Ingredients You’ll Need

The beauty of Baked Oatmeal Bars is how incredibly simple and wholesome the ingredients are. Each one is carefully chosen to deliver hearty flavor, satisfying texture, and a touch of natural sweetness. Here’s everything you’ll need to bring your new favorite bars to life:

• Rolled oats: The base of these bars, rolled oats add that signature chewy texture and make them filling and wholesome.
• Mashed banana: Naturally sweet and moist, banana binds everything together. For a banana-free version, you can swap in baked oats as suggested!
• Water: Keeps everything nice and moist without weighing the bars down.
• Salt: Just a pinch brings all the flavors into clear, delicious focus.
• Pure maple syrup, agave, honey, or stevia: Choose your sweetener—each option gives its own unique flavor, so pick your favorite.
• Oil, nut butter, or extra water: Pick your source of richness: oil for tenderness, nut butter for a protein boost and subtle flavor, or even more water for a lighter touch.
• Pure vanilla extract: Adds that irresistible bakery aroma and warmth.
• Optional chocolate chips, chopped nuts, etc.: Personalize your bars with a sprinkle of chocolate, crunch of nuts, or anything else your heart desires.

How to Make Baked Oatmeal Bars

Step 1: Prep Your Pan and Oven

Start by preheating your oven to 350 F. Line an 8-inch square pan with parchment paper for easy removal, or give it a generous coat of nonstick spray or oil if you prefer. This step ensures your bars come out clean and whole every time, without any stubborn sticking.

Step 2: Stir Together the Ingredients

Grab a large bowl and stir together the rolled oats, mashed banana, water, salt, sweetener of your choice, oil or nut butter (or water), and vanilla extract. Mix until everything is evenly combined. This is the moment to fold in any extras—think chocolate chips, chopped nuts, or even dried fruit for a personalized touch.

Step 3: Smooth and Sprinkle

Pour the thick and hearty mixture into your prepared pan. Use a spatula to smooth the top so it bakes evenly. If you’re feeling festive, sprinkle a few extra chocolate chips or nuts on top before baking—they’ll get all melty and toasty in the oven.

Step 4: Bake and Rest

Bake the bars for 20 minutes. Then, here’s the key for perfect, tender bars: turn off the oven and leave the pan inside for 5 more minutes, door closed, letting the residual warmth finish the job and firm up the bars. This little pause gives them the best texture!

Step 5: Slice and Savor

Carefully lift the bars from the pan using the parchment or just slice right in if greased. Cut into perfect squares or rectangles, ready to be devoured for breakfast, dessert, or a pick-me-up snack.

How to Serve Baked Oatmeal Bars

Garnishes

A simple dusting of cinnamon or a drizzle of extra maple syrup can turn these Baked Oatmeal Bars into a breakfast that feels like a hug. For a fancier finish, add a dollop of Greek yogurt, a sprinkling of fresh berries, or a spoonful of nut butter on top.

Side Dishes

Pair your Baked Oatmeal Bars with a crisp apple salad, a frothy latte, or a tall glass of milk for a seriously satisfying breakfast or snack. For brunch gatherings, offer fruit salad and scrambled eggs on the side for a complete and colorful spread.

Creative Ways to Present

Serve Baked Oatmeal Bars warm, wrapped in parchment for a grab-and-go treat, or stack them on a rustic wooden board with bowls of toppings for a build-your-own breakfast bar. For dessert, try cutting them into smaller bite-size squares and serve with an ice cream scoop on top—a playfully sweet twist!

Make Ahead and Storage

Storing Leftovers

If you’re lucky enough to have leftovers, tuck them away in an airtight container in the fridge. These Baked Oatmeal Bars keep beautifully for 3 to 4 days, maintaining their soft texture and yummy flavor even after a few days’ rest.

Freezing

For longer storage, layer cooled bars between sheets of parchment or wax paper and freeze in a container or freezer bag. They’ll stay fresh for up to a few months—simply thaw overnight in the fridge or at room temperature for a perfect make-ahead treat.

Reheating

To recapture that fresh-from-the-oven magic, pop your Baked Oatmeal Bars into the microwave for 10 to 15 seconds each, or warm gently in a low oven. They’ll taste just as comforting as the day you baked them!

FAQs

Can I make these Baked Oatmeal Bars gluten-free?

Absolutely! Simply use certified gluten-free rolled oats and check the labels for any add-ins. These bars are incredibly adaptable and perfect for those with dietary restrictions.

What can I use instead of banana?

If you’re not a fan of banana or want to try something different, unsweetened applesauce or pumpkin puree works as a lovely substitute. Both bring moisture and a subtle natural sweetness to your Baked Oatmeal Bars.

How do I prevent the bars from being too dry or crumbly?

Be sure to measure your ingredients carefully, especially the banana or alternative. Adding just the right amount of moisture helps keep the bars chewy and cohesive without being soggy. Don’t skip that final 5-minute rest in the oven, either!

Can I double the recipe?

You sure can! Just bake the bars in a 9×13-inch pan and watch your cook time—it may need a few extra minutes. This is a great option for meal prepping or feeding a houseful of hungry tummies.

What fun add-ins work best for these bars?

Let your imagination run wild! Try dried cranberries, sunflower seeds, shredded coconut, or even a pinch of warming spices like cinnamon or nutmeg. The base recipe for Baked Oatmeal Bars is a blank canvas for your culinary creativity.
