Preparation
Preheat oven to 350 degrees F and grease 1 large loaf pan or 2 smaller loaf pans.
In a medium bowl, sift together flour, baking powder, salt, and cinnamon. Place diced berries in a small bowl and toss with 2 tablespoons flour, then set aside
In a large bowl, cream together sugar, oil, and eggs, then slowly mix in dry ingredients.
Gently fold in berries until evenly combined.
Divided batter between the prepared loaf pans then spoon jam on top. Use a knife to swirl jam into the batter.
Bake for 40-50 minutes for two smaller loaves or 55-65 minutes for a larger loaf. Tent loaves with foil for the last 15-20 minutes if they begin to brown on top.
Allow loaves to cool before slicing.
