Sometimes you just need a dessert that works. No fuss, no chilling dough, no scooping a million little cookies. This is that recipe. I’m going to show you how to make the chewiest, gooiest peanut butter chocolate chip cookie bars you’ve ever had, and it’s so easy you’ll wonder why you ever bothered with regular cookies.
These bars are my secret weapon for potlucks, last-minute bake sales, or just a Tuesday night when you need something sweet. They come together in one bowl and taste like a warm hug. Trust me, you can do this.
What You’ll Need
Getting your ingredients ready first makes everything go so much smoother. It’s a little thing my grandma taught me, and it saves you from frantically searching for the baking soda while your butter and sugar get weird.
Here’s the breakdown of everything you need to grab from the pantry. I have some specific thoughts on a few of these, so don’t just skim past it.
| Ingredient | Amount |
|---|---|
| All-Purpose Flour | 2 ½ cups |
| Baking Soda | 1 teaspoon |
| Salt | ½ teaspoon |
| Unsalted Butter | 1 cup (2 sticks) |
| Light Brown Sugar | 1 cup, packed |
| Granulated Sugar | ½ cup |
| Creamy Peanut Butter | 1 cup |
| Large Eggs | 2 |
| Vanilla Extract | 2 teaspoons |
| Semi-Sweet Chocolate Chips | 1 ½ cups |
A quick note on a couple of key players here. For the butter, make sure it’s softened to room temperature. Just leave it on the counter for an hour or so. If it’s melted, your bars will spread too much and get greasy. Cold butter won’t cream properly. Room temp is the magic spot.
For the peanut butter, use the regular creamy kind like Jif or Skippy. The natural stuff that you have to stir can separate and make the bars oily. Save that for your toast.
The Tools for the Job
You don’t need a bunch of fancy equipment for this. It’s one of the reasons I love making bars. Keep it simple.
| Tool | Purpose |
|---|---|
| 9×13 inch Baking Pan | The vessel |
| Parchment Paper | For easy removal |
| Large Mixing Bowl | One bowl wonder |
| Electric Mixer | Handheld or stand |
| Rubber Spatula | For scraping |
| Measuring Cups/Spoons | Accuracy is key |
How to Make These Amazing Bars
Alright, here we go. I’ll walk you through this one step at a time. Don’t rush it, just follow along and you’ll be golden.
Step 1: First thing’s first, preheat your oven to 350°F (175°C). Then, line your 9×13 inch pan with parchment paper, letting some hang over the sides like little handles. This is a game-changer for getting the bars out later.
Step 2: In a medium bowl, whisk together your dry stuff: the all-purpose flour, baking soda, and salt. Just give it a quick mix to combine everything and set it aside for now.
Step 3: Now, in your big bowl, beat the softened butter with the brown sugar and granulated sugar. Use your electric mixer on medium speed for about 2-3 minutes. You want it to look light, pale, and fluffy. This step whips air into the dough, which is important.
Step 4: Add the peanut butter to the butter and sugar mixture. Beat it again until it’s all mixed in and smooth. Don’t forget to scrape down the sides of the bowl with your spatula so you get every last bit.
Step 5: Crack in your two large eggs, one at a time, beating well after each one. Then, pour in the vanilla extract and give it one last quick mix.
Step 6: Time to combine. Dump the dry flour mixture into your wet ingredients. Mix on low speed just until you don’t see any more white streaks of flour. Seriously, stop mixing as soon as it comes together. (More on this in the pro tips section).
Step 7: Gently fold in 1 cup of the semi-sweet chocolate chips with your rubber spatula. We’re saving that extra ½ cup for a reason, so set it aside.
Step 8: Plop the dough into your prepared pan. It’s going to be thick and sticky, so use your spatula or even slightly damp hands to press it evenly into the corners.
Step 9: Sprinkle that remaining ½ cup of chocolate chips evenly over the top of the dough. This makes them look extra pretty and ensures you get chocolate in every single bite.
Step 10: Bake for 25-30 minutes. The edges should be golden brown, and the center should look just set. A toothpick inserted in the middle should come out with a few moist crumbs, but not wet batter.
Step 11: This is the hardest part: let them cool completely in the pan on a wire rack. I know, it’s torture. But cutting into them while they’re warm will give you a gooey mess instead of clean bars. Be patient. It’s worth it.
Pro Tips from My Kitchen
I’ve made these bars more times than I can count, and I’ve learned a few things along the way. These little tricks make a big difference.
- Don’t Overmix the Flour. I mentioned this in the steps, but it’s the single most common cookie mistake. The moment you add flour, you start developing gluten. The more you mix, the tougher that gluten gets. For soft, chewy bars, you want to mix as little as possible once the flour goes in.
- The Parchment Paper Sling. Leaving that extra parchment paper hanging over the sides of the pan is a lifesaver. Once the bars are completely cool, you can just grab the paper “handles” and lift the entire slab right out. It makes cutting them into perfect squares so much easier.
- Underbake, Just a Little. The secret to a perfectly chewy cookie bar is pulling it from the oven when it looks a tiny bit underdone in the very center. The residual heat from the pan will continue to cook it as it cools. This guarantees a soft, gooey middle instead of a dry, cakey bar.
Easy Swaps and Fun Variations
Once you get the basic recipe down, you can have a lot of fun with it. Think of this as your starting point.
| Ingredient Swap | Fun Variation Idea |
|---|---|
| Crunchy Peanut Butter | Adds a nice texture |
| Almond or Cashew Butter | For a different flavor |
| Dark Chocolate Chunks | For a richer taste |
| Milk Chocolate Chips | For a sweeter bar |
| Peanut Butter Chips | Double peanut flavor! |
| Add ½ cup chopped pretzels | For a sweet & salty kick |
| Add ½ cup chopped peanuts | For extra crunch |
You can also try a mix of different chips. My personal favorite is half semi-sweet and half mini peanut butter chips. It’s just a fantastic combination.
Make-Ahead and Storage Tips
Life gets busy, I get it. The good news is these bars are super forgiving and easy to prep ahead of time.
Making the Dough Ahead: You can prepare the cookie dough through Step 7, then cover the bowl tightly with plastic wrap and stick it in the fridge for up to 3 days. When you’re ready to bake, just let it sit on the counter for about 30 minutes to soften slightly, then press it into the pan and bake as directed.
Storing Leftovers: If you somehow have leftovers, store them in an airtight container at room temperature. They’ll stay fresh and chewy for about 4-5 days. I actually think they taste even better on day two after the flavors have had time to settle in. You can also freeze them for up to 3 months. Just stack them in a freezer-safe container with parchment paper between the layers.
Frequently Asked Questions
Here are some common questions I get about this recipe.
Q1. Can I use natural peanut butter?
Ans: I really recommend against it. Natural peanut butter has a different consistency and can make the bars oily and crumbly. Stick with a conventional brand like Jif for the best texture.
Q2. Can I double the recipe?
Ans: Yes, you totally can. Just use a larger half-sheet pan (about 13×18 inches) and add a few extra minutes to the baking time. Keep an eye on it.
Q3. Why did my bars turn out dry and hard?
Ans: This is almost always from one of two things: overmixing the flour, or overbaking. Mix the flour just until it disappears, and pull the bars from the oven when the center still looks a little soft.
Q4. Can I make these gluten-free?
Ans: You can try substituting a good 1-to-1 gluten-free baking flour blend. I’ve had success with brands that contain xanthan gum. The texture might be slightly different, but they should still be delicious.
