Ingredients for Cookies & Cream Oreo Blondies
Here’s everything you’ll need to make these irresistible blondies – measure carefully for that perfect texture!
- 1 cup all-purpose flour (spooned and leveled – don’t scoop!)
- 1/2 tsp baking powder
- 1/4 tsp salt (I use kosher)
- 1/2 cup unsalted butter, melted and slightly cooled
- 1 cup packed brown sugar (light or dark both work)
- 1 large egg, room temperature
- 1 tsp vanilla extract
- 10 Oreo cookies, coarsely crushed (about 1 cup)
- 1/2 cup white chocolate chips (optional but delicious!)
Ingredient Notes & Substitutions
Flour: For gluten-free, I’ve successfully used 1:1 GF flour blends. Butter: Dairy-free alternatives work fine, but reduce salt if using salted. Oreos: Crush just enough to keep some chunky pieces – pulverized Oreos disappear in the bake! Chips: Swap white chocolate for dark or milk chocolate, or skip entirely. Egg: Let it sit out 30 mins before baking – cold eggs make the batter seize up.
How to Make Cookies & Cream Oreo Blondies
Okay, let’s get baking! Here’s my foolproof method for making these Oreo-packed blondies:
- Prep your pan: Line that 8×8-inch baking pan with parchment paper, leaving an overhang on two sides – this makes cleanup and removal SO much easier. Give it a quick spray with cooking oil too, just in case.
- Dry ingredients: In your mixing bowl, whisk together the flour, baking powder, and salt until well combined. No lumps allowed!
- Wet ingredients: In another bowl (or just wipe out the first one), mix the melted butter and brown sugar until it looks like caramel sauce. Then beat in the egg and vanilla – don’t skip the vanilla, it makes all the difference!
- Combine carefully: Gradually add your dry ingredients to the wet, folding gently with a spatula until just combined. Overmixing = tough blondies, and we want them chewy!
- Fold in the goodies: Now the fun part – gently stir in those glorious crushed Oreos and white chocolate chips (if using). Leave some bigger Oreo chunks for texture!
- Bake to perfection: Spread the thick batter evenly in your prepared pan. Bake at 350°F for 20-25 minutes until the edges are golden but the center still looks slightly underdone – they’ll continue cooking as they cool.
- Cool completely: Let them cool in the pan for at least 30 minutes before lifting out and cutting. I know it’s hard to wait, but trust me – this prevents crumbly messes!
Tips for Perfect Cookies & Cream Oreo Blondies
My best tricks? Don’t overbake – underdone is better than overdone here. Rotate your pan halfway through baking for even cooking. And for picture-perfect squares, use a hot knife (dipped in hot water and dried) to cut them cleanly. Oh, and always make a double batch – they disappear fast!
Serving & Storing Cookies & Cream Oreo Blondies
Here’s my favorite way to enjoy these blondies – warm them slightly (just 10 seconds in the microwave!) and top with a scoop of vanilla ice cream. The contrast of warm, chewy blondie with cold, creamy ice cream is absolute perfection. For storage, keep them in an airtight container at room temp for up to 3 days (if they last that long!). You can also freeze them for a month – just wrap individual squares in plastic wrap first. They thaw beautifully at room temperature in about 30 minutes, though I won’t judge if you eat one straight from the freezer!
Cookies & Cream Oreo Blondies Variations
Want to mix things up? Try these fun twists on the classic recipe! Peanut butter lovers: Swirl in 1/4 cup of warm peanut butter before baking. Mint chocolate fans: Use mint Oreos instead of regular. Feeling extra? Top with a drizzle of melted white chocolate and extra crushed Oreos right after baking. The possibilities are endless – that’s the beauty of blondies!
Nutrition Information
Just so you know – these nutrition facts are estimates and might change based on your exact ingredients (especially if you go wild with extra Oreos like I sometimes do!). Per blondie: 220 calories, 10g fat (6g saturated), 30g carbs, and just enough deliciousness to make you reach for seconds.
Frequently Asked Questions
Can I use double-stuffed Oreos instead of regular? Absolutely! The extra cream filling makes them even richer – just be gentle when crushing so you keep those nice big chunks. You might want to reduce the white chocolate chips slightly since double-stuffed Oreos are sweeter.
How do I know when the blondies are done baking? Look for golden edges that are just starting to pull away from the pan, but the center should still look slightly underdone. The toothpick test works too – you want a few moist crumbs clinging to it, not wet batter.
Why did my blondies turn out cakey instead of chewy? Oh no! This usually happens if you overmixed the batter or used too much flour. Next time, mix just until combined and spoon-and-level your flour carefully. Also, don’t overbake – they firm up as they cool!
Can I make these without eggs? I’ve had success using a flax egg (1 tbsp ground flax + 3 tbsp water) for a vegan version, though the texture is slightly denser. The blondies will still taste amazing with all those Oreos!
Help – my Oreos sank to the bottom! No worries – just toss your crushed Oreos with a teaspoon of flour before folding them in. This little trick helps them stay suspended throughout the blondies beautifully.
