Recommended Tools
To create your Healthy Peanut Butter Oatmeal Cookie Bars, you will need a few essential kitchen tools:
- Mixing bowl: For combining all your ingredients.
- Whisk: To beat the eggs and mix everything smoothly.

Step-by-Step: Healthy Peanut Butter Oatmeal Cookie Bars

Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). This ensures that your bars bake evenly and come out perfectly golden brown.
Step 2: Prepare the Baking Pan
Grease your baking pan or line it with parchment paper for easy removal after baking.
Step 3: Mix the Wet Ingredients
In a mixing bowl, add the 2 eggs, 1 cup of peanut butter, ½ cup of pure maple syrup, and the optional 1 teaspoon of vanilla extract. Whisk everything together until smooth and well combined.
Step 4: Add the Dry Ingredients
To the wet mixture, add 1 cup of rolled oats, 1 teaspoon of baking soda, the optional ½ teaspoon of ground cinnamon, and ½ teaspoon of sea salt. Stir until everything is fully incorporated.
Step 5: Fold in Chocolate Chips
If you’re using chocolate chips, fold in 1 cup at this point. They add a delightful sweetness and melty goodness to your bars.
Step 6: Bake
Pour the batter into your prepared baking pan, spreading it evenly. Bake in the preheated oven for about 20-25 minutes, or until the edges are golden and a toothpick inserted into the center comes out clean.
Step 7: Cool and Slice
Once baked, remove the pan from the oven and let the bars cool in the pan for at least 10-15 minutes. Then, lift them out (if using parchment paper) and slice into squares or bars.
Vegan & Vegetarian Swaps

If you’re looking to make these Healthy Peanut Butter Oatmeal Cookie Bars vegan, consider the following swaps:
- Replace eggs with ½ cup of unsweetened applesauce or 2 flax eggs (2 tablespoons of flaxseed meal mixed with 6 tablespoons of water, let sit until thickened).
- Ensure your chocolate chips are dairy-free if desired.
Missteps & Fixes
Even the best bakers can make mistakes! Here are some common missteps and how to fix them:
- If the bars are too crumbly, it could be due to too much oats or not enough binding ingredients. Add a bit more peanut butter or a splash of non-dairy milk to moisten the mixture.
- For overly dry bars, ensure you’re measuring your ingredients correctly. Too much oat flour can dry out your bars. Stick to the 1 cup of rolled oats.
- If they don’t rise well, check that your baking soda is fresh. Expired baking soda can cause baked goods to not rise properly.
Freezer-Friendly Notes
These Healthy Peanut Butter Oatmeal Cookie Bars are great for meal prep and freezing!
- Cool the bars completely before slicing and wrapping.
- Wrap them tightly in plastic wrap or aluminum foil, and then place them in an airtight container or freezer bag.
- They can be frozen for up to 3 months. Thaw them in the fridge overnight for a quick snack or breakfast option.
