I went straight from frozen to liner, no thawing.
My batter was a box mix that was doctored w/ an extender recipe that had sourcream (no pudding as I used one of the mixed that says on the lable they use pudding mix in their recipe - I think that might be pillsbury, not 100% sure)
as far as bake temps nad time, I suck at that.. so I picked picked 350 and started at 17 mins and check every 2 minutes, I had to check them a few times (did not note how many) but I have a funky oven so who knows what the temp was inside! I just waited till they looked done, not brown on top (I have a habit over over baking) and had a lil spring to them when touched.
