Brookie Bars (Brownie & Chocolate Chip Cookie Bars) Cooking Guide

Step 1: Preheat Your Oven
Preheat your oven to 350°F (175°C). This ensures that your Brookie Bars bake evenly.
Step 2: Prepare Your Baking Pan
Line a 9×13 inch baking pan with parchment paper, leaving some overhang to make it easier to lift the bars out later. Grease the parchment paper lightly with non-stick spray.
Step 3: Make the Brownie Batter
In a large mixing bowl, combine 2 cups of sugar and ¾ cup of cocoa powder. Whisk them together until well mixed. Add 1 cup of melted butter and whisk until combined. Next, add 4 eggs and 2 teaspoons of vanilla extract, mixing until the batter is smooth. Gradually fold in 1½ cups of flour and ½ teaspoon of salt until just combined. Be careful not to overmix!
Step 4: Make the Cookie Dough
In another bowl, combine 1 cup of softened butter with 1 cup of sugar and 1 cup of brown sugar. Cream them together until light and fluffy. Add 2 eggs and 2 teaspoons of vanilla, mixing well. In a separate bowl, combine 2½ cups of flour, 1 teaspoon of baking soda, and a pinch of salt. Gradually add the dry ingredients to the wet mixture, stirring until just combined. Fold in 1 cup of chocolate chips for that classic cookie goodness.
Step 5: Assemble the Brookie Bars
Pour the brownie batter into the prepared baking pan, spreading it evenly. Next, dollop spoonfuls of the cookie dough on top of the brownie layer, and gently spread it out to cover most of the surface.
Step 6: Bake
Place the pan in the preheated oven and bake for 30-35 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. Be careful not to overbake!
Step 7: Cool and Serve
Once baked, remove the pan from the oven and allow it to cool in the pan for about 15 minutes. Then, lift the Brookie Bars out using the parchment paper and let them cool completely on a wire rack before cutting into squares.
Budget & Availability Swaps

- Granulated sugar can be replaced with coconut sugar for a lower glycemic index option.
- For the cocoa powder, you can use Dutch-processed cocoa for a smoother flavor.
- Butter can be swapped with a vegan butter alternative if you prefer a dairy-free version.
- All-purpose flour can be replaced with a gluten-free flour blend to accommodate gluten sensitivities.
Pitfalls & How to Prevent Them
- Overmixing the batters can result in tough bars. Mix until just combined.
- Underbaking can lead to gooey centers. Always check with a toothpick and bake until a few moist crumbs stick to it.
- Using too much flour can make the bars dry. Make sure to measure your flour correctly by spooning it into the measuring cup and leveling it off.
Storage & Reheat Guide
Store Brookie Bars in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week. If you want to keep them longer, you can freeze them for up to 3 months. To reheat, simply pop them in the microwave for a few seconds or enjoy them cold — they are delicious either way!
Quick Questions
Can I use brown sugar in the brownie layer?
Yes, you can substitute some of the granulated sugar with brown sugar for a richer flavor and a slightly chewy texture.
How do I know when the Brookie Bars are done baking?
Insert a toothpick into the center. If it comes out with a few moist crumbs, they are ready. If it comes out wet, they need more time.
Can I add nuts to the recipe?
Absolutely! Chopped walnuts or pecans can be a delicious addition to the brownie batter for added texture.
How should I cut the bars for serving?
For clean cuts, use a sharp knife and wipe it clean between cuts. This will keep the edges nice and neat!
