Place all ingredients except raspberries and olive oil spray in a bowl and whisk until combined.
Gently chop 1/2 cup of raspberries and fold into batter.
Lightly spritz a medium skillet with the olive oil spray and place over medium heat.
Ladle the flaxcake mixture into the pan using a tablespoon.
Cook the flaxcakes until tiny bubbles form on the surface and the cakes are solid enough to turn.
Carefully flip the flaxcakes, cooking until done; repeat with remaining batter.
Top the cooked flaxcakes with the remaining berries.
