      Tessa’s Recipe Overview

      Flavor: A delightful combination of chocolate and butterscotch tastes.

      Texture: Rich, chewy, and slightly gooey.

      Simplicity: Each layer's batter is straightforward (no mixer required!), though creating two desserts in one takes a bit of time.

      Why you’ll enjoy this recipe: It merges two beloved desserts into one!

      Cookies and brownies rank among my favorite treats and are also some of the most popular recipes I have.

      Many brookies tend to favor one element too heavily. Either the brownie dominates entirely or the cookie layer turns out dry and flavorless. Alternatively, if you merely layer one on top of the other, they can lack visual allure!

      In my extensive recipe trials, I experimented with:

      - Thicker versus thinner cookie bases

      - Four different assembly and stacking methods

      - Various baking temperatures

      I discovered that placing the cookie on top compressed the brownie layer, resulting in uneven baking. Moreover, they appeared very much like blondies from above. Since we do eat with our eyes, I aimed for something that would stand out on the dessert table.

      My key insight? Positioning the cookie dough at the bottom for optimal texture and saving some for the top to enhance visual appeal!

      Recipe Ingredients

      Butter (for both layers): Using melted butter keeps both layers chewy and dense, eliminating the need for an electric mixer. Creaming butter would result in a more cake-like cookie layer.

      Brown sugar (cookie layer): Contributes moisture and chewiness.

      Granulated sugar (brownie layer): When vigorously whisked in after adding eggs, it helps to form that classic shiny, crackly brownie top.

      Eggs (both layers): An additional yolk enhances richness and ensures the brownie layer remains fudgy rather than cake-like. I haven’t found an adequate egg substitute for this recipe.

      Cocoa powder (brownie layer): Dutch-processed cocoa provides a smoother and richer chocolate flavor, but natural cocoa will work perfectly as well. Refer to my cocoa powder guide for details.

      Oil (brownie layer): This is essential. Using just butter made the brownies stale more quickly. A bit of oil keeps them soft and fudgy for several days.

      Cornstarch (brownie layer): Only 2 teaspoons make the brownie layer particularly tender without making it cake-like.

      Chocolate chips (both layers): Don’t omit this! They help achieve a shiny crust on the brownies and provide an additional texture contrast and visual appeal.

      How to Make Brookies (Step by Step)

      1. Prepare the layers. Make both the cookie dough and brownie batter.

      

      2. Spread the cookie dough. Scoop nine balls of cookie dough and press the remaining dough into a parchment-lined 8-inch metal pan.

      3. Spread the brownie batter. Evenly distribute the brownie batter over the cookie dough.

      4. Add the remaining cookie dough on top. Flatten the scoops in your palms and place them over the brownie batter.

      5. Bake. Set the oven to 325°F and bake for 33-38 minutes: 33 minutes for gooey, fudgier centers or 38 minutes for a firmer, chewier texture.

      6. Let cool. Allow to cool completely before slicing and serving. This helps the bars set and the flavors meld.

      Tessa’s Recommendations

      - Use a metal pan for uniform baking (glass or ceramic may need an additional 5-10 minutes).

      - Whisk the eggs into the brownie batter for a full minute for a glossy crust.

      - Avoid overbaking to prevent dry edges.

      - Accurately measure flour to ensure the desired texture.

      - Cool completely for clean slices, a chewier texture, and a well-rounded flavor.

      - Use high-quality cocoa powder; Dutch-processed cocoa is my preferred choice for a smoother taste.

      Storage & Preparation Ahead of Time

      - Room temperature: Keep in an airtight container for up to 3 days.

      - Refrigerator: Good for up to 4 days (bring to room temperature before serving if you prefer a softer texture).

      - Freezer: Freeze sliced bars for up to 2 months.

      Test Kitchen Observations

      This recipe went through countless iterations to perfect it. Initially, I experimented with different ratios of brownie and cookie layers until achieving the right balance. Then, I explored various layering techniques.

      Brownie on Top

      After finalizing the ratios, my first attempt had the cookie layer below with the brownie on top. Unfortunately, the cookie was completely hidden from above!

      Cookie on Top

      When I tried layering cookie dough on top, it spread and concealed most of the brownie, compressing the brownie layer and creating an uneven texture.

      Leavening

      Once I decided to place the cookie dough at the bottom and add a bit on top, I tested whether incorporating baking soda would enhance the outcome. It didn’t!
