Ready to be baked!!


  • Preheat oven to 325F degrees
  • Line 8 inch square pan with parchment paper and use butter to lightly grease the parchment paper.
  • In a saucepan, on low heat stir the butter until it is melted and brown bits should start to form with nutty scent.
  • Add the sugars to the butter and stir until combined.
  • Once the sugar and butter mixture is combined, pour it in the bowl for the standing mixer with whisk attachment and allow the mixture to cool.
  • In a medium size bowl, whisk together flour and baking powder and set on the side.
  • Make sure the butter and sugar mixture has cooled down a little before adding the eggs, vanilla extract and salt (otherwise you’ll end up cooking the eggs in the mixture).
    • Set the mixer on low speed while adding the ingredients.
  • Slowly add flour mixture to the mixing bowl and stir until just combined.
  • Approximately divide the batter in half and pour one half into in the pan.
  • Sprinkle the mini marshmallows and 1/2 cup of chopped chocolate on top of the first layer of batter.
  • Add the second layer of batter on top and finish with the other 1/2 cup of chopped chocolate chips.
  • Bake in oven for 20-25 minutes.
  • Once the brownie has cooled for about 10-15 minutes, then cut into the brownie for a warm, gooey treat!

Best way to start the weekend!
