Put bake in a preheated oven to 170 degrees (brownie is ready when a toothpick, stuck in the middle of the pie, "come out" from there wet, but not wet).
Remove the brownies from the oven, allow to cool at room temperature, and then put the brownies in the freezer for 2-3 hours (this is done to make the brownies better frozen and easier to cut).
Remove the brownies from the freezer, cut into squares and.. enjoy your meal:)
In the original recipe baking time is written 25 minutes.. I usually have so much brownie and bake, but here after 25 minutes, the cake was almost liquid and only after 40 minutes, I got the desired consistency of the cake.. So, focus on your oven.. Maybe 25 minutes is enough for you.
