- Monitor baking time: Every oven is different. Check your cake at the 40-minute mark to avoid overbaking.

Common Mistakes to Avoid
When making Oreo Dump Cake, it’s easy to make some common mistakes that can affect the final result. Here are a few to watch out for:
- Skipping the greasing step: Not greasing your baking dish properly can cause the cake to stick. Always grease it with butter or non-stick spray before adding ingredients.
- Overmixing the cake mix: Mixing the cake mix too much can lead to a dense texture. Just sprinkle it evenly over the Cool Whip without stirring.
- Using cold ingredients: Cold ingredients may not blend properly, leading to uneven baking. Ensure your Cool Whip is fully thawed and other ingredients are at room temperature.
- Not letting it cool: Cutting into the cake immediately after baking can result in a messy serving. Allow it to cool for at least a few minutes before digging in.
- Neglecting portion size: Serving oversized pieces may overwhelm your guests. Cut smaller portions, especially since this dessert is rich!
