This tastes exactly like the Cinnamon Crumble on top of the pastry dish for which it gets its name. It's more spicy cinnamon than sweet cinnamon but both come through on the exhale. The thing that disappointed me is that the flavor is advertised as partially a "fluffy cake that starts with a cake mix"but the cake flavor is only mildly present on the inhale. This is one that could double its rating with the stronger presence of that creamy cake mix flavor and if the cinnamon spice/sweetness was in better proportion.
I used the 50% off coupon to try a bunch of their flavors so I can't say I'm that disappointed, maybe with longer curing the cake flavor will come out!
