Chewy Brown Sugar Chocolate Chip Blondies in 30 Minutes

If you love chewy cookies and fudgy brownies, these brown sugar chocolate chip blondies are perfection! They come together in one bowl with just a handful of pantry staples.

The combination of dark brown sugar, vanilla, and bittersweet chocolate creates a deep butterscotch flavor, while the flaky salt on top adds a savory crunch. Ready in under 30 minutes, these blondies are the ultimate quick dessert for any occasion.

Blondies are the understated cousin of brownies—no cocoa, but plenty of buttery, caramel-like sweetness. This version uses dark brown sugar for extra molasses depth and a generous amount of rough-chopped bittersweet chocolate for rich, gooey pockets.

The result is a bar that's chewy at the edges, tender in the center, and studded with melted chocolate. A sprinkle of flaky sea salt right out of the oven takes them from good to unforgettable. Perfect for weeknight cravings or casual gatherings, these blondies prove that simple ingredients can yield something truly special.

Ingredients

Why this recipe works

The method here relies on whipping softened butter with both dark brown sugar and granulated sugar. This creates air pockets that give the blondies a light, chewy texture rather than a dense, cakey one.

Dark brown sugar brings extra moisture and a deep molasses flavor that caramelizes beautifully as the bars bake, producing those shiny, crackly edges that are the hallmark of a great blondie.

Folding the flour gently and using just enough to hold the batter together keeps the crumb tender. The espresso powder, though a tiny amount, enhances the chocolate flavor without adding any coffee taste.

The rough-chopped chocolate chunks melt into puddles rather than remaining as distinct chips, giving every bite a luxurious, fudgy surprise.

Notes and substitutions

Use high-quality bittersweet chocolate (60-70% cacao) for the best flavor and meltability. The chocolate chunks should be roughly chopped into varied sizes—some larger pieces will melt into pools, while smaller bits disperse throughout. If using chocolate chips, choose a high-quality brand with a high cocoa content for a more intense taste.

Salted butter is called for here because it adds a subtle savory note that balances the sweetness. If you only have unsalted butter, add 1/4 teaspoon of salt to the flour mixture. The flaky sea salt is essential—do not skip it. It provides a textural contrast and brightens the overall flavor. Maldon or fleur de sel are excellent choices.

• salted butter: Unsalted butter plus 1/4 teaspoon salt can replace salted butter. If using unsalted, add the salt to the flour mixture.
• dark brown sugar: Light brown sugar can be used, but the molasses flavor will be slightly milder and the blondies a touch less chewy.
• bittersweet dark chocolate chunks: Semi-sweet chocolate chips or chopped milk chocolate work well, though the flavor will be sweeter and less intense.
• espresso powder: Instant coffee granules crushed to a powder can be used. Or omit it altogether for a purely butterscotch flavor.
