# Instructions:

01 - Chill pie dough in the fridge for at least 2 hours. Roll it out into a 12-inch circle and place in a 9-inch pie pan. Crimp the edges and put it back in the fridge for 30 minutes.
02 - Cover the crust with parchment and pie weights, bake at 375°F for 15-16 minutes. Take weights out and poke holes in the bottom with a fork. Bake another 14-15 minutes until golden brown.
03 - Stir together brown sugar, egg yolks, milk, and cornstarch in a bowl till smooth.
04 - Heat granulated sugar and water in a pan until the mixture turns amber. Slowly add in the heavy cream while stirring.
05 - Pour the brown sugar mixture into the caramel, whisking continuously. Keep cooking until the mixture gets thick and registers 195-200°F.
06 - Take it off the heat and mix in butter, bourbon, vanilla, and salt. Let it cool for 5 minutes, then spread into the prepped crust.
07 - Refrigerate uncovered for at least 6 hours or overnight. After that, cover with plastic wrap.
08 - Whisk chilled cream, vanilla, and brown sugar till you get medium peaks. Spread it across the pie right before serving.
