These cookies and cream cupcakes are a dream for Oreo lovers! Covered in a rich and creamy Oreo frosting, these moist chocolate cupcakes guarantee cookies and cream in every bite.
Preheat your oven to 350°Fahrenheit and line a cupcake tin with 12 liners.
In a large bowl, whisk the flour, cocoa powder, sugar, salt, baking powder and baking soda together.
Add in the egg, vanilla extract, oil, milk, and hot water, then mix until the cupcake batter is smooth.
Pour the cupcake batter into the liners, filling up to 2/3 full and bake for 11-15 minutes. A toothpick inserted in the middle should come out clean.
Let cupcakes cool in the pan for 10 minutes, then remove and let cool on a wire cooling rack.
Cookies and Cream Buttercream
Leave the filling in the Oreos and crush them up using a blender or food processor. You can also put them in a ziploc bag and go over them with a rolling pin. Set the crushed Oreos aside. If there are larger pieces, that's okay but you likely will have to spread the frosting rather than use a piping bag because cookie pieces can block the piping tip.
In a medium bowl, use a handheld mixer or standing mixer to mix the butter, vanilla extract, salt, then slowly add in the powdered sugar, ½ cup at a time until it reaches your desired consistency.
If it seems too thick, add in about 1-2 teaspoon of milk to thin it out. Mix in the crushed Oreos.
Once the cupcakes have cooled completely, frost and decorate with more Oreos if desired. Enjoy!
Notes
Note: I highly recommend using a kitchen scale to weigh your dry ingredients. Metric measurements are found above under the "Metric" tab.Cocoa Powder: I recommend using dutch processed cocoa powder, but you can use natural if that's what you have. Measuring Flour and Cocoa Powder: Either measure your flour using a kitchen scale or use the proper scoop and level method: fluff the flour in the bag/container with a fork then use a spoon to scoop the flour into the measuring cup, then run the back of a knife along the top of the cup to even it out. Do the same for the cocoa powder.Storage and Freezing: Once the cupcakes are frosted, store them in an airtight container at room temperature for up to 5 days. You can place any leftover buttercream in the fridge or freezer.Freezing: Let cool completely, then wrap each one individually in plastic wrap and place in a large freezer bag or container. Store in the freezer in a spot where they won't get squished. Use within 2-3 months. Let thaw at room temperature completely before frosting.
