How to Make Brownie Cookie Bars
Step 1: Preheat and Prepare
First things first, let’s get that oven roaring! Preheat it to 325°F. While it heats up, grab a 9×13 metal pan and line it with parchment paper. This is a crucial step that helps with easy removal and clean-up later. Trust me, your future self will thank you for it!
Step 2: Prepare the Brownie Mix
Now, let’s dive into the brownie mix! Follow the package instructions to whip up your brownie batter. This usually involves mixing the brownie mix with oil, water, and eggs. Once it’s smooth and silky, pour it into your prepped pan. This fudgy base is a game-changer and sets the stage for our cookie layer!
Step 3: Make the Cookie Dough
Now for the cookie dough—where the magic happens! In a mixing bowl, combine the melted butter, light brown sugar, granulated sugar, and eggs. Stir until everything is well blended. The creamy and luscious mixture is what gives these Brownie Cookie Bars their delightful chewy texture. Don’t skip this step, it’s where the flavor originates!
Step 4: Combine Dry Ingredients
It’s time to mix in our dry ingredients! Add the all-purpose flour, baking soda, and salt to the wet mixture. Gently fold everything together until no dry spots remain. Remember, over-mixing is the enemy! We want to keep that cookie dough tender and soft, creating the perfect contrast to our fudgy brownies.
Step 5: Add Chocolate Chips
Let’s bring in the star of our show—the chocolate chips! Gently fold them into the cookie mixture until they’re evenly distributed. These little gems will melt slightly during baking, creating gooey pockets of chocolatey goodness. Be careful not to over-mix; we want those surprises throughout, rather than a uniform chocolate flavor!
Step 6: Assemble and Bake
Now comes the fun part—combining everything! Using rounded tablespoons, drop dollops of cookie dough on top of the brownie batter, pressing them down lightly. Be sure not to cover the brownie batter completely for that beautiful layered effect. Bake these delicious bars for about 25-30 minutes, or until a toothpick comes out almost clean. Your kitchen will smell heavenly!

Tips for Success
- Make sure your butter is cooled before mixing; it prevents the eggs from scrambling.
- Use parchment paper for effortless bar removal and clean-up.
- Don’t skip the egg yolk! It adds richness and moisture to the cookie layer.
- Experiment with different chocolate types for unique flavor combinations.
- Let the bars cool completely before cutting for clean edges.
Equipment Needed
- 9×13 metal pan: A glass baking dish is a great alternative if you don’t have metal.
- Parchment paper: If you’re out, you can simply grease the pan well with butter or oil.
- Mixing bowls: Any large bowl will do; I love using my trusty glass mixing bowl.
- Measuring cups & spoons: Alternatively, use a kitchen scale for precise measurements.
- Spatula: A standard spatula works fine, but silicone spatulas help scoop every last bit.
Variations of Brownie Cookie Bars
- Nutty Delight: Add chopped nuts like walnuts or pecans for extra crunch and flavor.
- Blondie Twist: Swap the brownie mix for a blondie mix for a caramel-like flavor.
- Minty Fresh: Incorporate mint chocolate chips for a refreshing chocolate-mint combination.
- Gluten-Free Option: Use a gluten-free brownie mix and substitute all-purpose flour with a gluten-free blend.
- Dairy-Free Delight: Replace butter with coconut oil and use dairy-free chocolate chips for a vegan treat.
- Fruit Fusion: Fold in some dried fruits like cranberries or raisins for a hint of tartness.
Serving Suggestions for Brownie Cookie Bars
- Pair with vanilla ice cream for a delectable dessert sundae.
- Drizzle with warm caramel sauce for an extra touch of indulgence.
- Serve alongside a steaming cup of coffee or a tall glass of milk.
- Garnish with fresh berries for a pop of color and freshness.
- Wrap individual bars in parchment for a delightful gift or snack on the go.
FAQs about Brownie Cookie Bars
Curious about these scrumptious Brownie Cookie Bars? Here are some FAQs that might help you whip up the perfect batch!

Absolutely! If you have a favorite homemade brownie recipe, feel free to use it. Just make sure it yields the right amount for a 9×13 pan for the best results.

Store your Brownie Cookie Bars in an airtight container at room temperature for up to three days. For longer storage, wrap them tightly and freeze for up to three months.

Check for doneness by inserting a toothpick two inches from the side of the pan. If it comes out almost clean, it’s time to take them out. Remember, they’ll set as they cool!

Certainly! You can reduce the granulated sugar a little if you’d like a less sweet treat, or use a sugar substitute for a healthier option. Just keep in mind it may slightly change the texture.
