If you’re not a big beer drinker (or not a big Guinness Stout drinker), you might be wondering if an Irish Guinness Cake tastes like beer. The answer is...not really. In fact, the flavors in Guinness pair so well with chocolate that it really just enhances the chocolate flavor of the cake and gives it a slightly smoky, malty flavor. If you’re at all on the fence about using Guinness in the cake, just use water instead of Guinness (as with the One Bowl Chocolate Cake this recipe is adapted from).
