Streusel Topping:

  • 3/4 cup all-purpose flour
  • 1/2 cup granulated sugar
  • 1 teaspoon lemon zest
  • 6 tablespoons butter chilled and cut into small pieces

For the Muffins

  • 2/3 cup granulated sugar
  • 2 tablespoons lemon zest
  • 2 cups all-purpose flour
  • 2 teaspoons baking powder
  • 1/4 teaspoon baking soda
  • 1/4 teaspoon salt
  • 2 tablespoons poppy seeds
  • 3/4 cup sour cream regular or light
  • 2 large eggs
  • 1 teaspoon pure vanilla extract
  • 1/4 cup lemon juice
  • 1 stick unsalted butter melted and cooled (8 tablespoons)

Glaze Ingredients:

  • 1 1/2 cups powdered sugar
  • 2 to 3 tablespoons lemon juice you may need more or less depending on the desired consistency


  • Preheat the oven to 400 degrees Fahrenheit. Line a standard 12-cup muffin tin with paper liners or spray the muffin tin with baking spray.

To Make The Streusel:

  • In a bowl, combine the flour, sugar, lemon zest and butter. Using a fork or a pastry cutter, combine the ingredients until the mixture is crumbly and resembles coarse meal. The crumbs should be about the size of a pea. Keep the streusel in the refrigerator until ready to use.

To Make The Muffins:

  • In large bowl, combine the sugar and lemon zest together. Rub the two ingredients together with your fingertips until the sugar is fragrant and moist.
  • Whisk in the flour, baking powder, baking soda, salt and poppy seeds.
  • In a separate bowl, whisk together the sour cream, eggs, vanilla, lemon juice and melted butter until combined.
  • Add the wet ingredients over the dry ingredients and gently stir to blend. Don’t over mix.
  • Divide the batter evenly among the muffin cups. Top each muffin cup with the crumble topping (about 2 tablespoons of crumb topping each).

 Bake for 18-20 minutes, or until the toppings are lightly golden and a toothpick inserted into the center of a muffin comes out with only a few moist crumbs attached.
  • Transfer pan to a cooling rack.  Cool 5 minutes then remove the muffins from baking tin.
  • Cool completely, then glaze with icing.

To Make The Glaze:

  • Whisk together the ingredients for the glaze and drizzle over each muffin.


  • If you don't have sour cream handy, you can use plain yogurt.
  • After topping the muffins, lightly press the crumbs down into the batter so they stick to the muffins when they rise.
  • Don't overmix the batter to prevent dense muffins.
  • Cool the muffins completely before glazing the muffins.
  • Store the muffins in an air tight container at room temperature for 3-4 days. Line the bottom of the container with a sheet of paper towel to prevent the muffins from getting soggy.
  • You can freeze lemon poppy seed muffins with or without the glaze for up to 3 months. Place them in an airtight container or in a freezer safe resealable bag to prevent freezer burn.
