4-Fourth Step: Transfer the mixture to the prepared pan. Press firmly and evenly with a spatula or wet hands. This compacts it for dense, soft chewy chocolate chip oatmeal bars. Sprinkle reserved chocolate chips on top and press lightly.

5-Fifth Step: Refrigerate the pan for at least 2 hours, or until firm. No baking needed, which suits hot days or quick prep for students. For extra firmness, chill overnight.
