Ingredients

• ½ cup creamy peanut butter – Brings bold peanut butter flavor and makes the bars extra tender and rich.
• 1¾ cups dark brown sugar, packed – Adds sweetness, moisture, and deep caramel-like flavor that gives blondies their signature chew.
• 2 large eggs, at room temperature – Help bind the batter and create structure while keeping the blondies soft.
• ½ teaspoon salt – Balances the sweetness and enhances the peanut butter and chocolate flavors.
• 2 cups all-purpose flour – Gives the blondies structure while still keeping them soft and dense.
• 1 teaspoon baking powder – Adds just enough lift so the bars aren’t too heavy.
• 1½ cups white chocolate chips – Bring creamy sweetness and contrast beautifully with the peanut butter.
• 1 cup peanut butter chips – Double down on the peanut butter flavor and make the blondies extra indulgent.
• 1 teaspoon flaky sea salt, optional – A finishing sprinkle that adds a little crunch and beautifully balances the sweetness.

How to Make Thick and Chewy White Chocolate Peanut Butter Blondies

These easy homemade peanut butter blondies come together quickly and bake up into thick, chewy bars with golden edges and soft centers.

1. Prep the Pan and Oven

Preheat your oven to 350°F. Line a 9×13-inch baking pan with parchment paper, leaving a little overhang on the sides if possible to make lifting the blondies out easier later. Lightly grease the parchment and set the pan aside.

This extra bit of prep makes a big difference when it’s time to cut clean squares.

2. Melt the Butter and Mix the Base

In a medium saucepan over medium heat, melt the butter. Once melted, remove the pan from the heat and stir in the creamy peanut butter and dark brown sugar.

Whisk well until the mixture is smooth, glossy, and fully combined. The warm butter helps the sugar dissolve a bit and creates that rich, chewy blondie base.

3. Add the Eggs

Whisk in the eggs, one at a time, beating well after each addition.

Adding them one at a time helps everything incorporate smoothly and keeps the batter thick and cohesive. The mixture should look glossy and a little lighter once the eggs are fully mixed in.

4. Add the Dry Ingredients

Stir in the salt, flour, and baking powder, mixing just until combined.

Try not to overmix at this stage. Once the flour disappears into the batter, stop stirring. Overmixing can make blondies tougher instead of soft and chewy.

5. Fold in the Chips

Fold in the white chocolate chips and peanut butter chips until they’re evenly distributed throughout the batter.

At this point the batter will be thick—that’s exactly what you want for thick and chewy peanut butter blondies.

6. Spread the Batter in the Pan

Transfer the batter to your prepared 9×13-inch pan and spread it into an even layer.

If you’d like an extra bakery-style finish, sprinkle a few more white chocolate chips and peanut butter chips over the top before baking. It makes the blondies look especially generous and pretty once sliced.

7. Bake in Two Stages

Bake the blondies for 15 minutes. Then loosely cover the pan with aluminum foil and continue baking for another 15 to 18 minutes, or until the edges and top are lightly golden brown.

The foil helps prevent the top from browning too quickly while the center finishes baking. You want the blondies set around the edges with a soft center—they’ll continue to firm up as they cool.

8. Cool Completely Before Slicing

Remove the blondies from the oven and let them cool completely in the pan before cutting.

This part matters more than it might seem. If you cut them too early, they’ll be too soft and may fall apart. Once fully cooled, they slice into neat, thick bars with the perfect chewy texture.

If desired, sprinkle flaky sea salt over the top before or after cooling for a sweet-salty finish.

Tips for Success

• Use room-temperature eggs. They blend more easily into the warm butter mixture and help create a smoother batter.
• Don’t overmix once the flour is added. Stir just until combined to keep the blondies tender.
• Line the pan with parchment. It makes removing and slicing the blondies much easier.
• Cover with foil halfway through baking. This helps the bars bake evenly without overbrowning on top.
• Let them cool completely before cutting. This is key for thick, clean slices and the best chewy texture.
• Add flaky sea salt for balance. A light sprinkle on top makes the sweetness feel more rounded and sophisticated.

Equipment Needed

You don’t need much to make these white chocolate peanut butter blondies, just a few baking basics.

• 9×13-inch baking pan – The ideal size for thick blondies with a soft center.
• Parchment paper – Makes it easy to lift the bars out of the pan.
• Medium saucepan – For melting the butter and mixing the base.
• Whisk – Helpful for blending the butter, peanut butter, sugar, and eggs.
• Spatula or wooden spoon – For folding in the flour and chips.
• Measuring cups and spoons – For accurate baking measurements.
• Aluminum foil – Used to loosely cover the pan halfway through baking.

Recipe Variations

This Thick and Chewy White Chocolate Peanut Butter Blondies recipe is easy to tweak if you want to change the flavor or use what you already have.

1. Use Milk or Dark Chocolate Chips

If white chocolate isn’t your favorite, swap some or all of it for milk chocolate or dark chocolate chips for a deeper chocolate flavor.

2. Add Chopped Peanuts

For extra crunch, fold in a handful of chopped roasted peanuts along with the chips.

3. Swirl in Jam

Drop small spoonfuls of raspberry or strawberry jam over the top of the batter and swirl lightly before baking for a peanut butter and jelly-inspired twist.

4. Make Them Saltier

If you love a sweet-and-salty dessert, add a generous sprinkle of flaky sea salt on top right after baking.

5. Add Vanilla

A teaspoon of vanilla extract stirred into the batter can add another layer of warmth and sweetness if you like.

Serving Suggestions

FAQs

Why are my blondies dry instead of chewy?

The most common cause is overbaking. Blondies should still be a little soft in the center when they come out of the oven because they continue to set as they cool.

Can I use natural peanut butter?

It’s best to use a standard creamy peanut butter for this recipe. Natural peanut butter can separate and may affect the texture of the blondies.

How do I know when blondies are done baking?

The edges and top should be lightly golden and set, while the center may still look slightly soft. They’ll firm up as they cool.

Can I freeze peanut butter blondies?

Yes. Once completely cooled, slice them and store them in an airtight container or freezer bag. Freeze for up to 2 months and thaw at room temperature.

How should I store leftover blondies?

Keep them in an airtight container at room temperature for several days, or refrigerate if your kitchen is especially warm. They stay soft and chewy best when tightly covered.

Can I reduce the amount of chips?

You can, but the generous amount of white chocolate and peanut butter chips is part of what makes these blondies feel so rich and bakery-style.
