Mash ripe bananas and mix with honey, vanilla, and coconut oil.
Combine whole wheat flour, baking soda, cinnamon, and salt in a bowl.
Gradually mix dry ingredients into the wet mixture until batter forms.
Grease a cake tin and pour the banana bread batter into it.
Place the tin on a stand inside the pressure cooker.
Cook without the whistle for 30-40 minutes on medium heat.
Cool, slice, and enjoy your healthy no-sugar banana bread.
