Grab a glass of milk and enjoy some decadently rich chocolate cookie bars with gooey chocolate chips inside. These bars are easy to make using a bowl and spoon and can be in the oven in less than 15 minutes.

Chocolate lovers will celebrate when they take a bite of one of these double chocolate cookie bars. They have a robust chocolate flavor profile.
Not only are the bars made using cocoa powder and melted chocolate but they are loaded with chocolate chips too.

You can enjoy the cookies while they are still warm and they will have a fudgy brownie-like texture with gooey melted chocolate chips.
If you allow the cookies to cool, they will firm up and have a more cookie-like texture.
They are amazing either way and I know you will love how easy they are to make.

Let's make double chocolate cookie bars.
You'll need:
- microwave-safe mixing bowl
- wooden spoon or silicone spatula
- 8-inch square baking pan
- optional: non-stick tin foil or parchment paper
What chocolate to use to make these cookie bars?
The primary flavor component in these cookies is chocolate so be sure to use semi-sweet chocolate that you enjoy eating straight out of the package.
You can use chocolate bars or chocolate chips in this cookie bar recipe. If you use bars, be sure to finely chop the chocolate that will be melted and roughly chop the chocolate that will be mixed into the chocolate cookie dough.
This recipe also calls for cocoa powder to be mixed into the dough. It's best to use either Dutch Processed Cocoa or my preference, Hershey's Special Dark Cocoa which is a blend of natural and Dutch cocoa. Both of these types of cocoa will add a richer more chocolatey flavor to your cookie bars than natural cocoa powder.

Decadently rich chocolate cookie bars loaded with chocolate chips are best served with a tall glass of cold milk. They are easy to make using a bowl and spoon. No mixer is needed!
Ingredients
- 170 grams or (6 ounces or 1 cup) semi-sweet chocolate (chips or finely chopped bars)
- 113 grams (or ½ cup or 1 stick) unsalted butter
- 22 grams (or 3 tablespoons) Dutch Processed or special dark cocoa powder
- 141 grams (or ⅔ cup packed) light brown sugar
- 38 grams (or 3 tablespoons) granulated sugar
- 1 large egg
- 2 teaspoons vanilla extract
- 128 grams (or 1 cup) all-purpose flour
- 1 teaspoon baking powder
- ¼ teaspoon table salt
- 170 grams (6 ounces or 1 cup) chocolate chips
Instructions
- Preheat your oven to 350 degrees Fahrenheit.
- Line an 8-inch square baking pan with non-stick tin foil or parchment paper.
- Combine the 6 ounces of semi-sweet chocolate with the butter in a microwave-safe mixing bowl.
- Heat on high power for 30-second increments, stirring after each until melted.
- Alternatively, melt the chocolate and butter in a small saucepan set over low heat, then pour it into a mixing bowl.
- Stir the cocoa powder into the melted chocolate. This will intensify the flavor of the cocoa powder.
- Add the brown sugar and granulated sugar and stir until well blended.
- Mix in the egg and vanilla.
- Stir the flour, baking powder, and salt together then mix it into the chocolate cookie dough.
- Fold in the chocolate chips.
- Spread the cookie dough into the 8-inch square pan.
- Bake for 20 minutes, then rotate the pan.
- Continue to bake for 4-8 minutes until the edges firm up but the center still jiggles slightly but does not look wet.
- Remove and let cool in the pan for at least 30 minutes.
- Cut the cookie into 16 bars.
Notes
Why do you use weights in the ingredients list?
When baking, it is always best to weigh your ingredients, particularly flour. If you have a scale, weigh your ingredients. You'll get the most accurate measurements using grams.
I do include measurements in grams, ounces, cups, tablespoons, or teaspoons to make it easier for you.
How to measure flour without a scale?
If you do not have a scale, spoon the flour into a dry measuring cup then scrape across the top of the cup with a spatula or knife.
How to tell when double chocolate cookie bars are done?
The edges of the cookie will bake more quickly than the center of the cookie. If you prefer more fudge-like cookie bars, then bake just until the edges look set and the center still jiggles for about 24 minutes. For firmer cookie bars, bake until the center no longer jiggles for about 28 minutes.
Can I eat these cookie bars warm?
If you really want to enjoy a cookie bar with a gooey center, eat them while they are still warm. The chocolate chips will still be melted and the cookies will be soft and chewy. Once the cookie bars have cooled, the chocolate chips will firm up as will the cookies. You can warm them back up in the microwave for 5-10 seconds if you enjoy them warm.
For a truly amazing dessert, top a cookie bar with a scoop of ice cream.
How to store chocolate cookie bars?
Store in an airtight container at room temperature for up to 4 days.
OR, wrap well in plastic wrap and place in a zip-top bag, then freeze for up to 3 months.
