Preheat the oven to 400F.
Line a baking sheet with parchment paper. Set aside.
Place 1 sheet of thawed puff pastry dough on the cutting board.
Cut down the middle, and then cut each piece in half. You should have 4 rectangles.
Place 6 Snickers minis per piece on one half of each rectangle - leaving 1/2 inch border for folding it over the candy.
Fill a small container with water, wet your finger and trace it around the border inside the rectangle.
Fold the second part of the dough over and press tightly to seal.
Brush with egg & water mixture.
Bake at 400 F for 20 minutes until golden brown.
Let cool for a few minutes. Serve right away and enjoy!
