The answer to this question is a bit complicated. There are ways to cook a toaster strudel in the microwave, but it might not come out hot enough, or it might come out too hot because the microwave does not heat evenly.
Some people, myself included, only use the microwave to thaw a frozen toaster strudel, then pop it into the toaster to finish cooking, and it turns out perfect every time.
If You Choose to Make a Toaster Strudel in The Microwave:
Unless you have a microwave toaster combo, the microwave is not the best way to prepare a toaster strudel, but it is still possible.
It is fairly simple to prepare a toaster strudel in the microwave; here are the steps:
Take the strudels out of the freezer and place one, or two, on a microwave-safe plate.
Place the strudel in the microwave and set the microwave for 30 seconds.
Stop the timer half-way through (15 seconds) and flip the strudel over.
Careful, it may be hot!
Replace the strudel in the microwave and allow it to finish cooking. Check the strudel to ensure it is warm enough.
If it is not, you can continue microwaving it for 5-10 seconds at a time until it is to the desired temperature.
Put the icing on the strudel and enjoy it! You can also make other tasty treats by warming Nutella or even making S'mores in the microwave.
Other Ways to Make a Toaster Strudel:
There are other alternatives to make a toaster strudel, and one of those ways is in its name. Yes, you guessed it, it's the toaster!
Most people make their toaster strudels in the toaster because there is not much to it, you just pop it into the toaster, and within minutes you have a delicious breakfast or snack.
Another way to make a toaster strudel is to bake it in the oven.
Baking toaster strudels takes longer than microwaving or toasting, and it can also make a mess if you do not take the right precautions.
You would need to place the toaster strudel on a foil-lined baking sheet to catch any of the filling that might escape the pastry while cooking, and you would also need to flip the pastry half-way through cooking to ensure it cooks evenly on both sides.
Whatever method you choose to make your toaster strudels is up to you. They will be delicious either way!
