TIPS FOR MAKING OREO BLONDIES

Prep time: Preheat your oven and prep your baking dish with cooking spray so the Blondies don’t stick. If you don’t have a cooking spray to grease the pan, line it with parchment paper. Cut the parchment paper to size and fold it around the edges to fit. Prepare the cookie pieces by putting the Oreos in the Ziploc bag and breaking them apart on the countertop.
Batter: Add the softened butter, granulated sugar, and brown sugar to your stand mixer and mix it together with a paddle attachment until light and fluffy. It should only take 1-2 minutes. Next, add in the eggs and vanilla extract. Sift together the flour, salt, and baking soda, then add it to the stand mixer on its lowest speed. Fold in the Oreo chunks into the blondie batter with a wooden spoon until just combined.
No stand mixer: If you don’t have a stand mixer to make the blondie batter, add the ingredients to a large bowl in the same order. Use a regular whisk or handheld electric mixer to combine the batter in a mixing bowl.
Baking time: Pour the batter into the baking dish and spread the batter out into an even cookie layer. Put the Oreo Blondies in the preheated oven and bake for 22-25 minutes. Only bake them until golden brown, and take them out before they become too browned and crispy. Let the Blondies cool for a few minutes before slicing.
