The Cookout Hershey's Chocolate milkshake is the baseline every other chocolate shake gets measured against: 620 calories in a 32.9 oz cup, typically $3.99. Critics cannot agree on it. Mashed ranked it sixth and said it tastes like biting into a Hershey's bar. A fan scorer gave it 9.5 of 17 and called it run-of-the-mill. The Daily Meal put the plain chocolate shake 40th of 41.

Why do reviewers disagree on plain chocolate?
| Source | Verdict |
|---|---|
| Mashed | 6th; surprisingly rich, like a Hershey's bar; for people who live for chocolate |
| cookoutmilkshakereviews.com | 9.5 of 17; expected a fancy shake, found it run-of-the-mill |
| The Daily Meal | 40th of 41; smooth and sweet but plain, needs more chocolate |
It comes down to expectation. The fan scorer wanted an upgraded shake and compared it to a Frosty that is clumpier, more viscous and less gritty, calling it by no means terrible but short of a great chocolate shake. Mashed took it for what it is: chocolate and nothing else.
How does Hershey's Chocolate compare with Vanilla?
Chocolate adds 65 calories to the plain Vanilla shake and nothing else of note. Fat, saturated fat and protein barely move, and sodium rises by 15 milligrams.
| Measure | Vanilla | Hershey's Chocolate | Difference |
|---|---|---|---|
| Calories | 555 | 620 | +65 |
| Total fat | 18 g | 18 g | 0 |
| Sodium | 469 mg | 484 mg | +15 mg |
| Carbs | 86 g | 110 g | +24 g |
| Sugar | 83 g | 103 g | +20 g |
| Protein | 16 g | 16 g | 0 |
The chocolate contributes 20 more grams of sugar and no extra fat.
Where does the plain chocolate shake rank on the menu?
30th of 44 for calories, so it sits among the lighter half. The Daily Meal found it tasting plain because the chocolate comes from fudge sauce stirred into ice cream, with no pieces to add contrast. That is the opening other shakes fill: Double Chocolate has the same sauce plus flakes, and Fudge pushes the sauce further.
What allergens does it contain?
Our allergen chart lists milk as its only allergen. Shared equipment still carries cross-contact risk with every flavor.
Is the Cookout Hershey's Chocolate milkshake too plain?
Only if you want contrast. Order it for a thick, simple dessert under 650 calories and the best mixing partner on the menu, since chocolate takes on a second flavor without fighting it. The Mocha shake carries the identical label numbers in a bigger cup.
