Preheat oven to 350deg. Fahrenheit

Lightly grease an 8inch square baking pan with cooking oil. Line with baking paper; set aside.

Combine hot melted butter, oil, and powdered sugar together in a mixing bowl. Whisk about for 2min.

Now, add 1/2 cup yogurt, 1cup all-purpose flour, 1 cup unsweetened cocoa powder, salt, melted chocolate, and vanilla essence. Mix everything well.

Now pour the batter into the preheated pan. Spread smoothly. Top with some choco chips:(optional)

Bake for about 25mins.
Remove and allow to cool to room temperature before slicing into pieces. Serve by adding some chocolate syrup and chopped almonds. Enjoy
