Ingredients

Lemon Poppy Seed Muffins

  • 2 1/2 cups all-purpose flour 320g
  • 1 cup granulated sugar 200g
  • 2 1/2 tsp baking powder
  • 1/2 tsp baking soda
  • 1/2 tsp salt
  • 2 tbsp poppy seeds
  • 1/2 cup unsalted butter melted, 112g
  • 2 tbsp vegetable oil
  • 2 large eggs room temperature
  • 1/4 cup sour cream room temperature, 60g
  • 2 tsp vanilla extract
  • 2 tbsp lemon zest from about 2 lemons
  • 1 tbsp fresh lemon juice from about 1/2 lemon
  • 1 cup milk room temperature, 240g

Lemon Simple Syrup

  • 1/4 cup fresh lemon juice from about 2 lemons, 60g
  • 1/4 cup granulated sugar 50g
  • Lemon peel from 1 lemon

Instructions

  • In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, baking powder, baking soda, salt, and poppy seeds.
  • In a separate mixing bowl, combine the melted unsalted butter, vegetable oil, eggs, sour cream, vanilla extract, lemon zest, lemon juice, and milk.
  • Pour the wet ingredients into the dry ingredients.
  • Using a rubber spatula, gently fold the mixture until just combined. Do not overmix.
  • Cover the bowl with plastic wrap.
  • Allow the batter to rest at room temperature for 1 hour.
  • While the batter rests, prepare the lemon simple syrup.
  • Add the fresh lemon juice and granulated sugar to a small saucepan.
  • Place the saucepan over medium heat.
  • Bring the mixture to a boil.
  • Reduce the heat and simmer for 5 minutes, or until the sugar is fully dissolved.
  • While the syrup simmers, carefully remove the peel from 1 lemon using a paring knife. Avoid cutting deeply into the white pith.
  • Place the lemon peel in a heat-safe bowl.
  • Remove the lemon syrup from the heat.
  • Pour the hot syrup over the lemon peel.
  • Allow the syrup to cool at room temperature while the muffin batter continues to rest.
  • Near the end of the resting time, preheat the oven to 425°F.
  • Line a muffin tin with 11 paper liners.
  • Using a large 2 oz scoop, or approximately 1/4 cup, divide the batter among the prepared liners.
  • Fill each liner to the top and slightly above the rim.
  • Avoid stirring or deflating the batter while scooping.
  • Bake the muffins at 425°F for 8 minutes.
  • Without removing the muffins from the oven, reduce the oven temperature to 350°F.
  • Continue baking for 8 to 10 minutes, or until a toothpick inserted into the center of a muffin comes out clean with a few moist crumbs.
  • Remove the muffins from the oven.
  • While the muffins are still warm, brush the tops generously with the prepared lemon simple syrup.
  • Allow the muffins to cool in the pan for 5 minutes.
  • Transfer the muffins to a wire cooling rack.
  • Allow the muffins to cool for an additional 15 minutes.
  • Sprinkle with additional poppy seeds, if desired.
  • Serve warm or at room temperature.
