Add the oats and cereal to a blender and blend until it's almost a flour. Dump the ingredients in a small bowl. Stir in the protein powder, flax, cinnamon, and salt.

In a large bowl, stir together the maple syrup, melted coconut oil, vanilla extract, stevia extract, and maple flavor. Mix into the dry ingredients.

Line a loaf pan with parchment paper (or use this chocolate mold), and press the mixture inside until compact. Refrigerate for 2 hours, then slice and serve!
