One-Bowl Butter Cake (with recipe)

This is a one-bowl butter cake, recipe taken from magazine. Just dump everything together and mix, no need to sift flour too...how simple is that?  Feels a bit weird just dumping everything though..not sure how long i should mix it till too. The recipe just say mix till it looks pale in color..i can't tell any difference in color...lol!  I think i over-beat or that i use a too small pan cos the cake erupted like a vocano..lol!  But surprisingly it does taste really good though. The texture is soft and light, and the crumbs are delicate too (not rough like the earlier strawberry cake i made earlier for my daughter's birthday which if compare to this butter cake, is indeed quite rough!!...afterall, this mixing method is even simpler....).  My only complain is although it says 'butter cake', it doesn't taste very buttery as i was expecting..it had more of eggy taste to it.  Really yummy when eaten hot, the top crust is crunchy and the cake very soft and light. Everyone in my family had 2 slices including my son.
