Oatmeal Breakfast Bars
Ingredients for easy oatmeal bars:
- Rolled Oats– Rolled oats are what gives this recipe it’s classic oatmeal flavor.
- All Purpose Flour– Also referred to as white flour.
- Baking Soda– A leavening agent that helps give lift to your baked good.
- Baking Powder– Also a leavening agent.
- Salt– Salt is added to recipes as a flavor enhancer.
- Cinnamon– Cinnamon is key to giving this that classic flavor.
- Brown Sugar– Adds a slight rich molasses flavor to your bars.
- Vanilla Extract– Use pure vanilla extract and not imitation.
- Milk– We make this with regular 2% milk, however we have also used coconut and almond milk with success.
- Eggs– Large eggs at room temperature work best.
- Vanilla frosting– I recommend using this recipe, but any vanilla frosting will do.
Difference between quick oats and rolled oats:
Rolled oats tend to be thicker than quick cut oats. This makes them perfect for creating granola bars. I have used both in this recipe. We prefer keeping it to rolled oats. This gives you a sturdy bar that tastes incredible.
Optional mix-in ideas for oatmeal:
We like this recipe as written, but you could also add in some of your favorite oatmeal mix-in’s. Some of our favorite ideas are listed below for you to consider.
- Toasted Diced Nuts
- Coconut

Comments & Reviews
Nicole says
part of the recipe says oat flour, but then it is not in ingredient list. So, yes or no to oat flour?
Aqsa says
Are these soft baked?
Kailin says
Is there a way to freeze these so they last longer? Thank you! Can’t wait to try.
Jesseca says
Hi Kailin. Yes, you can freeze these. I place mine in a large freezer bag after they have cooled completely and freeze for up to 3 months.
Kailin says
Thank you! They turned out with a sticky texture. Is this normal? I used almond milk.
Jesseca says
It’s possible there was a little too much milk added in. You should still be ok to freeze them. I’ll add this on my list to test with almond milk this week and report back to you
Kailin says
Thank you so much!
Gwen says
Just made this tonight and it’s cooling now. Can’t wait to have it tomorrow morning. Question do you store this in the fridge?
Jesseca says
Hi Gwen, I would store this in either a ziptop bag or in an airtight container inside the refrigerator. It should keep for up to five days.
Kailin says
Thank you! They turned out with a sticky texture. Is this normal? I used almond milk.

Kelsey says
Do you have your vanilla frosting recipe?
Jesseca says
I haven’t posted my favorite version yet, but here is a quick breakdown: 1/2 cup butter, 1-/2 cups powdered sugar, 1-2 tablespoon heavy cream, 1/2 teaspoon vanilla
Whisk the butter and powdered sugar until combined. Add cream and vanilla and whip 5 minutes, or until light and fluffy.
Kristopher says
The kids have just gone back to school, and they’ve been saying they get hungry during the day, so I’ve been looking for a good bar recipe I could send with them. This worked out fantastic! There are some changes I made to fit their dietary needs (like using almond milk and quick oats instead), and this recipe is a great base for alterations with fruits and add-ins, so I can see this being a favorite for a good while. Thanks for the delicious recipe!
Jesseca says
This makes me so happy to hear! It’s a go-to for back to school for us. My teenager loves to keep these on hand for breakfast or packed lunch.
Nina says
I’m making these today! Does the recipe have oat flour and AP flour? I see in the instructions is saysit but not in the ingredient list.
Jesseca says
Hi Nina, Sorry about that! I used to include oat flour, but have since removed it and found that these bars are perfect without. Just forgot to remove that from the instructions. Fixed. 🙂
Martha says
Hi Jessica, I want to make these but I’m confused. The ingredient list doesn’t match the instructions. there is no oat flour in the ingredient list. Please help. Thanks.
Jesseca says
Hi Martha, so sorry about that! I originally had oat flour in the recipe but have since removed it. I’ll fix that for you.
Frances says
I noticed that also and didn’t know what to do. Thanks for getting us an answer
