Creating Cookie Ice Cream Sandwiches can be fun and straightforward if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper.

2. Cream the Butter and Sugars: In a large bowl, use a hand mixer or stand mixer to cream the softened butter, granulated sugar, and brown sugar until light and fluffy.

3. Add Eggs and Vanilla: Mix in the eggs, one at a time, and then stir in the vanilla extract until well combined.

4. Combine Dry Ingredients: In a separate bowl, whisk together flour, baking soda, and salt.

5. Mix Dry and Wet Ingredients: Gradually add the dry ingredients to the wet mixture, mixing until you have a dough. Be careful not to overmix.

6. Fold in Chocolate Chips: Gently fold in the chocolate chips or your chosen mix-ins for texture and flavor.

7. Scoop the Dough: Using a cookie scoop or spoon, drop rounded tablespoons of dough onto the prepared baking sheets, keeping them about 2 inches apart.

8. Bake the Cookies: Bake in the preheated oven for 10-12 minutes or until lightly golden brown around the edges. The centers should still look soft.

9. Cool the Cookies: Remove from the oven and let the cookies cool on the baking sheets for 5 minutes before transferring them to wire racks to cool completely.

10. Assemble Sandwiches: Once the cookies are cool, take one cookie, add a scoop of ice cream on top, and press another cookie on top to create a sandwich.

11. Freeze for Better Texture (Optional): If desired, place the assembled sandwiches in the freezer for about 30 minutes to help them hold their shape.
