Preheat your oven to 350 F.
Line your muffin tray with 6 paper muffin cases.
In a big bowl add the banana paste, the egg, coconut oil, honey, and lemon juice. Stir well until combined.
In another bowl add the oat flour, cinnamon and a pinch of salt. Stir and add it to the wet-ingredients bowl. Stir well to combine.
Fill your muffin cases two-thirds full and bake for 30-35 minutes.
You'll know they are ready when they are firm to touch and a skewer inserted in the middle comes out clean.
Leave them to cool for 5-10 minutes and they are ready to serve.
