These easy baking steps will guide you through creating perfectly chewy, chocolatey Oreo cookie bars every time, great for anyone who loves a giant Oreo cookie vibe in bar form.
Preheat the oven: Set your oven to 350°F and line an 8x8-inch baking pan with parchment paper for easy removal.
Cream the butter and sugars: In a large bowl, mix the butter, brown sugar, and granulated sugar until light, fluffy, and well combined.
Add the wet ingredients: Mix in the eggs, vanilla extract, and salt until everything is smooth and fully incorporated.
Combine with the dry ingredients: Add the flour and stir just until the dough comes together, avoid overmixing to keep the bars soft.
Fold in the mix-ins: Gently fold in the mini chocolate chips, Christmas M&M's, and crushed Oreos, saving a little extra for topping.
Press the base layer: Press about one-third of the cookie dough evenly into the bottom of your prepared baking pan.
Layer the whole Oreos: Arrange the 9 whole Oreos in a single, even layer over the dough.
Add the remaining dough: Spread the remaining cookie dough over the Oreos, gently pressing to cover them completely.
Add decorative toppings: Sprinkle a few extra crushed Oreos and M&M's on top for a festive finish.
Bake the bars: Bake for 22-25 minutes, or until the top is golden and a toothpick inserted into the center comes out mostly clean.
Cool and slice: Let the bars cool in the pan for 10-15 minutes before slicing into squares and serving.
Pro Tips for Making the Best Oreo Cookie Bars
These simple tips help ensure your Oreo cookie bars turn out perfectly soft, chewy, and full of holiday flavor.
For the chewiest, most flavorful bars, start with room-temperature butter so it creams smoothly with the sugars, creating that ideal texture. When adding the flour, mix only until the dough comes together to avoid a dense result.
Saving a little extra crushed Oreos and M&M's for the top adds a festive look and a satisfying crunch after baking. Using parchment paper is a small step that makes lifting and slicing the bars incredibly easy.
If you like gooier cookie bars, remove them from the oven when the edges are set but the center still looks slightly soft. Letting them cool before slicing helps the bars firm up and gives you clean, even squares.
Storing and Reheating Tips for Oreo Cookie Bars
These Oreo cookie bars keep well and stay delicious for days.
Store them in an airtight container at room temperature for up to four days or refrigerate for a slightly firmer texture. They also freeze well for up to two months, just thaw at room temperature before serving. For a warm, fresh-baked bite, microwave a bar for about 8-10 seconds to soften the center and melt the chocolate again.
Delicious Variations for Oreo Cookie Bars
There are so many fun ways to customize these bars to match any theme or season-whether you're making Santa Oreo Cookie Bars, Christmas Oreo Cookie Bars, or your own version of loaded M&M Oreo cookie bars.
Try swapping the Christmas M&M's for peanut butter chips or white chocolate chips to change the flavor. You can use different Oreo varieties like peppermint, golden, or double-stuffed to give the bars a unique twist.
For an extra-rich version, drizzle melted chocolate over the top or swirl in a bit of fudge or caramel before baking. If you love texture, add chopped pretzels or toasted nuts for a sweet-and-salty crunch.
Each variation adds its own personality while keeping the bars incredibly soft and chewy.

FAQ
Yes! Regular Oreos work perfectly in these Oreo cookie bars. You'll still get the same delicious flavor and cookie pieces throughout the dough. The Christmas version simply adds extra color and a festive look.
Absolutely. If you want more Oreo flavor blended into the dough, crush Oreo cookies into smaller crumbs. If you prefer bigger cookie pieces, leave some larger chunks so the bars have more texture.
No, it's optional, but highly recommended. The whole Oreo layer adds a fun surprise when you slice the cookie bars, and it gives the center a soft, creamy cookie texture that tastes amazing.
Yes! Mini chocolate chips mix more evenly into the dough, but regular chocolate chips or even white chocolate chips will still work beautifully in this recipe.
This usually happens when the bars are baked too long or the dough is overmixed. For soft, chewy Oreo cookie bars, bake just until the edges are golden and the center looks slightly set. Overmixing breaks down the dough structure, making it dry.
If the center sinks slightly, that's usually due to underbaking or spreading the top layer too thin. The bars will still taste great, just let them cool completely so they set properly before slicing.
Let the cookie bars cool thoroughly, then refrigerate them for 15-20 minutes. Use a large, sharp knife and wipe between cuts. This helps keep chocolate chips and cookie pieces from smearing.
