Step-by-step instructions

1. Preheat your oven to 350°F (177°C) and line a 9×13-inch pan with parchment paper, allowing some overhang for easy removal later.
2. In a medium saucepan, melt 1/2 cup of butter along with the chopped chocolate bars over medium heat, stirring constantly for about 5 minutes. Remove from the heat and let it cool for approximately 15 minutes.
3. Whisk in 1 cup of granulated sugar, then add the eggs one by one, mixing thoroughly between each addition. Stir in the vanilla extract, followed by the flour and salt until just combined.
4. In a large bowl, cream together the softened butter and brown sugar until smooth. Add the remaining 1/4 cup of granulated sugar, the egg, and the vanilla extract; mix well.
5. Gradually incorporate the flour, cornstarch, baking soda, and salt into the cookie mix, stirring until combined, then fold in the chocolate chips.
6. Spread the cookie dough evenly across the prepared pan, pressing in the peanut butter cups for an added surprise. Pour the brownie batter over the cookie layer, smoothing the top for an even finish.
7. Bake in the preheated oven for 40-45 minutes or until the center is set but slightly soft. If the edges seem to cook too quickly, tent with foil to protect them.
8. Let the bars cool completely before lifting them out using the parchment overhang. Cut into squares, and enjoy! These bars can be stored at room temperature for up to a week—if they last that long!

Best ways to enjoy it

The fun doesn’t stop at just eating these bars straight from the pan! Try serving them warm with a scoop of vanilla ice cream on top for an extraordinary dessert experience. Add a drizzle of caramel sauce or chocolate sauce for an extra layer of indulgence. They also pair beautifully with a glass of cold milk or a rich coffee.

How to store

To keep your delicious Chocolate Chip Cookie Brownie Bars fresh, store them in an airtight container at room temperature. They’ll last up to a week—though good luck keeping them around that long! If you want to freeze some for later, cut them into squares and freeze them in a single layer before transferring to a freezer-friendly bag. They can be reheated gently in the microwave for that fresh-baked feel whenever you desire.

Helpful cooking tips

1. Make sure your ingredients are at room temperature for better mixing.
2. Don’t overmix the batter once you add the flour—this helps maintain the chewy texture of both layers.
3. For a fun variation, try using different types of chocolate bars or nut butters in the brownie layer.
