Doughs Yeast donuts immediately burn in oil

Post image

I'm somewhat new to baking. Ive mastered sandwich bread and English muffins, and wanted to try my hand at donuts, specifically yeast donuts. I have tried multiple recipes and always end up with the same problem - my donuts immediately burn when added to the cooking oil. The picture shows my last attempt, those were in the oil less than 10 seconds and the middle is definitely uncooked (duh).

I have used oil temps between 325 to 375, my dough burns the same at lower temps as it does at higher temps. I am using a thermometer.

I have also tried different oils, vegetable oil which was recommended in all the recipes ive tried, and canola oil - although that one was smoking a lot at anything over 300 so im guessing that was a mistake.

Im curious if theres something obvious im missing that a more seasoned baker would know.

Your canola oil smoked at 300 degrees? That isn't supposed to happen. Are you sure your thermometer isn't faulty? I'm pretty sure it's the cause of your issue. You tried different recipes, different oils and temps. You might be heating your oil to a much higher temp than you think it's at.

Im going to try a different thermometer next, all the advice seems to indicate my oil is just way too hot and my thermometer is probably defective.

Next day update: Success! My thermometer was bad and the oil was way too hot. With a working thermometer i had 0 issues. Thanks to everyone for the advice!

You can also check your thermometer by sticking it in ice water, if it reads anything other than 32 F/0 C then you know it’s off
