Preheat & Prep: Preheat your oven to 350°F (175°C). Butter your pie dish or spray with nonstick spray.
Make the Crust: Mix graham cracker crumbs, sugar, and melted butter in a bowl. Press firmly into the bottom of the pie dish. Bake for 8–10 minutes. Let it cool slightly while you prepare the filling.
Whisk the Filling: In a bowl, whisk together egg yolks, sweetened condensed milk, lime juice, and lime zest until smooth. Pour this creamy goodness over the warm crust.
Bake the Pie: Bake at 350°F (175°C) for 12–15 minutes, just until the filling is set but still slightly jiggly in the center. Pro tip: Overbaking = sad, rubbery pie.
Chill Out: Let the pie cool to room temperature, then refrigerate for at least 2 hours. The longer it chills, the more it sets—so patience is a virtue.
Top It Off: Whip the cream with powdered sugar until stiff peaks form. Spread over chilled pie and sprinkle with extra lime zest or decorate with lime slices.
Serve & Smile: Slice, serve, and watch everyone’s faces light up.
