My whipped cream looked grainy when I was frosting my cake! What happened? I did color the cream was that it?

you beat it too long.

...And if you beat it loooong enough - you'll get butter.

Ask me how I know.

HTH

Gee, Jan, personal experience??

You can only imagine the many mistakes I made teaching myself to bake and make other desserts (at 9 y.o.a.).

I was about twelve at the time of the Glorified Butter, er Rice dessert I was attempting...

Experience is definitely what you get - when you don't get what you wanted.

LOL
