    Wonderfully easy to make, these blondies (similar to brownies but light in color) have walnuts, are ready in under an hour, and freeze well. Laced with coffee, they taste like the best giant caramel cookie.

    Are you staring at these wonderful blondie squares?

    They are one of my favorite recipes, full of white chocolate chunks, walnuts, and a dash of coffee that enhances the caramel undertone and pairs wonderfully with the nuts. A mix of flavors I'm completely in love with when it comes to baking.

    They're a favorite here around the holidays, along with the gooey honey walnut squares and the Best Hungarian Shortbread.

    White Chocolate Walnut Blondies

    Ingredients 

    As you can see in the image above, the list of ingredients is pretty straightforward.

    I'm partial to a solid block of chocolate cut into chunks with a big knife, so that's what I used here. Chips get a bit lost in the batter if you ask me, but they work just fine in terms of flavor. 

    • White chocolate: use white chocolate chips or chunks. When available, I like to use Valrhona caramelized chocolate Dulcey, Callebaut white chocolate chunks, or a white chocolate baking bar, coarsely chopped.
    • Walnuts: they will be chopped so you can buy the already broken ones that are cheaper than walnut halves.
    • Brown sugar: use light or dark brown sugar both work. The latter will render a darker dough.
    • Egg: fresh, large.
    • All-purpose flour.
    • Salt: I like to use kosher salt when baking. But regular table salt works just fine.
    • Baking powder: make sure it isn't expired. 
    • Vanilla: I use pure vanilla extract or pure vanilla paste when available, but a good vanilla essence (artificially flavored) also works and is infinitely cheaper. 
    • Coffee: it adds flavor because it enhances the others, like white chocolate and walnuts. If coffee is a no-no, omit it and use more vanilla.

    How to make blondies

    It's an easy, one-bowl recipe.

    Egg added to glass bowl with blondie batter. White surface.

    Mix butter with sugar and add the egg. I use an electric mixer, but it can be made with a stand mixer. 

    Adding vanilla to blondie dough in a glass bowl on a white surface.

    Add flavorings and mix well.

    Flour added to blondie mixture in a glass bowl on a white counter.

    Add dry ingredients. Patiently mix with a spatula or wooden spoon. Or use an electric beater but mix *just* until combined.

    Caramel chocolate chunks added to blondie mixture in a glass bowl. Red spatula and white surface.

    Add the white chocolate and walnuts. Mix until it is well combined and evenly distributed. 

    Vintage Kitchen tip: it's important not to beat much after adding the flour as it will result in tougher blondies. Incorporate it well but stop when it's all integrated.

    Lining the pan 

    I use a square pan, spray or butter it, and line it with a strip of parchment paper almost as wide as the pan (image below). 

    This will aid you when removing the blondie from the pan in a single block. 

    After that, it's easier to cut.

    Variations

    And this is my sophisticated adult version, with the following changes: 

    • Add a tablespoon (or two) of coffee liqueur such as Kahlua to the batter, the drizzle, or both.
    • Use different nuts, a mix of hazelnuts and pecans is my favorite.
    • Add dark, intense chocolate chips, like Ghirardelli 60% Cacao Bittersweet Chocolate Chips.

    The coffee cuts through the extra sweetness of the white chocolate perfectly. It enhances it while letting it remain center stage.

    Add a coffee glaze

    I used to make this blondie recipe with a lot more coffee flavor. And, though I didn't use it today, these white chocolate walnut blondies are fantastic drizzled with a coffee glaze. 

    I still love that variation but find the one posted here happens to be more friendly, especially with kids. 

    Use the traditional powdered sugar glaze, as explained in the Brown Butter Bundt Cake recipe. Or kick it up a notch with a Kahlua glaze, one of my favorites of all time. 

    This white chocolate blondie recipe is versatile and perfect for the holiday season!

    Wonderfully easy to make, these white chocolate walnut bars have a hint of coffee, are ready in under an hour, and freeze very well. They taste like the best giant caramel cookie.

    • Total Time: 1 hour 5 minutes
    • Yield: 9 squares

    Ingredients

    Units
    • 1 tablespoon ground instant coffee
    • 1 tablespoon water
    • 1 teaspoon vanilla extract
    • 2 cups firmly packed brown sugar
    • ¾ cup (180g) unsalted butter
    • 2 large eggs, at room temperature
    • 2 cups (280g) all-purpose flour
    • 2 teaspoons baking powder
    • ½ teaspoon salt
    • 5 oz. (140g) white chocolate chips or chunks
    • ¾ cups (100g) walnuts, coarsely chopped (you can toast them lightly for a better flavor)

    Instructions

    1. Preheat the oven to 350ºF/180°C. 
    2. Butter a 9-inch square cake pan and line the bottom with parchment paper.
    3. Combine coffee and water in a small saucepan and stir until dissolved. 
    4. Over low heat, add sugar and butter and stir until butter melts. 
    5. Turn off heat and let the mixture cool to room tº, stirring occasionally. You can transfer it to a bowl to speed it up.
    6. Add eggs and coffee liqueur to butter mixture and whisk to combine.
    7. Sift flour, baking powder, and salt directly onto butter mixture and stir to blend. 
    8. Stir in chocolate and nuts.
    9. Bake until a tester comes out almost clean, about 35 minutes. Do not over bake or they will be tough. 
    10. Cool in pan on a wire rack for at least 15 minutes. 
    11. Loosen sides with a knife, turn onto a plate, peel off the paper, cut into wedges and serve.

    Notes

    Freezing: you can freeze them for up to a month. I recommend cutting them first when they are cooled down, wrapping in plastic wrap and then in aluminum paper. 

    Variation: this is my sophisticated adult version,
    Add a tablespoon (or two) of coffee liqueur such as Kahlua to the batter, the drizzle, or both.
    Use different nuts, a mix of hazelnuts and pecans is my favorite.
    Add dark, intense chocolate chips, like Ghirardelli 60% Cacao Bittersweet Chocolate Chips.
