how to make Sourdough Lemon Poppy Seed Pound Cake
Ingredients:
- 1¼ cups all-purpose flour (148 grams)
- 1½ teaspoons baking powder (7 grams)
- ½ teaspoon salt (3 grams)
- 1 cup salted butter (can use unsalted) (softened 226 grams)
- 1 cup granulated sugar (200 grams)
- 3 large eggs (room temperature 130 grams)
- ⅓ cup sourdough discard (100 grams)
- 3 tablespoons lemon juice (45 grams)
- 3 tablespoons lemon zest
- 1 teaspoon vanilla extract (4 grams)
- 2 tablespoons poppy seeds (17 grams)
- 1 cup powdered sugar (120 grams)
- 3½ teaspoons lemon juice (17 grams)
- 1 tablespoon heavy cream (15 grams)
Directions:
- Preheat and prepare the pan – Heat your oven to 350°F. Grease a standard 9×5-inch loaf pan and line it with parchment paper for easy release.
- Cream butter and sugar – In a large bowl, beat the softened butter and granulated sugar together for 2 to 3 minutes. The mixture should look light and fluffy.
- Add eggs and flavorings – Beat in the eggs one at a time, mixing well after each. Then, add the sourdough discard, lemon zest, lemon juice, and vanilla extract, mixing until everything is smooth.
- Mix in dry ingredients – In another bowl, whisk together the flour, baking powder, and salt. Gently mix this with the wet ingredients until there are no dry flecks of flour.
- Fold in poppy seeds – Lightly fold the poppy seeds into the batter, mixing just until they are evenly spread throughout.
- Fill the pan and bake – Pour the batter into the prepared loaf pan, smoothing the top. Bake for 55 to 60 minutes until the cake is golden and a toothpick comes out clean. If needed, cover with foil for the last 15 to 20 minutes to prevent over-browning.
- Make the glaze – In a small bowl, whisk the powdered sugar, lemon juice, and heavy cream until you have a smooth, pourable glaze.
- Cool and glaze – Let the cake cool completely in the pan on a wire rack. Once cool, drizzle the glaze over the top and let it set before slicing.
