1-First Step: Gather and Prep Your Ingredients Start by pulling together all your ingredients to make the process smooth. Measure out 200 grams of flour, 100 grams of sugar, and the rest as listed, then crush the Oreos into small pieces for even distribution. This mise en place keeps things organized, reducing stress and helping you focus on making chewy Oreo blondies that turn out just right.

2-Second Step: Mix the Dry Ingredients In a large bowl, combine the 200 grams of flour, 1 teaspoon of baking powder, and 50 grams of cocoa powder. Stir them well to ensure even mixing, which is key for the texture in your cookies and cream blondies. If you’re aiming for a gluten-free version, swap the flour now to keep your Oreo bars adaptable from the start.

3-Third Step: Cream the Wet Ingredients In another bowl, beat the 150 grams of softened butter with 100 grams of sugar until it’s light and fluffy, about 2 minutes. Add the 2 eggs and 1 teaspoon of vanilla extract, mixing until smooth. This step builds the base for your chewy blondies, and you can use plant-based alternatives here for vegan Oreo dessert bars.

4-Fourth Step: Combine and Add Oreos Gradually fold the dry ingredients into the wet mixture, stirring until just combined to avoid over-mixing. Gently fold in the 200 grams of crushed Oreos for that signature swirl. At 180 degrees Celsius, your batter will bake into perfect homemade Oreo blondies, and this is a great spot to add extras like chocolate chips for a variation on chocolate chip Oreo blondies.

5-Fifth Step: Bake the Blondies Pour the batter into a greased baking pan and spread it evenly. Bake at 180 degrees Celsius for 25-30 minutes, or until a toothpick comes out clean. Keep an eye on the time to get those fudgy Oreo blondies with the ideal chewy texture, and remember to adjust for high-altitude baking if needed.

6-Final Step: Cool and Serve Let the bars cool in the pan for 10 minutes before cutting into squares. Serve warm for the best flavor, or store for later as I’ll detail. These easy Oreo blondies pair great with ice cream, and for more dessert ideas, check out our peach cobbler dump cake recipe on the blog.
