Add the oat flour, rice flour, Mix in the baking powder, salt, and raisins, if using to a small bowl.
Add the applesauce and milk and stir until it forms a soft dough. If needed to absorb all of the flour, add a tiny dash more milk at a time until you can form a soft pliable dough. Be careful not to flatten or knead the dough. The baking powder action begins immediately forming air pockets. That's how those nooks and crannies are formed.
Transfer to the prepared bowl. Microwave on high for 2 minutes. (Based upon a 1200 watt microwave.)
