I am baking another smash cake for R tonight (1 year photos on Sat morning). I was going to make the icing and ice tomorrow. The cake batter makes enough so I was going to make cupcakes and bring them to work. But will they still be fresh Monday?? I don't think that I have time to bake, let them cool and ice tonight for tomorrow. I have a cake tupperware container I can store them in all weekend.
