Creating these amazing Oreo Cupcakes is easy if you follow these steps:

1. Preheat the Oven: Set your oven to 350°F (175°C) and line a muffin tin with cupcake liners.
2. Mix Dry Ingredients: In a large bowl, sift together the flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt.
3. Cream Butter and Sugar: In another bowl, beat the softened butter until creamy. Gradually add the sugar and mix until light and fluffy.
4. Add Eggs and Vanilla: Incorporate the eggs, one at a time, mixing well after each addition. Add the vanilla extract and combine.
5. Combine Mixtures: Gradually alternate adding the dry ingredients and buttermilk to the butter mixture, starting and ending with dry ingredients. Mix until just combined.
6. Fold in Oreos: Gently fold in the crushed Oreo cookies into the batter.
7. Divide Batter: Fill each cupcake liner about 2/3 full with the batter.
8. Bake: Place the muffin tin in the preheated oven and bake for 20-25 minutes, or until a toothpick inserted in the center comes out clean.
9. Cool: Remove the cupcakes from the oven and let them cool in the tin for 10 minutes. Then, transfer them to a wire rack to cool completely.
10. Prepare Frosting: In a mixing bowl, whip the heavy cream until soft peaks form. Gradually add the powdered sugar and continue to whip until stiff peaks form.
11. Frost the Cupcakes: Once the cupcakes are completely cool, pipe the whipped cream frosting onto each cupcake using a piping bag.
12. Top with Crushed Oreos: Finally, sprinkle the tops with the remaining crushed Oreos for an extra touch.

By following these simple steps, you’ll create a batch of delightful Oreo Cupcakes that are sure to impress!
