Preheat the oven to 350F (180C). Grease slightly 3 ramekins, each of 1 cup (240ml) capacity or 4-6 smaller ramekins.
Place the oats into the bowl of a food processor and process until turn into fine flour.
In a large bowl, mash the banana using a fork. Add the eggs, honey, salt and vanilla extract and mix to combine.
Add the buttermilk and continue mixing until combined.
Add the baking powder and oat flour and mix well to combine.
Divide the batter evenly into the prepared ramekins.
Top with blueberries, raspberries and pecans. You can use any other seasonal fruits you like best.
Bake for 25-30 minutes until a toothpick inserted into the center comes out clean.
Serve as is or alongside some Greek yogurt and honey.
