Get ready to enjoy the best homemade cookie out there! These Oreo cakesters are perfectly soft on the outside and filled with the BEST creamy, oreo filling. You won't be able to stop at just one!
Preheat the oven to 350°F and line two baking sheets with parchment paper. Set aside.
Add the cake mix, oil and eggs to a large bowl. Use a hand mixer or a stand mixer to combine. If a darker cookie is desired for that Oreo look, add a few drops of black food coloring until the desired color is achieved.
Use a medium cookie scoop to scoop dough onto the prepared baking sheets, leaving 2 inches between them. Bake for 11-12 minutes, until the edges of the cookies are set. Let them cool for 2 minutes on the baking sheet before transferring to a cooling rack to cool completely.
Filling
In a medium bowl, beat the cream cheese and butter together until smooth. Add the powdered sugar, salt, and vanilla and beat again until fully combined.
Add the filling to a piping bag or a ziplock bag and snip off the end for a medium sized opening. Squeeze a dollop of frosting on the backside of one cookie and sandwich another on top. Repeat with the rest of the cookies.
