In a small saucepan, combine the mixed berries and water over medium heat, simmering until the berries burst into a thick, glossy compote.
In a medium bowl, whisk together the almond flour, flaxseed meal, baking powder, cinnamon, and sea salt until well combined.
In a separate bowl, beat the whole egg, egg whites, and vanilla extract until frothy.
Gently fold the wet ingredients into the dry mixture, stirring until a consistent batter forms.
Heat the coconut oil in a non-stick skillet over medium-low heat.
Pour the batter into the skillet to form four small pancakes, cooking until bubbles form on the surface and edges are set.
Carefully flip the pancakes and cook for another 2 minutes until golden brown and firm to the touch.
Plate the pancakes and top with the Greek yogurt and warm berry compote.
