- Butter - butter or melted coconut oil for healthy fats.

- Baking soda - a leavening agent to give the batter a little lift.
- Cinnamon - a hint of warm spice elevates the recipe.
- Sea salt
- Pure vanilla extract - we prefer real vanilla extract.
- Whole wheat flour - or a combo of all-purpose white and whole wheat, depending on your preference)

Substituions & Variations
- FLOUR OPTIONS. We like using the healthy option of whole wheat flour, but regular all-purpose flour or a combination also works. You can also use a 1:1 gluten-free flour option. Try our Banana Almond Butter Muffins if you need a gluten-free recipe.
- SWEETENER - you can use honey or maple syrup in your bars. If you prefer a sweeter bar, use ¾ cup brown sugar.
The possibilities for delicious add-ins to change up these banana bars are endless! Dried fruit, coconut, chocolate, caramel, nuts, and M&Ms will all work! Add ground flax seeds if you like.
Topping Idea
In addition to topping with a handful of pumpkin seeds, if you want to take your bars to the next level, here's a sweet little combo to try!! Make them Peanut Butter Banana Oatmeal Bars.
- Mix a tablespoon of creamy natural peanut butter (or almond butter) and ¼ cup of white chocolate in the microwave.
- Once melted, place the mixture in a Ziploc baggie, snip a corner, and drizzle it onto your Banana Oatmeal Squares.
Step-By-Step Instructions
Can you believe it takes only one bowl and one pan to make this recipe?
The banana flavor in these Banana Oatmeal Bars makes it a classic. Let's get baking!
- Line Your Pan & Preheat Oven. Line your 8×8 baking pan with parchment paper. This makes it easy to get your bars out when they’re done cooking. You can also spray your pan with a non-stick spray as an alternative. Then, preheat your oven to 350 degrees F.
- Mix Ingredients. Next, in a large bowl, mash your banana with a fork or potato masher. Then combine the other wet ingredients, melted coconut oil, and honey (or sugar if using) (Image 1). Add egg, baking soda, cinnamon, salt, and vanilla, mixing well (Image 2). Add dry ingredients—rolled oats and flour and mix until well combined (Image 3). (Add any optional chocolate chips or chunks. See recipe notes for suggestions.)
- Bake. Place the batter into your prepared baking pan (Image 4). Finally, bake oatmeal bars in the oven for 20-25 minutes until golden brown. **Don't overcook your bars, or they'll get too dry!
- Cool. Remove from the oven and let the bars cool completely in the baking dish. Once cooled, lift the parchment paper with the bars from the dish and transfer them to a cutting board.
Your whole house should smell absolutely fantastic at this point!
PRO TIP: spray your measuring cup with non-stick spray before putting your honey in – it will slide right out!
Expert Tips
- PAN: Use an 8-inch square baking dish for the recipe or if you'd like thinner bars, use a 9-inch square. Remember to line your pan with parchment paper so the bars come out of the baking dish easily!
- OATS. We recommend using old-fashioned oats instead of instant or quick oats in this oatmeal banana bar recipe for optimal results. Using quick oats may result in overly dense bars.
- ADD-INS. The possibilities for delicious add-ins for your banana bars are endless! Dried fruit, coconut, chocolate, caramel, nuts, and M&Ms will all work!
How to Store
We recommend making a double batch and storing some for later!
To Freeze: Bake as directed and allow your Banana Oat Bars to cool completely. Cut into bars, then wrap individually in foil or plastic. Place wrapped bars in a freezer bag for later. Thaw for at least one hour before eating.
To Store: Layer the bars between waxed paper in an airtight container. Store in the refrigerator for 3 - 5 days. Bring back to room temperature before serving.
