Why You’ll Love This Recipe
- One-bowl simplicity: No stand mixer required, no fussy steps. Melt, mix, fold, bake – you’ll have blondies in under an hour with minimal cleanup.
- Perfectly thick & chewy: The secret? A combination of melted butter, brown sugar, and a foil-covered bake that keeps the center soft while the edges get that irresistible golden chew.
- Peanut butter meets white chocolate: Creamy peanut butter and sweet white chocolate chips are a match made in dessert heaven. Add peanut butter chips for double the nutty bliss, and a sprinkle of flaky salt to make it pop.
- Flexible & forgiving: Want less sugar? Reduce brown sugar to 1 cup. Need a fiber boost? Swap in whole wheat pastry flour. Even a coconut oil swap works – these blondies take to substitutions like a champ.
Ingredients
- ½ cup unsalted butter, melted (or coconut oil for a lighter swap)
- ½ cup creamy natural peanut butter
- 1¾ cups dark brown sugar (can be reduced to 1 cup for lower sugar)
- 2 large organic eggs, at room temperature
- ½ teaspoon fine sea salt
- 2 cups all-purpose flour (or whole wheat pastry flour for extra fiber)
- 1 teaspoon baking powder
- 1½ cups white chocolate chips
- 1 cup peanut butter chips
- 1 teaspoon flaky sea salt, for sprinkling (optional)
How to Make Thick and Chewy White Chocolate Peanut Butter Blondies
- Preheat & prep: Set your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving an overhang on two sides. Give it a light spray of non-stick cooking oil – this makes lifting the blondies out a breeze.
- Mix the wet base: In a large bowl, whisk together the melted butter, creamy peanut butter, and dark brown sugar until smooth and glossy. No lumps allowed!
- Add eggs one at a time: Crack in the eggs one by one, whisking gently after each addition until fully incorporated. The batter will look thick and dreamy.
- Fold dry ingredients & chips: Using a spatula, gently fold in the salt, flour, and baking powder – mix only until you see no more streaks of flour. Then fold in the white chocolate chips and peanut butter chips. Be careful not to overmix; a light hand keeps the blondies tender.
- Spread & top: Scrape the batter into the prepared pan and spread it evenly. If you want a pretty top, sprinkle a few extra chips over the surface before baking.
- Bake with a foil trick: Bake uncovered for 15 minutes. Then cover the pan loosely with aluminum foil (this prevents the top from over-browning while the center stays soft). Bake for another 15–18 minutes, until the edges are lightly golden and a toothpick inserted in the center comes out with moist crumbs – not wet batter.
- Cool completely: Let the blondies cool in the pan on a wire rack. This is crucial for setting that chewy texture. After about 1 hour, lift out the parchment, slice into 16 squares, and serve.
Ways to Serve & Present These Blondies
Whether you’re hosting a party or just treating yourself, these Thick and Chewy White Chocolate Peanut Butter Blondies are incredibly versatile. Here are some fun ideas:
- Ice cream sandwich: Cut a blondie in half horizontally, sandwich a scoop of vanilla or chocolate ice cream inside, and roll the edges in crushed peanuts. Instant showstopper!
- Blondie sundae: Warm a square for 10 seconds in the microwave, top with a scoop of ice cream, drizzle with caramel sauce, and sprinkle with flaky salt.
- Gift boxes: Wrap individual blondies in wax paper and tie with twine. Perfect for bake sales, neighbor gifts, or party favors.
- Mini blondie bites: Use a mini muffin tin (bake 10–12 minutes) for pop‑size treats. Great for lunchboxes or snack platters.
- Deconstructed parfait: Crumble blondies into a glass, layer with whipped cream, peanut butter drizzle, and extra white chocolate chips.
Pro tip: serve at room temperature for the ultimate chewy texture – or slightly warm for gooey chips that stretch with every bite.
How to Store & How Long They Last
These blondies stay wonderfully soft and chewy for days if stored properly. Here’s what to do:
- At room temperature: Place them in an airtight container with a slice of bread – the bread absorbs excess moisture and keeps the blondies fresh. They’ll last 4–5 days.
- In the refrigerator: Store in a sealed container for up to 1 week. Let them sit at room temp for 15 minutes before eating to bring back the chew.
- Freezer-friendly: Wrap each blondie individually in plastic wrap, then place in a freezer bag. They freeze beautifully for up to 3 months. Thaw at room temperature or pop in the microwave for 15 seconds.
Note: Because these blondies are moist, avoid storing them in paper bags or open containers – they’ll dry out fast.
Frequently Asked Questions
Absolutely! Crunchy peanut butter adds extra texture. Just keep in mind that the white chocolate and peanut butter chips already add crunch, so creamy keeps the chew smoother.
Overbaking is the usual culprit. Follow the foil‑cover method and check the center early. Also, measure your flour correctly – scoop and level, don’t pack.
Yes! The recipe notes you can cut brown sugar to 1 cup. The blondies will be slightly less sweet and a bit less tender, but still delicious. You may need to reduce baking time by a couple minutes.
Of course – dark or milk chocolate chips work, but the white chocolate balances the peanut butter beautifully. You can also use butterscotch chips for a caramel‑like twist.
Look for golden edges and a slightly puffed top. A toothpick inserted in the center should come out with a few moist crumbs – not wet batter. The center will look underdone; that’s okay, it sets as it cools.
Yes! Use a 1:1 gluten‑free all‑purpose baking flour blend. For best results, add ¼ teaspoon xanthan gum if your blend doesn’t already include it.
That final sprinkle is not optional if you love sweet‑salty magic! Flaky salt cuts through the richness and enhances every flavor – it’s a game changer.
The recipe calls for dark brown sugar because it has more molasses, giving deeper flavor and extra chewiness. Light brown works too, but your blondies will be slightly lighter in taste and texture.
Yes, it should be a thick, scoopable dough – not a runny batter. That thickness is what gives these blondies their signature dense, chewy texture. Don’t add extra liquid!
Certainly! Double everything and use a half‑sheet pan (18×13 inches). Bake the same way – covered with foil after 15 minutes – but expect an extra 5‑8 minutes in the oven. Check for doneness with a toothpick.
There you have it – the ultimate Thick and Chewy White Chocolate Peanut Butter Blondies. Go ahead, bake a batch, and watch them disappear. You deserve this sticky, salty, sweet slice of happiness. Happy baking!
