My grandma said my oven runs 25 degrees hot and I laughed at her, but my cookies just came out perfect
She told me this back in March and I ignored her for 4 months until my chocolate chip cookies kept burning on the bottom, so I finally bought a $7 oven thermometer and sure enough it reads 375 when I set it to 350, has anyone else had to adjust all their recipes for a hot oven?
Wait, she called it back in March and you just laughed her off? That's the part that gets me. Grandmas are like sleeper agents with this stuff, they drop the intel months ahead of time and we all act like they're just guessing. Four months of burnt cookie bottoms before you spent 7 bucks on a thermometer is a rough way to learn that lesson.
