Pumpkin Parmesan Popovers

I had some leftover canned pumpkin the other day (after making my pumpkin spice cake with cinnamon cream cheese frosting) and I didn't want to waste it.  I somehow knew that I must be able to make a popover or something with the pumpkin - even though I have never made a popover in my life, and may have only ever eaten one.  I checked out a few different recipes, and eventually came up with one that I thought might work.  For a dinner party.  Yes - I am one of those people who makes things they have never made before for guests and prays that they turn out.  Yes - I am a mediocre baker who probably shouldn't risk baked goods given the number of flops I have brought to family dinners.  None of these facts are enough to deter me, so off I went, and you know what?  Even though I forgot about them for a minute and let them get just a * little * bit too brown, they were damn near perfect - just a bit crisp and browned on the outside, but soft and a bit wet in the middle.   They were delicious and four of us polished off 12 of them.  Win!

Pumpkin Parmesan Popovers
4 eggs
1 c milk (I used fat free)
1/2 c pumpkin (canned is fine)
3 tbsp butter - melted
1 c flour
1/2 - 1 tsp salt
1/8 tsp chili powder or cayenne pepper
Parmesan cheese (oh go on - you know how much you like; just keep in mind that the Parm keeps the popovers from, well, popping over, so you might want to go easy on it.  I probably used a pinch per popover.)

Preheat your oven to 375 and spray a muffin tin with cooking spray (I used butter flavored).  Whisk together the wets: eggs, milk, butter and pumpkin.  Combine the drys (flour, salt, chili powder) and whisk those into the wets.
Pour into the muffin tin; filling each no more than 2/3 full - this was just enough batter for 12 popovers for me.
Sprinkle a pinch of Parmesan on top of each.
Bake for 30 minutes or so; slit tops to allow steam to escape and bake 10 minutes more.

And yes, you can do these in advance and reheat them - I'd say a 300 degree oven for 10 minutes or so should do it!
