Why you’ll love them

All the right kinds of chewy, dense and sweet, these Oreo blondies are absolutely scrumptious.

The texture is just right with a dense, rich and soft centre and chewy edges. It’s all sandwiched between an Oreo cookie base and pieces of cookie on top. So, with a crunchy base, crunchy bits on top – it’s like texture overload in the very best way.

How about the flavour? Well, these Oreo blondies are buttery, sweet and creamy with a hit of chocolate cookie. The batter has just a hint of white chocolate which adds to that creamy flavour.

They’re extra indulgent and comforting when warm so do yourself a favour and give them a short burst in the microwave to warm them slightly and you’ll be in blondie bliss!

And if you’re a true blondie lover, you should definitely try these Macadamia Caramel Blondies and Raspberry Chocolate Chip Blondies too.

Ingredients in cookies and cream blondies

You should have most of these everyday ingredients in your pantry already.

  • Oreos: I use regular Oreos in these blondies but, to be honest, you could use any cream filled cookie, or any flavour of Oreo.
  • Eggs: Eggs help with the texture, flavour and structure.
  • White chocolate: There isn’t a lot of white chocolate in these blondies – just enough to add fudgy texture and add a little creaminess to the flavour to give that real cookies and cream flavour. White chocolate in block form or white chocolate chips will both work though blocks normally melt a little easier.
  • Sugar: I use white and brown sugar in these. Brown sugar has added moisture and adds chewiness to the brownies.
  • Butter: I use unsalted but you could use salted and get a nice sweet and salty flavour, though I’d leave out the additional salt in this case.
  • Baking powder: Blondies don’t need a lot of lift as you don’t want to lose the fudgy texture, so just a little baking power is perfect.
  • Vanilla: Adding some vanilla extract adds to the cookies and cream flavour.
  • Flour: All you need is plain flour / all-purpose flour.
  • Salt: Only add this if you are using unsalted butter.

  1. The Oreo base: Blend or process Oreos to crumbs, then mix in a little melted butter. Press the mixture into the base of a lined 8 inch square pan (photo 1).
  2. The batter: First whisk together the dry ingredients, then add the wet ingredients (photo 2) and mix it all together. Spread the blondie batter over the Oreo base (photo 3).
  3. The topping: Add some chopped Oreo cookies to the top (photo 4) and gently nudge them down into the batter, then bake.

Tips and tricks

  • The melted butter and chocolate: Make sure both the melted butter and chocolate have cooled slightly. You don’t want to add them to the batter whilst hot. Warm is fine.
  • Let them cool in the tin: This gives them time to do their final cooking as they cool and allows them to set nicely.
  • Cut them when they’ve cooled: If you try to get them out of the tin while they’re still warm, Oreo blondies can break into pieces – albeit delicious pieces. Let them cool completely before removing them from the tin and cut with a very sharp knife.
  • Use an 8 inch tin: A smaller or larger tin will adjust the cooking time and you may end up with undercooked or cakey blondies as a result.
  • Want even more Oreos? No problem – feel free to add 2-3 more Oreos to the top or even into the batter.

Storing your blondies

Keep your Oreo blondies perfectly soft by storing them in an airtight container in a cool placed, like the pantry.

These are best eaten at room temperature or slightly warm. Wherever you store them, pantry or fridge, do yourself a huge favour and heat them in the microwave for 10 to 20 seconds – 10 for room temp and 20 for fridge cold. This makes them taste extra indulgent and totally comforting

They’re best eaten within 3-4 days but can also be frozen very successfully.

  1. I use a standard Australian 20ml tablespoon (4 teaspoons worldwide)
  2. For best results you should always weigh ingredients like flour and sugar. Kitchen scales like these are relatively cheap but if you can’t weigh the ingredients, use the spoon and level method (don’t scoop).
  3. All ovens vary. What takes 40 minutes in my oven may take 35 or 45 in yours. Many ovens also don’t heat evenly or may even run hot or cold so it’s a good idea to keep an oven thermometer in the centre of your oven at all times. They’re very cheap and are a good back up.
