this is a Remix off of the homemade Oreo Cookie by In The Kitchen With Matt. He has his own instructable so go look at his too. https://www.instructables.com/id/Easy-Homemade-Oreo-Cookies/

Ingredients

entire yellow cake mix

1/3 cup of canola or vegetable oil (78ml)

2 large eggs

1lb (16oz) or 453 g of Powdered Sugar

1/2 cup of unsalted softened butter (115g)

4 oz of softened cream cheese (can use 8 oz as well) (115g)

1 tsp. of vanilla extract (5ml)

Chocolate chips (as much as you want to put in)

Tools

Hand mixer or Stand Mixer

Bowls

Spatula

Spoon or Scoop

Cookie Sheet

Ziplock bag

Step 1: Mix Eggs and Oil

First preheat the oven to 350 degrees F. Then we mix together our eggs and our oil in a large bowl, using a hand mixer, whisk, or stand mixer.

Step 2: Add Cake Mix

Next, we add the entire cake mix and chocolate chips into the large bowl then we are gonna mix it again with a hand mixer, whisk, stand mixer, or if you want you can use a wooden spoon. Mix until completely combined into one substance.

Step 3: Scoop and Ball Up the Dough

Next, we want to scoop out the dough into a ball shape that is as big as a ping pong ball. When we have made all of our dough into balls then we bake them in the oven for 10 - 12 minutes.

Step 4: Cool the Cookies

Once our cookies are out of the oven and look like this, we have to let them cool on the cookie sheet for a few minutes.

Step 5: Make the Filling

Next, we have to make our filling. Add the cream cheese, butter, vanilla extract, and powdered sugar into a bowl then we mix them together really well.

Step 6: Pipe the Filling

Next, take a ziplock bag and place it into a glass, then add the filling to the bag(we are making a piping bag). Next push the filling into one corner, then twist the other end a few times, keeping the filling at the corner.

Step 7: Finishing Touch

Now just snip off the corner with some scissors and you go yourself a piping bag. Then gently squeeze out the filling onto a cookie. Then place another cookie gently on top of the filling that you just placed on the cookie. Now you should have the homemade oreo cookie. Enjoy!
