Heat the waffle maker to medium (or just turn it to "on" if yours doesn't have heat settings).
Melt 2 tablespoons of butter in a small bowl and set aside.
Place your hash browns in a large mixing bowl. If you're working with frozen hash browns, heat them in the microwave for 30 seconds at a time until they are thawed.
Add the eggs, coconut flour, and spices to the hash browns, and stir until combined.
Brush the waffle iron with melted butter on both sides to prevent sticking. Scoop about 1/2 cup of the hash brown mixture into the center of the iron. Close the waffle maker tight to smash down the mixture.
Cook each waffle for about 4 minutes, or until it turns golden brown on the outside.
Repeat steps 5-6 until you've made all of your waffles, then enjoy warm! Leftovers store well in the refrigerator.
