Step 1- Preheat the Oven
Preheat your oven to 375°F.
Step 2- Roll Out the Pastry
Roll the two sheets of thawed puff pastry over a floured, flat surface into a 10 x 14-inch rectangle. Cut the pastry evenly into 24 equal squares.
Step 3- Shape the Pastry Cups
Spray a 24-cup mini muffin pan with nonstick cooking spray, then place a pastry square into each cup. Push the pastry down with your fingers to create little cups.
Step 4- Cut the Brie
Cut the plant-based brie into 24 small pieces. Keep the brie cold while you work so it doesn't turn into a sticky mess.
Step 5- Fill the Cups
Place a piece of brie into each pastry cup. Top with equal amounts of cranberry sauce spooned over each one.
Step 6- Add the Walnuts
Sprinkle a bit of the chopped walnuts onto each bite.
Step 7- Bake
Bake for 18 to 20 minutes, or until the pastry turns golden brown and the brie has melted.
Step 8- Cool and Drizzle
Let the bites cool for 5 minutes, then drizzle with maple syrup before serving.
