Mix all the dry ingredients in a bowl. In a mixing bowl or in your food processor mix the margarine, milk and water until well combined. Add the dry ingredients and mix until smooth. Preheat the oven to 180 degrees, line a muffin tin with muffin papers. Chop the berries and spoon them under the batter. Fill the muffin papers with batter and top with some additional berries. Bake for about 20-25 minutes and try with a wooden stick if the muffins are ready.
