Preparation Steps

• Preheat oven to 350°F (175°C) and line a muffin tin with cupcake liners.
• In a large bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt.
• In a separate bowl, combine the sugar, oil, eggs, buttermilk, and vanilla extract. Mix well.
• Gradually add the wet ingredients to the dry ingredients, mixing until just combined. Do not overmix.
• Fold in the crushed Oreo cookies.
• Fill the cupcake liners about 2/3 full.
• Bake for 20-22 minutes, or until a toothpick inserted into the center comes out clean.
• Let the cupcakes cool in the muffin tin for a few minutes before transferring them to a wire rack to cool completely.
• To make the frosting, beat the butter until creamy. Gradually add the powdered sugar, alternating with the milk, until smooth.
• Stir in the vanilla extract and crushed Oreo cookies.
• Frost the cooled cupcakes and enjoy!
