Spray muffin pan with cooking spray. Unroll Crescent rolls and cut them into squares (keep two triangles together and cut them in half to make a square), which will give you 8 squares. If using a standard size muffin tin, use one square per muffin pan hole. Push square of Crescent rolls into the muffin pan hole, leaving some hanging over the muffin pan hole edge.

Place a slice of brie, some cranberries, and some crumbled bacon into each muffin pan hole, on top of the Crescent roll dough.

Fold Crescent roll overfilling leaving a little bit exposed.
