Add flax egg ingredients to a small mixing bowl and allow to sit for 5 minutes to gel. Add the remaining ingredients to the bowl except for the raspberries and whisk vigorously with a fork until well combined. Spray a skillet with nonstick spray and heat over medium. Once warm, drop the pancakes batter onto the skillet into several small pancakes. Spread with the back of a spatula to make a thin circle. Cook for 10 minutes, flipping once halfway through. Serve immediately with fresh raspberries and maple syrup.
