Expert Tips
Expert Tip: If you want to be able to cleanly cut these Halloween cake bars. I recommend that you line your cake pan with parchment paper, making sure to allow the parchment to overlap the edges. This way once it's cool, you can remove all the bars from the pan easily and then slice them.

Variations
Do you want to change up this recipe?
- I used multi-color Halloween sprinkles, but you can use just orange sprinkles if you want an all-orange Halloween Oreo Cake bar.
- Usually, I use an offset spatula to press these cookie bars into the 9-inch baking pan because I find it works well to smooth them out.
- If you want to add more flair to these cake bars you can place some Halloween M&M's on top of the Oreos before you bake these bars.

I am confused as to what size pan to use. Is it a 9x9 or 9x13?
