YIPPIE bar # coco-dark chocolate by Weider . The new Yippie! Bar is the first bar filled with six different layers: a crunchy protein layer, a creamy protein filling, a delicious caramel topping with puffed rice and peanuts, and a milk chocolate bath with extra chocolate garnish. It is characterized by its exceptional flavor and its 36% protein content. Its carbohydrate content is lower than that of other similar bars, but the most important thing is that it contains less than 2 grams of sugar per bar.
