Preheat oven to 350°. In a bowl, combine the eggs, brown sugar, pumpkin, oil and vanilla. In another bowl, combine the flour, oats, baking powder, aniseed and salt; add to pumpkin mixture and stir until well blended.
Pour into a greased and floured 8x4-in. loaf pan.
Bake until a toothpick inserted in the center comes out clean, 45-50 minutes. Cool for 10 minutes before removing from pan to a wire rack to cool completely.
