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.
Itâs difficult to resist not indulging in fresh-out-of-the-oven cupcakes right away, but if youâre making them for a party or to give to a friend, then follow these tips for how to keep cupcakes fresh: Cool cupcakes completely before covering to keep the tops from becoming sticky, about 30 minutes. Frosted or unfrosted, cover cupcakes loosely with foil, plastic wrap or waxed paper. Store cupcakes with buttercream frosting at room temperature for up to two days. Refrigerate cupcakes with cream cheese or whipped cream toppings.
