Step-by-Step Instructions
Step 1: Preheat the Oven and Prepare the Baking Dish
Preheat your oven to 350°F (175°C). Line a 9×9-inch square baking dish (or similar size) with parchment paper or lightly grease it to ensure the bars come out easily. You can also use an 8×8-inch dish if you want thicker bars.

Step 2: Mix Dry Ingredients
In a large mixing bowl, combine the dry ingredients:
- Rolled oats
- Baking soda
- Cinnamon
- Salt
- Whole wheat flour
- Ground flaxseed (if using)
Stir everything together until evenly mixed.
Step 3: Mix Wet Ingredients
In a separate bowl, whisk together the wet ingredients:
- Peanut butter (If it’s too thick, warm it slightly in the microwave or over low heat to make it easier to mix.)
- Maple syrup or honey
- Applesauce
- Egg
- Vanilla extract
Whisk the wet ingredients until smooth and well-combined. The peanut butter should be creamy and fully incorporated with the other ingredients.
Step 4: Combine Wet and Dry Ingredients
Pour the wet ingredients into the dry ingredients. Stir everything together with a wooden spoon or spatula until fully combined. The mixture should be thick and slightly sticky, but it should hold together well.
Step 5: Add Optional Add-ins
If you’re using any optional add-ins, like chocolate chips, dried fruit, or nuts, fold them into the batter at this stage.
Step 6: Press the Mixture into the Pan
Transfer the cookie dough mixture into the prepared baking dish. Use a spatula or your hands to press the mixture down evenly, making sure it fills the dish to the edges and is smooth on top.
Step 7: Bake
Place the dish in the preheated oven and bake for 18-22 minutes. The bars are done when they’re golden brown around the edges and a toothpick inserted in the center comes out clean (or with just a few crumbs). Keep an eye on the bars towards the end of the baking time to ensure they don’t overcook.
Step 8: Cool and Slice
Let the bars cool in the pan for about 10 minutes before transferring them to a wire rack to cool completely. Once they’ve cooled, slice them into squares or bars. You should get about 12-16 bars, depending on how large you cut them.
Pro Tips for Perfect Peanut Butter Oatmeal Cookie Bars
1. Measure Your Ingredients Properly
Accurate measurements are key to getting the perfect texture in your cookie bars. For the oats, flour, and peanut butter, be sure to measure them carefully to avoid over or under-mixing.
2. Use Natural Peanut Butter
For the healthiest option, choose natural peanut butter without added sugars, hydrogenated oils, or preservatives. This gives you the cleanest, most nutritious result.
3. Don’t Overmix
When combining the wet and dry ingredients, mix just until everything is incorporated. Overmixing can cause the bars to be too dense or chewy.
4. Experiment with the Texture
If you like your bars chewier, bake them for a shorter time. If you prefer a firmer, crispier texture, bake them a little longer until the edges are more golden and crisp.
5. Let Them Cool
The bars will firm up as they cool, so avoid cutting them immediately after baking. Let them cool in the pan for at least 10 minutes before slicing.
Flavor Variations
There are many ways to put your own twist on these healthy peanut butter oatmeal cookie bars. Here are some fun variations to try:
1. Chocolate Peanut Butter Oatmeal Bars
- Add 1/4 cup dark chocolate chips into the batter for a rich, indulgent chocolate flavor. The peanut butter and chocolate combination is a timeless classic!
2. Coconut Peanut Butter Oatmeal Bars
- Mix in 1/4 cup unsweetened shredded coconut for a tropical twist. The coconut adds a chewy texture and pairs wonderfully with the peanut butter.
3. Banana Peanut Butter Oatmeal Bars
- Replace the applesauce with mashed banana for a naturally sweet flavor and extra moisture. Bananas also add potassium, making these bars even more nutritious.
4. Apple Cinnamon Oatmeal Bars
- Add 1/2 cup of diced apples (preferably peeled) and an extra sprinkle of cinnamon for a fall-inspired flavor. The apples will provide a juicy burst and enhance the texture of the bars.
5. Nutty Peanut Butter Oatmeal Bars
- Stir in 1/4 cup chopped nuts (almonds, walnuts, or cashews) for added crunch and healthy fats. These nuts also add a nice contrast to the chewy oats and peanut butter.
Healthy Substitutions
Want to make your Peanut Butter Oatmeal Cookie Bars even healthier? Here are some easy substitutions you can make:
1. Sweeteners
- Instead of maple syrup or honey, you can use stevia or monk fruit sweetener for a lower-carb version. Just adjust the amount based on the sweetness level of the substitute.
2. Oats
- Use gluten-free oats if you need a gluten-free option. These oats are processed in a gluten-free facility and are safe for those with gluten sensitivities.
3. Flour
- Swap the whole wheat flour with almond flour or coconut flour for a gluten-free option. Note that if you use coconut flour, you may need to adjust the liquid slightly, as it absorbs more moisture.
4. Peanut Butter
- If you’re allergic to peanuts or prefer a different flavor, try using almond butter, cashew butter, or sunflower seed butter. These butters provide similar consistency and taste but with their own unique flavor profiles.

Frequently Asked Questions
Can I make these bars vegan?
Yes! Simply swap the egg for a flax egg (1 tablespoon flaxseed meal + 3 tablespoons water) or chia egg (1 tablespoon chia seeds + 3 tablespoons water). You can also use maple syrup or agave instead of honey.
Can I use quick oats instead of rolled oats?
Yes, but the texture will be slightly different. Quick oats absorb more moisture, so your bars may be a little softer or denser.

Absolutely! You can double the ingredients and bake them in a larger pan. Just keep in mind that you may need to increase the baking time slightly.
