So I did a little research on the internet and found a good page about freezing cupcake batter. I did two of the ways they suggested with this yummy chocolate cupcake recipe.
Mix up your recipe as usual. I actually make 12 of them for last night and froze the rest. But I would also see myself in the near future making yellow cupcakes just for the purpose of freezing. I have become a big fan of freezing lately. I mean who doesn't like a simple thaw and cook meal, snack, etc? I have gotten better about putting stuff in the fridge the night before. That generally helps ;) .
Cover and seal with plastic wrap. I used the sticky cling wrap that seals better than regular. Freeze the cupcakes until solid. I just did overnight.
Now they are ready to come out of the pan and into a freezer bag. I popped the ones out of the silicone and let them freeze a little longer individually before placing them in a bag. They can go back into a silicone or a regular tin for baking. I just didn't want my silicone tied up in the freezer.
You can let them defrost in the fridge (in a cupcake tin!) or just set on the counter for 10-15 minutes while you preheat the oven. I baked the pink one above in the liner 5 minutes from the freezer and it turned out great. Maybe 1-2 minutes added to cooking time.
-The next way to freeze the batter is to just pour it straight into a freezer bag or freezer safe container. It would be wise to measure out a certain number of cupcakes into a bag, but I had already filled about 20 cupcake liners (paper and silicone) You would just defrost this in the fridge and bake as normal.
