Why We Love These Fudgy Brownies

  • Ready in just 30 minutes, Fudgy Flourless Brownies are perfect for last-minute desserts.

Recipe Ingredients

Chocolate brownie batter in a mixer bowl.

Semisweet Chocolate – We really prefer Ghirardelli chocolate for its deep, smooth flavor, but any high-quality semisweet chocolate will work. It adds richness and depth that makes the brownies taste indulgent and intense.

Unsweetened Cocoa Powder – For a deeper, more intense chocolate flavor, go with Dutch-process cocoa powder. It gives the brownies a dark, almost bittersweet taste.

Vanilla Extract – Adds a mellow sweetness and rounds out the richness of the chocolate.

How to Make Fudgy Flourless Brownies

Step 1: Preheat the oven to 350°F (175°C). Line an 8×8 or 9×9-inch square pan with foil (prefer a metal one), then lightly spray or butter, and set aside.

Step 2: In a small saucepan set over low heat, melt the butter, then add the sugar. Once the sugar is incorporated, add the chopped chocolate, stirring until smooth. Remove from the heat and beat for 2 minutes with a hand mixer or whisk. Add the eggs, one at a time, then the vanilla extract.

Step 3: Using a mesh sieve (or a sifter), sift the cocoa powder and cornstarch into the saucepan, then add the salt. Stir together, then beat the batter vigorously for 1-2 minutes. I like to use a hand mixer for this on medium speed. Beat until the batter is smooth and shiny.

Step 4: Pour the batter into the prepared pan and bake for 22-30 minutes or until the brownies are set in the center, taking care not to over-bake. Remove from the oven and let cool in the pan for 45 minutes before removing and slicing.

Expert Tips

Check Doneness Early – Start checking for doneness at the 22-minute mark by inserting a toothpick into the center. It should come out with a few moist crumbs—not clean—for a rich, fudgy texture.

Line with Parchment Paper – For easier removal and cleaner edges, line the pan with parchment paper. Leave an overhang on the sides so you can lift the brownies out without breaking or sticking.

FAQs

Should I cool the brownies completely before cutting them?

Yes, allow the brownies to cool completely in the pan before slicing. This helps set the texture and makes cutting easier, resulting in cleaner slices.

Can I add mix-ins like nuts or chocolate chips?

Yes, you can add mix-ins such as nuts or chocolate chips to the batter. Fold them in gently after the batter is fully mixed for an extra burst of flavor and texture.

NOTES

*I like to use 2 semisweet Ghirardelli baking bars, as they are 4 oz. each.
-Fruit, nuts, chocolate chips/chunks, a sprinkle of sea salt, or a swirl of dulce de leche all make great additions to these brownies!
