Ingredients and Substitutes

Bananas (3) – Ripe bananas are best here.

Eggs (2) – It is best to use free-range, organic eggs.

Vanilla extract (1 tsp) – Vanilla gives a nice flavor to this dish, and I recommend not using any substitutes.

Butter (7 oz) – Try not to use shortening or other alternatives.

Honey (1/4 cup) – If you don’t have honey, you can substitute it with maple or corn syrup.

Cinnamon (1/2 tsp) – Cinnamon gives such a warming touch to these bars. I recommend adding it, but you can totally go without it.

Baking soda (1/4 tsp) – Needed to give a bit of “air” to the bars.

Rolled oats (4 cups and 2 tbsp) – I recommend rolled oats for a chewier texture. However, quick oats can also be used.

Chocolate chips (1/2 cup) – Dark or milk

How to Store and Freeze?

It is best to store these chewy bars in an airtight container in the fridge. They will keep well for up to 5 days.

If you want to freeze them, I suggest wrapping individual bars into parchment paper first. Then, store them in an airtight container or freezer bag. If properly frozen, they will keep well for up to 6 months.

If you follow the method carefully, chewy and soft bars are guaranteed. But here are some extra tips:

  • Use room-temperature eggs so that the ingredients can combine cohesively.
  • Press the dough well when transferring it to the baking dish. That way, it will bake evenly.
  • Do not overbake. The bars will continue to cook even when out of the oven, so make sure to remove them as soon as they turn brown around the edges.
  • Allow to cool before cutting into bars. I cannot stress this enough! If it is still hot, the bars are not set yet and will break into pieces.
