Ingredients

  • 1 ½ sticks 170g butter, unsalted
  • 1/2 teaspoon sea salt
  • ¾ cups brown sugar 150g
  • ⅓ cup fine granulated sugar plus 1 tablespoon, 80g
  • 3 egg yolks from 3 large eggs
  • 1 tablespoon plain yogurt
  • 1 teaspoon vanilla
  • ¾ teaspoon baking soda
  • 200 g flour
  • 100 g dark chocolate chopped
  • 100 g milk or white chocolate chopped
  • sprinkles or flaked sea salt optional

Instructions

  • In a saucepan, melt the butter over medium heat. Continue cooking as it bubbles and splutters. A foam will develop on top. Once it goes silent and the foam disappears, you’ll see some brown bits at the bottom and smell a nuttiness, this means it’s done.
  • Remove from heat immediately once browned, and place in a heat-safe bowl. Make sure you have 135g browned butter. Add salt and stir. Place bowl in the fridge, allow to firm up for about an hour (when it’s time to make the dough, consistency should be thick like softened butter and color will be white on top with brown bits settling at the bottom)
    A bowl with a serving of layered dessert, reminiscent of tiramisu or cake, shows creamy and dark chocolate layers—much like the decadence of brown butter egg yolk chocolate chunk cookies. A spoon rests in the bowl beside a textured cloth on a light surface.
  • Preheat oven to 350.
  • Cream browned butter and sugars for 5 minutes until mix is very light in color.
