Perfect, rich, fudgey brownies that, thanks to the addition of condensed milk, not only have a chocolate flavor but also a luxuriously smooth texture.You can top them with a scoop of vanilla ice cream, caramel sauce or a sprinkle of sea salt to enhance the contrast of sweet and salty.
Preheat the oven to 180 °C (350 °F). In a saucepan over low heat, melt the butter. Sift together the flour and cocoa, add the salt and sugar. Stir with a whisk.
Add the eggs, condensed milk and melted butter to the dry ingredients. Mix the batter until smooth and uniform.
Pour the batter into the mold, sprinkle chopped chocolate on top and stir it into the batter. Bake in preheated oven for 20-25 minutes depending on desired texture. Cool and cut into squares to serve.
