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.

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 like to also fold through some chocolate chips because why not?

Step 1- Make the bar batter. In a large bowl, combine all of the dry and wet ingredients. Stir in mix-ins, if using them.

Step 2- Bake. 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 boost of protein and staying power.
- Experiment with mix-ins. Fold in sunflower seeds, dried cranberries, cherries, or chopped walnuts.
- Enhance the flavor of the bars. Add cinnamon or one teaspoon of vanilla extract.
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
