Combine flours and next 4 ingredients (through salt) in a large bowl, stirring well with a whisk.
Combine kefir, eggs, honey, butter, and vanilla, stirring well with a whisk. Add wet mixture to flour mixture; whisk just until combined.
Spoon batter into doughnut pans, filling two thirds full. (Use a piping bag if you want to be more exact). Bake in middle of oven until doughnuts spring back when touched and are golden on bottom (about 9 minutes). Let cool in pan slightly (about 4 minutes); turn out onto a wire rack.
Top with a mixture of sugar & nutmeg or dip into berry icing.
For Berry Icing
Over the stove, cook berries with sugar and a couple tablespoons of water over medium heat until the berries are cooked down to a sauce (about 15 minutes). Strain into a bowl to get rid of any seeds then add 1 1/2 cups of powdered sugar and 1/2 tsp vanilla extract. Mix well.
