Preheat your oven to 350°F (175°C) and grease and flour a 9-inch round cake pan.

In a large mixing bowl, combine the flour, sugar, cocoa powder, baking soda, baking powder, and salt. Whisk them together until well blended.

In another bowl, cream the softened butter with a hand mixer or stand mixer until smooth. Add the eggs, one at a time, mixing well after each addition. Then, stir in the vanilla extract and buttermilk.

Gradually add the wet ingredients to the dry mixture, stirring until just combined. Be careful not to overmix.

Fold in the chopped cherries and semi-sweet chocolate chips gently until evenly distributed.

Pour the batter into the prepared cake pan and spread it out evenly.

Bake in the preheated oven for 30-35 minutes or until a toothpick inserted into the center comes out clean.

Allow the cake to cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.
