Ingredients You’ll Need
Don’t let the small number of ingredients fool you; each plays a crucial role in delivering the Ultimate White Chocolate Walnut Blondies Recipe’s perfect texture and flavor. From the nutty richness of browned butter to the sweet burst of white chocolate, every item is essential.
- Unsalted butter (125g/8 tbsp): Browning the butter adds a deep, nutty flavor that takes the blondies to a whole new level.
- Brown sugar (1 cup): Adds moisture and caramel undertones that make the blondies chewy and flavorful.
- Large egg (1): Binds the ingredients while adding richness and tenderness.
- Vanilla extract (1 tsp): Enhances the sweetness and complements the white chocolate beautifully.
- Plain/all-purpose flour (1 cup): Provides structure without weighing the blondies down.
- Cooking salt/kosher salt (1/4 tsp): Balances the sweetness and magnifies flavors.
- White chocolate chips (1 cup): Creates pockets of creamy sweetness throughout.
- Walnuts (1/2 cup, roughly chopped): Toasted for crunch and a toasty counterpoint to the sweet chips.
- Sea salt flakes (1/4 tsp): Optional but highly recommended for that delightful finishing contrast.
How to Make Ultimate White Chocolate Walnut Blondies Recipe
Step 1: Prepare Your Pan and Toast the Walnuts
First things first, preheat your oven to 180°C/350°F (160°C fan-forced) so it’s ready to bake the moment your batter is set. Grease an 8-inch square pan with butter and line it with baking paper—this step ensures your blondies come out easily and keeps the edges beautifully crisp. While the oven is heating, spread the walnuts on a tray and toast them for 5 minutes. This simple toast deepens their flavor and adds a lovely crunch that contrasts perfectly with the soft blondies.
Step 2: Brown the Butter for Rich, Nutty Goodness
This step is the secret superstar of this Ultimate White Chocolate Walnut Blondies Recipe, so don’t skip it! Melt the butter in a silver saucepan over medium-high heat, then lower to medium to simmer gently for 3 to 4 minutes. You’ll notice it foam, smell that irresistible nutty aroma, and see golden specks—these little bits are flavor gold. Pour the browned butter with all its delicious flakes into a bowl right away to preserve that awesome taste.
Step 3: Mix Sugar and Butter, Then Add Egg and Vanilla
While the browned butter is still warm, stir in the brown sugar. Using a wooden spoon, combine until smooth. Let the mixture cool for about 3 minutes so it doesn’t cook the egg in the next step. Then crack in the egg and add the vanilla extract, mixing until everything is just combined and glossy. At this point, you’ll notice the batter starting to thicken with richness.
Step 4: Add Flour, Salt, White Chocolate, and Walnuts
Time to build the blondie base. Stir in the flour and salt carefully just until everything comes together — the batter should be thick, almost like a dough you could roll out. Next, fold in those white chocolate chips and toasted walnuts gently, so every bite is full of melty sweetness and satisfying crunch. This is where the Ultimate White Chocolate Walnut Blondies Recipe really starts to take shape!
Step 5: Bake to Golden Perfection
Scrape your luscious batter into the prepared pan and use your hands to smooth the surface evenly. Pop it into the oven for about 25 minutes. Keep an eye out for those edges turning lightly golden and a paper-thin crackly top forming — this means your blondies are perfectly baked. They should still feel a little soft in the center for that dreamy fudgy texture.
Step 6: Cool, Salt, and Slice
Once baked, allow your blondies to rest in the pan for 10 minutes before carefully lifting them out using the parchment paper. Cool them another 10 minutes or so on a cutting board; this helps the center set perfectly without becoming too gooey. If you love a sprinkle of salt to enhance sweetness, now’s the time to scatter sea salt flakes on top. Slice into 16 squares or 9 giant ones — then get ready to delight in chewy, nutty bliss!
How to Serve Ultimate White Chocolate Walnut Blondies Recipe
Garnishes
A quick sprinkle of flaky sea salt on top just before serving intensifies the white chocolate’s sweetness and adds a sophisticated touch. You could also dust lightly with powdered sugar for a pretty, festive look or drizzle melted white chocolate on top for extra indulgence.
Side Dishes
Pair these blondies with a scoop of vanilla ice cream or a dollop of freshly whipped cream for an irresistible dessert experience. They also go wonderfully with fresh berries or a cup of rich coffee or hot chocolate, making any coffee break feel special.
Creative Ways to Present
Serve the blondies warm in a rustic wooden tray lined with parchment paper for a cozy casual vibe. For a party, cut them into smaller bite-sized squares and stack them on a tiered cake stand. Wrapping individual squares in parchment and tying with twine turns them into perfect homemade gifts everyone will rave about.
Make Ahead and Storage
Storing Leftovers
Store any leftover Ultimate White Chocolate Walnut Blondies Recipe in an airtight container at room temperature for up to 4 days. They stay chewy and delicious, and the flavors even meld slightly, making each bite better as time passes.
Freezing
Want to keep them longer? Wrap the blondies tightly in plastic wrap and place them inside a freezer bag or container. They freeze beautifully for up to 3 months. When ready, thaw overnight in the fridge or at room temperature.
Reheating
To enjoy warm blondies, reheat individual squares in the microwave for 10 to 15 seconds or pop them in a warm oven (around 150°C/300°F) for about 5 minutes. This brings back their gooey, just-baked magic!
FAQs
Can I substitute the walnuts with another nut?
Absolutely! Pecans, almonds, or even macadamia nuts work wonderfully and provide a different but equally delightful crunch and flavor. Just toast them as you would the walnuts for the best taste.
Why is browning the butter important for this recipe?
Browned butter adds a rich, nutty depth that plain melted butter can’t match. It enhances the complex flavors of the blondies and creates a truly memorable taste that’s part of what makes this the Ultimate White Chocolate Walnut Blondies Recipe.
Is it okay to use white chocolate chunks instead of chips?
Definitely! White chocolate chunks will add more uneven, melty pockets of sweetness, which can be lovely if you prefer bigger bursts of creamy white chocolate in each bite.
Can I make these blondies gluten-free?
Yes! Swap the plain flour with a 1:1 gluten-free baking flour blend. Just be sure it includes a binder like xanthan gum to keep the texture fudgy and moist.
How do I know when the blondies are perfectly baked?
Look for lightly golden edges and a crackly, thin crust on top. The center should still feel slightly soft when you give a gentle press — it will set further as it cools, giving you that perfect chewy texture.

Description

Ingredients
Butter & Sugar
- 125g/8 tbsp (1 US stick) unsalted butter
- 1 cup brown sugar (light brown sugar preferred, dark brown also acceptable)
Wet Ingredients
- 1 large egg (~50g/2 oz)
- 1 tsp vanilla extract
Dry Ingredients
- 1 cup all-purpose flour
- 1/4 tsp kosher salt (halve if using table salt)
Add-ins
- 1 cup white chocolate chips
- 1/2 cup walnuts, roughly chopped
- 1/4 tsp sea salt flakes (optional, for sprinkling)
Instructions
- Preheat and Prepare Pan: Preheat your oven to 180°C/350°F (160°C fan-forced). Grease an 8-inch (20 cm) square pan with butter and line it with parchment paper to prevent sticking.
- Toast Walnuts: Spread the roughly chopped walnuts on a baking tray and roast them in the oven for 5 minutes to bring out their flavor. Remove and let cool.
- Brown the Butter: Place the unsalted butter in a silver saucepan over medium-high heat. Once melted, reduce the heat to medium and let it simmer gently for 3 to 4 minutes. Stir occasionally as it foams and watch for golden specks and a nutty aroma—this indicates browned butter. Immediately transfer the butter with the solids into a bowl to prevent burning.
- Mix Batter: Stir the brown sugar into the warm browned butter until combined. Let the mixture cool for 3 minutes to avoid cooking the egg in the next step. Add the egg and vanilla extract, mixing thoroughly. Then fold in the flour and salt until you have a thick, dough-like batter. Finally, fold in the toasted walnuts and white chocolate chips evenly.
- Bake the Blondies: Scrape the batter into the prepared pan and smooth the surface with your hands or a spatula. Bake in the preheated oven for 25 minutes or until the edges are lightly golden and the top has a thin, crackly layer.
- Cool and Serve: Let the blondies rest in the pan for 10 minutes. Then lift them out onto a cutting board and cool for at least another 10 minutes to set properly. If desired, sprinkle with sea salt flakes before cutting into 16 squares or 9 larger squares. Enjoy!
Notes
- Using a silver saucepan for browning butter helps achieve better color and flavor compared to darker pans.

- Cooling the batter slightly before adding the egg prevents cooking the egg prematurely.
- Toasting the walnuts intensifies their flavor and adds a pleasant crunch.
- The sea salt flakes on top provide a nice contrast to the sweetness and balance the flavors.
