"Moist poppyseed muffins with a hint of lemon come alive with a tart lemon glaze. So good you can't eat just one! You can substitute yogurt for the sour cream, if desired."
1Preheat oven to 350 degrees F (175 degrees C). Line 12 muffin cups with paper muffin liners.
2Whisk flour, white sugar, lemon zest, poppy seeds, baking powder, and salt together in a bowl. Beat buttermilk, sour cream, vegetable oil, and egg together in another bowl. Pour buttermilk mixture into flour mixture and stir until batter is just combined. Pour batter into the prepared muffin cups.
3Bake in the preheated oven until a toothpick inserted into the center of a muffin comes out clean, about 20 minutes. Cool for 10 minutes.
4While muffins are cooling, whisk confectioners' sugar and lemon juice together in a bowl until glaze is smooth. Drizzle glaze over muffins.
