Description

This is one of my all-time favorite recipes! Over the years I’ve changed it and tweaked it, and I will stand by the fact that this is the BEST Blondie Recipe ever!


Ingredients

Scale
  • 2 cups salted butter at room temperature
  • 1 1/2 cups granulated sugar
  • 1 1/2 cups light brown sugar, firmly packed
  • 4 large eggs
  • 1 tablespoon vanilla extract
  • 1 teaspoon coarse sea salt 
  • 1 teaspoon baking soda
  • 4 1/2 cups all purpose flour
  • 1 cup shredded sweetened coconut
  • 2 cups chocolate chunks
  • 1 1/2 cups mini marshmallows
  • optional – flaked sea salt to sprinkle on top

Instructions

  1. Preheat the oven to 350°F. Line a 15x10x1- inch pan with parchment paper and coat lightly with nonstick spray. Set aside. 
  2. In the bowl of your stand mixer fitted with the paddle attachment mix the butter, granulated sugar, and brown sugar together on medium-high speed for 2 minutes, until fluffy. Turn the mixer to medium and add in the eggs, one at a time, mixing well. Add in the vanilla, salt, and baking soda and mix until smooth and combined. 
  3. Turn the mixer to low and slowly add in flour, mixing until just combined. Don’t over-mix. 
  4. Stir in the coconut, chocolate chunks, and marshmallows. 
  5. Spread the batter evenly into the prepared pan and bake for 25 minutes. The edges will be golden and the center will just be set. Careful not to over-bake.
  6. Sprinkle with flaked sea salt if desired. Allow the bars to cool completely in the pan before cutting into bars.
