Ingredients

Scale
  • 1/2 cup (113g) unsalted butter, browned
  • 3/4 cup (150g) granulated sugar
  • 2 large eggs, room temperature
  • 1 1/2 cups (190g) all-purpose flour
  • 1 1/2 teaspoons baking powder
  • 1/4 teaspoon baking soda
  • 1/4 teaspoon salt
  • Zest of 2 medium lemons
  • 2 tablespoons fresh lemon juice
  • 2 tablespoons poppy seeds
  • 1/2 cup (120ml) buttermilk

Instructions

  1. Brown the butter: Melt 1/2 cup unsalted butter in a light-colored saucepan over medium heat, stirring frequently until golden brown and nutty (about 5-7 minutes). Remove from heat and let cool for 10 minutes.
  2. Preheat oven to 350°F (175°C). Grease an 8.5 x 4.5 inch loaf pan with butter or non-stick spray and dust with flour or line with parchment paper.
  3. In a medium bowl, whisk together flour, baking powder, baking soda, salt, and poppy seeds.
  4. In a large bowl, whisk sugar and eggs until pale and fluffy (2-3 minutes). Slowly drizzle in cooled brown butter while mixing continuously.
  5. Stir in lemon zest and lemon juice, then fold in buttermilk until combined without overmixing.
  6. Gently fold dry ingredients into wet mixture until no flour streaks remain, avoiding overmixing.
  7. Pour batter into prepared loaf pan and smooth the top. Bake for 50-60 minutes or until a toothpick inserted in the center comes out clean or with a few moist crumbs. Tent with foil halfway if top browns too quickly.
  8. Cool loaf in pan for 15 minutes, then transfer to a wire rack. Serve slightly warm or at room temperature.

Notes

Use a light-colored pan to monitor butter browning. Avoid overmixing batter to keep loaf tender. Room temperature eggs improve texture. Tent with foil if top browns too fast. For gluten-free, substitute flour with 1:1 gluten-free baking mix. For dairy-free, use browned coconut oil and dairy-free milk with lemon juice.
