Oreo Ice Cream Cake

I've never made this but I tasted a bit, that was all that was left, and it was really good. It only has 4 ingredients and sounds super easy to make. I think you could easily substitute homemade sauce for the hershey's. I think it would be great to take to a potluck because you wouldn't have to worry about keeping it warm or making sure it doesn't spill on the way there.

• Ready In: 2 hrs 10 mins

1. Grease a 9x13" pan.
