In a medium bowl, whisk flour baking powder and salt. Keep aside
In a stand mixer with a paddle attachment or with an electric mixer. Beat butter until soft and creamy, for about 2 mins on medium speed. Then add the granulated sugar, continue creaming until the batter is smooth. Now at this stage, you beat until sugar is dissolved. But if there are granules of sugar it is fine. It will dissolve completely as we add the eggs.
Then add the eggs one after the other. mixing well at each addition on low speed. Add the vanilla extract. The batter may look curdled. Nothing to worry, its the emulsion in process
Fold in the flour. mix on low speed.This helps in getting to the bottom of the bowl and makes sure that the batter is not over mixed and no flour is left off
Add milk in the last and give one final mix with the beater or the mixer on low speed. stop the mixer.
Fold in Chocolate chips.
Transfer the batter in the prepared tin. Fill to almost ¾ of the tin. Bake for 60 to 75mins. depends on your oven. Mine took about 60 mins
Remove from the oven, let it sit in the pan for 10 mins. Before transfering to the wire rack. Any longer in the pan, will make the crumbs stick on to the pan
Cool Completely. And then glaze
Make the Chocolate Glaze
In a medium sauce pan, heat butter and cocoa. Whisk while the butter is getting melted.
Remove from heat. Whisk in the icing sugar.
Add water, as required to adjust the consistency. Strain and cool the glaze a little.
Glazing the Cake
Once the cake is completely cooled, pour the glaze on the cake.
let it set for atleast one hour before cutting them into slices.
Notes
Room temperature ingredients very important here. otherwise the cake texture will not be good.
Line your pan well.
Bake at a low temperature for a long time. this helps in uniform baking and avoids over browning the crust.
Let the cake cool completely before glazing
And once glazed, let it set for atleast an hour, before cutting into slices
