Description
These ultra-fudgy brown butter blondies are dense, chewy, and packed with toffee crunch. The brown butter adds a deep, nutty flavor that elevates this simple dessert into something truly special.
Ingredients
Scale
- 1 cup (226g) unsalted butter
- 1 ½ cups (300g) light brown sugar
- 1 cup (200g) granulated white sugar
- 2 large eggs, room temperature
- 2 teaspoons vanilla extract
- ½ teaspoon fine sea salt
- 2 cups (250g) all-purpose flour
- ½ teaspoon baking powder
- 1 ½ cups toffee bits (mix of small chips and larger chunks)
- Sea salt flakes (optional, for topping)
Instructions
- Preheat oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper.
- Melt butter in a large skillet over medium heat. Stir constantly until it foams, settles, and turns a deep golden amber color with a nutty aroma (about 250°F). Immediately remove from heat and pour into a heat-proof bowl. Let cool for 10-15 minutes until warm but not hot.
- In a large mixing bowl, combine the cooled brown butter, light brown sugar, and granulated sugar. Whisk vigorously for about 2 minutes until glossy and thickened.
- Add eggs one at a time, whisking well after each addition. Add vanilla extract and salt. Whisk until smooth.
- Sift all-purpose flour and baking powder over the wet mixture. Gently fold in with a spatula until no streaks of flour remain. Do not overmix.
- Fold in the toffee bits until evenly distributed.
- Spread batter into the prepared pan. Bake for 30-35 minutes. Pull out when edges are golden and the center is still slightly soft/jiggly.
- Let cool in the pan for at least 20 minutes before lifting out with parchment sling and slicing. Sprinkle with sea salt flakes if desired.
Notes
The brown butter is the key to flavor; watch it closely to avoid burning. Do not overbake; the center should remain slightly soft as they continue to cook in the pan. For best texture, let them cool completely. They taste even better the next day.
