You ignore commas in the recipe
Sometimes a recipe is also a grammar test. Every cut, chop, or sifting instruction listed after an ingredient is to be done after the ingredient is measured. So, “1 cup walnuts, chopped” means whole walnuts are measured into 1-cup container and then chopped up on a cutting board. Joy the Baker reminds us that one cup of chopped walnuts is very different than one cup of walnuts, chopped. The former, “one cup of chopped walnuts,” is a much bigger portion (you can pack more chopped nuts into a one-cup container because there’s less air space between the chopped nuts than whole nuts). Here’s how to cook your way out of the 17 worst cooking mistakes.

Never open the oven door before the cake (or cookies, or pie) has started to set. In her new baking cookbook Sweetapolita, author Rosie Alyea says this typically happens at the 20-minute mark for cakes to ensure even and complete cooking. Opening the oven door releases enough hot air to change the oven temperature, which can make for an undercooked or unevenly baked cake.
