As a rule, a CTE will NEVER improve performance. A CTE is essentially a disposable view. There are no additional statistics stored, no indexes, etc. It functions as a shorthand for a subquery. In my opinion they can be EASILY overused (I see a lot of overuse in code in my job).
Check the cupcakes at the minimum baking time. If the recommended baking time is 18-22 minutes, check them at 17 or 18 minutes (just a quick peek, make sure not to let too much heat out of the oven). If the tops are rounded and no long appear wet, they may be done.
Jumbo. 3 1/2 x 1 3/4 inches. If you have only one pan and a recipe calls for more cupcakes than your pan will make, just cover and refrigerate the rest of the batter while baking the first batch. Cool the pan about 15 minutes, then bake the rest of the batter, adding 1 to 2 minutes to the bake time.An easy way to fill baking cups is to use an ice cream scoop. Use one that measures out 1/3 cup batter when filling regular-size cups. Use one that measures out 2 tablespoons batter when filling mini cups.
