3/4 c. granulated sugar
2 t. vanilla extract
1/2 c. sour cream, at room temperature
1/2 c. unsweetened cocoa powder
3/4 cup all-purpose flour
1/2 t. baking soda
1 t. baking powder
1/4 t. salt
Oreo Buttercream:
1 c. unsalted butter, at room temperature
4 c. powdered sugar, divided
20 Oreo cookies, finely crushed
4 T. milk

Chocolate Cupcakes:
Preheat oven to 350 degrees. Prepare 1-2 muffin pans with cupcake liners.
Melt butter and chocolate together in the microwave in a microwave safe bowl in 30 second increments, stirring in between intervals; set aside.
In the bowl of a stand mixer with the whisk attachment, add eggs, sugar, vanilla and sour cream; whisk on medium speed until smooth for about 1 minute.
In a medium-sized bowl, sift cocoa powder, flour, salt, baking soda and baking powders together until thoroughly combined. Add cooled butter and chocolate to the stand mixer; whisk until smooth, about 30 seconds. Slowly add in flour mixture, about 1/4 c. at a time, with mixer on low speed. When finished adding the flour, turn the mixer off to ensure that it isn't over-mixed. The batter will be very thick. Fill cupcake liners with batter 2/3 full.
Bake 15-18 minutes. The center of the cupcake should spring back up if gently pressed.
Oreo Buttercream:
In the bowl of an electric mixer, beat butter until light and smooth. Slowly add half of the powdered sugar; mix until smooth. Scrape the sides of the bowl, as necessary. Add remaining powdered sugar; mix until combined.
Fold in crushed Oreo cookies; mix until smooth, reserving some for the topping. Add in milk, 1 T. at a time, until reaching the consistency. Use an ice cream scoop to drop a scoop onto each cupcake.
Topping:
Top with crushed Oreo cookies, hot fudge, or chocolate sauce, if desired.
Makes 12-24 cupcakes.
