Step-by-Step Instructions

• Preheat your oven to 350°F (175°C) and line muffin pans with cupcake liners.
• In a large mixing bowl, whisk together the flour, baking powder, baking soda, and salt.
• Cream together the softened butter and granulated sugar until light and fluffy, about 3-5 minutes.
• Add the buttermilk, eggs, and vanilla extract to the butter mixture and mix until smooth.
• Gradually add the dry mixture to the wet ingredients, blending until just combined.
• Gently fold in the chopped Oreo cookies into the batter.
• Fill each cupcake liner about two-thirds full with the batter.
• Bake for approximately 19 minutes, or until a toothpick comes out clean.
• Cool in the pan for 5 minutes before transferring to a wire rack.
