Yes - there is about a third a bottle of Guinness Stout in the dough for these chocolate stout cinnamon rolls. This will essentially bake out in the process of this recipe, however, the Baileys in the frosting will stay boozy as this does not bake. If you want to make this recipe without the Baileys frosting to reduce the alcohol, you can easily substitute with a Cream Cheese frosting, like the one I use with my Blueberry Cinnamon Rolls or a vanilla glaze like the one I add to my Vanilla Bean Cinnamon Rolls. The recipe itself, however, is for Guinness Rolls, which means that the overall recipe does use alcohol. This has not been tested with reduced alcohol or alcohol free stouts.
