Ingredients

2 cups ice cream (any flavor) 1 cup milk 4 to 8 cookies (depends on type chosen)

Steps to Make It Blend ice cream and milk in a blender.  

Blend until smooth and serve. Throw a Cookie Milkshake Party Customized cookie milkshakes are a great idea for a children's party. Put out several toppings and let the children choose their favorite cookie and ice cream flavor combos. Use small cups so the kids can taste different options, as they like to mix up traditional combinations and they probably want to play around with different ingredients. Line up a few different blenders to make these concoctions, then start blending and serve a few different types of milkshakes. If you want to put a fancy spin on things, you can probably find cute plastic cups to jazz up the milkshakes. Here a few cookie milkshake options for a great party:

• The Cookie Monster: Combine Oreos and vanilla or chocolate ice cream into a smooth milkshake with a fun name.
• Peanut Butter Surprise: Peanut butter ice cream and Nutter Butters or peanut butter cookies, a cookie milkshake combo that you will not soon forget. (Beware of peanut allergies.) You could add a surprise by tossing in a peanut butter cup or chocolate chips.
• Caramel Frap: Similar to a caramel frappuccino, this cookie milkshake blends snickerdoodles and salted caramel ice cream into a Starbucks-like creation.
• The Animal: Animal crackers and vanilla ice cream incorporate simple flavors into a delicious treat. Make it a birthday party hit with sprinkles (actually, add sprinkles to every cookie milkshake).
• Cookie Dough Milkshake: Traditional chocolate chip cookies and vanilla ice cream or chocolate chip cookie dough ice cream...when blended, it's bliss.
• Gumby Shake: Blend up Thin Mints into chocolate or chocolate chip mint ice cream and you've got your own version of a Shamrock shake.Another way to create a cute presentation with your cookie milkshakes is to place a cookie on top of the milkshake. Poke a hole through it before you put the cookie on top and then stick a straw through the cookie. Or crumble cookie bits on top of the milkshake so kids can see the kinds of cookies involved. You can always pre-make the cookie milkshakes and then freeze them prior to serving.    https://www.thespruceeats.com/cookie-milkshake-recipe-305397
