Step-by-Step Instructions
Making Chocolate Chip Cookie Brownie Bars is easy and fun since it all comes together in one pan!
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that your bars will bake evenly and thoroughly.
Step 2: Prepare the Pan
Grease a 9×13 inch baking pan or line it with parchment paper for easy removal. This step is important to prevent sticking.
Step 3: Make the Brownie Layer
In a bowl, mix softened butter, granulated sugar, brown sugar, eggs, and vanilla until smooth. Add cocoa powder, flour, baking soda, and salt, mixing just until combined. Pour this brownie batter into the prepared pan, spreading it evenly.
Step 4: Make the Cookie Layer
In another bowl, cream together softened butter, brown sugar, granulated sugar, egg, and vanilla extract until fluffy. Blend in flour, baking soda, and salt until combined. Fold in chocolate chips.
Step 5: Layer the Cookie Batter
Carefully drop spoonfuls of the cookie batter over the brownie layer. Gently spread it out, leaving some brownie visible underneath for a marbled effect.
Step 6: Bake the Bars
Bake in the preheated oven for 25-30 minutes, until the edges are set and a toothpick inserted into the center comes out with a few moist crumbs. This helps ensure that both layers are perfectly cooked.
Step 7: Cool and Slice
Remove the bars from the oven and let them cool in the pan for at least 15 minutes. Once cooled, slice into squares and enjoy!
How to Serve
- Presentation: Plate the bars neatly on a serving platter and garnish with a sprinkle of sea salt for elegance.
- Accompaniments: Serve with a scoop of vanilla ice cream or whipped cream for extra indulgence.
- Portions: Cut into smaller squares if serving at a party or larger if you’re treating yourself.
