How to Make Peanut Butter Chocolate Chip Bars
-
Preheat the oven to 350°F (175°C). Prepare an 8×8-inch baking pan by lining it with parchment paper, ensuring easy removal and clean-up later on.
-
Mix the creamy peanut butter, packed brown sugar, and granulated sugar in a large bowl using an electric mixer. Blend until smooth and creamy, then add the eggs one at a time, mixing well after each addition. Finally, stir in the vanilla extract for that lovely, warm flavor.
-
Whisk together the all-purpose flour and baking powder in a separate bowl. Gradually add this dry mixture to the peanut butter mixture, stirring gently until just combined; avoid overmixing to keep your bars nice and tender.
-
Fold in the semi-sweet chocolate chips. Make sure they are evenly distributed throughout the batter for those delightful melty pockets of chocolate in every bite.
-
Pour the batter into your prepared pan, spreading it evenly. Bake in the preheated oven for 25-30 minutes or until the top is golden brown and a toothpick inserted comes out clean with a few gooey chocolate bits attached.
-
Cool completely before slicing into squares. This helps the bars set perfectly and makes for easy handling when you’re ready to serve them.
Optional: Sprinkle a touch of sea salt on top before serving for a delightful flavor contrast.

Make Ahead Options
These Peanut Butter Chocolate Chip Bars are perfect for busy home cooks looking to save time without sacrificing flavor! You can prepare the batter up to 24 hours in advance; just mix all the ingredients and store it in an airtight container in the refrigerator. This keeps the flavors fresh and delicious until you’re ready to bake.

Freezer: To preserve the Peanut Butter Chocolate Chip Bars for up to 3 months, individually wrap each bar in plastic wrap and place them in a freezer-safe bag or container. Thaw in the fridge before enjoying.
Reheating: If you prefer your bars warm, simply microwave for about 10-15 seconds; this will rejuvenate the chocolate’s gooeyness while keeping the peanut butter delightful.

- To prevent overmixing, gently fold the dry ingredients into the wet mixture until just combined, preserving the tender texture.
- If you prefer a richer flavor, consider using dark chocolate chips instead of semi-sweet.
- Always keep an eye on your bars during the last few minutes of baking, as ovens can vary in temperature and you want them to be perfectly golden brown.
Peanut Butter Chocolate Chip Bars Recipe FAQs
How do I know if my peanut butter is fresh enough?
Absolutely! To ensure your peanut butter is fresh, check for a smooth consistency and a pleasant nutty aroma. If you see dark spots or if it smells rancid, consider getting a fresh jar!
How should I store leftover Peanut Butter Chocolate Chip Bars?
You can store the bars in an airtight container at room temperature for up to 3 days. This method keeps the bars soft and chewy. If you want to extend their freshness, keep them in the refrigerator for up to a week, but allow them to come back to room temperature before enjoying to really savor that delightful taste.
Can I freeze these bars? If so, how?
Very! To freeze your Peanut Butter Chocolate Chip Bars, wrap each cooling bar individually in plastic wrap and place them in a freezer-safe bag or airtight container. They can stay fresh for up to 3 months. When you’re ready to enjoy, simply thaw in the fridge overnight or at room temperature for a few hours. For a warm treat, microwave for 10-15 seconds for that delicious gooeyness!
What should I do if my bars turn out too dry?
If your bars come out dry, it may be a result of overbaking or not enough moisture from the peanut butter. To troubleshoot for next time, keep an eye on them during the last few minutes of baking, and perhaps add a bit more peanut butter for extra moisture. Always test with a toothpick—aim for a few gooey chocolate bits, not completely clean!
Are these bars safe for people with nut allergies?
Not at all! Since peanut butter is the main ingredient, these bars are not suitable for individuals with peanut allergies. However, you could experiment with sunbutter or other nut-free alternatives to create a safe version if you’re baking for someone with allergies. Just keep in mind that flavor and texture might vary slightly.
Can I use natural peanut butter instead of creamy peanut butter?
Very much! Natural peanut butter will work, but it may result in a slightly different texture. Be sure to stir it well before measuring since natural varieties can separate. Enjoy the unique flavor, but anticipate a slightly denser bar.
