Tangy lemon pound cake with a bright citrus glaze is a refreshing, moist family dessert. This sunny, aromatic cake is perfect for afternoon tea and spring gatherings.
Preheat the oven to 350°F and lightly butter a loaf pan. Ensure oven temperature stability for even baking.
Cream the unsalted butter and sugar together on medium speed until pale and fluffy, about 4 minutes. Add lemon zest for aromatic infusion.
Add eggs one at a time, beating well after each addition to maintain emulsion; scrape down the bowl to prevent streaks.
Sift together flour, baking powder, and salt. Add to wet mixture alternately with milk and lemon juice, starting and ending with flour, mixing just until combined to avoid overworking.
Stir in vanilla extract. Pour batter into the prepared pan and smooth the top. Bake for 50–60 minutes, testing with a toothpick for doneness.
Cool cake for 15 minutes in the pan, then turn out onto a wire rack. Combine powdered sugar and lemon juice to make glaze; drizzle over cooled cake for a bright finish.
