Step 1: Preheat your oven to 375°F (190°C). Line a large baking sheet with parchment paper or a silicone baking mat.
Step 2: In a small bowl, combine the granulated sugar, ground cinnamon, and a tiny pinch of salt. Stir well to ensure the spices are evenly distributed.
Step 3: Unroll the crescent roll dough on a clean, lightly floured surface or directly onto your prepared baking sheet. Press the perforations together gently to form a solid rectangle of dough.
Step 4: Brush the entire surface of the dough generously with melted butter, ensuring every inch is covered.
Step 5: Evenly sprinkle the cinnamon sugar mixture over the buttered dough. Use your fingers to gently press the mixture into the dough so it adheres well.
Step 6: Starting from one of the longer sides, carefully roll the dough tightly into a log, aiming for a snug roll to prevent gaps.
Step 7: Using a sharp knife or unflavored dental floss, slice the log into 12 equal pieces, each about 1 to 1.5 inches thick. Place these slices, cut-side up, onto your prepared baking sheet, leaving a little space between them.
Step 8: Bake for 12-15 minutes, or until the twists are golden brown and puffed up.
Step 9: While the twists are baking, prepare the simple glaze. In a small bowl, whisk together the powdered sugar, milk (or water), and vanilla extract until smooth. Adjust consistency as needed.
Step 10: Once the twists are out of the oven, let them cool on the baking sheet for a few minutes before transferring them to a wire rack. Drizzle generously with the prepared glaze while they are still warm. Serve and enjoy!
