Cookout Double Chocolate Milkshake: Taste, Price, Calories & Honest Review

Cook Out’s menu board has more than 40 milkshake flavors on it, and honestly, the first time you see that list you might just freeze up at the drive-thru window. But if you’re someone who thinks regular chocolate shakes are too weak, there’s one flavor that solves that problem completely: the Double Chocolate Milkshake.

I’ve tested this flavor in multiple drive-thrus across different states to see if it’s actually worth the hype. Here is my honest breakdown of the price, actual calorie count, and whether it’s worth skipping the classic vanilla for.

The Cookout Double Chocolate Milkshake is a rich chocolate dessert made with vanilla soft serve and extra chocolate syrup. It typically costs around $3.99 and contains approximately 650 calories. It’s one of the chain’s most popular milkshakes for chocolate lovers seeking a thicker and more intense flavor.

What is the Double Chocolate Milkshake?

Think of it this way: a regular chocolate shake at Cookout is already pretty rich. The double chocolate version takes that same base and pours in extra chocolate syrup — basically doubling down on the cocoa flavor instead of keeping it mild and balanced.

The difference shows up immediately. Where a standard chocolate shake tastes sweet with a hint of cocoa, this one tastes like actual melted chocolate got blended into ice cream. It’s darker, heavier, and noticeably more intense from the first sip.

If you’ve ever wished your chocolate shake tasted more like a chocolate bar than a chocolate-flavored syrup, this is that.

What’s Actually In It

Cook Out doesn’t publish a detailed ingredient breakdown for every shake flavor, but based on how the shake looks, tastes, and holds up, here’s what’s going on behind the counter:

The soft-serve base. Cook Out uses the same high-fat vanilla soft serve across all its shakes. This is part of why their shakes are famous for being thick — a thinner ice cream base would turn watery the second you add extra syrup.

Double the chocolate syrup. Instead of the single pump (or however they measure it) that goes into a regular chocolate shake, this one gets noticeably more. It’s mixed all the way through, so you’re not just getting a chocolate-flavored top layer with vanilla underneath — every spoonful tastes the same.

A finer ice texture. The consistency stays smooth instead of grainy, which matters a lot once you’ve left a milkshake sitting in your cup holder for ten minutes in summer.

Calories & Nutrition Facts

If you’re keeping an eye on what you eat, you’ll want to know this isn’t a light treat — and honestly, nobody ordering a “double” anything is expecting it to be. Here’s the general nutritional picture for a standard-size shake:

Note: Cook Out doesn’t list official nutrition info on receipts or in-store, so these numbers are commonly cited estimates based on similar fast-food milkshake formulations. If you have specific dietary needs, it’s worth calling your local Cook Out directly.

How Does It Compare to a Regular Chocolate Shake?

A standard chocolate shake from Cook Out typically lands somewhere in the 560–580 calorie range. Going “double” adds that extra syrup, which can push the total up by roughly 70–90 calories — and it bumps the sugar content up noticeably too.

So yes, you’re paying a calorie premium for the extra chocolate, but if you’re already at Cook Out ordering a shake, calories probably weren’t the main concern to begin with.

What It’s Actually Like to Drink

During my visits to Cook Out locations in, Apex Nc, Foley Al, North Carolina, Tennessee, and Virginia, I found the Double Chocolate Milkshake consistently thicker than the standard chocolate version.

Here’s the part most reviews skip over: this shake is genuinely too thick for a straw, at least at first. I’ve tried multiple times to power through with the straw they hand you, and every time I end up switching to a spoon within the first few minutes. That’s not a complaint — it’s basically the whole point.

The flavor itself doesn’t taste artificial or overly candy-like. It’s a deeper, more “adult” chocolate flavor — closer to dark chocolate than to chocolate milk. There’s no bitterness to it, but the richness builds as you go.

By the halfway mark, it starts to feel pretty heavy, especially if you’ve already eaten a full meal. For someone who just wants a light dessert, it might be more than enough on its own. But if you’re a real chocolate person, this is one of those shakes you’ll keep thinking about after you finish it.

How to Customize Your Order (Local Favorites)

One of the best things about Cook Out is that the menu is basically a starting point — you can ask them to blend almost anything into your shake. A few combinations that work especially well with the double chocolate base:

Peanut butter add-in: Ask for fresh peanut butter blended in. It turns the shake into something close to a frozen peanut butter cup, and the saltiness actually balances the sweetness nicely.

Chocolate mint: A small amount of mint flavoring cuts through the heavy cocoa and gives it a cleaner finish — good option if you find the regular version a bit too rich.

Cheesecake or Oreo mix-in: Blending in a piece of their chocolate fudge cheesecake or some Oreo pieces adds texture and an extra layer of flavor, though it does make an already-heavy shake even heavier.

What to Order With It (So You Don’t Get Overwhelmed)

This shake is sweet enough that pairing it with something salty or savory makes a real difference. A couple of combos that work well:

Cajun fries or onion rings — the seasoning and saltiness reset your palate between sips, so the chocolate doesn’t start to feel one-note.

A Cook Out burger or BBQ tray — the smoky, savory flavor of a charbroiled burger or pulled pork sandwich gives your taste buds somewhere to “land” between bites of the shake.

Allergens and Dietary Notes

Contains dairy. The soft-serve base means this isn’t an option for anyone who’s lactose intolerant or has a dairy allergy.

Possible soy and gluten cross-contact. Chocolate syrups often contain soy lecithin, and like most fast-food kitchens, there’s some risk of cross-contamination from shared equipment. If you have a severe allergy, it’s worth asking your local location about their specific syrup ingredients.

Vegetarian-friendly. There’s no meat, lard, or gelatin in the recipe, so it works fine for vegetarians.

Pros & Cons of the Cook Out Double Chocolate Milkshake

What People Are Saying About It

Search around food forums and social media, and the Double Chocolate Milkshake comes up again and again as one of Cook Out’s better-kept secrets. The most common praise points to the portion size and the price — it’s usually around $3.99, which feels like a steal for how much shake you actually get.

The complaints are pretty consistent too: it melts fast on hot days (which, given how thick it starts out, says something), and it’s genuinely hard to finish if you’ve also ordered a full tray.
