These oatmeal breakfast bars are incredibly simple to prepare and require only five wholesome ingredients. Thick, soft, and chewy, they’re studded with chocolate chips for a touch of indulgence while remaining flourless, eggless, and butterless. They make an ideal grab-and-go breakfast, a satisfying snack, or a portable treat for mornings when time is tight.
These bars are a family favorite and perfect for busy households. They bake quickly and fill the kitchen with the comforting aroma of oats and banana. Because they rely on mashed ripe bananas and a natural sweetener, they offer a more wholesome option than many store-bought bars. You can prepare them ahead of time for the week, slice and store them in the fridge, or freeze individual portions for longer storage.
Ingredients for oatmeal breakfast bars
- Old fashioned rolled oats: Use rolled oats for the best chewy texture and a hearty, whole-grain base.
- Ripe bananas: Overripe bananas mashed until smooth add natural sweetness and moisture, replacing eggs and butter.
- Peanut butter: Creamy peanut butter binds the mixture and adds protein and healthy fats. Any creamy nut or seed butter will work.
- Maple syrup: Adds sweetness and a subtle flavor. Honey or agave can be used instead if preferred.
- Chocolate chips: Semi-sweet or dark chocolate chips add a pleasant contrast; dried fruit or chopped nuts are good alternatives.
How to make oatmeal breakfast bars
- Preheat the oven to 350°F (175°C). Line an 8 x 8 inch baking pan with parchment paper for easy removal and cleaner slicing.
- In a medium-large mixing bowl, combine the rolled oats, mashed ripe bananas, creamy peanut butter, maple syrup, and chocolate chips.
- Stir thoroughly until all ingredients are evenly combined and the mixture holds together. If it seems too dry, add a splash of milk or a little more maple syrup; if too wet, add a few tablespoons of oats.
- Transfer the mixture to the prepared pan and press it down evenly with the back of a spoon or a spatula. Sprinkle a few extra chocolate chips on top if you like.
- Bake for 14–15 minutes, or until the edges begin to turn golden brown. Avoid overbaking to keep the bars soft and chewy.
- Remove from the oven and allow to cool in the pan for about 10 minutes. Lift the parchment to remove the slab, then slice into 12 bars once slightly cooled. Serve warm or at room temperature.
Ingredient substitutions and variations
- Oats: Quick oats can be used in a pinch, but they produce a softer, less chewy bar. For a mix of textures, try half rolled oats and half quick oats.
- Bananas: Unsweetened applesauce or pumpkin puree can substitute for banana if you need a different flavor profile; these may be less sweet, so consider adding a touch more maple syrup.
- Nut butter: Swap peanut butter for almond, cashew, or sunflower seed butter to accommodate allergies or preferences.
- Sweeteners: Honey, agave, or brown rice syrup are all suitable alternatives to maple syrup.
- Add-ins: Stir in chopped nuts, shredded coconut, dried fruit, seeds (such as chia or flax), or a pinch of cinnamon for extra flavor and texture.
Storage and reheating
Store the baked bars in an airtight container in the refrigerator for up to five days. They’re great cold straight from the fridge or warmed for 20–30 seconds in the microwave if you prefer them soft and gooey. For longer storage, wrap individual bars and freeze them for up to three months. Thaw overnight in the refrigerator or heat briefly before serving.
Serving suggestions and tips
These oatmeal bars are versatile: enjoy them plain, spread with a thin layer of nut butter, or topped with yogurt and fresh fruit for a more substantial breakfast. To keep bars intact while slicing, chill them briefly in the fridge after cooling to room temperature. For even baking, press the mixture firmly and spread it to an even thickness in the pan. If you prefer a chewier center, reduce baking time slightly; for a firmer bar, bake an extra 1–2 minutes.
