Ingredients Needed

  • Unsalted butter: Make sure that it’s melted. 
  • Granulated sugar: Perfect for a bit of sweetness. 
  • Light brown sugar: When measuring, pack it down tightly before adding. Dark brown sugar may be substituted.
  • Eggs: Used as the binding agent for the dry ingredients. 
  • Vanilla extract: I love using pure vanilla extract. 
  • Unsweetened cocoa powder: This recipe has been tested with regular cocoa, but you can use Hershey’s Special Dark as well.
  • Baking soda: Just a tad bit is needed. 
  • Salt: Just a pinch. 
  • All-purpose flour: Used as the main batter ingredient for the blondies. 
  • Semi-Sweet Chocolate chips: You can also use milk chocolate chips or white chocolate chips.

  • Preheat the oven: Preheat the oven to 350 degrees. Add foil or parchment paper to a 9X13 baking dish and spray with cooking spray. 
  • Mix: Add the melted butter into a bowl and mix in the granulated sugar and brown sugar on low speed. Once combined, add the egg and vanilla and mix on medium speed. 
  • Add dry ingredients: Mix in the cocoa, baking soda, and salt. Once that is combined, slowly add the flour and mix just until the batter is smooth. 
  • Add the chocolate chips: Slowly add the chocolate chips and then press the dough into the pan. 
  • Bake: Put the pan in the oven and bake for 19-24 minutes. Let the bars cool completely before cutting. 

Variations 

  • I think that adding nuts like pecans or walnuts adds a crunch to this chocolate chip bar recipe that can’t be topped. 
  • Dark chocolate chip cookie bars could totally be a thing as well if you use dark chocolate chips! Sprinkle some mini chocolate chips right on top! 
  • Plus, the more chocolate that you add, the more possibilities that you have. You can make a double chocolate cookie bar recipe, triple chocolate cookie bars, or even a chocolate chip bar smothered in frosting! 
  • Adding chocolate frosting on top or even homemade ice cream is the best! 
  • These would also be amazing with some flaky sea salt sprinkled on top.

Expert Tips

  • Make sure that you don’t overmix the batter for these double chocolate chip cookie bars. Just mix until combined and bake. 
  • This cookie chocolate bar will firm up as it cools, so give it some time before cutting into it. 
  • Store these in an airtight container for up to 3 days or freeze them for up to 3 months.

FAQs

How to know when cookie bars are done baking?

If you’re worried that these chocolate chocolate chip cookie bars aren’t done, just look at the top and the edges. The top should lose the glossy sheen and be lightly golden, and the edges will start to pull away from the sides. 

Do you have to chill cookie bar dough? 

Nope, not at all! Recipes with chocolate bars that don’t have to be chilled are the best. It’s such a huge time saver.

  1. Is it 3 cups of chocolate chips or 310 grams? I ask, because regular sized chips are at least 170 grams per cup.

  3. Made this today and it was amazing! Not sweet but oh so chocolaty!!! The only thing I will do differently is try baking it in a 15×17 pan. I thought they were a little thick for a pan cookie using a 13×9.

  4. i made this recipe with a few alterations. i used white chocolate chips, added 1 teaspoon of instant espresso powder, and added about 1/4 cup of Chocolate Ovaltine. the Ovaltine added a little malt flavor and the white chocolate chips contrasted the rich chocolate. couldn’t taste the espresso powder but it amps up the flavor of chocolate.
