Creating the perfect Cookies and Cream Cake is easy when you follow these steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and grease two 9-inch round cake pans.
2. Mix Dry Ingredients: In a large bowl, combine flour, sugar, cocoa powder, baking powder, baking soda, and salt.
3. Combine Wet Ingredients: In another bowl, whisk together milk, vegetable oil, eggs, and vanilla extract until well combined.
4. Combine Mixtures: Gradually add the wet ingredients to the dry ingredients, mixing until smooth.
5. Add Boiling Water: Carefully stir in the boiling water. The batter will be thin, but this is normal.
6. Fold in Cookies: Gently fold in the crushed Oreo cookies until evenly distributed.
7. Divide Batter: Pour the batter evenly into the prepared cake pans.
8. Bake: Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
9. Cool: Remove from the oven and let the cakes cool in their pans for 20-30 minutes. Then transfer them to wire racks to cool completely.
10. Make Frosting: In a large bowl, beat heavy whipping cream, powdered sugar, and vanilla extract until stiff peaks form.
11. Assemble the Cake: Place one cake layer on a serving platter. Spread a layer of frosting on top and sprinkle with crushed Oreo cookies. Add the second cake layer on top.
12. Frost the Cake: Use the remaining frosting to cover the top and sides of the cake.
13. Decorate: Top with additional Oreo cookies for a stunning finish.

These steps will guide you to create a delectable Cookies and Cream Cake that will be the centerpiece of any dessert table.
