Brownies with sour cream

Melt chocolate with butter. Add sugar, flour, baking soda and lemon juice. When the mixture has cooled slightly, add eggs. Bake for 30 minutes at 180 C. While brownies baked, whisk the sour cream with sugar. It is better to do it with a stationary mixer, because it will take a lot of time until it gets thick. When the brownies are cooled down, spread cream on the top. Bon Appetite!
