Step‑by‑Step Instructions for Banana Oatmeal Bars
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven warms up, line a 9×9-inch baking pan with parchment paper, ensuring there’s excess hanging over the edges for easy removal later. This step sets the stage for your Banana Oatmeal Bars to bake evenly and prevents sticking.
Step 2: Mix the Ingredients
In a large mixing bowl, mash approximately 3 ripe bananas until smooth, then add your choice of nut butter, rolled oats, cinnamon, vanilla extract, maple syrup, chocolate chips, and a pinch of salt. Mix thoroughly with a spatula or a wooden spoon for about 2-3 minutes until everything is well-cohesive and the mixture resembles a thick batter.
Step 3: Spread the Mixture
Pour the banana mixture into the prepared baking pan, using a spatula to spread it evenly. Press the mixture down firmly to create a compact layer; this helps the bars hold their shape once baked. For extra indulgence, you can sprinkle additional chocolate chips on top before baking.
Step 4: Bake to Perfection
Place the baking pan in your preheated oven and bake for 18-20 minutes. Keep an eye on the edges; they should turn a lovely golden brown as the mixture sets. The center should feel firm to the touch while still being slightly soft for that perfect chewy texture in your Banana Oatmeal Bars.
Step 5: Cool and Slice
Once baked, remove your pan from the oven and let it cool completely in the pan on a wire rack. This could take about 30 minutes. Once cooled, lift the bars out using the parchment paper and cut them into 16 squares. Enjoy your freshly made, wholesome Banana Oatmeal Bars!

Banana Oatmeal Bars Recipe FAQs
What type of bananas should I use for Banana Oatmeal Bars?
The best bananas for this recipe are overripe ones, as they provide maximum sweetness and moisture. If your bananas aren’t quite ripe enough, you can speed up the ripening process by placing them in a paper bag with an apple for about 1-2 days.
How should I store Banana Oatmeal Bars?
These bars can be stored in an airtight container in the refrigerator for up to 1 week. For optimal freshness, it’s best to keep them refrigerated. If you want to keep them longer, you can freeze them!

When you’re ready to enjoy, simply thaw them in the fridge overnight or let them sit at room temperature for a couple of hours.
What do I do if my bars are too dry or crumbly?
If your bars turn out dry, it’s likely that the bananas weren’t mashed thoroughly enough, or the baking time was too long. Next time, ensure your bananas are well mashed and keep an eye on the bars while baking. If they’re baked too long, they can dry out. Aim for a golden edge but a slightly soft center for that chewy texture.
Are there any dietary considerations I should be aware of?
Yes! If you’re making these bars for people with allergies, be mindful if you’re using nut butters, as some individuals have nut allergies. For gluten-free options, make sure to use certified gluten-free oats to accommodate those dietary needs. Always double-check ingredient labels if you’re uncertain!
Can I make substitutions in the recipe?
Very! You can substitute the nut butter with allergies in mind, using sunflower seed butter if needed.
