How to Make Oreo Brownie Blondie Bars: An Amazing Ultimate Recipe
Step 1: Prepare Your Oven and Pan
The key to success starts with properly preparing your baking environment. Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish thoroughly. This ensures the bars don’t stick and makes removing them easier when they’re baked to perfection.
Step 2: Mix the Wet Ingredients
In a large bowl, whisk the melted butter, brown sugar, and granulated sugar together until smooth and glossy. This step is crucial because it creates a velvety base that makes the bars tender with a lovely caramel undertone from the brown sugar.
Step 3: Add Eggs and Vanilla
Beat in the eggs one at a time to ensure complete incorporation. Then stir in the vanilla extract. This combination builds the structure and layers in that classic sweet almond scent you expect in any great Blondie.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking powder, and salt. Mixing these separately ensures even distribution so your bars bake evenly without any surprises.
Step 5: Bring Wet and Dry Ingredients Together
Gradually add the dry ingredients to your wet mixture, stirring just until everything is combined. It’s important not to overmix here; a gentle hand guarantees the perfect tender crumb without toughness.
Step 6: Fold in Chocolate Chips and Crushed Oreos
Gently fold in semi-sweet chocolate chips and the crushed Oreos. These add delightful bursts of flavor and texture, giving every bar its signature Oreo Brownie Blondie Bars: An Amazing Ultimate Recipe appeal with pockets of melty chocolate and cookie crunch throughout.
Step 7: Bake to Perfection
Pour the batter evenly into your prepared pan and bake for 25 to 30 minutes. You’re looking for a golden top and a toothpick inserted in the center to come out clean. This step seals the deal, creating bars that are crisp on the outside and chewy inside.
Step 8: Cool and Add Optional Toppings
Once baked, let the bars cool in the pan for 15-20 minutes. If you want to kick these up a notch, sprinkle some additional crushed Oreos on top right before serving for some stunning presentation and extra crunch.

Make Ahead and Storage
Storing Leftovers
Leftover Oreo Brownie Blondie Bars store beautifully in an airtight container at room temperature for up to 3 days. Just make sure to keep them covered well to maintain their soft, chewy texture and prevent them from drying out.
