Hi Claire,
I don't know how to grind any flours, except for almond flour. I take a handful of raw almonds and toss them in a coffee grinder, and grind them until they're a fine meal. Keep refrigerated.
I do have some muffin recipes that use only almond flour. Most do not have dairy, either. I have never tried them, so I don't know if they're any good or not. They're from a cookbook, so I don't think I can post them here, but I can email or pm them to you (and anyone else). Just let me know.
