What You’ll Need: Ingredients with Tips and Tricks
These ingredients are simple, but each plays a key role in making the bars chewy and flavorful. Here’s why these choices work best.
- 1/2 cup unsalted butter, melted – Adds richness and helps the bars stay soft. Make sure it’s slightly cooled before using.
- 1/2 cup light brown sugar – Offers moisture and a mild caramel flavor.
- 1/2 cup dark brown sugar – Deepens the flavor with a hint of molasses. You can use just one type if preferred.
- 2 eggs, room temperature – Helps bind everything together and gives structure.
- 1 tsp vanilla extract – Enhances the sweet and nutty flavor.
- 3/4 cup creamy peanut butter – Choose high-quality peanut butter for the best taste. Crunchy works too for added texture.
- 1 1/2 cups all-purpose flour – Standard base for chewy bars.
- 1/2 tsp baking soda – Assists with a slight rise and prevents the bars from being too dense.
- 1 tsp cornstarch – Adds softness and chewiness.
- 3/4 cup semi-sweet chocolate chips – Perfect balance of sweet and bitter. Toss in a few extra on top for visual appeal.
Note: This recipe yields about 9 rich bars. Perfect for sharing or indulging solo.

How to Make Peanut Butter Chocolate Chip Bars?
Follow these easy steps to create a pan of warm, gooey perfection. No fancy techniques—just simple steps that anyone can do.
Step 1: Preheat and Prep the Pan
Start by preheating your oven to 350°F (176°C). Grease an 8×8-inch baking pan and line it with parchment paper. This helps the bars come out clean with no sticking.
Step 2: Mix the Dry Ingredients
In a medium bowl, stir together the all-purpose flour, baking soda, and cornstarch. These will be the dry base of your batter. Set aside once combined.
Step 3: Blend the Wet Ingredients
In a large mixing bowl, whisk the melted and slightly cooled butter with both sugars until smooth. This gives the bars a rich, caramelized base. Then add in the eggs and vanilla extract. Keep whisking until air bubbles form.
Step 4: Add Peanut Butter Goodness
Now stir in the creamy peanut butter until everything is silky and well-blended. This is when the batter starts smelling heavenly!
Step 5: Combine and Fold
Add the dry ingredients into the wet. Use a spatula to gently fold them together until no streaks of flour remain. Be careful not to over-mix. Gently fold in the chocolate chips.
Step 6: Transfer and Bake
Scoop the dough into your prepared pan and spread it evenly. Sprinkle a few extra chocolate chips over the top for a pretty finish. Bake for 28–35 minutes, or until a toothpick comes out with moist crumbs.

Tips from My Kitchen to Yours
I’ve made this recipe a few times now, and here’s what I learned along the way to make it even better.
- Use fresh peanut butter for a smoother blend. Avoid natural peanut butter that separates.
- Always cool the butter slightly before mixing it with sugar—it prevents scrambled eggs!
- Don’t overbake. It’s okay if the center looks soft; it firms up as it cools.
- Let the bars rest in the pan for 15–20 minutes before slicing for neater edges.
- For a more decadent bite, drizzle with melted chocolate or peanut butter on top after baking.

Common Mistakes to Avoid for Better Results
Watch out for these small mistakes that can affect your outcome. I’ve made a couple of these before and learned my lesson!
- Overbaking: This dries out the bars. Aim for that soft center.
- Using cold eggs: Always use room temperature eggs for smoother blending.
- Over-mixing the dough: This makes the bars tough. Mix just until combined.
- Wrong pan size: An 8×8-inch pan gives the perfect thickness. Larger pans result in thinner, dry bars.
- Skipping parchment paper: It’s essential for clean removal and even baking.
