Once frozen, transfer the waffles to a large freezer bag. Seal and freeze.
Preheat the oven to 450°. Place the waffles in a single layer on a baking sheet and cook them for around five minutes, flipping the waffles halfway through the cook time.
Set the toaster to the medium/high setting and place the waffles in the toaster. After the first toasting, push the lever down again to brown and crisp them before serving.
Set the oven to the light or low setting and place the waffles inside. Cook for two to three minutes, until the waffles are golden brown.
