i dont normally heat mine either but i toasted 'em when i did.... but whoa 4 seconds?! i think i'll start...
Toaster but only cook them for thirty seconds because they will get nice and soft and uber delicious.
I haven't eaten them in years and years, but I liked the toaster method. I'm not even sure we had a microwave back then......
I either microwave them or freeze them, but they're not my favorite. I like the cream cheese toaster strudels or whatever they're called...they're the ones that come from the freezer...and yeah I pop those into the microwave too. lol
if it's a fruit flavoured one, I toast it in the toaster oven. The chocolate ones I don't toast at all.
I do not believe I have had a poptart in this millenium, but if I were to have one, they would surely be toasted.
