Ingredients
  

  • 1 large egg
  • 1/3 cup (65g) granulated sugar
  • 2/3 cup (120g) brown sugar, packed
  • 1/2 cup (113g) unsalted butter
  • 2 tsp vanilla extract
  • 1 cup (120g) AP flour
  • 2 tbsp (18g) cornstarch
  • 1/2 tsp salt
  • 1/3 cup (55g) sprinkles

Instructions
 

  • Line or spray an 8x8 pan. Preheat the oven to 350℉.
  • In the bowl of a stand mixer or large mixing bowl, add your egg and sugars. Whisk at medium-high speed for 3-4 minutes, until paler in colour, glossy and ribbony looking. While that mixes, add your butter to a heatproof bowl.
  • Heat the butter in the microwave in 20 second increments until melted. Stir in vanilla extract. Pour the butter mixture slowly into the egg mixture while whisking at slow speed.
  • Once fully added, whisk at medium-high speed again for 10 seconds. Add in the flour, cornstarch, salt and sprinkles. Using a spatula, gently fold together until just combined.
  • Pour the batter in the lined pan, using the spatula to spread it evenly. Bake for 23-25 minutes or until a toothpick inserted 2/3 of the way in from the edge of the pan comes out with moist crumbs. Don't overbake or they'll lose their fudgy texture.
  • Allow to cool in the pan for 15 minutes before transferring to a wire rack to fully cool. Cut into desired amount of squares and store in an airtight container for up to 3 days and enjoy!
