Description
Delicious and chewy banana oatmeal bars, perfect for a quick snack or breakfast.
Ingredients
- 1 1/2 cups mashed bananas (approx. 3 bananas)
- 1/2 cup nut butter (peanut butter or cashew butter, ensure it’s well mixed for best results)
- 2 cups rolled oats
- 11/2 teaspoon cinnamon
- 11/2 teaspoon vanilla extract
- 3 tablespoons maple syrup
- 1 cup chocolate chips (or replace with walnuts, pumpkin seeds, sunflower seeds, or raisins)
- 1/21/2 teaspoon salt
- 11/2 teaspoon vanilla extract
Instructions
- Mix Wet Ingredients: Start by mixing the mashed bananas with your nut butter and the vanilla extract. Make sure there are no big chunks of banana left; otherwise, the texture will be off.
- Stir in Oats: Next, add the rolled oats to your banana mix, stirring gently until well-blended. A nice, thick consistency should form, which is crucial for chewy, hearty bars. Avoid using instant oats here; they tend to make the mixture too mushy.
- Add Mix-Ins: Now it is time to toss in any optional mix-ins, like nuts or seeds. Make sure not to go overboard, as too many add-ins can throw off the consistency.
- Spread Into Pan: Spread your mixture evenly into a lined baking pan, smoothing it out with a spatula. Make sure the top is level and slightly shiny from the bananas to ensure even baking.
- Bake Until Set: Pop the pan into a preheated oven and bake until the edges start to turn golden brown. Allow the bars to bake fully to ensure they hold together well.
- Cool and Slice: Once the bars are out, let them cool completely before cutting them into squares. This patience is essential for them to firm up; otherwise, they might fall apart when sliced.
Notes
- Storage Tips: Store the banana oatmeal bars in an airtight container in the fridge for up to 5 days or at room temperature for around 2 days. For longer storage, wrap individually in plastic wrap and freeze for 2-3 months.
- Expert Tips: If the bars feel too soft, waiting at least 30 minutes for them to cool completely will help them firm up. Stick with rolled oats for the best texture and avoid instant oats that may lead to a mushy bar. Use binder clips to secure the parchment paper in place while mixing the ingredients, preventing any shifting.
- Reheating Instructions: Reheat in the microwave for 15-20 seconds if desired.
- Serving Suggestions: Pair with yogurt for a balanced breakfast or serve with a drizzle of honey or nut butter. Enjoy with fresh fruit slices on the side.
- Recipe Variations: Replace chocolate chips with dried fruit like cranberries, or add spices like nutmeg or ginger for a flavor twist. Incorporate different nut butters for varied tastes.
- Ingredient Notes: When selecting bananas, use overripe ones for the best sweetness. If you do not have nut butter, peanut butter or cashew butter can be used effectively. Substitution options for chocolate chips include walnuts, pumpkin seeds, sunflower seeds, or raisins based on personal preference.

Ingredient Notes
- Mashed bananas: These puppies are the star! Go for ripe ones; they’re sweeter and easier to mash. You can use applesauce as a swap if you prefer.
- Nut butter: It adds creaminess and a nutty kick. I love almond or peanut butter! If you’re nut-free, sunflower seed butter works too.
- Rolled oats: They give the bars their chewy texture. Make sure to stick with rolled, not quick oats, for the best results. No substitutes unless you go gluten-free with certified oats!
- Cinnamon: A sprinkle of this spice brings warmth and depth to the bars. You can easily swap it out for nutmeg if you’re feeling adventurous!
- Vanilla extract: This adds that warm, sweet flavor we all love! Always grab pure vanilla over imitation for a richer taste; skipping it isn’t the same.
- Maple syrup: It sweetens things up and gives a lovely flavor. If you’re in a pinch, honey can work, but it’ll tweak the taste a bit.
- Chocolate chips: For that sweet, melty goodness! Use dark or semi-sweet to balance the natural sweetness of the bananas. You can swap them for dried fruit too.
- Salt: Just a pinch enhances all the flavors! I find that using unsalted nut butter and adding a tiny bit of salt balances the sweetness nicely.
Recipe Tips
- If the bars feel too soft, waiting at least 30 minutes for them to cool completely will help them firm up.
- When using rolled oats, it’s best to avoid instant oats which may lead to a mushy texture; stick with the rolled variety.
- If your parchment paper shifts during mixing, using binder clips to secure it will keep things in place while you work.
- For added variety, incorporating a half cup of nuts or seeds can be a nice touch, enhancing the bars’ texture and nutrition.
- If you’re looking to use up overripe bananas, mashing three medium-sized ones will yield about 1½ cups, perfect for this recipe.
Serving Suggestions
These banana oatmeal bars work well as a breakfast option or snack. Pair them with yogurt, fresh fruit slices, or a drizzle of nut butter.
These bars can serve as a base for granola or crumble toppings in other recipes. They also make a nutritious addition to lunchboxes or meal prep for the week.
Add a drizzle of honey on top for added sweetness if desired. A sprinkle of cinnamon also complements these bars nicely to enhance flavor.
Recipe variations
- You can substitute mashed bananas with unsweetened applesauce in equal amounts for a different flavor profile.
- Add ½ teaspoon nutmeg or ½ teaspoon ginger to the mixture for a spiced twist.
- Either use peanut butter or almond butter for a distinct taste and texture.
- If you want to make a larger batch, use 2 cups mashed bananas, 1 cup nut butter, and 4 cups rolled oats.
