Let’s Bake It Together: Step-by-Step

This is where it all comes together. Get ready to bake your new favorite dessert.

1. Preheat Your Equipment:
Preheat your oven to 350°F (175°C). Set out your pie dish.

2. Combine Ingredients:
In a mixing bowl, combine graham cracker crumbs, sugar, and melted butter. Stir until it resembles wet sand.

3. Prepare Your Cooking Vessel:
Press the mixture into the bottom and sides of your pie dish. Bake the crust for 10 minutes. Let it cool slightly.

4. Assemble the Dish:
In another bowl, whisk together sweetened condensed milk, egg yolks, lime juice, and zest until smooth and creamy.

5. Cook to Perfection:
Pour the filling into the pre-baked crust. Bake for 15 minutes, until the center is just set and jiggles slightly.

6. Finishing Touches:
Cool to room temperature, then chill in the refrigerator for at least 4 hours or overnight.

7. Serve and Enjoy:
Whip the cream with powdered sugar until stiff peaks form. Pipe or spread over the chilled pie. Garnish with lime zest or slices.

Creamy Meets Crisp in Every Bite

The contrast of that buttery, crunchy crust with the silky-smooth lime filling is everything. The whipped cream lightens the bite and rounds out the tartness, while the zest adds a burst of aroma just before each forkful. Every layer brings something unique to the table.

Quick Tips for Even Better Results

Let’s make sure your pie turns out stunning every time:

• Use room temperature eggs for a smoother filling.
• Don’t overbake—the center should jiggle just slightly.
• Chill the whipped cream bowl and beaters before whipping for better volume.
• Add extra zest on top for more lime flavor without extra tartness.

Avoid These Common Mistakes

Even a simple pie has its pitfalls. Here’s what to look out for:

• Undercooked crust: Bake the crust first so it doesn’t turn soggy.
• Runny filling: Bake until just set and chill thoroughly.
• Too tart or too sweet: Taste your filling before baking to adjust the balance.
• Over-whipped cream: Stop at soft or stiff peaks, not beyond.

Prep Ahead and Storage Tips

This pie is a make-ahead dream. Bake it a day in advance and chill overnight. Store leftovers covered in the fridge for up to 4 days. Avoid freezing once topped with whipped cream—freeze the base alone if needed.

How to Serve It Best

Serve chilled, with clean slices and a fresh zest sprinkle. A lime twist on the side adds visual pop. Pair it with iced tea or a citrusy mocktail for a refreshing combo.

What To Do With Leftovers

If you’re lucky enough to have a slice left, try these ideas:

• Crumble it into a parfait with yogurt or whipped cream.
• Freeze into mini pie pops.
• Use in a dessert trifle with berries and whipped cream.

More Little Tricks for Success

• Use parchment strips under the crust for easier slice removal.
• Zest your limes before juicing to save time.
• Add a pinch of sea salt to the crust for a deeper flavor.

Make It Picture-Perfect

Pipe whipped cream in decorative swirls or rosettes. Garnish with thin lime wheels or candied lime peel. Serve on a white plate to let that pale yellow filling pop.

Flavor Twists to Try
