In a large bowl, combine almond paste and butter; beat until well blended. Gradually add sugar, beating until light and fluffy. Add eggs, one at a time, beating well after each addition. In a small bowl, gently toss cherries and 1 tablespoon flour. Set aside.
Combine the baking powder, salt, remaining flour; add to the creamed mixture alternately with milk, beating well after each addition.
Spoon a sixth of the batter into each of two greased and floured 8-in. x 4-in. loaf pans; sprinkle layers with half of the fruit. Cover with another layer of batter and sprinkle with remaining fruit. Top with remaining batter; smooth with spatula.
Bake at 350° for 1-1/4 hours or until a toothpick inserted near the center comes out clean. Cool for 10 minutes before removing from pans to wire racks to cool. Yield: 2 loaves (16 slices each).
