Preheat an oven to 375℉. In a bowl of a stand mixer, combine the cassava flour, flax seeds, baking powder, salt, and sugar. In a small bowl, combine the milk, heavy cream, butter and eggs.
Pour the liquid into the dry mixture and mix together. Add the cheese and mix until fully incorporated.
Place parchment paper on a baking sheet and spray with non-stick spray. Scoop the batter out onto the baking sheet with a spoon. Bake for 20 minutes.
