Preheat oven to 350°F (175°C).
Grease and flour two 9x5 inch loaf pans.
In a large bowl, combine flour, salt, and baking powder.
In another bowl, mix sugar, milk, oil, eggs, poppy seeds, vanilla extract, almond extract, and butter flavoring.
Combine wet and dry ingredients until just blended.
Pour batter into prepared pans.
Bake for 1 hour or until a toothpick inserted into the center comes out clean.
Let bread cool in pans for 10 minutes, then turn out onto a wire rack to cool completely.
