How to Make Halloween Oreo Cake Bars Step-by-Step

Step 1: Preheat oven to 350F. Line a 9×13″ baking dish with parchment paper.
Step 2: In a large mixing bowl, combine cake mixes, milk, oil, and eggs. Use an electric mixer to beat until fully incorporated. The batter will be thick.

Step 7: Add remaining chopped Oreos to the top of the batter, and use your fingers or spatula to press the cookies gently into the batter.
