In a saucepan start melting the butter and once it is melted set aside. In a mixing bowl sift together all-purpose flour, Sugar, Salt, Baking powder, and Cocoa powder together.
Mix the dry ingredients together to form a homogeneous mixture. Now along with the Melted butter add in the Yogurt and Vanilla essence.
Whisk everything together evenly, the mixture may look curdled a little but that is absolutely ok. Slowly fold together the wet ingredients and dry ingredients together till they are mixed evenly without any lumps.
Now add in the chocolate chips and mix everything together. Prepare a baking pan and line it with Parchment paper.
