Preheat the oven: Start by preheating your oven to 350°F (175°C). Spray a 12-cup muffin tin with non-stick spray to prevent any sticking.
Prepare the crescent roll dough: Take each tube of crescent roll dough and roll it into a rectangle. Be sure to seal any seams if necessary to maintain the filling.
Mix the filling: In a bowl, combine ½ cup unsalted butter, 1 tbsp chives, and 1 tbsp minced garlic. Mix well until fully combined, then spread this filling generously over the rolled-out dough.
Add cheese: Top the spread with 3 cups of shredded mild cheddar cheese, ensuring an even layer across the dough.
Roll and shape: Carefully roll the dough into a tight log, then cut it into pieces about 1-2 inches thick. Twist each piece into cinnamon roll shapes and place them cut-side up in the prepared muffin tin.
Bake: Place the muffin tin in the preheated oven and bake for 20-25 minutes, or until the tops are golden brown and the cheese is bubbling.
Prepare garlic butter: While the cruffins bake, mix the garlic butter ingredients: 3 tbsp melted butter, 1 tsp garlic, 1 tsp chives, and 1 tsp kosher salt in a small bowl.
Brush and serve: Once the cruffins are golden and baked through, remove them from the oven and brush generously with the garlic butter immediately. Serve warm and enjoy!
