Grease a 6-cup doughnut pan or 12-cup muffin pan with melted butter.In a mixing bowl, stir together the melted butter, eggs, vanilla, honey, strawberry jam, and milk until combined. Add the flour, strawberry powder, baking powder, baking soda, and salt, mix until just combined.Divide the batter evenly among the prepared pan, filling 1/2-2/3 of the way full. Bake 10-12 minutes, until just set. Remove and let cool 5 minutes, then run a knife around the edges to release and invert the pan.To make the icing, mix all ingredients in a bowl with 3-4 tablespoons strawberry powder. Add additional milk to thin, as needed. Dip or drizzle the doughnuts into the glaze. Let set for 5 minutes. Snack, and enjoy!
