White Chocolate Brownies

White Chocolate Brownies are a fudgy, gooey twist on classic brownies—essentially vanilla blondies with an indulgent white chocolate flavour. These bars are soft, slightly chewy and have the delicate sweetness and creamy texture that white chocolate brings. They’re perfect for anyone who loves a lighter, vanilla-forward alternative to a traditional chocolate brownie.

The question often comes up: are these blondies or white chocolate brownies? Traditional blondies are the opposite of chocolate brownies, built around brown sugar and butter with a vanilla base. These bars combine that blondie structure with melted white chocolate, so they sit comfortably between both worlds—blondie in texture and technique, but with a distinct white chocolate character.

Why these turn out so well

The method mirrors many classic brownie or blondie recipes: melt the white chocolate with butter, then beat the egg, sugars and vanilla until light and fluffy. That step introduces air and helps produce a pleasantly crackly top and a tender crumb. Folding the melted chocolate mixture and dry ingredients together yields bars that are soft, slightly dense and rich without being heavy.

Ingredients

• ⅓ cup Butter (75g)
• ¾ cup White chocolate buttons or chopped white chocolate (130g)
• 1 Large egg
• 1 tsp Vanilla extract
• ½ cup Granulated sugar (100g)
• ¼ cup Brown sugar (55g)
• 1 cup All-purpose flour (125g)
• ¼ tsp Baking soda
• ½ cup White chocolate chips (optional) (90g)

Instructions

1. Preheat the oven to 180°C (350°F). Line an 8″x8″ (20cm x 20cm) baking tin with baking paper so the bars are easy to remove.
2. Gently melt the butter and white chocolate together in a heatproof bowl over a pan of simmering water (double boiler method) or carefully in short bursts in the microwave, stirring frequently until smooth.
3. In a separate bowl, beat the egg with the granulated sugar, brown sugar and vanilla extract until the mixture is pale and fluffy. This aeration helps give a light texture and the characteristic crackly top.
4. Fold the melted white chocolate and butter mixture into the egg and sugar mixture until combined.
5. Stir in the flour and baking soda until just mixed. If you like extra pockets of white chocolate, fold in the optional white chocolate chips.
6. Pour the batter into the prepared tin, smoothing the top with a spatula, and bake for 25–30 minutes. The bars should be lightly golden on top but still soft in the centre. A skewer inserted into the middle should come out with a few moist crumbs attached.
7. Allow the bars to cool in the tin, then lift out using the baking paper and cut into 12 pieces. Cooling slightly before slicing helps them hold together while still keeping a soft centre.

Tips and Variations

– For deeper white chocolate flavour, use high-quality white chocolate or combine white chocolate buttons with chopped bar chocolate. Avoid low-quality white chocolate that can be overly sweet and waxy.

– Add a handful of chopped nuts (pecans or macadamia) for texture, or swirl through a thin layer of raspberry jam before baking for a sweet-tart contrast.

– Bake a few minutes less for an extra gooey centre. Keep an eye on them the first time you try the recipe, since oven temperatures vary.

Storage

Store cooled bars in an airtight container at room temperature for several days. You can also refrigerate them to keep them firmer; bring to room temperature before serving for the best texture. For longer storage, freeze individual portions wrapped tightly and thaw at room temperature.

If you try this recipe, I hope you enjoy the balance of sweet white chocolate and the warm, buttery blondie base. These bars are simple to make and a great option when you want a dessert that’s familiar but just a little different from classic chocolate brownies.
