So yesterday I was making cakes, getting prepared for the next couple of weeks, but I didn't have enough batter to finish one cake so I sent my boyfriend to the store. . . In the mix of the rest of the day I COMPLETELY forgot make the mix I had already mixed. . . Is it bad now?!?! It got put in the fridge but wasn't covered. . .

I'ld say I don't think so, bake it and see.
