How to Make Peanut Butter Oatmeal Bars Recipe
Step 1: Prepare Your Pan
Start by lining an 8×8-inch baking dish with parchment paper. This simple step ensures your bars will lift out easily once they’re set, making clean-up a breeze and keeping everything intact when you slice.
Step 2: Mix the Wet Ingredients
In a large bowl, whisk together the creamy peanut butter, honey (or maple syrup), melted coconut oil, and vanilla extract until you have a smooth, velvety mixture. This blend creates the flavorful base that holds your bars together.
Step 3: Add the Dry Ingredients
Gently stir in the rolled oats and salt until everything is well combined. The oats give the bars their satisfying chew, and the salt highlights each ingredient’s natural flavors perfectly.
Step 4: Fold in the Extras
If you’re using mini chocolate chips, fold them in carefully now. These add a lovely surprise of sweetness and texture without overpowering the wholesome oats and peanut butter.
Step 5: Press the Mixture Into the Pan
Firmly press the mixture into your prepared dish, smoothing out the top with the back of a spoon or your hands. This ensures the bars hold together well once chilled and makes slicing easier.
Step 6: Chill Until Set
Pop the pan into the refrigerator for at least one hour. This chilling time is essential to firm up the bars so they hold their shape and are ready to enjoy.
Step 7: Slice and Serve
Once set, lift the slab out using the parchment paper and cut it into 12 bars. Now your Peanut Butter Oatmeal Bars Recipe is ready to be shared and savored!

FAQs
Can I use crunchy peanut butter instead of creamy?
