Preheat the oven to 375 degrees. Line a muffin pan with cupcake liners.
In a large bowl, whisk together the flour, baking powder, salt, and powdered lemon peel (if using). Set aside.
In a medium bowl, beat together the sugar, milk, eggs, butter, poppy seeds, and lemon zest until well-combined. Pour the wet ingredients over the dry ingredients and mix gently until just combined.
Scoop into muffin cups. Makes approximately 18 muffins.
Bake for 19-22 minutes or until knife inserted into the center of a muffin comes out clean.
Glaze: Whisk together the powdered sugar, lemon peel, and milk. Add more or less milk to reach desired consistently. Drizzle onto the tops of the muffins.
