Start by making a homemade pie crust or using a pre-made one for convenience.
In a mixing bowl, combine pitted cherries and blueberries with sugar, cornstarch, vanilla extract, and a splash of bourbon for depth of flavor.
Roll out the pie crust and line a pie dish with it. Pour the fruit filling into the crust, spreading it out evenly.
Roll out another piece of pie dough and place it over the fruit filling. Crimp the edges to seal the pie.
Cut slits or create decorative vents in the top crust to allow steam to escape during baking.
Brush the top crust with beaten egg for a golden and glossy finish.
Bake the pie in a preheated oven until the crust is golden brown and the filling is bubbling.
Allow the pie to cool slightly before serving to let the filling set.
Slice and serve the vanilla bourbon cherry-blueberry pie with a scoop of vanilla ice cream or a dollop of whipped cream for a delicious treat!
