    I’ve written many times about how much I love cookies, but I would have a hard time choosing between a chewy chocolate chip cookie and a rich, fudgy brownie. But when you add chocolate chips to the brownie, the brownie wins hands down.

    Fudgy, cakey, fudgy, cakey… can’t make up your mind? If you’re looking for a brownie that’s right in between those two styles, you’ve found it. These brownies combine a fudge brownie’s ultra-moist texture with a subtle cake-like rise for the best of both worlds. If you’re looking for the best ways to cut brownies check out my How To Cut Brownies and Brownie Round Up post!

    Why You’ll Love This Recipe

    • Perfect texture: These brownies offer the best of both worlds, combining the moist texture of fudgy brownies with a cake-like rise.
    • Shiny, crackly top: Heating the butter-sugar mixture and adding chocolate chips to the batter creates that shiny, crackly top crust that I love!
    • Rich chocolate flavor: These brownies promise a deep chocolate flavor with cocoa powder and chocolate chips. The optional espresso powder further enhances that rich taste!
    • Long lasting: These brownies are delicious fresh and stored. You can keep them at room temperature for up to 6 days, making them a great make-ahead dessert.

    Recipe Ingredients

    • Butter
    • Sugar
    • Eggs
    • Cocoa — I recommend Dutch-process.
    • Baking powder
    • Espresso powder — optional
    • Vanilla
    • Flour
    • Chocolate chips

    See the recipe card below for full information on ingredients and quantities.

    How To Make King Arthur Brownies

    1. Preheat the oven to 350°F. Lightly grease a 9″ x 13″ pan. Line with parchment paper, optional.
    2. In a saucepan, melt the butter over medium heat. Stir in the sugar and cook until the mixture is hot, but not bubbling.
    3. In a large mixing bowl, whisk eggs, cocoa, salt, baking powder, espresso powder, and vanilla until smooth. Add the hot butter/sugar mixture and stir until smooth. Add the flour and stir until smooth.
    4. Let the batter cool in the bowl for 20 minutes, and then stir in the chips. Spread batter into prepared pan.
    5. Bake for about 30 minutes, until the brownie edges are set and a cake tester inserted into the center comes out with just a few moist crumbs clinging to it. Remove them from the oven and cool completely on a rack before cutting.

    Recipe FAQs

    How do I know when brownies are baked?

    You will know when the brownies are done baking because the edges are set, and when a cake tester is inserted into the center, it comes out with just a few moist crumbs clinging to it.

    What is the best way to grease a pan for brownies?

    The easiest way to prepare a brownie pan is to spray the pan with cooking spray lightly.

    Should you let the brownies rest after baking?

    I like to let the brownies cool completely in the baking dish before cutting and serving. This will result in a much cleaner cut and prettier servings.

    Is it better to bake brownies in a glass or metal pan?

    I prefer baking brownies in a glass pan. Metal pans heat up at a much slower rate and then get very hot. Stick with the glass pans for more even baking.

    Expert Tips

    • Use quality ingredients: Use high-quality Dutch-process cocoa and chocolate chips for the best flavor. The optional espresso powder can significantly deepen the chocolate taste without adding a coffee flavor.
    • Don’t overmix after adding flour: When incorporating the flour and chocolate chips, mix until just smooth. Overmixing can lead to tough, dense brownies by overdeveloping the gluten in the flour.
    • Add some flavor: Want to spice up this recipe? Serve it with some homemade Strawberry Ice Cream!
    • Reheating tip: I recommend reheating these brownies in the oven so that the top stays nice and crackly.
