In a medium-sized bowl, combine oat flour, brown rice flour, potato starch baking powder and vanilla extract and whisk to combine.
Pour in the milk and 3 tablespoons of maple syrup until you get a smooth batter.
Place a non-stick pan on medium-high heat. Pour in the batter and spread it around the pan.
Cook on one side until bubbles form on the surface, about 5 minutes. Then flip the pancake and cook for another 2-3 minutes. Break the pancake into pieces and add the extra tablespoon of maple syrup to the pan. Cook, stirring often, until the pancake pieces are golden brown and lightly caramelised.
Serve with cinnamon, maple syrup, apple sauce and fresh fruit.
