Ready, Set....Turn on the Oven!
At this point, the oven's still not turned on yet. Before you turn it on, do the most time consuming tasks first. My baking plan for the day included lemon bars, brownies that became both the base for the Almond Joy Brownie Bombshells and Nutella Crunch Brownies, banana bread, Nutella Peanut Butter Oatmeal Cookies and Diamond-Edged Melt-in-Your-Mouth Butter Cookies. Out of all of those things, I already had the cookie doughs made and ready in the freezer. The banana bread batter is quick and easy to put together so instead, I did the shortbread base for the lemon bars first. While the crust baked, I mixed the lemon curd layer.
If you're making anything with nuts, those should go in first so you can toast them and they have time to cool by the time you need to incorporate then into your baked goods. If you're making sandwich cookies, those should go in next, again so they have time to cool before you sandwich them with filling. Likewise anything that needs to be frosted so they have cooling time before you frost them. This isn't so much about oven management but time management in general. If you're trying to keep a certain amount of baking hours throughout, plan your baking schedule to maximize the time you have in the kitchen while also keeping the amount of that time to a manageable level. It's a bummer if you're so busy in the kitchen that you don't get to spend time with your friends and family outside of the kitchen because you're still baking.
I baked the lemon bars off first so they would get the longest cooling time since lemon bars are messier to cut if they're warm. While the lemon bars had their second baking with the lemon curd layer, I worked on the brownie batter I wasn't done filling the mini muffin pans with the brownie batter by the time the lemon bars were done so I put a cookie sheet of nutella peanut butter oatmeal cookies in next. Cookies are great to bake in between other things since the cookie dough is ready and they can go in at a moment's notice - just plop the dough balls onto the parchment-lined cookie sheet and into the oven they go. If you have a limited amount of cookie sheets, it's also good to bake the cookies between other items so your cookie sheets have time to cool before you use them again. Never place cookie dough on hot cookie sheets - they'll melt part of your dough before the baking even begins and cause more spread than necessary.
