Preheat your oven to 375°F (190°C) and lightly grease a small individual-sized oven-safe ramekin or baking dish with a touch of coconut oil.
In a medium mixing bowl, whisk together the rolled oats, vanilla protein powder, ground flaxseed, hemp hearts, baking powder, cinnamon, and sea salt until well combined.
Pour in the unsweetened soy milk and vanilla extract, stirring until the batter is smooth and the dry ingredients are fully hydrated.
Gently fold in half of the mixed berries, being careful not to over-mix so the batter doesn't turn entirely purple.
Transfer the mixture into the prepared baking dish and smooth the top with a spatula.
Scatter the remaining berries and the chopped raw pecans over the top, pressing them slightly into the batter.
Bake for 22-25 minutes, or until the edges are golden brown and the center is set to the touch.
Remove from the oven and let it cool for 5 minutes before serving to allow the texture to firm up.
