In a large bowl, whisk together flour, baking powder, and 1/4 cup of brown sugar until well mixed.
Next whisk in Safest Choice eggs, buttermilk (or coconut milk), melted butter, vanilla extract and cinnamon until batter just comes together. Leave the lumps there. No need for a smooth batter.
Heat a griddle or non stick skillet over medium heat and melt extra butter.
Once hot, add one pineapple ring to center of griddle or skillet. Sprinkle the top of pineapple with a little of remaining brown sugar and turn over after browned a bit.
Optional: Add a cherry to the center of the pineapple ring.
Pour about ¼ of a cup of batter over the pineapple allowing it to go outside of the ring. Cook until bubbles form and the bottom is more sturdy, golden brown and crisp.
Carefully flip entire pancake over, including pineapple and cherry (use a large spatula since this process can be a bit more flimsy with the weight of the pineapple). Cook until golden brown and crisp on the other side.
Remove the pancake and place in a warm oven pineapple side up (about 225 degrees) and repeat the process (starting with buttering the griddle) until all pancakes are done and serve.
