It's 116°F in my driveway today, so I figured, why not try an experiment!

I had some industrial grade frozen cookie dough pucks left over from a closed restaurant, so I pot one piece peanut butter and one chocolate chip on some parchment on a rimmed aluminum baking sheet and left it on the dash board, then went to the beach for a few hours. They were frozen solid when I put them in.

The results? They didn't flatten as much as they would have in a 350°F oven, but they still puffed up and had a pleasant crunch. The peanut butter one was a bit drier than the chocolate chip, but I chock it up to recipe differences. The chocolate chip also let out a tiny bit of grease, but both passed muster. No browning, of course, but that's OK. You could have easily passed these off as baked in a standard oven, and I didn't have to heat the house up running the oven.

The best part however, is that the car smells fabulous now.

So with the experiment having gone so well, I've went ahead and put a second batch of a half dozen in. Hopefully they cook before I run out of sun.

The weird pucks are the frozen chunks of cookie dough. Normally, I make everything from scratch, but seeing as this was an experiment, I wasn't about to waste good ingredients on it, nor was I willing to heat up the house if the initial experiment failed.

I'm not sure if I'm going to try bread or not. It's still supposed to be horrendously hot tomorrow. Maybe a plain old white bread? I bet it'll rise like crazy!

Stay tuned.

That's hilarious. Could be any car of course but thanks for sharing it here. Stand a thermometer up for your pic and we can see what the temp is inside.
116°! Holy hothouse batman.

Inside, probably high 100F/low 200F.

It would bake even better if you put an upsidedown clear glass bowl - would reach higher temp and also retain heat better.

And they say there is no upside to climate change!

An idea would be to put a microwave meal on the dash in the morning and go retrieve it for a late lunch.

 

[shrox]

That's so Arizona.

Just stay away from frying fish on the dash.

 

[p7wang]

Some people fry eggs on their car hood.

I hate to be a party pooper but what about your poor dash? I see cracks down the road. Good fun until then I guess.

 

[p7wang]

Good point, any suggestions for a good dash cover?

living in the southwest, have always used a sunshade. with an electric car, wouldn't even consider leaving it out in the hot sun without one. even the owner's manual suggests finding shade for the car. I'll drive all around a parking lot to find a tree to park under if I can.

For cooking stuff in the sun, well have done that. Just not in the car. I've heard of people cooking a brisket in foil in their engine compartments of their ICE car.

Just imagine what that heat does to your (our) plastic interior and upholstery!

Yeah I thought about it, but didn't bother on the first round. The second batch of 6 came out fine too, but they could have maybe benefitted from a bit more heat. The smoke from the Bobcat fire started covering the sky and I lost quite a few W/m² but whatever. They're still delicious and cooked through. I put a thermometer in one cookie and got more than 160° but I have no idea what the air temperature was.

And while we're on vehicular abuse, we had a nasty overvoltage this evening, two minutes long and peaking at 271 volts. Car wasn't plugged in, anybody know what happens in situations like these during charge? I don't think it's deserving of its own thread.

Perhaps it does (deserve its own thread).

Does the stock EVSE have any sort of over-voltage protection built into it? I don't know. I recall seeing the statement below in a thread last year:

"The EVSE is essentially an extension cord with extra safety and the ability to communicate the amperage rating back to the car. So it supplies AC into the car unmodified, and the onboard charger (inside the vehicle) rectifies and steps up the voltage to charge the battery."

If that statement is true, then during a over-voltage event the onboard charger might bear the full brunt of the high voltage. Wonder if it has any protection built in?

Automotive interior max testing temp is 85C. That’s 185F.

Unless you’re tesla. They skimp on materials and testing which is why they have features like “cabin overheat protection”.

This cookie idea is awesome. Definitely made the most out of the heatwave and had a nice treat following your outing!

If it is 116 outside and you can bake cookies on the dash the probability of the dash seeing 200 degrees is very high. Plus it is full direct UV light which degrade any plastic over time.
Granted that modern UV inhibitors are much better than 40 years ago, but still.

How did the 2nd batch turn out? Where are You where it's 116 ?!

Laminated glass, like windshields, block over 95% of UV rays.

Does a normal car windshield block UV rays?

Answer (1 of 11): > I know side and rear automobile windows do not block much of the UV rays from sunlight. I have heard conflicting info about the windshield as they are constructed differently. Yes, a windshield, being a laminate, has additional layers compared to side glass. It blocks almost ...

Side window...not so much.
