These wafers have a nice flavor all around, even though( I think) some flavors are better tasting than others. The wafers are dense and crunchy and the filling in between the layers is barely perceptible on each bite as far as texture, but the flavor pops through. That is to say, you don't get the typical sandwich-effect where the outer layers are largely tasteless and function only to hold the center. With these wafers, the flavor is all around, and then there is the top chocolate layer (which gets gooey if you store them in a warm place).
At 13g of carbs per bar you can most certainly incorporate this into a keto diet as a snack, especially if you are working out and are trying to pack in the protein anyway you can. The only thing that had occasion to give me pause, is the fact that these are sweetened with sucralose, which is a shame, because I am trying to wean myself off these sucralose type sweetener things..
