Preheat oven to 350 degrees. Line a 9 x 5 loaf pan with parchment paper and set aside.
In a large bowl, beat butter and sugar with an electric mixer until creamy.
Add eggs, one at a time, beating after each addition until fully combined.
Use a spatula to fold in vanilla and sour cream. Scrape down the sides of the bowl as needed.
In a separate bowl, whisk together flour, baking powder, baking soda and salt.
Add cut cherries and 1/3 cup of chocolate chips to flour mixture, stirring gently until completely coated.
Carefully fold dry ingredients into wet until batter is just barely combined. Note: batter will be thick. Avoid overmixing.
Spoon batter into prepared loaf pan. Level with a spatula then top with remaining chocolate chips.
Bake for approximately 50 minutes or until a tester inserted into the center of the loaf comes out with a few moist crumbs. For best results, do not overbake.
Cool bread in pan for 15 minutes before removing to a wire rack to cool completely.
Garnish loaf with fresh Bing cherries then slice and serve.
Cover bread with plastic wrap and store at room temperature for up to 3 days or in the refrigerator up to 7 days.
