Pop-Tarts Frosted Pumpkin Pie, Limited Edition, 12 Count, 3 Boxes

This one arrives with the season and then disappears again. Frosted Pumpkin Pie is a limited edition Kellogg's has brought back on and off since 2010, usually landing on shelves in late summer and gone by the new year. The listing is three boxes of twelve, thirty-six pastries in all.

The filling is where it earns the name: a pumpkin custard carrying more fall spice than most seasonal products risk, with clove sitting well forward rather than politely behind the sweetness. The shell is plain rather than flavored, and does a fair impression of pie crust, which is why this one translates into a toaster pastry better than most novelty flavors. White frosting and autumn-colored sprinkles finish the top.

They go cold from the foil, which is how most of them get eaten, or into a toaster on a low setting; heat brings the spice noticeably forward. Three boxes suits a household that treats this flavor as an annual event rather than a one-box trial.
