Preheat Oven: Set to 350°F (175°C).
Make the Crust: In a food processor, pulse flour, sugar, vegan butter, dairy-free milk, and sea salt until a dough forms.
Bake the Crust: Press dough evenly into a 10-inch pie pan and bake for 18 minutes.
Prepare the Brownie Batter: Keep the oven at 350°F. In the food processor, blend flour, sugar, cocoa powder, baking powder, salt, melted vegan butter, applesauce, and vanilla until smooth. Fold in chocolate chips.
Bake the Brownie Pie: Pour the brownie batter onto the pre-baked crust, spread evenly, and bake for 25 minutes.
Cool & Chill: Let the pie cool completely—chill in the fridge for 2 hours for best texture.
Serve & Enjoy: Slice and top with your favorite toppings like vegan whipped cream or chocolate drizzle!
