In a small saucepan, mash the banana with a fork until mostly smooth.
Add the coconut milk, cinnamon, and sea salt. Stir well to combine.
Heat gently over medium-low heat, stirring frequently, until the mixture thickens—about 5 to 7 minutes.
For a thicker texture, stir in coconut flour and continue to cook another 1-2 minutes.
Pour into a bowl and top with your favorite AIP-friendly additions. Serve warm and enjoy.
