Preheat your oven to 375°F (190°C).
If using store-bought puff pastry, simply thaw the dough as per the package instructions. Once thawed, lightly flour your work surface and roll the dough out to about 1/8-inch thick.
Cut the rolled-out dough into long strips, then divide each strip into triangle shapes. The wider base of the triangle will be the starting point for rolling.
Take each triangle and roll it up tightly, starting from the wide end and working your way to the tip.
Don’t roll it too tight—let the dough have some room to expand in the oven.
Place the croissants on a parchment-lined baking sheet, spacing them out evenly.
Brush the tops of each croissant with non-dairy milk for a golden, glossy finish. Optionally, you can lightly drizzle with maple syrup for a sweet touch.
Place the croissants in the oven and bake for 15-20 minutes, or until they are golden brown and puffed up. Keep an eye on them after 15 minutes to prevent burning.
After baking, let them cool for a few minutes before serving and enjoying. Enjoy the flaky, buttery goodness!
