1-First Step: Gather all ingredients including 1 ½ cups milk, 1 ½ cups vanilla bean ice cream, 1/8 teaspoon pure vanilla extract, 3 chocolate sandwich cookies, and 1 cup ice. Prepare by crushing the cookies into small pieces for even blending.

2-Second Step: Add the 1 ½ cups milk to the blender first, as this helps everything mix smoothly.

3-Third Step: Follow with 1 ½ cups vanilla bean ice cream and 1/8 teaspoon pure vanilla extract to build the creamy base.

4-Fourth Step: Add the 3 chocolate sandwich cookies next, then top with 1 cup ice to keep things chilled and frosty.

5-Fifth Step: Blend on high speed for 30 seconds to 1 minute until the mixture is smooth and creamy. If needed, pause to scrape down the sides for an even texture.

6-Sixth Step: Taste and adjust as desired, perhaps adding more milk for a thinner consistency or extra cookies for more crunch.

7-Final Step: Pour into chilled glasses and serve immediately. Top with whipped cream, crushed cookies, or chocolate syrup for extra flair. For adaptations, use plant-based milk for vegan options or gluten-free cookies as needed.
