Oreo Blondies Recipe: Chewy Oreo-Stuffed Blondie Bars

Chewy blondies filled with chopped cookies – these Oreo blondies are seriously addictive. They’re easy to make, moist with crinkly tops, and perfect for anyone who loves cookies and cream!

Seriously Addictive Oreo Blondies

These Oreo blondies are chewy and moist with a glossy, crinkly top—similar to a favorite brownie but with a buttery vanilla base. Chopped Oreos folded into the batter add crunchy bits and pockets of sweet cream that break down slightly as you mix, creating a cookies-and-cream texture in every bite. They’re less dense than Oreo-stuffed brownies but deliver a stronger Oreo flavor thanks to the chopped cookies mixed throughout.

Ingredients you’ll need

This recipe uses just a few pantry staples:

• 1 cup unsalted butter, melted (you can use salted butter and omit added salt)
• 1 1/2 cups light brown sugar (or 3/4 cup dark brown sugar + 3/4 cup granulated sugar if you don’t have light brown)
• 2 teaspoons vanilla extract
• 2 large eggs
• 2 1/4 cups all-purpose flour
• 1/2 teaspoon salt
• About 20–24 Oreos, chopped (roughly 2 cups)

Note about brown sugar: Light brown sugar contributes a caramel flavor and chewiness. Avoid substituting all granulated sugar, which can make the bars crispier and less flavorful. Use 1 1/2 cups light brown sugar or the split substitution above.

Making the blondies

This is a one-bowl, no-mixer recipe. Quick overview:

1. Preheat oven to 350°F (180°C, or 160°C fan). Line a 9×13-inch (23×33 cm) pan with parchment (leave an overhang) or lightly grease it.
2. Melt the butter in a large bowl, then whisk in the brown sugar until the mixture looks uniform and the butter is fully incorporated.
3. Whisk in the eggs and vanilla until smooth and free of streaks.
4. Fold in the flour and salt gently; whisk if you see lumps of flour.
5. Stir in the chopped Oreos, keeping a mix of larger pieces and crumbs for texture.
6. Spread the batter evenly in the prepared pan.
7. Bake 25–30 minutes, until the top is set and a toothpick comes out clean or with a few moist crumbs.

Pro tip: Cool completely before slicing for clean edges. If you used parchment with an overhang, lift the cooled slab from the pan and slice on a cutting board with a sharp knife.

Why these blondies stand out:

• Super chewy texture
• Moist center with crinkly tops
• Buttery vanilla flavor with a hint of brown sugar
• Packed with chopped Oreos for a cookies-and-cream experience
• Very simple to prepare

Equipment

• 9×13 inch (23×33 cm) baking pan

Recipe

Ingredients

• 1 cup unsalted butter (226 g), melted
• 1 1/2 cups light brown sugar (350 g), lightly packed
• 2 large eggs
• 2 teaspoons vanilla extract
• 2 1/4 cups all-purpose flour (about 281 g)
• 1/2 teaspoon salt
• 2 cups chopped Oreos (about 20–24 cookies, depending on how finely you chop them)

Instructions

1. Preheat the oven to 350°F (180°C; 160°C fan). Grease a 9×13-inch pan or line it with parchment leaving an overhang.
2. Whisk the melted butter and brown sugar in a large bowl until smooth and fully combined.
3. Add eggs and vanilla, whisking until the mixture is uniform with no streaks.
4. Gently stir in the flour and salt, whisking briefly to remove any lumps.
5. Fold in the chopped Oreos; some pieces will break apart, and that’s fine.
6. Spoon the batter into the prepared pan and smooth the top.
7. Bake 25–30 minutes, until the top is set and a toothpick has a few moist crumbs or comes out clean.
8. Cool completely before slicing. If lined with parchment, lift the bars from the pan using the overhang and cut on a board with a sharp knife.

Notes

1. Butter: Salted butter can be used—omit added salt in the recipe if you do.
2. Brown sugar: If you don’t have light brown sugar, substitute 3/4 cup dark brown sugar plus 3/4 cup granulated sugar. Do not replace light brown sugar entirely with granulated.
3. Storage: Store in an airtight container at room temperature up to 4 days. Freeze cooled bars up to 2 months; thaw overnight in the fridge and bring to room temperature before serving.
4. Nutrition: Nutrition values are estimates per bar assuming 18 equal pieces.
