Preheat oven to 350 degrees and spray a donut pan with nonstick cooking spray. Melt the butter in a small saucepan over medium heat. Add the dried lavender and bring to a simmer. Remove from heat and allow to cool 5 minutes. Pour melted butter through strainer and discard the lavender.
In a large bowl, mix together the egg, melted lavender butter, yogurt and milk. Add in the dry pancake mix and stir until a batter forms. Spoon batter into donut pan, filling each 3/4 high. Bake 12-15 minutes, until the donuts begin to turn golden. Remove from donut pan and cool completely on a wire rack.
Place the dried blueberries in a blender and pulse until they become powder. Pour into a large bowl and add the other ingredients for the glaze. Whisk together until smooth, then dip each donut into the glaze.
