How Many Calories in a Cookout Milkshake
How Many Calories in a Cookout Milkshake? Full Breakdown (2025 Updated)
If you’ve ever pulled up to a Cookout drive-thru late at night, you already know the struggle: the entire menu looks amazing, but those legendary milkshakes are calling your name. The only problem? You’re trying to keep track of calories — and Cookout isn’t exactly famous for putting nutrition info on the menu board.
So, exactly how many calories are in a Cookout milkshake?
Short answer: 510–1,050 calories per shake, with the average falling around 680–780 calories.
But there’s a lot more to it than that. Flavors, size, add-ins, and even which Cookout location you visit can change the numbers. Below is the most accurate and up-to-date calorie breakdown (2025) based on official Cookout nutrition data, customer testing, and recent lab analysis shared across Reddit, TikTok, and nutrition forums.
Cookout Milkshake Sizes — Yes, There’s Only One Size (Sort Of)
Cookout serves only one official milkshake size — a 20–22 oz cup (depending on how much whip and cherry they pile on top). They don’t offer “small” or “large” like most chains. What they do offer is over 40 flavors plus unlimited mix-ins, which is why the calorie range is so huge.
Calories by Popular Cookout Milkshake Flavors (Regular Size)
Here are the most accurate calorie counts for 2025:
| Rank | Flavor | Calories | Fat (g) | Carbs (g) | Sugar (g) | Protein (g) |
|---|---|---|---|---|---|---|
| 1 | Oreo Mint | 1,050 | 52 | 128 | 110 | 18 |
| 2 | Peanut Butter Fudge | 980 | 54 | 102 | 92 | 24 |
| 3 | Reese’s Cup | 950 | 50 | 108 | 98 | 22 |
| 4 | Chocolate Chip Cheesecake | 920 | 48 | 110 | 95 | 16 |
| 5 | Oreo | 898 | 44 | 112 | 96 | 16 |
| 6 | Peanut Butter Banana | 880 | 46 | 98 | 88 | 22 |
| 7 | Strawberry Cheesecake | 840 | 42 | 104 | 92 | 15 |
| 8 | Fresh Banana | 780 | 34 | 106 | 92 | 15 |
| 9 | Cappuccino | 750 | 36 | 94 | 84 | 14 |
| 10 | Vanilla | 680 | 34 | 82 | 74 | 14 |
| 11 | Chocolate | 680 | 34 | 84 | 76 | 15 |
| 12 | Strawberry | 610 | 30 | 78 | 72 | 13 |
| 13 | Fresh Peach (seasonal) | 540 | 28 | 72 | 68 | 12 |
| 14 | Hi-C Punch (lightest option) | 510 | 28 | 68 | 62 | 11 |
Real-world note: Many customers report that “double” flavors (e.g., Double Chocolate, Double Oreo) add roughly 100–180 extra calories.
Why Cookout Milkshakes Are So High in Calories
- Real Ice Cream Base
Cookout uses premium full-fat ice cream (not soft-serve or “frozen dairy dessert”). A single shake starts with ~16–18 oz of ice cream before milk and mix-ins. - Whole Milk
They blend with whole milk, not skim or 2%. This adds about 150–180 calories by itself. - Generous Mix-Ins
Oreo shake = 4–5 full Oreo cookies crumbled in.
Reese’s = 2 full-size cups chopped up.
Cheesecake flavors often include real cheesecake bites. - Whipped Cream + Cherry on Top
Adds another 50–80 calories most people forget to count.
Lowest-Calorie Cookout Milkshake Options (Under 600 Cal)
Trying to stay under 600 calories? Order one of these:
- Hi-C Punch (510 cal)
- Cherry Cobbler (seasonal, ~530 cal)
- Fresh Peach (seasonal, 540 cal)
- Strawberry (610 cal — close enough)
- Ask for “light ice cream” (some locations will do half the normal scoop — drops ~150–200 cal)
Pro tip: Ask them to make it with skim milk instead of whole — saves ~100 calories (not all locations will do this, but many will).
Highest-Calorie Cookout Milkshakes (Over 900 Cal)
Avoid these if you’re watching calories:
- Oreo Mint (1,050 cal)
- Peanut Butter Fudge (980 cal)
- Reese’s Cup (950 cal)
- Any “Cheesecake” flavor with extra Oreos or brownies mixed in (easily 1,000+)
How Cookout Milkshake Calories Compare to Other Chains
| Chain | Regular Shake Size | Average Calories | Highest Flavor |
|---|---|---|---|
| Cookout | ~21 oz | 780 | 1,050 (Oreo Mint) |
| Chick-fil-A | 20 oz | 590–720 | 720 (Cookies & Cream) |
| Shake Shack | 16 oz | 680–850 | 850 (Frozen Custard) |
| Sonic | 14 oz (mini-large) | 450–1,100 | 1,100 (Large) |
| Steak ‘n Shake | 12–20 oz | 600–950 | 950 (Large) |
| Dairy Queen | 21 oz | 520–1,040 | 1,040 (Royal) |
Cookout shakes are bigger and denser than most competitors, which explains why they often beat Chick-fil-A and Shake Shack in calorie count despite tasting “thicker.”
Can You Make a Lower-Calorie Cookout Shake at Home?
Yes — here’s a popular dupe that’s ~350 calories:
- 1.5 cups Halo Top Vanilla (210 cal)
- ½ cup fairlife 2% milk (65 cal)
- 1 tbsp peanut butter (90 cal)
- Ice + xanthan gum for thickness
Blend and you’ll get close to Cookout texture for less than half the calories.
Final Verdict — Are Cookout Milkshakes Worth the Calories?
If you’re having one once a month as a treat — absolutely yes. A 700–800 calorie shake is basically a full meal, so just treat it like one. Skip the fries or tray and you’re fine.
If you’re hitting Cookout 3–4 times a week… you might want to stick to the Hi-C Punch or Fresh Peach when it’s in season.
Bottom line: Cookout milkshakes range from 510 to 1,050 calories, with most popular flavors landing 680–900 calories. Now you know exactly what you’re sipping.
