This lemon poppy seed poundcake is summery and quick to make, and perfect for a picnic. One tip: cut up the poundcake before the picnic but leave it in the baking pan. It makes it easier to transport, and the pan protects it, too. Then serve it on its own, with ripe berries, and let the ants enjoy the crumbs.
Heat oven to 350 degrees. Butter and flour an 8-inch loaf pan.
In a bowl, combine lemon zest and sugar and rub with your fingers until it looks like wet sand. Whisk in buttermilk, 3 tablespoons lemon juice and eggs. In a separate bowl, whisk together flour, baking powder, baking soda and salt. Whisk dry ingredients into the batter, then whisk in oil and poppy seeds.
Pour batter into prepared pan. Bake until a toothpick inserted in the center emerges clean, about 1 hour. Let cool in pan until warm to the touch, then turn out onto a baking rack set over a rimmed baking sheet. Turn cake right side up.
Whisk together remaining 4 teaspoons lemon juice and the confectioners’ sugar. Use a pastry brush to spread glaze evenly over top and sides of cake. Cool completely before slicing.
