Preheat the oven to 350°F (175°C) and grease a round cake pan.

Wash and pit the cherries; slice them in half if desired.

In a medium bowl, whisk together flour, baking powder, and a pinch of salt.

In a large bowl, beat sugar and eggs until light and fluffy. Add sour cream and vanilla; mix well.

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

Pour batter into the prepared pan and bake for 35-40 minutes or until a toothpick comes out clean. Cool slightly before serving.
