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.

baked oatmeal bars
It didn’t seem like enough batter to put in a 9×13 , so I used an 8 x 8; it wasn’t sweet enough for me, although it had a cup of brown sugar ( I didn’t pack the brown sugar before I put it in though). Anyhow, I cooked it 15 minutes longer since it was an 8 x 8 pan instead of the 9 x 13. It was ok.
part of the recipe says oat flour, but then it is not in ingredient list. So, yes or no to oat flour?
Are these soft baked?
Is there a way to freeze these so they last longer? Thank you! Can’t wait to try.
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.
Thank you! They turned out with a sticky texture. Is this normal? I used almond milk.
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
Thank you so much!
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?
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.
Thank you! They turned out with a sticky texture. Is this normal? I used almond milk.
I don’t see oat flour.in the ingredients list. please clarify
never mind I found the answer down below. I’ll be making these tomorrow!
Do you have your vanilla frosting recipe?
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.
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!
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.
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.
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. 🙂
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.
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.
I noticed that also and didn’t know what to do. Thanks for getting us an answer
