Preheat oven to 350F. Line a baking sheet with parchment paper.
In a large bowl, mix the ground flax seeds, hemp seeds, and water to make the flax egg. Leave to soak for 5 minutes. Add in the maple syrup, vanilla, and coconut oil. Whisk to incorporate ingredients and set aside.
In a medium-sized bowl, combine the oats, cereal, rice flour, baking powder, baking soda, cinnamon, and sea salt. Add the dry ingredients to wet and stir until you get a uniform batter. Fold in the raisins.
Using your hand, scoop and squeeze the mixture into 1 ½” rounded balls onto the parchment paper. Flatten slightly into round disks using two fingers moistened with water. Place in the oven and bake for 15 minutes, until slightly browned. Remove from the oven and cool.
