Line a brownie pan with parchment paper both ways.
In a large mixing bowl, stir together the cereal, oats, flax and salt.
In a large microwave-safe bowl, stir together the almond butter, rice syrup, vanilla paste, and extracts. Microwave at 30-second intervals, stirring between each one, until mixture is runny.
Add the protein powder to the wet ingredients, spoonful by spoonful, until incorporated. Scoop this mixture over the dry ingredients and fold together. Scoop this into the pan and flatten.
