Kirkland Signature
Chocolate Peanut Butter Chunk

What's in the Chocolate Peanut Butter Chunk Kirkland Signature bar?
Kirkland Signature’s Chocolate Peanut Butter Chunk sticks to a classic dairy duo for protein—milk protein isolate plus whey isolate—then leans on real peanut butter, peanut flour, and Dutch‑processed cocoa to land the chocolate‑chunk flavor.
Carbs come mostly from soluble tapioca fiber, a refined fiber made from cassava, with erythritol and a touch of stevia providing sweetness instead of sugar. Fat stays modest and mostly peanut‑derived, with a little cocoa butter for richness.
The additive list is short and functional—sweeteners plus a pinch of sunflower lecithin to keep everything smooth—yielding 21g of protein, 23g of carbs, 6 grams of fat, and just 2g of sugar in 190 calories.
What are people saying?
Main praise: Fans love the efficiency: 21g of high‑quality protein for 190 calories, solid satiety, and value that makes it easy to keep on hand.
Main criticism: A firm, sometimes inconsistent chew and a stevia/erythritol finish divide tasters—and a subset report GI upset from the sugar alcohols.
