- Semi-sweet chocolate chips: Little bursts of melty chocolate in each bite.

How to Make Peanut Butter Oatmeal Bars Recipe
Step 1: Prepare Your Pan and Oven
Start by preheating your oven to 350 degrees Fahrenheit to get it nice and ready. Then, line a 9×9 inch baking dish with parchment paper or give it a good spray with cooking spray. This simple step ensures your bars won’t stick and will come out cleanly after baking.
Step 2: Mix the Dry Ingredients
Grab a large mixing bowl and whisk together the oatmeal chocolate chip cookie mix, rolled oats, and semi-sweet chocolate chips. Combining these dry ingredients first helps evenly distribute the oats and chocolate so every bar has a balanced flavor and texture.
Step 3: Add Wet Ingredients to Form Dough
Next, use a stand or hand mixer to beat in the eggs, peanut butter, and heavy cream. This step transforms your dry mixture into a thick and luscious dough that’s the foundation of your bars. Be sure to mix well so everything is combined smoothly.
Step 4: Spread the Dough Evenly
Transfer your thick dough to the prepared baking dish and press it down evenly into a solid, thick layer. This is what gives your bars a perfect structure and helps them bake uniformly throughout.
Step 5: Bake Until Golden and Set
Slide your baking dish into the oven and bake for 25 to 35 minutes. You’ll know they’re ready when the edges turn a lovely golden brown and the bars feel set to the touch. The aroma filling your kitchen at this stage is pure bliss.
Step 6: Cool and Cut
Allow the bars to cool completely in the pan before slicing into squares. This is crucial because it lets them firm up so you get clean cuts and perfect bite-sized portions ready to enjoy.
How to Serve Peanut Butter Oatmeal Bars Recipe

Garnishes
While these bars are fantastic on their own, feel free to sprinkle a few extra chocolate chips or a drizzle of melted peanut butter on top just before serving for an added touch of indulgence. A light dusting of powdered sugar can also make them look as good as they taste.
Side Dishes
Serve these bars alongside a cup of cold milk or a warm mug of coffee or tea. Their hearty, nutty flavor complements both beverages wonderfully, creating a snack moment that’s both satisfying and comforting.
Creative Ways to Present
If you want to impress friends or family, present the bars stacked on a pretty plate with a small bowl of whipped cream or vanilla ice cream on the side. You can also wrap individual bars in parchment paper tied with a ribbon for lovely homemade gifts.
Make Ahead and Storage
Storing Leftovers
Keep any leftover bars in an airtight container at room temperature for up to 3 days. This short-term storage keeps them moist and fresh without drying out, so they’re ready to grab whenever the craving hits.
Freezing
For longer storage, these bars freeze beautifully. Wrap them individually or in slices with plastic wrap, then place in a freezer-safe container or bag. They’ll hold up well for up to 3 months, perfect for planning ahead.
Reheating
When you’re ready to enjoy frozen bars, simply let them thaw at room temperature or warm them briefly in the microwave for about 15-20 seconds. This softens them just enough to recapture that fresh-baked feeling without melting the chocolate too much.
FAQs
Can I use crunchy peanut butter instead of creamy?
Absolutely! Using crunchy peanut butter will add a delightful texture to the bars, giving each bite a nice little nutty crunch. Just be aware it might make the dough a little thicker, but it will still bake beautifully.
Is it possible to make these bars gluten-free?
To make a gluten-free version, make sure to use a gluten-free oatmeal chocolate chip cookie mix and certified gluten-free rolled oats. This way, you can still enjoy the same tasty bars without any gluten concerns.
Can I substitute the heavy cream for something else?
If you don’t have heavy cream on hand, you can substitute with whole milk or even a non-dairy milk like coconut milk, though the bars might be slightly less rich. For the best texture, heavy cream is recommended.
How long do these bars last once baked?
When stored properly in an airtight container at room temperature, these Peanut Butter Oatmeal Bars stay fresh and delicious for about 3 days. Beyond that, they’re best stored in the fridge or freezer to maintain quality.
Can I add nuts or dried fruit to this recipe?
Definitely! Chopped nuts like walnuts or pecans, or dried fruit such as raisins or cranberries, can add wonderful flavors and textures. Just fold them into the dough along with the chocolate chips for a personal twist on this classic Peanut Butter Oatmeal Bars Recipe.
