Prepare the necessary ingredients. Take high-quality cocoa, it should have a rich chocolate aroma and dark color.
Chop the chocolate into small pieces and put it in a deep bowl, add the butter. Stirring, melt it in a water bath until liquid. You can also do this in the microwave, but every 10 seconds you need to remove the bowl and stir to prevent the chocolate from overheating.
200 g chocolate, 115 g butter
In a separate dish, pour the sugar. Add the eggs one by one, stirring with a whisk.
200 g sugar, 3 pcs egg
Separately, mix the flour, salt, and cocoa. It is desirable to sift the mixture to avoid lumps.
70 g flour, 1 pinch salt, 30 g cocoa powder
Pour the cooled chocolate-butter mixture into the eggs and mix well.
Add the flour. Stir until smooth.
Line the baking pan with parchment paper. Pour the batter into the pan and spread it evenly. Place in a preheated oven and bake at 180 ℃ for 25-35 minutes, depending on the size of the pan. A thin crust will form on top, and the cake should still be moist inside, so it is very important not to overcook it.
Turn off the oven and let it cool. Remove from the pan, cut into individual pieces, and serve. Brownies do not need decoration, but if desired, you can sprinkle them with powdered sugar or drizzle with melted chocolate.
