"Brown on Blonde" Blondies

From the kitchen of Carly

Brown butter meets nutty blondies in this chewy, sophisticated bar. Toasted walnuts and pecans anchor dark brown sugar and almond butter for depth, while the browned butter adds that essential hazelnut edge. Dense, rich, and gloriously simple.

"Brown on Blonde" Blondies

Brown butter does the real work here, turning simple blondies into something nutty and complex. Walnuts and pecans toast right in the fat, so you get maximum flavor without extra steps. The almond butter adds richness and a subtle nuttiness that layers with the brown sugar, while deeply browned edges and a cracked top signal you've baked them exactly right. Dense, chewy, unapologetically buttery.

Ingredients

4 servings

  • 6 oz(170 g)unsalted butter
  • 3 1/2 oz(100 g)walnuts
  • 2 oz(55 g)pecans
  • 10 oz(272 g)all-purpose flour
  • 1/4 oz(6 g)baking powder
  • 0 oz(3 g)kosher salt
  • 2 oz(55 g)almond butter
  • 12 oz(346 g)dark brown sugar
  • 2 largeeggs
  • 1 largeegg yolk
  • 1 tbspvanilla extract

Instructions

  1. Crank the oven to 350°F. Coat the insides of an 8 inch square baking pan with non-stick cooking spray and line with a parchment paper sling.

  2. Melt the butter in an 8 inch sauté pan over medium heat. Once the bubbling subsides, drop in the walnuts and pecans and cook until the nuts toast and the butter smells nutty, 5 to 7 minutes.

  3. Meanwhile, whisk the flour, baking powder, and salt together in a small bowl.

  4. Position a fine-mesh strainer over a large heatproof bowl and strain the butter away from the nuts. Set both aside to cool for 30 minutes. Then coarsely chop the nuts and set aside.

  5. While you wait, beat the almond butter into the cooled butter, followed by the brown sugar, eggs, egg yolk, and vanilla. Beat until completely smooth, around 1 minute, then fold in the flour mixture. Finish by folding in the nuts and transferring to the prepared pan. The batter runs thick, so a rubber or silicone spatula works best.

  6. Bake for 30 to 35 minutes, until the edges turn deeply brown and the top reads dry and cracked. Lift from the pan using the parchment sling and cool on a rack for around 30 minutes. Slice into squares and serve with cold almond milk alongside.

Tips from the kitchen

  • Strain the nuts from the brown butter immediately after toasting, then let both cool separately. The butter cools faster this way, and you avoid overcooking the nuts while you wait.
  • Don't skip the 30-minute cool down for the brown butter. You want it at room temperature before beating in the almond butter and sugar, or the eggs will scramble.
  • Chop the cooled nuts coarsely and fold them in last. This keeps them from breaking down into dust and gives you actual texture bites in every square.
  • Bake until the top looks dry and cracked and the edges are deeply browned. The center will still be tender, but underbaking here means a gummy, greasy result.

Variations

  • All-walnut: Skip the pecans and double the walnuts for a stronger, more assertive flavor that won't get lost in the brown sugar.
  • Tahini instead of almond butter: Swap in tahini for a slightly savory, earthy twist that sharpens the nuttiness of the brown butter.
  • Sea salt finish: Sprinkle fleur de sel on top after baking while the blondies are still warm to amplify the brown sugar and butter.
  • Brown sugar swapped for muscovado: Use dark muscovado for deeper molasses notes and a chewier, more compact crumb.

Make ahead and storage

Blondies keep in an airtight container at room temperature for up to 5 days. They don't freeze well due to the high butter content, which can separate and turn the crumb grainy when thawed.
