Preheat the oven to 350 degrees. Grease a 9″ pie plate generously with cooking spray and set aside.

Melt the butter in a medium bowl in the microwave. Add the graham crumbs, sugar, and pinch of salt and stir until the crumbs are coated with the butter.

6 tablespoons unsalted butter,2 tablespoons granulated sugar,pinch of salt,1 1/2 cups graham cracker crumbs

Pour the crumbs into the prepared pie plate and distribute evenly over the bottom. Press the crumbs evenly over the bottom working from the center toward the edges and up the sides. Bake for 10 minutes or until golden brown. Remove from heat and cool on a wire rack.

Lower the oven temperature to 325 degrees.

Place the egg yolks in a medium bowl and beat until combined. Add the key lime juice, zest, and condensed milk, and whisk until incorporated.

Pour the mixture over the crust and bake for 13-15 minutes or until the filling is set. Remove from heat and cool completely on a wire rack. Once the pie has cooled, chill in the refrigerator.

Dollop or pipe the cream around the edges and in the center before serving, and garnish with key lime slices and zest if desired. Serve and enjoy!
