Instructions

Prevent your screen from going dark as you follow along.

  1. Preheat the oven to 350°F. Lightly grease a 9" x 13" pan.

  2. Crack the 4 eggs into a bowl, and beat them at medium speed with the cocoa, salt, baking powder, and vanilla for about 1 minute, or until smooth. You can do this while you're melting your butter (next step).

  3. In a medium-sized microwave-safe bowl, or in a saucepan set over low heat, melt the butter, then add the sugar and stir to combine. Or simply combine the butter and sugar and heat, stirring, until the butter is melted. Continue to heat (or microwave) briefly, just until the mixture is hot (about 110°F to 120°F), but not bubbling; it'll become shiny looking as you stir it. Heating the mixture to this point will dissolve more of the sugar, which will help produce a shiny top crust on your brownies.

  4. Add the hot butter/sugar mixture to the egg/cocoa mixture, stirring until smooth.

  5. Add the flour and chips, stirring until smooth. Again, adding the chips helps produce a shiny top crust.

  6. Spoon the batter into a lightly greased 9" x 13" pan.

  7. Bake the brownies for 28 to 32 minutes, until a toothpick inserted into the center comes out clean, or with just a few moist crumbs clinging to it. The brownies should feel set on the edges, and the center should look very moist, but not uncooked. Remove them from the oven and cool on a rack before cutting and serving.

Tips from our Bakers

  • Be aware: Some of your baking ingredients can be a hidden source of gluten. Learn more at our blog post: For gluten-free baking, think beyond just flour. For additional information on King Arthur-produced products, read the complete details of our allergen program, including our contact-prevention practices.

  • This recipe is written using Dutch-process cocoa. If you use natural cocoa, your results may be different; the brownies may taste slightly acidic, and might be denser.

  • When testing to see if brownies are done, take a toothpick or the tip of a sharp knife and carefully poke it into the center of the pan, digging around just enough to see the interior. You should see moist crumbs, but no uncooked batter. Yes, you'll be left with a small divot in the center of your brownies; just cut around it when you're cutting the brownies into squares.

  • Big Batch Brownies: To make a larger batch use the following measurements:
    6 large eggs
    2 cups (170g) Dutch-process cocoa
    1 1/2 teaspoons salt
    1 1/2 teaspoons baking powder
    1 1/2 tablespoons (21g) vanilla
    1 1/2 cups (339g) butter
    3 cups (594g) sugar
    2 1/4 cups (270g) King Arthur Gluten-Free Measure for Measure Flour
    3 cups (510g) chocolate chips
    Spread the batter into a lightly greased or parchment-lined half sheet pan (about 13" x 18" outside dimensions). Bake in a preheated 350°F oven for 30 to 35 minutes or until the brownies test done as described above.
