1. 1. Prepare Your Work Surface and Oven: Preheat your oven to 375 F (190 C). Line a baking sheet with parchment paper or a silicone baking mat to prevent sticking and make cleanup easier. Lightly flour your clean kitchen counter or a large cutting board.

2. 2. Unroll the Dough: Carefully unroll the crescent roll dough onto your floured surface. You’ll see it’s typically pre-cut into triangles. Press the seams together gently to form a single, rectangular sheet of dough. You can use a rolling pin to lightly flatten it a bit more if needed, aiming for an even thickness.

3. 3. Create the Raspberry Filling: In a small bowl, gently combine the fresh raspberries, granulated sugar, all-purpose flour, active sourdough starter, melted butter, vanilla extract, and a pinch of salt. Mix just until the ingredients are combined, being careful not to crush the raspberries too much – you want some whole pieces for texture and bursts of flavor.

4. 4. Spread the Filling: Evenly spread the raspberry mixture over the entire surface of the crescent roll dough rectangle, leaving a small border (about half an inch) along one of the longer edges. This border will help seal the roll.

5. 5. Roll and Slice: Starting from the longer edge opposite the small border, carefully and tightly roll the dough into a log. Once rolled, use a sharp knife (a serrated knife works well) to slice the log into 8-10 equal-sized rolls, about 1 to 1.5 inches thick.

6. 6. Arrange and Bake: Place the sliced rolls cut-side up on your prepared baking sheet, leaving a little space between each one to allow for expansion. Bake for 12-15 minutes, or until the rolls are golden brown and the filling is bubbly. Keep an eye on them to prevent over-browning.

7. 7. Prepare the Glaze: While the rolls are baking, whisk together the powdered sugar and 1 tablespoon of milk or cream in a small bowl until smooth. If the glaze is too thick, add the remaining tablespoon of milk or cream a little at a time until you reach a pourable consistency.

8. 8. Glaze and Serve: Once the rolls are out of the oven, let them cool on the baking sheet for a few minutes. While still warm, drizzle the prepared glaze generously over the top of each roll. Serve immediately and enjoy!
