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!

  1. These brownies are the best brownies I have ever eaten. I made them for a friend who is gluten free, but now just make them for everyone.

  2. I for got to note that I stared with 2 sticks of butter so everything was measured out to 2 1/3 what the recipe called for. I had a little more volume so it had to cook a little longer.

  3. OMG made these for a GF co-worker and everyone LOVES them. We are serving with strawberries since they are SO rich.
    Baker’s notes:
    • I did not line the pans, I used the store-bout aluminum ones and a butter spray (smart balance butter flavor).
    • I used a dark glass saucepan very low heat and stirred the sugar into the butter for a while.
    • I used ½ semi-sweet and ½ dark chocolate for an added richness. It was Ghirardelli chocolate because the quality for melting/baking is the best. I continued to use a very low heat stirred the chocolate in the butter and sugar for a long time. I do not trust quick melts and would rather take the time to do it slow and steady for a silky finish. I can be obsessive about this but once you ruin a chocolate melt you might as well start over.
    • I slightly beat each egg before adding them so I didn’t have to break up the yolk in the batter.
    • Definitely let the mixture cool considerably before incorporating the eggs! This was not stated in the recipe (just “remove from heat”) and I actually had some egg cook slightly as I was mixing them in – NOT cool!
    • I baked at 350 (not one degree higher) for just under 30 mins. I started checking at 25 mins and they were still too lose in the middle. Once the edges started to really crisp I called it and pulled them out. I knew all that butter would burn and burn quickly!
