Blend the brown rice cereal and oats in a blender until it turns into a flour, then pour into a stand mixer bowl. Add the protein powder, flax, and salt, and mix on low speed.
Add the melted coconut oil, maple syrup, vanilla and stevia. Stir on low until fully incorporated.
Line an 8" brownie pan with parchment paper both ways and dump the mixture into the pan. Press it down to flatten.
Scoop the fruit spread onto the base and spread it out.
