Pro Tips for the Best Baked Oatmeal Bars
Before we get into the recipe, let’s go over a few pro tips to make sure your baked oatmeal bars turn out perfectly every time!
1. Use Old-Fashioned Rolled Oats
For the best texture and flavor, old-fashioned rolled oats are your go-to choice. They absorb the right amount of liquid and give your bars a chewy, hearty texture. Quick oats are a good substitute if you’re in a pinch, but they’ll give a slightly different result.
2. Don’t Overmix the Batter
When mixing your ingredients, be careful not to overmix the batter. Overmixing can lead to dense, heavy bars. Stir just enough to combine the ingredients and make sure everything is evenly distributed.
3. Customize the Sweetness
You can control the sweetness of your baked oatmeal bars depending on your taste. I personally love using maple syrup, but honey, agave, or even mashed bananas work wonderfully too. Start with less sweetener and add more if needed!
4. Let the Bars Cool Completely Before Cutting
After baking, let your baked oatmeal bars cool completely before cutting them into squares. This will ensure they hold together well and don’t crumble.
What You’ll Need: Ingredients for Baked Oatmeal Bars
Here’s what you need for the most delicious baked oatmeal bars:
- 2 cups rolled oats – The base of your bars.
- 2 ripe bananas – Adds natural sweetness and moisture.
- 2 eggs – For binding.
- 1/2 cup milk – You can use regular milk or plant-based milk for a vegan option.
- 1/4 cup maple syrup – Or your choice of sweetener.
- 1 teaspoon vanilla extract – Adds a lovely flavor.
- 1/2 teaspoon ground cinnamon – A hint of spice that pairs perfectly with oats.
- 1/4 teaspoon salt – To balance the flavors.
- 1/2 cup add-ins – Optional: Chocolate chips, chopped nuts, dried fruit, seeds, etc.
That’s it! Simple, wholesome ingredients that come together to create a snack you’ll love.
Step-by-Step Instructions for Baked Oatmeal Bars
Now, let’s get baking! These baked oatmeal bars come together in a few easy steps.
Step 1: Preheat the Oven and Prepare the Pan

Preheat your oven to 350°F (175°C). Line a baking pan (about 8×8 inches) with parchment paper or lightly grease it to prevent sticking.
Step 2: Mash the Bananas
In a large bowl, mash the ripe bananas with a fork until smooth. Bananas not only add sweetness but also help keep the bars moist.
Step 3: Add Wet Ingredients
To the mashed bananas, add the eggs, milk, maple syrup, and vanilla extract. Whisk everything together until well combined.
Step 4: Mix the Dry Ingredients
In another bowl, combine the oats, cinnamon, and salt. Once mixed, fold the dry ingredients into the wet ingredients. Stir until everything is just combined (don’t overmix!).
Step 5: Add Your Favorite Mix-ins

Now’s the fun part! Stir in any add-ins you like—chocolate chips, chopped nuts, dried fruit, or seeds. Feel free to get creative!
Step 6: Bake
Pour the batter into your prepared baking pan and spread it out evenly. Bake for 20-25 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.
Step 7: Cool and Slice
Let the bars cool in the pan for about 10 minutes before transferring them to a wire rack to cool completely. Once cool, slice them into squares or bars.
Flavor Variations for Baked Oatmeal Bars

One of the best parts about making baked oatmeal bars is how easy it is to customize them. Here are a few delicious variations:
1. Peanut Butter & Banana
For a classic combo, add peanut butter to the wet ingredients and extra banana slices to the batter for added flavor and healthy fats.
2. Berry Bliss
Add in fresh or frozen berries like blueberries, raspberries, or strawberries for a fruity twist. You can even swirl in some fruit preserves for extra sweetness!
3. Cinnamon Apple
Dice an apple and stir it into the batter along with some cinnamon. These bars will taste like a warm apple pie!
4. Chocolate Chip & Walnut
For a decadent touch, add chocolate chips and walnuts to your baked oatmeal bars. This is the perfect way to satisfy your sweet tooth while still keeping things healthy.
5. Vegan & Gluten-Free
To make these baked oatmeal bars vegan, use flax eggs instead of regular eggs and opt for plant-based milk. To make them gluten-free, make sure to use certified gluten-free oats.
