Preheat oven to 356 F / 180 C and grease your loaf pan.
Mix dry ingredients: flour, cinnamon, baking powder and salt.
Pour syrup and cider to the dry ingredients and mix carefully until well combined.
Mix berries with potato starch until berries are fully coated.
Mix berries to the batter and pour the batter into the loaf pan.
Add butter evenly on top of the batter. I usually add about 5 generous table spoons. No need to spread the butter on top as it melts in the oven.
Bake in the middle rack of the oven for 50 minutes. Check with a toothpick and if not clean, keep baking for a few minutes at a time until the toothpick test comes out clean. My loaf is usually done in about 55 minutes.
Let cool in the pan for 10 minutes before removing the bread.
Enjoy warm with berry cream or just plain (it tastes yummy either way!)
