Instructions

  1. Preheat your oven to 375°F (190°C) and grease a muffin tin.
  2. In a mixing bowl, combine brown sugar, white sugar, all-purpose flour, cinnamon, and a pinch of salt. Cut in cold unsalted butter until crumbly. Set aside.
  3. In another bowl, whisk together all-purpose flour, baking powder, baking soda, poppy seeds, and salt until well combined.
  4. In a separate large bowl, mix sugar with lemon zest until fragrant. Stir in sour cream, sourdough discard, melted butter, lemon juice, eggs, and vanilla extract until smooth.
  5. Gradually add dry ingredients into wet ingredients and stir gently until just mixed; do not over-mix. Fold in fresh blueberries carefully to avoid breaking them.
  6. Spoon batter evenly into muffin cups and top each muffin with crumble topping generously.
  7. Place in preheated oven and bake for about 14 minutes or until muffins are golden brown.
  8. While muffins cool, mix powdered sugar with fresh lemon juice until smooth.
  9. Once muffins have cooled slightly, drizzle with lemon glaze before serving.
