I'm making 12 pans of these brownies today. I will mix them up and put them in the refrigerator to be baked tomorrow. I want them to be fresh for a Wednesday luncheon. They will be gifted to the other 11 ladies in my monthly lunch group, and the 12th for DH's class.
I need your expert opinions on this. Can I mix up the frosting today and put that in the refrigerator also until tomorrow, or should I wait and mix it up tomorrow? I'd like all the mixing to be done today so I'm just assembling tomorrow, but I don't want to end up with a glob of unspreadable frosting. (I know I'll have to melt the choco drizzle tomorrow.)
