Kopitiam Milk Buns / Plain Milk Buns (Overnight Sponge Dough Method)

Kopitiam Milk Buns is the plain milk buns that always selling at coffee shop when we were young. It doesn't has any distinctive taste, so the usual ways of eating it is by dipping the bun into the coffee, milo, soft boil egg, or go with kaya and butter. This bun was very popular among bloggers two years back. I always not able to keep up with the current popular bakes.

I tried with two recipes this round, one with overnight sponge dough and the other one with straight dough method. Both gave me soft bread on the day of bake, however, the bread was not soft to touch on the second day and I have to heat them up in the microwave for 20 seconds to get the soft bread. I'm not sure could it be the butter used was way too little for the straight dough and was it the overnight sponge dough I used way too dry? 

I referred the recipe from My Little Favourite DIY (overnight Sponge Dough Method). This recipe yield 9 buns.
