This green cookies and cream milkshake is a fun and festive treat perfect for seasonal celebrations or any time you want a splash of color in your dessert routine. With rich vanilla ice cream and crunchy chocolate sandwich cookies blended together, it’s a creamy delight that brings both sweetness and a little minty freshness when the extract is included.
I first made this with my daughter on St. Patrick’s Day and loved how it brightened up a gloomy afternoon and gave us a fun cooking project to enjoy together.
Ingredients
- Vanilla ice cream: Two cups for a rich and creamy base choose a highquality brand for the best texture
- Whole milk: Half a cup to smooth out the shake feel free to adjust for thickness or thinness
- Chocolate sandwich cookies: Six cookies such as Oreos add chocolatey crunch and flavor pick ones with classic filling for the best cookies and cream effect
- Mint extract: Quarter teaspoon adds a refreshing note but can be skipped or substituted for peppermint extract for a stronger flavor
- Green food coloring: Makes the shake vibrant and festive you can use natural options like spinach or matcha powder if you prefer
- Whipped cream: For topping to make it extra indulgent and visually appealing

Instructions
- Prepare Your Glasses:
- Drizzle chocolate syrup inside chilled serving glasses by slowly squeezing the syrup along the sides to create streaks that will set. Put the glasses in the freezer to set while you blend the shake so they stay frosty and cool.
- Blend the Shake:
- Add vanilla ice cream, whole milk, chocolate sandwich cookies, mint extract if using, and a few drops of green food coloring to your blender. Blend on high speed until the mixture is smooth and the color is even. Stop occasionally to scrape down the sides ensuring everything blends well. Adjust the thickness by adding milk one tablespoon at a time if needed for your preferred consistency.
- Pour and Decorate:
- Pour the milkshake carefully into the prepared glasses. Top each generously with whipped cream. Sprinkle crushed chocolate cookies on top and finish with another drizzle of chocolate syrup to make it look bakeryquality and irresistible.

My favorite ingredient is definitely the chocolate sandwich cookies because they add both texture and a rich flavor that really defines this shake. One of my favorite memories with this drink was making the milkshake on Halloween while we were all dressed up, turning an ordinary night into a playful family moment fueled by sweet treats.
Storage Tips
Keep leftovers in an airtight container in the freezer and allow the shake to thaw slightly before drinking to regain smoothness. Because of the cookies, it’s best enjoyed fresh but frozen portions can be a great way to prep ahead for a party.
Ingredient Substitutions
Use coconut or almond milk ice cream and matching plantbased milk for a dairyfree version that remains creamy and rich. Swap mint extract with peppermint extract for a stronger mint flavor or skip entirely if preferred. Replace artificial green food coloring with pureed spinach or matcha powder for natural color and additional flavor notes.
Serving Suggestions
This milkshake pairs wonderfully with salty snacks like popcorn or potato chips for a fun contrast. For kidfriendly parties, add gummy worms or edible candy eyes on top for a spooky Halloween vibe. It also works well with cookies and other crunchy treats on the side.

Serve chilled with extra crushed cookies on top for crunch. It makes a cheerful treat for parties or a quick family dessert.
