Please help! White dots on surface of butter cake?
ChefTalk.com Top Picks
I'm just a home baker but was curious myself. I googled "white spots on cake tops" and found the following. However, it doesn't address the issue of the commercial oven. Hope one of the pros here can help!
Sugary tops or white spots on cakes:
- Too much sugar
- Not enough liquid (to dissolve the sugar)
- Sugar too coarse (to be fully dissolved)
- Cakes standing too long before going in the oven. This allows moisture to escape from the top of the cake, and leaves sugar residue in the batter.

I am noticing that you are mixing cupcakes with the two-bowl (or muffin method) of mixing. I would try the creaming method and see where that takes you. Also, if the commercial oven is gas it then adds more humidity to the game so you might find that by creaming your ingredients will give you a more consistent product.
My first thought was to say be sure to sift your drys together as sometimes the leavenings form tiny crumbs/balls if exposed to moisture ie humidity.
Same with the sugar.
But what it all boils down to the taste, right?
Can you make a dozen or so...ice them then send them out for a taste test.
We are our own worst critics but if the problem is solved by a bit of smoke and mirrors IMO all is well.
As @Fablesable mentioned butter cakes start with the butter and sugar being creamed to pale and fluffy.
All I can add is to start off with the butter frozen and cut into chunks.
The heat of the machine will soften the butter and you are more likely to get a fluffy texture.
Room temp fat sort of just melts trapping the sugar and not much incorporation( dissolved sugar) takes place before it is deemed ready for the eggs .
Sorry that's all I have but maybe it will ring some bells lol.
This might have already been said. Try your formula with a better sugar or flour. During the baking process most of the impurities rise to the top. The skin is sweeter and some people really like this. For me, I can do without the roach parts and such.
