With just a handful of ingredients, you can create a delicious snack that satisfies your cravings without the guilt.

- 3 large ripe bananas (1 ½ cups mashed)
- ½ cup (120g) creamy almond butter*
- 2 cups (200g) rolled oats
- 1 cup (170g) chocolate chips
- 1 tsp pure vanilla extract
- ½ tsp sea salt
- 1 tsp ground cinnamon
- â…” cup (100g) chopped walnuts or pecans

Gear Checklist
Before you start, make sure you have the following gear on hand:
- Mixing bowl – for combining your ingredients
- Fork or potato masher – to mash the bananas
- Spatula – for mixing and spreading the mixture into the pan
- Baking dish (8×8 or 9×9) – to bake your bars
- Parchment paper – for easy removal of the bars from the pan
Stepwise Method: 4-Ingredient Banana Oatmeal Bars

Step 1: Preheat Your Oven
Begin by preheating your oven to 350°F (175°C). This ensures that the bars bake evenly and come out perfectly.
Step 2: Prepare Your Baking Dish
Line your baking dish with parchment paper, leaving some overhang for easy removal later. This step is essential for preventing your bars from sticking.
Step 3: Mash the Bananas
In a mixing bowl, mash the 3 ripe bananas using a fork or potato masher until smooth. You want to aim for a creamy consistency with minimal lumps.
Step 4: Mix in the Almond Butter
Add the creamy almond butter to the mashed bananas and mix until fully combined. This will create a rich, thick mixture that serves as the base for your bars.
Step 5: Combine the Dry Ingredients
In a separate bowl, combine the rolled oats, sea salt, ground cinnamon, and chopped walnuts or pecans. Stir these ingredients together to ensure even distribution.
Step 6: Combine Everything Together
Slowly fold the dry ingredient mixture into the wet banana-almond butter mixture. Stir gently until just combined. Be careful not to overmix; a few lumps are perfectly fine.
Step 7: Add Chocolate Chips
Fold in the chocolate chips and pure vanilla extract. This will give your bars a delightful sweetness and rich flavor.
Step 8: Spread in Baking Dish
Pour the mixture into your prepared baking dish, spreading it out evenly with a spatula. Use the back of the spatula to press it down firmly so that the bars hold their shape while baking.
Step 9: Bake
Place the dish in the preheated oven and bake for about 25-30 minutes, or until the edges are golden brown and the center is set.
Step 10: Cool and Slice
Once baked, remove the dish from the oven and allow the bars to cool completely in the pan. Use the parchment paper overhang to lift the bars out, then slice them into squares or rectangles. Store or enjoy immediately!
Season-by-Season Upgrades

These 4-Ingredient Banana Oatmeal Bars are versatile and can be easily adapted to suit the seasons. Here are some ideas to upgrade your bars:
- Spring: Add fresh blueberries or strawberries for a seasonal burst of flavor.
- Summer: Mix in shredded coconut for a tropical twist.
- Fall: Incorporate pumpkin puree and spices like nutmeg for a festive flavor.
- Winter: Stir in dried cranberries or chopped dates for added sweetness and chewiness.
Behind the Recipe
The inspiration for these 4-Ingredient Banana Oatmeal Bars comes from a desire to create a snack that is not only easy to prepare but also healthy and satisfying. As someone who loves to bake but often finds themselves short on time, I wanted a recipe that would deliver on flavor without requiring a long list of ingredients. These bars are perfect for busy mornings or when you need a quick energy boost during the day. Plus, they are a fantastic way to use up overripe bananas!
Storing, Freezing & Reheating
Store your homemade 4-Ingredient Banana Oatmeal Bars in an airtight container at room temperature for up to 3 days. For longer storage, you can freeze the bars. Simply wrap them individually in plastic wrap and place them in a freezer-safe bag. They will last up to 3 months in the freezer. When you’re ready to enjoy them, just thaw at room temperature or microwave for a few seconds until warmed through.
Handy Q&A
Can I use quick oats instead of rolled oats?
Yes, you can use quick oats. However, the texture of the bars may be slightly different, as quick oats absorb moisture more quickly than rolled oats.
What can I substitute for almond butter?
Any nut butter, such as peanut butter or cashew butter, will work well in this recipe. For a nut-free option, sunflower seed butter is a great alternative.
How do I know when the bars are done baking?
The bars are done when the edges are golden brown and the center is set. A toothpick inserted in the center should come out clean or with just a few moist crumbs.
Can I add protein powder to these bars?
Yes! You can add a scoop of your favorite protein powder to the mixture for an extra protein boost. Just be aware that it might change the texture slightly, so you may need to adjust the wet ingredients accordingly.
