The Oreo milkshake is a popular beverage that combines the creamy goodness of milkshakes with the beloved Oreo cookie. While I don't have access to the most up-to-date information beyond my September 2021 knowledge cutoff, I can provide you with some details about the history of Oreo milkshakes up until that point.

The Oreo cookie itself was introduced by the National Biscuit Company (now known as Nabisco) in 1912. It quickly gained popularity and became one of the best-selling cookies in the United States.

The idea of blending cookies and milk together to create a milkshake is believed to have originated in the United States in the early 20th century. However, the specific origin of the Oreo milkshake is unclear, and it's difficult to pinpoint the exact moment it was first made.

Milkshakes in general gained popularity in the 1930s and 1940s, with the advent of electric blenders and the rise of soda fountain shops. These shops would often offer various flavors of milkshakes, and it's likely that the Oreo milkshake was eventually introduced as a creative variation.

Over time, the Oreo milkshake became a staple in many diners, ice cream parlors, and fast-food chains around the world. The combination of creamy vanilla ice cream, milk, and crushed Oreo Cookies created a delightful treat loved by many.

The popularity of Oreo milkshakes has continued to grow, and today you can find them in numerous establishments, ranging from small local ice cream shops to large fast-food chains. Additionally, people have developed their own recipes for making Oreo milkshakes at home, adding their own twists and variations to the classic recipe.

Please keep in mind that this information reflects the knowledge I have up until September 2021, and there may have been further developments or variations in the history of Oreo milkshakes since then.

Certainly! Here's a simple recipe for an Oreo milkshake:

Ingredients:

- 4-5 Oreo cookies

- 2 cups of vanilla ice cream

- 1 cup of milk

Instructions:

1. Start by separating the Oreo cookies. Scrape off the cream filling and set it aside. You'll use it later.

2. Place the Oreo cookies (without the cream filling) into a ziplock bag and crush them into small pieces using a rolling pin or your hands.

3. In a blender, combine the vanilla ice cream, milk, and the Oreo cream filling that you set aside. Blend until smooth and creamy.

4. Add about half of the Crushed Oreo Cookies into the blender and pulse a few times to incorporate them into the mixture. Save the remaining crushed Oreos for topping.

5. Pour the milkshake into glasses.

6. If desired, top the milkshake with whipped cream and drizzle chocolate sauce over it.

7. Sprinkle the remaining crushed Oreo cookies on top.

8. Serve immediately with a straw and enjoy your delicious Oreo milkshake!

Note: You can adjust the quantity of Oreo cookies based on your preference for a stronger or milder Oreo flavor.
