The Benefits of Oatmeal
Did you know? Oats are among the healthiest grains on earth. Cool, huh! They’re a gluten-free whole grain and a great source of essential vitamins, minerals, fiber, antioxidants, and heart-healthy!
We always look for healthy alternatives to pre-packaged food, so when you bake oats into a bar, and it tastes this good--you can’t go wrong!
How To Make - 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!
Step 1 - Line Your Pan & Preheat Oven
In the first step, line your 8×8 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.
Step 2 - Mix Ingredients
Next, in a large bowl, mash your banana and then combine melted coconut oil and honey (or sugar if using). Add egg, baking soda, cinnamon, salt, and vanilla, mixing well. Add in oats and flour and mix until well combined. (Add any optional chocolate chips or chunks. See recipe notes for suggestions.)
Pro Tip: spray your measuring cup with non-stick spray before putting your honey in – it will slide right out!
Step 3 - Bake
Then, place the batter into your lined baking pan. Finally, bake your bars in the oven for 20-25 minutes until golden brown. **Don't overcook your bars, or they'll get too dry!
Your whole house should smell absolutely fantastic at this point!
Topping Your Banana Bars
If you want to take your bars to the next level, here's a little combo you must try!!
Take a tablespoon of creamy peanut butter and ¼ cup white chocolate and melt in the microwave. Once it's melted, place it in a Ziploc baggie and snip a corner, and then pipe it onto your Banana Oatmeal Squares.
Oatmeal Bar Perfection!
Recipe Tips & Tricks
- This oatmeal banana bar recipe is best if you use old-fashioned oats, not instant oats. The bars will get very dense otherwise.
- We like using the healthy option of whole wheat flour, but regular flour or a combination will also work.
- These bars are pretty sweet with honey and bananas, but you can substitute brown sugar if you prefer an even sweeter recipe.
- The possibilities for delicious add-ins for these banana bars are endless! Dried fruit, coconut, chocolate, caramel, nuts, and M&Ms will all work!
How to Store
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.
