In a small microwave-safe bowl or saucepan, gently melt the unsalted butter until just liquid. Be careful not to brown it.

Add the granulated sugar and ground cinnamon to the melted butter.

Mix the ingredients thoroughly with a spoon or whisk until well combined and smooth. This method ensures a more even filling with the same amount of sugar and cinnamon on each roll, preventing any dry spots or lumps.

Place the mixed filling in the refrigerator for 30 minutes. This chilling step is crucial for achieving the desired consistency, allowing the butter to firm up slightly and bind with the sugar and cinnamon.

After chilling, the filling will be perfectly mixed, with no sugar lumps or butter lumps. It will have a spreadable, paste-like consistency, making it easy to apply to your cinnamon bun dough without being hard, messy, or runny.

Spread the prepared filling evenly onto your rolled-out cinnamon bun dough.
