Ingredient Notes
- Melted butter - the butter gives these bars a nice rich flavor, but you can also use coconut oil.
- Honey - you use honey in place of processed white sugar. Agave or maple syrup can also be used as a sweetener.
- Eggs - eggs act as a binder in the recipe, and large eggs are best.
- Baking soda
- Salt - we like sea salt or pink Himalayan salt.
- Pure vanilla extract - we always say the better the ingredients, the better the end result 😉
- Old-fashioned oats - traditional rolled oats bake up the best for a chewy texture. Quick oats tend to get too dense.
- Whole wheat flour - you can use all-purpose flour or a combination of regular whole wheat and white flour.
PRO TIP: If you prefer a moist oatmeal breakfast bars recipe, add ½ cup of apple sauce to the wet ingredients.
Variations
VEGAN Oatmeal Bars: Make the bars vegan by replacing the egg with a flax egg, using maple syrup, not honey, and substituting coconut oil for the butter.
GLUTEN-FREE: Make the bars GF by using certified gluten-free oats and using a 1:1 flour substitute.
Add-ins
The possibilities for tasty add-ins for this soft-baked oatmeal breakfast bar recipe are endless!
- Dried Fruit: Try any dried fruit (raisins, cranberries, etc.).
- More Spice: Add up to a teaspoon of cinnamon or nutmeg.
- More Texture: Shredded coconut will do the trick!
- Chocolate: Dark chocolate chips or chocolate chunks. Or you can make our Chocolate Oatmeal Bar recipe.
- Rich Flavor: Try caramel chips.
- Nuts or Seeds: Chia seeds, sunflower seeds, or try nuts like walnuts or pecans.
- Sweetness: Add in M&Ms or Reese's Pieces.
You can also drizzle some pure maple syrup or almond butter over the top for a real treat!
Step-By-Step Instructions
Seriously, you can treat yourself to this wonderful and wholesome Oat Bar Recipe with one bowl and one pan.
1.) LINE YOUR PAN - In the first step, line your 8x8-inch pan with parchment paper. This makes it easy to get your oat bars out when they're done cooking. Now, preheat the oven to 350 degrees F (177 degrees C).
2.) COMBINE INGREDIENTS - Combine melted organic butter and honey (or sugar if using) in a large mixing bowl. Add eggs, baking soda, salt, and vanilla, mixing well. Add the oats and flour (dry ingredients) and mix until well combined. (Add any optional mix-ins. See recipe notes for suggestions.)
PRO TIP: spray your measuring cup with non-stick spray before putting your honey in - it will slide right out!
3.) BAKE - Press the easy oat bars into your lined baking dish. Finally, bake your bars in the oven for 20-25 minutes until the center is set and the outside is golden brown.
Your whole house should smell wonderful at this point!
Expert Tips & Tricks
- Oats: This recipe is best if you use old-fashioned oats, not instant oats. It will get too dense otherwise.
- Flour: We like using the healthy option of whole wheat flour, but regular flour or a combination of the two will also work.
- Sweetness: These bars aren't too sweet because you make them with honey, so bake them with brown sugar if you prefer a sweeter recipe.
- Thickness: Some readers prefer these baked oatmeal bars to be thinner. If you do, too, use a 9x9-inch square pan.
- Oil or Butter: Readers like to substitute ½ of the butter with coconut oil and have good results. We use organic butter, which gives the best flavor!
- More Moisture: If you prefer a moist bar, add ½ cup of unsweetened apple sauce to the wet ingredients.
Note: Every oven cooks differently. Your cooking time may vary.
Tips for Storing
To Freeze:
- Bake your bars as directed and allow your healthy oatmeal bars to cool completely.
- Cut into bars, then wrap individually in foil or plastic.
- Place wrapped bars in a freezer bag for later.
Thaw for at least one hour at room temperature before eating.
To Store: Layer the homemade bars between waxed paper in an airtight container. Store in the refrigerator for up to 5 days.
Bring back to room temperature before serving. You can wrap individual bars in plastic wrap for lunches.

Janet
I added butterscotch chips to the top of the batter before baking. These are really tasty and healthy too!
Erin
Awesome, Janet! What a great add-on to a delicious and nutritious bar!
Jenny
These look so good! What a great idea to make oatmeal bars, can't wait to try them. Thanks for sharing at Merry Monday!
Erin
Thanks for stopping by, Jenny! The wholesome ingredients make this a winning recipe any day of the week!
megan
I added abit of milk to the batter with chopped nuts and drizzled with melted nutella for a treat!!
Erin
Oh, my gosh! How lovely. I love your addition of Nutella!
Heather Naugler
I swapped out the honey and sugar for Almond Butter instead. Less sugar and more buttery goodness. Could also use Peanut Butter as well.
I found the recipe really dry and I only added 1 1/4 cups of flour. Not sure if it was because I added dried cranberries, organic pumpkin seeds and chia seeds. Next time I will add milk or water to make the mixture moist.
I make these in my mini bar ban so they are already to eat and enjoy in the perfect serving size.
Erin
I like your swaps, Heather, but the chia seeds could definitely have made these bars more dry as they soak up moisture. Also, cooking them in a mini bar pan can dry them out if you didn't decrease the cooking time.
Sana
Hi -are these chewy? I only like chewy ones. Also can I substitute rolled oats with steel cut oats?
Erin
They are definite on the softer side, so more chewy. I haven't tried using steel cut oats, so I don't know if that swap would work.
John Woodard
I made these last night (Brown Sugar variant). They're good, but I sometimes taste raw wheat flour that detracts from the overall experience. Where did I go wrong? I mixed it pretty thoroughly (by hand).
Erin
Hi John, Unless your whole wheat wasn't fresh (when it goes bad it has a stronger flavor), I don't know why you're tasting raw wheat. Sounds like you mixed it well.
Floyd
These oatmeal bars turned out very well and my wife loved them. Usually when i am looking for quick recipes i end up here, and the recipes are so well laid out that I can easily see where I can modify them to my liking. This recipe I did half butter and half coconut oil. I also left out the honey and used half a cup of xylitol instead. I plan to make them plenty more times abd will definitely add some fruit and nuts. Thanks again.
Liset
How long can I store in fridge for?
Erin
You can store these Oatmeal Bars for about 5 days in the fridge.

I am baking these rn, added a lil unsweetened Coco powder to AP flour and used BS instead of honey, also didn't have vanilla so added a touch of soy milk. Thought it would be a dry batter but seemed perfect hoping these turn out good to go along with my morning coffee
Erin
I hope they're delicious! You can definitely modify this recipe and it turns out well! Enjoy!
Danielle
Hi. I know this is an older post but I wanted to leave my review. This recipe is perfect. Simple, delicious not too sweet and easy to customize.
I made some changes to make it a bit healthier for a good breakfast. I substituted the butter with olive oil to reduce cholesterol. I substituted half of the flour with unflavored protein powder ( I use bariatric fusion powder). I also substituted the honey with maple syrup just for a different flavor.
The results:
A delicious oatmeal bar with 14 grams of protein per bar. It has the same amount of protein as a bar you buy at the store. It tastes way better, has no artificial sweeteners (most store bought bars are too sweet in my opinion) and it's super filling!
Thank you so much for the great recipe!
Erin
This is awesome, Danielle! I love your substitutions to make it a great bar for a protein fueled breakfast! Although this recipe is older, it's one of my top! People just love it! Enjoy and thanks for the review!
Staci
I just popped these in the oven. I added mashed banana, unsweetened coconut, chocolate chips and some flax seed. They smell yummy, ant wait to try them!
Erin
OMGosh! I LOVE hearing that! They sound amazing! And way to go with the flax seeds...always good to get a little more fiber in your diet!
Lianne
These are my favorite oatmeal bars! I add chocolate chips and chopped walnuts—they are delicious! I freeze them and they thaw out just perfect, I especially like to heat them and melt the chocolate a little! Thanks for the recipe!
Erin
Thank you, Lianne! You made my day 🙂 I love hearing that these bars are people's favorite! They are nutritious...and I agree, with the add ins, pretty incredible 🙂
kurt
im a student and will be using the recipe for an assessment

Erin
Good luck Kurt. This is a fairly simple recipe you should be able to do 🙂 Erin
Deb Auld
Hi,
Can the butter be substituted with either coconut oil or coconut butter? If so what would you recommend for amounts?
Thank you
Deb
Erin
I have had readers substitute the butter for coconut oil with good results, however, I've haven't tried it my self. The amount should remain the same. Thanks!
Crystal
I’m wondering if you could double in a 9x13 pan?? Would it still bake ok?
Erin
Good question. I think it would be close to working out okay, but they might come out a bit thick. However, I've never tried it to know for sure.
