In a large mixing bowl, whisk together the whole wheat pastry flour, baking powder, sugar, salt, and cinnamon.
In another bowl, combine the beaten eggs, milk, vanilla extract, and the contents of half a vanilla bean. Stir well to combine.
Pour the wet mixture into the dry ingredients. Gently fold everything together until just combined.
Gently fold in the frozen cherries into the pancake batter.
Preheat your non-stick skillet or griddle over medium heat. Lightly grease with a bit of oil or butter.
Pour about 1/4 cup of batter onto the skillet for each pancake. Cook until bubbles form on the surface, about 2-3 minutes. Flip and cook until golden brown.
In a small saucepan, combine the frozen cherries, powdered sugar, heavy cream, milk, and the contents of half a vanilla bean. Cook over medium heat until thickened, about 5-7 minutes.
Stack the pancakes on plates, drizzle with the warm cherry glaze, and enjoy!
