Preheat oven to 350 and grease a 9x5 bread baking pan.
Pit and chop cherries. Set aside.
Whisk sour cream, oil, eggs, brown sugar, buttermilk and vanilla until completely smooth.
Add flour, baking powder, baking soda and salt and mix until all incorporated.
Fold in chopped cherries and make sure they are evenly incorporated throughout.
Pour batter into the prepared baking pan.
In a medium bowl, combine brown sugar, white sugar, cinnamon and flour. Mix well until all ingredients are incorporated evenly.
Pour in melted butter and carefully fold/cut it in with a large fork. You will want to be careful so you don’t over-mix. Streusel should look like large crumbs and not paste.
Spread streusel crumble over the bread batter in the pan.
Bake for 55-65 minutes. Start doing a toothpick test in the center of bread at 55 minutes.
