Prepare the pastry

• Line a baking sheet with some parchment paper or a silicone mat.
• Turn the oven on to 350F
• Take the package of puff pastry out of the refrigerator. Open the box and the paper slip that holds the sheets.
• Carefully open the folded sheets, one at a time, removing the strips of parchment paper.
• Using a rolling pin, gently roll the sheet to the edges keeping the rectangular shape.
• Cut vertically 3 strips per sheet (follow the fold) and horizontally in half with a pizza wheel or a sharp knife.
  
• Place a line of chocolate at the bottom and roll over it until it is covered.
  
• Add another line of chocolate and roll the rest of the strip. Pinch the end to keep the chocolate inside and place it on a lined baking sheet.
• Repeat with the rest of the pastry.
• Brush a little almond milk on top and sprinkle a little sugar. You can also add some slivered almonds on top.
  
• Bake for 20-25 minutes at 350F. Watch the last 5 minutes to make sure that the top doesn't burn.
• Set aside and let them cool down for 5-10 minutes before serving.
• Sprinkle some powdered sugar.
