Frequently Asked Questions
Can I make these blondies in advance? Yes, definitely. You can bake these a day or two ahead of time. Just make sure to store them in an airtight container at room temperature. They even taste better the next day as the flavors have time to meld together.
What can I use in place of Oreos? If you’re looking for a different flavor, try substituting Oreos with your favorite sandwich cookies. Mint chocolate or peanut butter cookies can add a unique twist to the recipe.
How do I know when the blondies are done? The blondies are done when the edges are firm and begin to pull away from the sides of the pan. The center should be set, but a toothpick inserted should come out with a few moist crumbs for the perfect chewy texture.
These easy Oreo cookies & cream blondie bars are sure to become a favorite in your household just like they have in mine. Whether you’re making them for a special occasion or simply to satisfy your sweet cravings, they’re guaranteed to be a hit. Enjoy baking and indulging in this delightful treat!
