Cookies and Cream Bars have the perfect crinkly top and gooey center packed full of crushed oreo cookies.

This recipe is so simple and straight forward. These Cookies and Cream Bars are a great dessert to throw together last minute because they take very little preparation.

This recipe is very similar to my Brown Butter Blondies with a few small tweaks. These changes make them more like cookie bars than blondies, but both are equally delicious!

What makes these Oreo Bars special?

  • They are so quick and easy to make! I fully believe that all desserts are better when they are simple.
  • You get different textures in every bite. The outside is a bit crunchy while the inside is perfectly gooey and the crushed cookies add another textural element.
  • They can be served warm or cold. They are a versatile dessert that can be served however you choose!

Ingredients for Cookies and Cream Bars:

  • Unsalted butter. I always make sure to use unsalted butter when baking because there is no “standard” for the amount of salt they can add to butter. So if you add salt to a recipe and then use salted butter you could end up with a very salty end product.
  • All-purpose flour. Measuring the flour correctly is very important. I suggest weighing your flour out (I use this scale). If you want to use a measuring cup, make sure you spoon the flour into the cup and level it off with a knife. Don’t use the cup to scoop directly from the flour.
  • Salt. Salt is a must in baked goods. It will help to balance out the sweetness and improve the overall flavor.
  • Baking Powder. This will give the cookies and cream bars some rise
  • Eggs. It will be easier to incorporate the eggs into the batter if they are at room temperature.
  • Vanilla extract. Vanilla is a must in baked goods just like salt. Real vanilla adds a better flavor than imitation vanilla.
  • Brown sugar. Brown sugar adds a chewy texture to the finished product
  • Granulated sugar. This will add sweetness and help us get the texture we are looking for.
  • Oreos. Try not to eat them all before baking!
