Once you've cooked your homemade waffles, gently tear them into triangles (or squares, depending on the shape of your waffle iron) and transfer to a cooling rack in a single layer. Allow to cool completely before placing in an airtight freezer-safe container or plastic freezer bag. When ready to eat, put frozen waffles directly into the toaster (no need thaw) and toast on medium-low until hot. (They are delicate, so keep an eye on them as they toast to prevent burning.)
