Preheat oven to 325 degrees F. Lightly grease an 8-by- 4-inch loaf pan. Whisk together flour, baking powder, and salt in a bowl.
Beat butter and sugar on medium speed with an electric mixer until light and fluffy, 1 to 2 minutes.
Add eggs, one at a time, beating to incorporate after each addition. Beat in vanilla and almond extracts.
Reduce speed to low and beat in flour mixture and milk alternately, starting and ending with flour mixture, just until flour is incorporated.
Fold in poppy seeds. Pour batter into prepared pan.
Bake until a toothpick inserted in the center comes out clean, 45 to 55 minutes.
Cool in pan on a wire rack for 15 minutes, then remove to rack to cool completely.
