Equipment

Ingredients

Oreo Cookie Base

12 tablespoons unsalted butter softened
3/4 cup light brown sugar packed
1/2 cup granulated sugar
1 large egg
2 teaspoons vanilla extract
1 1/2 cups all purpose flour
1/2 cup black cocoa powder
1 1/4 cups Oreo crumbs
3/4 teaspoon baking soda
1/2 teaspoon baking powder
1/2 teaspoon salt

Cake Batter Frosting

12 tablespoons butter softened, salted or unsalted (if using unsalted add a pinch of salt to the frosting)
4 cups powdered sugar
1 teaspoons cake batter extract
2 tablespoons milk more or less as needed

Oreo Balls

1/2 cup Oreo crumbs about 5 Oreos
2 tablespoons cream cheese softened
sprinkles for topping

Instructions

Oreo Cookie Base

Preheat oven to 350°F. Line baking sheet with parchment paper. Set aside.
Cream the butter, brown sugar, and sugar on medium speed for 2 minutes. (I use my stand mixer fitted with a paddle attachment. You can use a hand mixer if you prefer).
Add the egg and vanilla extract and mix to combine. Scrape down the sides of the bowl with a rubber spatula.
Add the flour, black cocoa powder, oreo crumbs, baking soda, baking powder, and salt and mix to combine. Scrape down the sides of the bowl as needed.
Portion dough into ¼ cup balls. Place 6 on the baking sheet and press down with the palm of your hand so the dough is a thick disk. Bake 9-11 minutes or until edges are set and centers are no longer shiny.
Remove from the oven and let cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.

Cake Batter Frosting

Make the frosting by creaming the butter, powdered sugar, and cake batter flavoring. Add the milk as needed to reach your desired frosting consistency. Place the frosting in a piping bag and pipe the cookies once they have cooled.

Mini Oreo Balls (optional)

In a small bowl mix the very soft cream cheese and the Oreo crumbs until combined. Portion and roll into small mini balls. These can be made in advance and stored in the fridge in an airtight container for 5-7 days.

Assembly

Frost the cookies then sprinkle the sprinkles over the frosting. Add the small Oreo truffle balls on top. Enjoy at room temperature.

Notes

Store leftover cookies in an airtight container at room temperature for 2 days. If the cookies have the Oreo truffle balls on top, they need to be stored in the refrigerator. Cookies can be stored in the fridge for up to 5 days.

I highly suggest using the cake batter flavoring as this is what gives the frosting and the cookie the "cake batter" flavor and taste. My grocery store carries this flavor, but you can also buy cake batter flavoring on Amazon.
