I tried making gluten-free hot cross buns and they raised well but didn't quite have the texture I was hoping for. They were edible, but not quite worthy of posting for Easter this year.
If you are interested in making hot cross buns, try using your favorite yeast roll recipe and add a little extra sugar and fat, some dried fruit (raisins, currents, dates) and your favorite spices (we like cinnamon and cardamom with a little nutmeg and allspice). I used muffin tins since that size works nice for us. Don't forget to brush the tops with a beaten egg before baking for that shiny appearance. And, of course, finish off with a cross of white icing (powdered sugar, water and vanilla, if desired).
