8. Carefully stir in the boiling water until the batter is smooth.
9. Pour the batter over the cherries in the cake pan, spreading it evenly with a spatula.
10. Bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean.
11. Once baked, let the cake cool in the pan for about 10 minutes.
