Preheat your oven to 350°F (175°C) to ensure even baking and a crunchy texture.
Line a baking sheet with parchment paper to prevent sticking and ease cleanup.
In a mixing bowl, combine almond flour, coconut flour, 4 tablespoons monk fruit sweetener, cinnamon powder, and salt. Whisk until well blended.
In a separate bowl, beat the egg white until slightly frothy. Add melted coconut oil and mix well.
Pour the wet mixture into the dry ingredients and stir until fully combined.
Transfer the mixture to the prepared baking sheet and spread into an even layer, not too thick.
Bake for 15-20 minutes, until edges are golden brown and the center is firm.
Remove from oven and let cool on the baking sheet for a few minutes, then transfer to a cooling rack to cool completely.
Once cooled, break the cereal into bite-sized pieces. Store in an airtight container for up to a week.
