Step‑by‑Step Instructions for Cookie Cheesecake Bars
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven heats up, line a 9×13 inch baking pan with aluminum foil, ensuring there’s some overhang for easy lifting later. Spray the lined foil with nonstick baking spray, creating a slick surface that will help your delicious Cookie Cheesecake Bars release easily after baking.
Step 2: Make the Cookie Crust Base
In a large mixing bowl, beat together 1 cup of unsalted butter, ¾ cup of granulated sugar, and ¾ cup of brown sugar until the mixture is light and fluffy, approximately 2-3 minutes. Add 1 cup of creamy peanut butter, followed by 2 large eggs and 1 teaspoon of vanilla extract. Mix this until everything is well combined and creamy, creating a perfect foundation for your bars.
Step 3: Combine Dry Ingredients
In a separate bowl, whisk together 1 teaspoon of salt, 1 teaspoon of baking soda, 2 cups of all-purpose flour, and 1 cup of quick cooking oats. Gradually add this dry mixture to the wet ingredients, stirring until just combined. You should achieve a thick and doughy texture, indicating that your cookie crust is ready to shine in the Cookie Cheesecake Bars.
Step 4: Add Chocolate Chips and M&Ms
Gently fold in 1 cup of chocolate chips and ¾ cup of M&M’s into your cookie dough mixture. This adds delightful pockets of chocolatey goodness and colorful crunch to your Cookie Cheesecake Bars. Make sure the candies are evenly distributed throughout the dough for balanced flavor in every bite.
Step 5: Bake the Crust
Take half of the cookie dough and press it evenly into the bottom of your prepared baking pan. This layer should be snug but not compacted, creating a delicious crust for the cheesecake layer. Bake in the preheated oven for 5 minutes, just enough to set the crust slightly before adding the creamy cheesecake layer on top.
Step 6: Prepare the Cheesecake Filling
While the crust bakes, prepare the cheesecake layer. In a medium bowl, beat 16 ounces of softened cream cheese until it’s smooth and creamy, about 2 minutes. Gradually add ½ cup of granulated sugar, mixing until well incorporated. Next, mix in 4 ounces of melted semisweet chocolate, and add 2 large eggs one at a time, ensuring each is fully blended without overmixing.
Step 7: Assemble Layers
Once your crust has completed its initial baking, pull it from the oven. Spread the cheesecake batter evenly over the warm crust using a spatula, creating a smooth layer. Crumble the remaining cookie dough on top of the cheesecake layer, ensuring some dollops of dough remain large, adding texture and flavor to your Cookie Cheesecake Bars.
Step 8: Final Baking
Return the baking pan to the oven and bake for an additional 30-35 minutes. Keep an eye on the bars; they are ready when the top is golden brown and the cheesecake is set but slightly jiggly in the center. This slight jiggle is crucial to achieving the perfect creamy texture in your Cookie Cheesecake Bars.
Step 9: Cool and Chill
Once baked, cool the bars in the pan at room temperature for about an hour. After cooling, transfer the pan to the refrigerator and chill for at least 4 hours. This step is essential for firming up the cheesecake layer, making it easy to slice the bars into perfect squares without losing their shape.

Monster Cookie Cheesecake Bars Recipe FAQs
How do I select ripe ingredients for the bars?
Absolutely! For the best results, make sure your eggs are fresh and at room temperature to ensure proper mixing and structure. For the cream cheese, it should be softened to easily blend with the sugars. This results in a creamy and lump-free cheesecake layer that enhances your delicious Cookie Cheesecake Bars.
What’s the best way to store leftover bars?
Oh, very simply! Store your Cookie Cheesecake Bars in an airtight container in the refrigerator, where they will stay fresh for up to 5 days. For longer storage, it’s best to freeze them. Wrap each bar tightly in plastic wrap, then place them in a freezer-safe container. They can last for up to 3 months—just thaw in the fridge overnight before enjoying!
Can I freeze these bars?
Yes, you can! To freeze your Cookie Cheesecake Bars, first let them cool completely after baking. Then, cut them into squares, wrap each piece in plastic wrap tightly, and then place all wrapped bars into a freezer bag or container. This keeps them protected from freezer burn and preserves their deliciousness for about 3 months.
What should I do if my cheesecake layer cracks after baking?
If you see cracks forming, don’t worry—it happens! To prevent this in the future, make sure to mix your cheesecake ingredients on low speed and avoid overmixing, especially after adding the eggs. They should be just combined, and pulling the cheesecake out of the oven while it’s still slightly jiggly will help prevent cracking, too!
Can I modify the recipe for dietary restrictions?
Of course! You can swap out the peanut butter for sunbutter for a nut-free version, or use a gluten-free flour blend in place of all-purpose flour. If you have dairy allergies, a non-dairy cream cheese can also work, though I recommend checking specific brands for the best results.
How long do the bars last in the fridge?
Great question! These delectable Cookie Cheesecake Bars will stay fresh in your refrigerator for up to 5 days when stored properly in an airtight container. Just try to hide them from family members, or they may vanish faster than you can imagine!
