In a small bowl, whisk the soymilk and vinegar and set aside while you move on to the dry ingredients. This is your buttermilk.
In another bowl, mix well the flour, baking powder, sugar, and salt.
Pour in your buttermilk, vanilla, and oil and stir to get everything incorporated. Make sure not to overmix your batter.
Heat a non-stick pan over medium-low heat then, if using, grease the pan with butter.
Pour about 2-3 tablespoons of batter on the pan and top it with a few of the sliced cherries. This will give the pancake the clafoutis look.
Flip the pancake when you see bubbles on the surface and cook until golden.
Repeat with the rest of the batter.
To serve, layer the custard between pancakes and top the stack with the compote. Enjoy!
