Step‑by‑Step Instructions for Peanut Butter Oatmeal Breakfast Bars
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This will ensure that the Peanut Butter Oatmeal Breakfast Bars bake evenly. While the oven warms up, gather your baking dish and prepare it by either lining it with parchment paper or greasing it generously.
Step 2: Mix Wet Ingredients
In a large mixing bowl, combine the mashed bananas and vegetable oil. Use a fork or whisk to mix them together until they’re well blended and creamy. This should take about 1-2 minutes. The bananas should be super ripe, adding natural sweetness and moisture to your bars.
Step 3: Add Sugar and Eggs
Once the banana and oil mixture is smooth, add in the brown sugar. Mix thoroughly for another 1-2 minutes until fully combined. Next, crack in the egg and pour in the vanilla extract and salt. Continue mixing until everything is harmonious, with a thick batter forming.
Step 4: Incorporate Dry Ingredients
Now it’s time to add the baking soda, all-purpose flour, and rolled oats to your wet mixture. Gently fold these dry ingredients in using a spatula to avoid overmixing. You want to combine them until just incorporated, leaving a few streaks of flour visible for the best texture in your Peanut Butter Oatmeal Breakfast Bars.
Step 5: Fold in Chocolate Chips
With the batter nicely mixed, carefully fold in the milk chocolate chips. This adds a delightful sweetness and richness to your bars. Be sure to distribute the chocolate evenly throughout the mixture, ensuring each bite has a piece of chocolatey goodness.
Step 6: Spread into Baking Dish
Transfer the mixture into your prepared baking dish, spreading it out evenly with a spatula. Ensure the batter reaches all corners of the dish as this will allow for uniformly sized bars once baked. Press it down gently to ensure it holds together well while baking.
Step 7: Bake the Bars
Place the baking dish in the preheated oven and bake for 18-22 minutes. Keep an eye on them; they are ready when a toothpick inserted into the center comes out clean. The top should be lightly golden and firm to the touch, signaling that your Peanut Butter Oatmeal Breakfast Bars are perfectly cooked.
Step 8: Cool and Drizzle
Once baked, remove the dish from the oven and let cool for about 10 minutes. After cooling, transfer the bars to a wire rack to cool completely. Meanwhile, melt some peanut butter in the microwave for about 30 seconds until it’s pourable, then drizzle it over the cooled bars for an extra layer of flavor.
Step 9: Slice and Serve
Once your Peanut Butter Oatmeal Breakfast Bars are fully cooled, slice them into squares or rectangles as per your preference. These bars can be enjoyed immediately or stored in an airtight container for a quick, healthy snack or breakfast option for the family!

How to Store and Freeze Peanut Butter Oatmeal Breakfast Bars
Fridge: Store the bars in an airtight container in the refrigerator for up to 5 days. This keeps them fresh and ready for quick snacking!

Thawing: To enjoy, thaw them in the fridge overnight or in the microwave for a quick snack. Just ensure they’re covered to prevent drying out.
Reheating: If enjoyed warm, pop them in the microwave for about 15-20 seconds. This revives their softness and peanut butter flavor, making them even more delicious!

Peanut Butter Oatmeal Breakfast Bars Recipe FAQs
What type of bananas should I use for the recipe?
Absolutely! Use super ripe bananas, as they provide the best flavor and sweetness. Look for bananas with brown spots; they’ll be softer and mash easily, blending beautifully into your batter.
How long can I store the bars in the refrigerator?
You can store your Peanut Butter Oatmeal Breakfast Bars in an airtight container in the refrigerator for up to 5 days. This keeps them fresh, allowing for easy grab-and-go options for busy mornings or snacks whenever you need them.
Can I freeze the bars, and how should I do it?
Very easy! To freeze your bars, wrap each one individually in plastic wrap and then place them in an airtight container or freezer bag. They can last up to 3 months in the freezer. When you’re ready to enjoy, simply thaw them in the fridge overnight or microwave them for a quick snack—just ensure they’re covered to prevent them from drying out.
What should I do if the bars are too crumbly when cutting?
I recommend allowing the bars to cool completely before cutting them. If they are still crumbly, try reducing your baking time by a couple of minutes next time or adding a tiny bit more moisture, like an additional banana or a splash of milk, to help bind the ingredients better.
Are there any dietary considerations for these bars?
Certainly! If you or someone has nut allergies, you can substitute peanut butter with sunbutter or a seed-based alternative. Additionally, for vegan options, just replace the egg with a flax egg, which you can make by mixing one tablespoon of ground flaxseed with three tablespoons of water and letting it sit for about 5 minutes until it gels. Enjoy making these Peanut Butter Oatmeal Breakfast Bars safe for everyone!
Can I customize the ingredients for personal preferences?
The more the merrier! You can absolutely customize these bars. Feel free to swap the peanut butter for almond butter, include dried fruits like cranberries or raisins, or even use different types of chocolate chips.
