- 170 g butter salted or unsalted
- 200 g soft brown sugar
- 1 large egg
- 1 tablespoon instant espresso powder / coffee powder
- 1 teaspoon vanilla extract
- 190 g all-purpose flour
- 3/4 teaspoon baking powder
- ½ teaspoon salt
- 170 g dark chocolate chips or chunks
Let the butter melt in a light-colored saucepan over medium heat. Once melted, keep cooking for around 4-5 minutes, stirring regularly, until the milk solids have caramelized and the butter smells nutty. Pour the browned butter into a large heatproof bowl (including all the dark bits from the bottom of the pan) and let it cool for 15 minutes. 170 g butter
Preheat the oven to 350°F (180°C). Line an 8x8-inch (20x20cm) baking pan with parchment paper.
Once the butter has cooled, add the brown sugar, egg, espresso powder, and vanilla. Whisk until smooth and well combined. 200 g soft brown sugar, 1 large egg, 1 tablespoon instant espresso powder / coffee powder, 1 teaspoon vanilla extract
In a small bowl, whisk together the flour, baking powder, and salt. 190 g all-purpose flour, 3/4 teaspoon baking powder, ½ teaspoon salt
Add the dry ingredients to the wet ingredients and fold with a rubber spatula until combined into a thick, glossy batter. Fold through the chocolate chips. 170 g dark chocolate chips
Press the blondie dough into the prepared baking pan and smooth with an offset spatula. Press a few extra chocolate chips or chunks on top.
Bake for 25-28 minutes, or until the middle has set and a toothpick inserted into the center comes out with a few moist crumbs. Don't overbake for fudgy blondies.
Let cool completely in the pan on a wire rack. Sprinkle with flaky salt to serve (optional).
- Measurements: Both grams and US cup sizes are provided. Use the toggle on the recipe card to switch between the two.
- Storing: Keep in an airtight container at room temperature for up to a week, or freeze for up to 3 months.
- Espresso powder: I use instant espresso powder because it dissolves completely. Regular espresso grounds will leave a gritty texture.
- Chocolate: I use dark chocolate, but milk or white chocolate work too.
- Brown butter: Use a light-colored pan so you can see the butter changing color. It should be a deep amber with a nutty smell. If you're new to it, check out my how to brown butter guide.
- Don't overbake: Pull them out when a toothpick still has moist crumbs. They set further as they cool.
