Brown Butter Blondies

Sweet, rich, chewy, butterscotchy - these taste divine! The brown butter filling takes them on another level by adding a soft toasty caramel goodness in the centre of these blondies. Toasted almonds add to the crunch.

Ingredients

Brown Butter Batter

  • 113 g unsalted butter
  • 150 g light brown sugar
  • 1 egg
  • 1 tsp vanilla extract
  • 40 g all-purpose flour
  • ½ tsp salt

Blondie Batter

  • 300 g all-purpose flour
  • tsp baking powder
  • 1 tsp salt
  • 227 g unsalted butter - softened at room temperature
  • 300 g light brown sugar
  • 2 eggs
  • 1 tsp vanilla extract
  • 1-1½ cup almonds - lightly toasted and chopped coarsely

Instructions

Brown Butter Batter

  • First, make the brown butter. Keep a small bowl/mug with a strainer ready on the side. In a medium saucepan, heat the butter over low-medium heat while stirring occasionally. For the initial few minutes, it'll bubble and foam a lot as the water in butter evaporates. Only after it reaches the temperature where most water is gone, the milk solids will start to brown and you'll start seeing small brown flecks at the bottom. Once you're happy with the browning (neither light nor burnt), remove the pan from the heat and strain the liquid into your bowl to catch the brown bits. Let the liquid cool down slightly for about 5-10 minutes.
  • Add the egg, vanilla and brown sugar and beat them with a whisk till well combined and you see a ribbon form. This will take about 3-4 minutes. Fold in the flour until just combined. Keep it aside.

Making Blondies

  • Preheat the oven to 180C. Line a 13"x9" sheet with parchment paper and butter the sides and corners.
  • In a bowl, whisk together the flour, baking powder and salt. Keep it aside.
  • In your stand mixer with paddle attachment (or use a hand mixer), beat the butter and brown sugar for 5 minutes till it gets light and fluffy. Add the eggs one a time and beat just until combined. Add the vanilla and mix.
  • Mix the flour in at the lowest speed until no dry flour remains. Add half of the chopped almonds and mix.

Assembly & Baking

  • Spread about 3/4 of the blondie batter into the baking pan. It might be a little dry batter and using an offset spatula (something like this) helps to spread it evenly. It might be a thin layer but that's okay.
  • Dollop the brown butter mixture on top of the layer and spread the remaining blondie batter in between the dollops. Spread as much as possible (doesn't matter if the batters mix in, it all bakes out fine).
  • Bake the blondies for about 27-30 minutes - it'll be golden brown and firm (though the toothpick test might not come clean due to the caramel ribbon). Remove from oven and let the blondie cool inside the pan for about 10 minutes. Remove from pan and cool completely over a wire rack.
  • Ensure the blondie is completely cooled down before cutting into slices - as big or small as you like them to be.
  • These stay good for about a week at room temperature stored in an airtight container.
