.
Recipe Variations
Shake things up with these fun variations:
-
Coconut Lime Bars: Add 1/2 cup of shredded coconut to the filling for a tropical twist that pairs beautifully with the key lime flavor.
-
Chocolate Drizzle: Once cooled, drizzle melted chocolate over the bars for a decadent touch that adds a rich contrast to the tangy lime.
-
Berry Topper: Top the bars with a mix of sliced berries (like strawberries and blueberries) before serving for an added pop of color and flavor.
