Chewy Brown Sugar Chocolate Chip Blondies in 30 Minutes Tips, FAQ & printable recipe

Tips for success

For the best texture, use dark brown sugar rather than light brown sugar. The higher molasses content adds moisture and a deeper, more complex flavor that is essential to the blondie character. If you only have light brown sugar, you can add a tablespoon of molasses to approximate the dark variety.

Chop the chocolate into irregular pieces rather than using uniform chips. This creates pockets of melted chocolate and smaller bits that distribute flavor throughout. If you prefer a more intense chocolate experience, use a 70% cacao bar.

For a milder sweetness, semi-sweet chocolate works well too. The flaky salt should be added immediately after baking so it adheres to the warm, slightly tacky surface.

Variations

• Add Nuts: Fold in 1/2 cup of toasted walnuts or pecans along with the chocolate chunks. The nuts add a crunchy texture and nutty flavor that complements the butterscotch notes of the brown sugar.
• White Chocolate and Raspberry: Replace the bittersweet chocolate with 1 cup of white chocolate chips and gently fold in 1/2 cup of fresh raspberries. The tartness of the berries cuts through the sweetness, and the white chocolate melts into creamy pockets.
• Peanut Butter Swirl: After spreading the batter in the pan, dollop 1/4 cup of creamy peanut butter on top and swirl it with a knife. The peanut butter adds a savory depth that pairs beautifully with the chocolate and brown sugar.
• Bourbon and Caramel: Add 1 tablespoon of bourbon to the butter mixture along with the vanilla. After baking, drizzle with caramel sauce before sprinkling with flaky salt. The bourbon adds a warm, smoky complexity, and the caramel enhances the butterscotch flavor.

Storage and make-ahead

Fridge

Store blondies in an airtight container in the refrigerator for up to 1 week. Bring to room temperature or warm slightly before serving.

Freezer

Wrap cooled blondies tightly in plastic wrap and then in foil. Freeze for up to 3 months. Thaw at room temperature or reheat in a 350°F oven for 5-7 minutes.

Reheat

Reheat individual blondies in the microwave for 10-15 seconds or in a 300°F oven for 5 minutes until warm and gooey.

Store blondies in an airtight container at room temperature for up to 4 days. Place a piece of parchment paper between layers to prevent sticking.

If the blondies become too soft, they can be refrigerated for up to a week, but bring them to room temperature before serving for the best texture. The edges may lose some crispness over time, but the centers will remain chewy.

The blondie batter can be prepared up to 2 days in advance and kept covered in the refrigerator. Bring it to room temperature for 30 minutes before spreading in the pan and baking.

Alternatively, bake the blondies completely, let them cool, and store them in an airtight container for up to 3 days. They can also be frozen for longer storage; see the freezer instructions.

Serving ideas

Serve blondies warm for the ultimate gooey chocolate experience. A few minutes in a 300°F oven or a quick zap in the microwave will restore that just-baked texture. Pair them with a glass of cold milk or a scoop of vanilla ice cream for a decadent dessert. The flaky salt on top will shine when the blondies are warm, as it contrasts with the sweet, buttery base.

For a more elegant presentation, cut the blondies into smaller squares and serve them on a platter with fresh berries. They also make excellent lunchbox treats or picnic desserts.

The chewy texture holds up well, and the chocolate chunks stay soft even at room temperature. If serving at a party, consider dusting with a little confectioners' sugar just before serving for a pretty finish.

Chewy Brown Sugar Chocolate Chip Blondies in 30 Minutes

Prep 10 minCook 20 minTotal 30 minServes 9

Ingredients

• 1/2 cup salted butter, softened
• 1/2 cup dark brown sugar, packed
• 1/4 cup granulated sugar
• 1 large egg
• 1 tsp pure vanilla extract
• 1 cup all-purpose flour
• 1/4 tsp espresso powder
• 1 cup rough-chopped bittersweet dark chocolate chunks
• Flaky sea salt, for sprinkling, to taste

Instructions

1. Heat the oven to 350°F (175°C). Line an 8x8-inch baking pan with parchment paper, leaving overhang on two sides for easy lifting. In a large bowl, beat the softened salted butter, dark brown sugar, and granulated sugar with an electric mixer on medium speed until pale, smooth, and glossy, about 2 minutes. Add the egg and vanilla extract, then beat until fully incorporated, scraping down the sides as needed.
2. In a small bowl, whisk together the all-purpose flour and espresso powder. Add the flour mixture to the butter mixture and fold gently with a rubber spatula until just combined. The batter will be thick. Fold in the rough-chopped bittersweet dark chocolate chunks until evenly distributed, being careful not to overmix.
3. Scrape the batter into the prepared pan and spread it into an even layer. Bake at 350°F (175°C) for 20 minutes, or until the edges are caramelized and shiny and the center is set but still moist. The top should be golden brown, and a toothpick inserted into the center should come out with a few moist crumbs attached.
4. Immediately after removing the blondies from the oven, sprinkle the top with flaky sea salt while the surface is still hot. The salt will stick to the glossy, caramelized top. Let the blondies cool in the pan on a wire rack for at least 15 minutes before slicing.
5. Using the parchment overhang, lift the entire blondie block out of the pan and onto a cutting board. Use a sharp chef's knife to cut into 9 squares (3 rows by 3 rows). Serve warm for the ultimate chewy texture, or at room temperature. The centers will be moist and tender, with melted chocolate pools throughout.
