However, when it comes to the best white chocolate on grocery shelves, these iconic brands aren't it. After tasting several contenders, it was Tony Chocolonely's white chocolate bar that surprisingly took the top spot in our ranking of six grocery store white chocolate bars. Secondly, the full-bodied flavor of the white chocolate was buttery, milky, and sweet. A 6.35-ounce bar of Tony's Chocolonely white chocolate costs just over $6 at Target, and one of the five-star reviews encapsulated our thoughts completely: "what more can you ask from a chocolate bar? Great taste made with great ingredients from great sources from a company that stands for a great cause."
