Cream butter and sugar. Add eggs one at a time and beat until light and fluffy. Add vanilla. Sift 2 cups flour, salt and baking powder together. Add sifted ingredients to creamed ingredients and beat. Dredge berries in some flour until coated. Fold oatmeal into your batter, then fold berries gently into mixture and pour into a loaf pan that has been buttered and coated with sugar. Bake in preheated oven at 350˚F for 1 hour and 15 minutes. 

Note: If you are using frozen berries allow them to come to room temperature prior to use.
