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

In a large bowl, whisk together flour, baking powder, and salt; set aside.

In another bowl, beat the butter and sugar until light and fluffy. Add eggs one at a time, then mix in sour cream and vanilla.

Gradually combine dry ingredients with wet mixture until just blended. Gently fold in cherries.

Pour batter into the prepared pan and bake for 30-35 minutes or until a toothpick comes out clean.

Allow the cake to cool before serving.
