Lightly coat a medium-size pan with a spritz of olive oil.
In a medium-size bowl, whisk together all ingredients except the blueberries and Flora-Key.
Gently fold 1/2 cup of the blueberries into the batter.
Heat the pan over medium heat.
Using a tablespoon, ladle the chia mixture into the pan.
Cook until tiny bubbles form on the surface and the chiacakes are solid enough to turn.
Carefully flip the chiacakes, cooking until done; transfer to a plate and keep warm.
Repeat the process with the remaining batter, spritzing the pan with olive oil as needed.
Garnish with the remaining blueberries and sprinkle with Flora-Key.
