Why You’ll Love This Recipe
These bars are like having a soft banana oatmeal cookie in bar form — hearty, not too sweet, and easy to make in one bowl. They’re packed with wholesome rolled oats, naturally sweetened with banana and maple syrup, and you can toss in your favorite mix-ins like chocolate chips or chopped nuts for a personalized twist.
Ingredients
- 2 cups rolled oats
- 1 1/3 cup mashed banana (for banana-free, try these [Baked Oats])
- 6 tbsp water
- 1/2 tsp salt
- 3 tbsp pure maple syrup, agave, or honey OR stevia equivalent
- 3 tbsp oil, nut butter, or additional water
- 1 tsp pure vanilla extract
- Optional: handful chocolate chips, chopped nuts, etc.
Directions

- Prep the Oven & Pan
Preheat your oven to 350°F (175°C). Line an 8-inch square baking pan with parchment paper, or generously grease it to prevent sticking. - Mix the Ingredients
In a large mixing bowl, combine all the ingredients: rolled oats, mashed banana, water, salt, sweetener, oil (or alternative), and vanilla extract. Mix thoroughly until the ingredients are evenly incorporated. If using any mix-ins like chocolate chips or nuts, fold them in at this stage or sprinkle on top later. - Spread the Batter
Pour the oatmeal mixture into the prepared pan. Use a spatula to smooth out the surface so it bakes evenly. - Bake
Place the pan on the center rack of your preheated oven and bake for 20 minutes. - Let Sit in the Oven
Without opening the oven door, turn off the heat and let the bars sit in the warm oven for an additional 5 minutes. This helps them firm up while retaining a soft, moist texture. - Cool & Slice
Remove the pan from the oven and allow it to cool for at least 10 minutes. Slice into bars or squares once cooled.
