How to Make Green Cookies and Cream Milkshake

  1. Chill and prep

    Pop two glasses into the freezer for 10 minutes so your shake stays thick, and set out the ice cream to soften for 3 to 5 minutes for easier blending.

  2. Crush cookie garnish

    Smash 2 chocolate sandwich cookies in a bag with a rolling pin until you have a mix of crumbs and small bits for texture.

  3. Blend the base

    Add milk, vanilla ice cream, mint extract, a tiny pinch of salt, and 1 to 2 drops of green food coloring to the blender, then blend until silky and pale green.

  4. Pulse in the cookies

    Toss in 6 cookies and pulse 3 to 5 short times so you keep chunky cookie strata instead of turning it into mud.

  5. Dress the glass

    Drizzle chocolate syrup inside the chilled glasses while slowly rotating them to coat the walls in spooky streaks, then pour in the shake.

  6. Finish and serve

    Top with whipped cream, rain on the crushed cookies, and serve immediately while it is frosty and thick.

Substitutions

Green food coloring -> matcha or spinach
Use 1/2 to 1 teaspoon culinary matcha for an earthy, gently bitter green that plays well with chocolate, or blend in a small handful of baby spinach for a clean green color with virtually no flavor once sweetened.
Vanilla ice cream + mint extract -> mint chocolate chip ice cream
Swap both for the same volume of mint chip to bake in the minty vibe and add more chocolate crunch, giving you a naturally green base and a slightly bolder mint note.
Oreos -> gluten-free chocolate sandwich cookies
Use a good GF brand to keep the dark cookie color and crunch while making the shake friendly for gluten-free guests, with only a minor shift toward a slightly crisper crumble.

Tips

Blend smart, not long
Liquids go in first, then ice cream, then cookies last, and pulse to control texture so you get chunks instead of sludge.
Chill everything for body
Cold glasses, slightly softened ice cream, and cold milk deliver a thicker shake with less air and no sad melt.
Salt makes sweet pop
A tiny pinch of fine salt keeps the shake from tasting flat and heightens the chocolate and mint like magic.
Halloween glass trick
Drizzle chocolate syrup, then use a spoon back to drag it upward for creepy streaks that hold against the cold glass.
Color control
Add green dye one drop at a time and blend between additions so you hit Slimer-green without crossing into radioactive territory.
Texture insurance
If the blender stalls, stop, stir with a spoon to move heavy bits toward the blades, and add a tablespoon of milk at a time until it catches.

FAQ

My shake is too thick or too thin; how do I fix it fast?
If too thick, add milk 1 tablespoon at a time and pulse; if too thin, add 1 to 2 small scoops of ice cream and pulse, or park the glasses in the freezer for 3 minutes to tighten up.
The green is dull; how do I get brighter color without artificial dye?
Blend in 1/2 to 1 teaspoon matcha for vivid green and a subtle tea note, or a handful of baby spinach leaves for a clean emerald tone that disappears into the sweetness.
Can I make it ahead for a party?
Blend and pour into freezer-safe glasses, freeze up to 1 hour, then stir or pulse each glass for 10 seconds to re-smooth right before serving.
The mint tastes harsh; what did I do wrong?
Mint extract is potent, so use 1/8 to 1/4 teaspoon max, and balance with a pinch of salt; if it is already mixed, tame it by adding more vanilla ice cream and a splash of milk.
No blender available; any workaround?
Let the ice cream soften, whisk with milk in a large bowl until thick and smooth, then fold in crumbled cookies for texture.
How do I make it dairy-free without losing creaminess?
Use a rich oat or coconut ice cream with oat milk; both keep the body lush, and the chocolate-mint combo stands up to the subtle grain or coconut notes.

Serving Suggestions

For Halloween theatrics, rim the glass with crushed cookies and perch a candy eyeball on the whipped cream for instant campy drama.

If you want a grown-up version, splash in a little creme de menthe or vanilla vodka and thicken it back up with an extra scoop of ice cream, then serve with short straws and long spoons.
