Easy Oatmeal Bars Recipe

Okay, so I’ve been making these Easy Oatmeal Bars Recipe for ages, and let me tell you, they’re not just “good,” they’re “hide-them-from-the-kids-and-husband” good. Seriously, these bars are like sunshine in a bite, packed with oats, and just the right amount of sweetness. They’re perfect for breakfast, a snack, or even dessert when you’re trying to be somewhat healthy. And guess what? They’re so easy, even I can’t mess them up… usually.
My husband, bless his heart, isn’t usually the biggest fan of “healthy” snacks. But these? He devours them. One time, I made a double batch for a bake sale, and half of them mysteriously disappeared before they even made it out the door. Let’s just say my husband had a very sheepish grin that day. Now, I make them specifically so he can grab one on the way to work. It’s my little way of sending him off with a little homemade love…and keeping him away from the donut shop.
Why You’ll Love This Easy Oatmeal Bars Recipe
Okay, real talk, why are these bars the bomb?
- They’re ridiculously easy. Seriously, dump, mix, bake. My kind of recipe.
- They’re adaptable. Throw in whatever you have in the pantry—nuts, chocolate chips, dried fruit… you name it!
- They’re a crowd-pleaser. Even picky eaters (like my nephew, ugh) inhale these things.
- They’re kinda healthy-ish. I mean, they have oats! So that’s gotta count for something, right?
- Perfect grab-and-go breakfast!
How to Make It
Alright, let’s get down to business. So, basically, you’re gonna melt the butter (or coconut oil if you’re feeling fancy) in a big bowl. Then, you’re gonna dump in the brown sugar and granulated sugar. I usually use brown sugar because it gives it that nice, chewy texture, but sometimes I only have white, and it works just fine, don’t stress.
Next, crack in the eggs and vanilla extract. Mix it all up until it’s smooth. Now, this is important: don’t overmix! It makes the bars tough, and nobody wants tough bars.
In another bowl, whisk together the flour, oats, baking soda, and salt. Then, gradually add the dry ingredients to the wet ingredients, mixing until just combined. Resist the urge to keep stirring!

Now for the fun part: add-ins! Chocolate chips are always a good idea. I also like to throw in some chopped nuts or dried cranberries. Sometimes I even add a sprinkle of cinnamon. Just go wild!
Pour the mixture into a greased baking pan (I use a 9×13 inch pan). Spread it out evenly and pop it in the oven. Bake until golden brown and a toothpick inserted into the center comes out clean.
Let them cool completely before cutting into squares. This is the hardest part because the smell is divine, but trust me, they’re easier to cut when they’re cool. Plus, they get even chewier!
Ingredient Notes
- Oats: Old-fashioned rolled oats are your best bet. Quick oats work in a pinch, but they don’t give you that same chewy texture. Steel-cut? Forget about it. Trust me.
- Brown Sugar: This is what gives the bars that delicious, caramel-y flavor. If you only have white sugar, you can use that, but add a tablespoon of molasses to mimic the brown sugar flavor. Or don’t! I’ve skipped it. The world didn’t end.
- Butter: I usually use unsalted butter, but if you only have salted, just skip the extra salt in the recipe. Easy peasy.
- Chocolate Chips: Semi-sweet, milk chocolate, dark chocolate… whatever floats your boat! I’ve even used peanut butter chips before and it was AMAZING.
Recipe Steps:
- Melt butter in a large bowl.
- Add brown sugar and granulated sugar to the melted butter and mix well.
- Incorporate eggs and vanilla extract, mixing until smooth.
- Whisk together flour, oats, baking soda, and salt in a separate bowl.
- Gradually add dry ingredients to wet ingredients, mixing until just combined.
- Stir in chocolate chips and any other desired add-ins.
- Pour mixture into a greased baking pan and spread evenly.
- Bake in a preheated oven until golden brown and a toothpick inserted comes out clean.
- Cool completely before cutting into squares.
What to Serve It With
These are awesome on their own, obviously. But if you’re feeling fancy, you could serve them with a scoop of vanilla ice cream or a dollop of whipped cream. Or, you know, just grab one straight from the pan while no one’s looking. No judgment here. I like to grab a bar and a cup of hot coffee for my morning commute.
Tips & Mistakes
- Don’t overbake! They should be golden brown, but still a little soft in the center. Overbaking leads to dry, crumbly bars, and nobody wants that.
- Grease your pan! Trust me on this one. Otherwise, the bars will stick to the pan and you’ll have a crumbly mess on your hands. I usually use cooking spray, but you can also grease it with butter or shortening.
- Let them cool completely before cutting. I know, it’s tempting to dig in right away, but they’re much easier to cut when they’re cool. Plus, they get chewier as they cool!
- Don’t be afraid to experiment with add-ins! The possibilities are endless.
Storage Tips
Store these bad boys in an airtight container at room temperature. They’ll stay fresh for about 3-4 days… if they last that long. Honestly, in my house, they’re usually gone within 24 hours. You can also freeze them for up to 2 months. Just wrap them individually in plastic wrap and then place them in a freezer bag. And, yeah, I’ve eaten them cold straight from the fridge for breakfast. Don’t judge!
Variations and Substitutions
- Nuts: Walnuts, pecans, almonds… go nuts! (See what I did there?)
- Dried Fruit: Cranberries, raisins, chopped apricots… the options are endless!
- Chocolate: White chocolate chips, chunks of dark chocolate, a drizzle of melted chocolate…yes, please!
- Spices: A sprinkle of cinnamon, nutmeg, or even a pinch of cardamom can add a warm, cozy flavor.
- Nut butter: Swirl a bit of peanut butter, almond butter, or even tahini into the batter for a nutty twist.
- Honey/Maple Syrup: Instead of brown sugar. It will change the texture slightly, but sometimes you gotta use what you got, right?
