Follow these simple steps to create these irresistible Cranberry Brie Bites. The process is straightforward, making it perfect for even novice bakers.

1. Preheat Your Oven & Prepare Baking Sheet: Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper. This prevents sticking and makes cleanup a breeze. Parchment paper is truly your best friend in baking!
2. Prepare the Puff Pastry: Gently unfold the thawed puff pastry sheet on a lightly floured surface. If your pastry is rectangular, you may want to lightly roll it out to even it out slightly and make it easier to cut into squares. Aim for a square or rectangle of about 12×12 inches.
3. Cut the Puff Pastry: Using a sharp knife or pizza cutter, cut the puff pastry into 2-inch squares. You should get around 36 squares from a standard sheet of puff pastry. Try to make the squares as even as possible for uniform baking.
4. Prepare the Brie: Cut the brie cheese into small cubes, roughly ½ inch in size. You want pieces that will fit comfortably within the puff pastry squares without being too bulky. If using a brie wedge, remove the rind if it’s thick or tough; otherwise, the rind is often edible and adds flavor.
5. Assemble the Brie Bites: Place a puff pastry square in each cup of a mini muffin tin (or you can arrange them directly on the prepared baking sheet if you prefer a flatter bite). Gently press the pastry into the cup or flatten slightly on the baking sheet to create a small well.
6. Add Brie and Cranberry Sauce: Place a cube of brie cheese into the center of each puff pastry square. Top with a small spoonful (about ½ teaspoon) of cranberry sauce. Be careful not to overfill, as this can cause the filling to spill out during baking.
7. Optional Toppings: If using, sprinkle chopped walnuts or pecans over the cranberry sauce. You can also add a few finely chopped fresh rosemary or thyme leaves at this stage for an herbaceous touch.
8. Egg Wash: In a small bowl, whisk together the egg with a tablespoon of water to create an egg wash. Brush the edges of each puff pastry square with the egg wash. This will give them a beautiful golden color and enhance browning.
9. Bake: Bake in the preheated oven for 15-20 minutes, or until the puff pastry is golden brown and puffed up, and the brie is melted and gooey. Keep an eye on them as baking times can vary slightly depending on your oven.
10. Cool Slightly & Serve: Once baked, remove the Cranberry Brie Bites from the oven and let them cool in the muffin tin or on the baking sheet for a few minutes before serving. This allows the brie to set slightly and makes them easier to handle.
11. Optional Drizzle: If desired, drizzle a touch of honey or maple syrup over the warm brie bites just before serving for an extra touch of sweetness and glaze.
12. Garnish & Serve Warm: Garnish with fresh rosemary or thyme sprigs, if desired, and serve warm. These are best enjoyed immediately while the pastry is flaky and the brie is melty.
