1. Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper. This step always reminds me of my grandmother’s meticulous prep—it’s the little details that make a difference.
2. In a small skillet, melt the butter over medium heat. Add the diced apples, brown sugar, cinnamon, and lemon juice. Cook, stirring occasionally, for about 5 minutes until the apples are just tender but not mushy. Remove from heat and let cool slightly.
3. Carefully unroll the croissant dough and separate into triangles on a clean surface.
4. Place a small spoonful of the apple mixture near the wide end of each triangle, followed by a cube of brie. If you’re using nuts, sprinkle a few on top for extra texture.
5. Starting at the wide end, roll each triangle tightly toward the point, sealing the edges gently with your fingers. Don’t worry if they’re not perfect—homemade charm counts!
6. Brush each croissant bite with the beaten egg to help them achieve that golden, glossy finish we all love.
7. Arrange the bites on your prepared baking sheet, spacing them about an inch apart.
8. Bake for 12-15 minutes until the croissants are puffed and golden brown, and the cheese inside is melting deliciously.
9. Once out of the oven, drizzle with caramel sauce while still warm. This step makes all the difference—it’s like adding a little extra love right before serving.

From personal experience, I’ve found that letting the apple mixture cool a bit before assembling prevents soggy dough. Also, don’t skimp on the egg wash—it really amps up the croissant’s beautiful color and shine.
