Grease a 12-hole doughnut pan and preheat oven to 180°C (350°F).
To make the doughnuts, combine all dry ingredients in a bowl and mix well.
Add liquid ingredients and stir until most lumps are gone.
Pour into the prepared pan and bake for 25 minutes or until an inserted toothpick comes out clean.
Let cool for 5 minutes, remove from the pan and let completely before applying the glaze.
For the glaze, place berries in a small pot and cover with a lid.
Cook for about 5 minutes or until the raspberries have broken down.
Drain the berries and reserve the juice.
Place the powdered sugar in a small bowl.
Add 2-3 tablespoons of berry juice. Start with 2 tablespoons and stir to see if you've reached the desired consistency (silky and pourable, but not too thin) and add more liquid if necessary.
Brush the doughnuts with the glaze, coat with sprinkles and let dry completely.
