Common Mistakes to Avoid
A few common mistakes can ruin your Oreo Dump Cake experience. Here are some tips to help you avoid them.
- Bold Layering: Skipping the layers can lead to uneven textures. Make sure to layer the Oreos, condensed milk, and Cool Whip properly for that gooey effect.
- Bold Mixing: Mixing the ingredients after layering will disrupt the texture. Avoid stirring once you’ve topped with butter; let the oven do its magic.
- Bold Overbaking: Baking too long can make your cake dry instead of gooey. Keep an eye on it and remove it when the top is bubbly and slightly crisp.
- Bold Ingredient Quality: Using low-quality ingredients can affect flavor. Always opt for fresh, quality products, especially for the Oreos and Cool Whip.
- Bold Cooling Time: Serving immediately may result in a hot mess. Allow the cake to cool for a few minutes before serving to improve consistency.
