Gooey Cookies and Cream Bars

I have quite the treat for you today! Chocolate chip Oreo cookie bars. We were doing our usual Sunday baking this past week and planned to make congo bars, but after sifting through the pantry, to my surprise we only had half a cup of chocolate chips. WHAT?!

Well, I looked around some more and I was able to round up some Oreo’s and white chocolate chips and decided I would give it a go. It was the perfect combo. These Oreo bars turned out amazing!

They are soft, gooey and filled with crushed Oreos and chocolate chips in every bite. They reminded me of my favorite cookies and cream cookies, but in bar form. We topped these bad boys with a scoop of vanilla ice cream and we were all in heaven. Love Sundays so much!

Tips for the Best Oreo Bars

  • Line your pan. The last thing you want is for the bars to stick to the bottom of the pan. Lining your pan with parchment or foil is an easy way to make sure this doesn’t happen. I like to leave about 1 inch of overhang for easier removal.
  • Unsalted butter. Using unsalted butter is a great way to control the amount of salt used in this recipe. Each brand of butter adds a different amount of salt to their butter, which could result in saltier baked goods depending on the type you use. To minimize any discrepancy, I use unsalted butter and then add 1/2 teaspoon fine sea salt.
  • Measure the flour. Use the spoon and level technique to measure the flour accurately so that the bars aren’t too dense or dry.
  • Extras on top. Before the bars go in the oven, I like to add more Oreo crumbs and chocolate chips on top of the cookie dough. This not only makes them look prettier, but adds more flavor and texture.
  • Don’t overbake. Remove the bars from the oven when the top is just barely golden brown. They might look a little soft at first, but they’ll set as they cool. Overbaking will cause the bars to dry out.

Let Them Cool

As tempting as it may be to dig in as soon as you pull them from the oven, don’t slice the bars immediately. If you try to slice the bars while they are still warm, it will turn into a gooey mess. They need to cool completely in order for the center to set and become firm. Then you can slice into squares!

Variations

These Oreo cookie bars are easy to customize, so feel free to make them your own. You can use a mix of white + semi-sweet chocolate, or swap both for M&M’s instead. This recipe would also work with any variety of Oreo’s. Double stuff, mint, confetti cake or ultimate chocolate are just a few varieties that would taste delicious!

A cream cheese glaze or powdered sugar icing on top is a great way to add more sweetness. Or a drizzle of melted chocolate or chocolate ganache would make them even more decadent!

After the Oreo bars have cooled, they will stay fresh for up to 3 days at room temperature if stored in an airtight container.

You can also freeze these bars for up to 3 months. Wrap individually in foil, then transfer to a freezer bag or container and store in the freezer. When ready to enjoy, unwrap and let thaw at room temperature on the counter about an hour or so before serving.

FAQs

How can you tell when they’re done?

Once the tops are just barely golden, it’s time to take the bars out of the oven. You can use a toothpick in the center of the bars to make sure it comes out clean. If there is still batter on the toothpick, bake for a few more minutes and try again. Just make sure not to overbake, so they stay soft and chewy.

Are Oreo cookie bars supposed to be gooey?

Yes! What makes these Oreo cookie bars so delicious is the soft and gooey center. That’s why it’s important to remove the bars from the oven while the center is still soft (but cooked through) and the tops are lightly golden. It might look like the centers are undercooked, but they will set as they cool, resulting in the perfectly gooey texture.

Can I double the recipe?

Sure! If doubling for a crowd, use a larger 9×13″ baking pan. You may need to bake for a few minutes longer if the bars are a little more thick. Use a toothpick to test if the center is done before removing.
