The Cinnabon Clusters had a very earthy cinnamon smell. It reminded me of semi-sweet chocolate chips with a pinch of cinnamon.
Top layer: Chocolate covered toffee and pecans = There was much more toffee than pecans. The cinnamon didn't mesh well with the toffee and chocolate. It was too many flavors competing.
Center layer: Cinnamon mousse = The mousse was grainy. I was expecting a gooey filling. The cinnamon mousse was instead thicker than nougat. The overall flavor was cinnamon flavored sand.
Bottom layer: Chocolate = Had a decent amount of chocolate. But it was bland and lacked bitterness.
Thumbs down for Cinnabon Cinnamon Mousse Pecan Cluster.
ETA: If you were thinking "what the heck is Makara Cinnamon ?", as I was, here's what Cinnabon says:
"In order to make the world’s greatest cinnamon rolls, Cinnabon buyers traveled the spice-growing regions of the globe to find the best, most flavorful cinnamon. They finally discovered cassia trees high in the mountains of Indonesia and used the bark to create the legendary Makara Cinnamon"
A long explanation begins further down the release starting at "The Legend of Makara Cinnamon."
