Pop tarts are rectangular, pre-baked toaster pastries which are made by Kelloggs.
They have sugary filling which is sealed inside two layers of rectangular, thin pastry crust.
Most of the varieties that you can get are frosted as well.
They are designed to be warmed inside a toaster or microwave oven.
Pop-Tarts are produced in dozens of flavors, plus various one-time, seasonal, and “limited edition” flavors.

So can rabbits eat pop tarts at all?
Unfortunately, rabbits are unable to eat any kind of cooked food as they are herbivores.
They are fine to have a nibble of them but nothing more than that.
