Step 1: Preheat and Prepare Muffin Tin

Preheat the oven to 375°F (190°C). Grease a muffin tin or line each cup with paper liners.

Step 2: Roll Out the Puff Pastry

On a clean, flat surface, lightly flour the area. Unroll the puff pastry sheets and gently roll them out to ensure they are about 1/8-inch thick.

Step 3: Make the Cinnamon-Sugar Filling

In a small bowl, combine granulated sugar, brown sugar, cinnamon, and salt. Mix until well combined.

Step 4: Prepare the Pastry

Using a pastry brush, lightly brush a thin layer of melted butter over one side of the puff pastry.

Evenly sprinkle the cinnamon-sugar mixture over the buttered surface, covering the entire sheet.

Step 5: Shape the Cruffins

Cut the pastry into strips about 2-3 inches wide.

Take each strip and tightly roll it up, starting from one end, forming a spiral.

Place each rolled-up strip into the muffin tin, standing upright like a coil, so that they resemble a cruffin shape. Gently press the ends to secure the rolls in place.

Step 6: Bake the Cruffins

Brush the tops of each cruffin with the remaining melted butter and sprinkle any leftover cinnamon-sugar mixture over them.

Bake in the preheated oven for 20-25 minutes, or until golden brown and puffed up.

Step 7: Cool and Serve

Remove from the oven and let cool in the tin for 5 minutes before transferring to a wire rack to cool completely.
