These soft and chewy homemade Oreo cookies use devil’s food cake mix as a base to keep them extra fudgy and super simple to make. They are filled with cream cheese frosting and taste amazing with a tall glass of milk.
Line a baking sheet with parchment paper or a silicone baking mat (or spray with nonstick cooking spray) and set aside.
In the bowl of a stand mixer, add the cake mix, eggs, and oil. Mix on low speed using the paddle attachment until fully combined.
Scoop and roll the dough into 1" balls, then place them onto the prepared baking sheet about 3" apart.
Bake in a preheated oven for 8-10 minutes, or until the cookies are lightly brown and set on the edges. (Tip: once the cookies are puffed and cracked on top, cook for 1 more minute)
Remove from the oven and let the cookies cool on the pan for 2-5 minutes before transferring to a wire rack to cool completely while you make the frosting.
In the bowl of a stand mixer, add the room temperature butter and room temperature cream cheese. Beat with the whisk attachment until light and fluffy, or about 2-3 minutes. Turn off the mixer and add the powdered sugar and vanilla. Mix on low until fully incorporated, then beat on high for about 30 seconds until it is light and fluffy again.
Transfer frosting to a piping bag with a large round tip and pipe frosting over half of the cookies. If desired, add sprinkles to the edges before you top with another cookie.
Serve cookies immediately, freeze, or store in an airtight container for up to 3 days. Enjoy!
