My oatmeal breakfast bars are chewy, soft, and the healthy way to start your morning. Made with three ingredients, they bake in just 15 minutes!
If I know I have a hectic week or a bunch of early morning meetings lined up, I make my oatmeal bars.
They store like a dream and taste fresh all week long. Plus, the added fiber and healthy fats leave me feeling like I got a real breakfast and keep me from getting hangry before lunch. I usually make these bars on Sunday evenings. That way, they’re ready to grab and go the rest of the week.

★★★★★ REVIEW
“I was serving these bars for our dessert, and my husband, grandson, and I loved them!! I need more recipes like this one, so easy! Thanks so much!” – Donna
Ingredients needed
- Rolled oats AND/OR oat flour. Adds a chewy and hearty texture while also being high in fiber and protein. Quick oats will work, but they won’t be as dense. I like to use a mix of rolled oats and oat flour for a softer more uniform texture.
- Bananas. Adds sweetness and moisture to the bars. The browner the bananas the sweeter the bars will be.
- Peanut butter. Smooth and drippy with no added sugar or salt. You can swap this out for almond butter, cashew butter, or a nut-free alternative like sunflower seed butter.
- Optional mix-ins. Maple syrup or honey for added sweetness. I also like to fold in some chocolate chips because why not?
How to make oatmeal breakfast bars
This is an overview with step-by-step photos. Full ingredients & instructions are in the recipe card below.
Step 1– Combine all of the dry and wet ingredients in a large bowl. Stir in mix-ins, if using them.
Step 2- Transfer the mixture to the lined pan and bake for 15 minutes or until the top is firm. Let them cool in the pan completely before slicing and serving.
Arman’s recipe tips
- Swap the mashed banana. If you’d rather not use bananas, use equal portions of unsweetened applesauce or pumpkin puree. If you make this swap, you’ll want to add some honey or maple syrup to make up for the sweetness.
- Make them gluten-free by using gluten-free oats.
- Add protein. Add 1/4 cup (34 grams) of your favorite protein powder to the batter for an extra protein boost and staying power.
- Add mix-ins. Fold in sunflower seeds, dried cranberries, cherries, or chopped walnuts. Cinnamon and vanilla are also delicious.
Storage instructions
To store: Leftover bars should be stored in an airtight container at room temperature for up to two days or in the refrigerator for up to one week.
To freeze: Place the cooled bars in a freezer-safe container and freeze for up to six months.
Frequently asked questions
Yes! Swap out the oats for equal parts quinoa flakes or buckwheat flakes. I found these have an almost identical texture to the rolled oats.
