I bake and decorate alot of sheet cakes and frosting pride is what my family prefers. I think cream cheese buttercream is the way to go myself (yum!) Frosting Pride can be overwhipped and it looks chunky & is hard to pipe - I have done that myself
Once you start whipping it in the mixer as soon as you have some volume: watch it close, stop the mixer and test it with a spatula. I will whip it in 30 second intervals just to be sure - I also under whip it when its time for piping. To get it smooth I use a large metal scraper. Gel colors work awesome but you will always get a lighter color.
Hope this helps!
OOOh - seeing everyone talk about tres leches - do you have a go-to recipe you could share with me? I've never tried it and it sounds delish
