The Cookout Peanut Butter Banana milkshake has the most fiber on the Cook Out menu: 5 grams, in a shake category where most flavors have none. It also ties for the most protein at 27 grams. The 32.8 oz cup holds 864 calories and typically costs $3.99. The argument around it is whether the banana shows up.
Does the banana show up in Peanut Butter Banana?
Reviewers disagree, and the disagreement is the review. Mashed ranked it 35th and called it a peanut butter shake with only the slightest hint of banana, saying the peanut butter completely overwhelms the banana's sweetness. A TikTok clip described rich peanut butter with limited banana chunks. The Daily Meal ranked it 12th and found the opposite, a balance of saturated, salty peanut butter and fresh, sweet banana. The fan scorer gave it 15.5 of 17 and said neither flavor dominates.
