Who doesn’t love some perfectly baked brownie? A shiny top with a super fudgy, gooey center, rich in chocolate flavor, it is like chocolate utopia. Through the bombardment of tons of Reddit threads, baking forums like Quora, and the best recipes from sites such as Allrecipes and Serious Eats (and some NYT picks), the agreement is noticeable: the top brownies are made with high-fat ratios, quality cocoa or melted chocolate, and a few key techniques to perfection that texture. This recipe combines the best tricks to create seriously decadent results. Let’s start baking!
Start with the Right Ingredients for Maximum Richness

The use of true butter, the best quality cocoa powder without sugar, dark chocolate if melting some in, room temperature eggs, and a sugar mix of white and brown will give you the richest cake. Forum bakers say that adding a little espresso powder or instant coffee to chocolate will not only not be tasted as coffee but will also strengthen the chocolate taste.
Melt the Butter and Bloom the Cocoa

Melt your butter and then stir the hot cocoa powder into the butter. This process of “blooming” the cocoa is what brings out the chocolate intensity and it is said that the pros on Reddit often claim that this single step differentiates good brownies from great ones. Beat the mixture very hard until it becomes smooth and shiny.
Whisk Eggs and Sugar Like Crazy for That Shiny Crackly Top

Combine the eggs, sugar, and vanilla, then use a whisk to mix until a thick ribbon forms. Not only does this process bring air in but it also helps the formation of the cracking crust that everyone is raving about.
Fold in Dry Ingredients Gently

Flour, salt, and baking powder should be sifted or whisked together. The dry mixture, just as combined, should be folded into the wet mixture. Overmixing results in the cookies having a cake-like texture; while under-mixing retains gooey centers.
Underbake for Ultimate Fudginess

Dust them to tempt the mouth at 350°F (175°C) in a pan lined with parchment paper of size 8×8 or 9×9 for 25 to 30 min. But take them out when the sides are firm, and the middle is still a bit shiny or a toothpick has crumbs with moisture. Most bakers say overbaking is the #1 killer.
Cool Completely And Then Chill for Extra Fudge Factor

After cooling for 1 hour in the pan, if you desire slices of ultra-fudgy texture, then put it in the refrigerator for a short time. It is a disaster to cut warm brownies; however, patience gives clean edges and good texture. For that sweet-salty contrast which is so popular, sprinkle flaky sea salt on top right after baking.
Pro Tips from the Baking Community

Use parchment paper with overhangs for brownies to lift out of the mould easily. For extra indulgence, swirl in peanut butter or caramel before baking. Store in an airtight container. They actually improve on day two or three as the flavors meld.
