Step-by-step Preparation of Peanut Butter Banana Oatmeal Bars
Creating peanut butter banana oatmeal bars is not just about the delicious end result; it’s about enjoying the process! Let’s walk you through each step to ensure your bars turn out perfect every time.
Prepping your workspace and ingredients
Start by organizing your cooking area! Preheating your oven to 350℉ (180℃) sets you up for success. As it warms, prepare your 9x13 inch baking pan. Grease it gently on the bottom and sides for easy release later. Pro tip: line the pan with parchment paper, leaving an overhang on two sides. This clever trick will make pulling the bars out a breeze!
Next, gather your ingredients. Having everything measured and ready to go not only streamlines the process but also keeps you focused. You’ll need:
- ¼ cup of oil or melted butter
- 2 eggs (room temperature)
- 1 cup of mashed bananas
- ⅔ cup of creamy peanut butter
- and more!

Mixing the dry ingredients
In a large bowl, combine the dry ingredients. This is where you’ll blend together:
- ½ cup all-purpose flour
- 2 cups rolled oats
- ¾ teaspoon baking powder
- ½ teaspoon baking soda
- 1 teaspoon cornstarch
- 1 ½ tsps cinnamon
- ¼ teaspoon salt
Mix these thoroughly for an even distribution of flavors.
Whisking the wet ingredients
Now, let’s head to another bowl for the wet ingredients. In here, whisk together:
- ¼ cup of oil or melted butter,
- ¾ cup dark brown sugar,
- ⅔ cup creamy peanut butter.
Blend until it’s a gorgeous cohesive mixture. Next, add in the eggs, bananas, milk, and vanilla. Whisk until it’s all combined and smooth. The aroma is already tantalizing!
Combining dry and wet ingredients
Time to bring it all together! Carefully fold the dry ingredients into the wet mixture until just combined; remember, don’t over-mix! This crucial step keeps your bars fluffy instead of dense.
Spreading the batter and adding the topping
Pour the batter into your prepared pan, spreading it evenly. To elevate the flavor, combine 2 tablespoon white sugar with ¼ teaspoon cinnamon in a small cup. Sprinkle it over the top for a deliciously sweet crunch!
Baking to perfection
Slide your pan into the oven, and set your timer for 45-55 minutes. You'll know the bars are ready when a toothpick inserted into the center comes out clean. Remember to let them cool completely in the pan before slicing.
These peanut butter banana oatmeal bars are not only great for snacking but can also be your go-to breakfast or quick energy boost! Store them in an airtight container, and enjoy throughout your week!

Variations on Peanut Butter Banana Oatmeal Bars
Chocolate Chip Oatmeal Bars
If you're a fan of a sweet twist, try adding chocolate chips to your peanut butter banana oatmeal bars! Just fold in a cup of semi-sweet chocolate chips into the batter before baking. This creates a delightful melty texture that pairs beautifully with the banana and peanut butter flavors. You could even experiment with dark chocolate or white chocolate chips for a different kind of indulgence.
Nut-Free Options
No nuts? No problem! For a nut-free variation, simply replace peanut butter with sunflower seed butter or soy nut butter. These alternatives provide a similar creamy texture and flavor without the allergens. Be sure to check labels for any hidden nuts in ingredients like granola or chocolate chips if you're creating a completely nut-free bar.

Cooking Tips and Notes for Peanut Butter Banana Oatmeal Bars
Common Mistakes to Avoid
When whipping up your peanut butter banana oatmeal bars, a few pitfalls can easily derail your baking success:
-
Overmixing the Batter: Once you combine the wet and dry ingredients, stir just until they’re blended. Overmixing can lead to tough bars instead of the desired chewy texture.
-
Ignoring Egg Temperature: Using eggs straight from the fridge can cause the batter to chill, affecting texture. Always use room temperature eggs for the best results.
-
Not Measuring Precisely: Baking is a science, so ensure you’re accurately measuring ingredients, especially flour and oats. A kitchen scale can be a game-changer here.
-
Underbaking: Every oven is different, so keep an eye on your bars. If the toothpick comes out wet, continue baking but check every few minutes to prevent drying them out.
