Equipment

  • Light Colored Saucepan - for browning butter
  • 8x8 Inch (20cm) Metal Baking Pan
  • Mixing Bowls
  • Whisk/Silicone Spatula
  • Measuring Cups/Spoons

INGREDIENTS

  • ¾ Cup (170g) Unsalted Butter browned
  • 1 ¼ Cup (250g) Light Brown Sugar packed
  • 1 Whole Large Egg + 1 Yolk
  • 1 ½ Teaspoons Vanilla Paste or Extract
  • 1 ½ Cup (180g) All-Purpose Flour
  • ½ Teaspoon Fine Sea Salt
  • ½ Cup (96g) M&M's (plus more for topping)
  • ½ Cup (86g) Dark or Semi-Sweet Chocolate Chips
  • Heart Sprinkles (optional)

Instructions
 

  • Preheat Oven - Position a rack in the center of the oven and preheat it to 350ºF (180ºC). Butter and line an 8x8 inch (20cm) metal pan with parchment paper, leaving an overhang for easy removal.
  • Brown Butter - In a light colored pan and over medium-low heat, add cubed butter. Swirl the pan and keep the butter moving around constantly. As the butter melts, it will foam and sizzle and gradually start to brown and deepen in color. You'll also notice a nutty aroma and tiny brown specks at the bottom of the pan. The whole process should take about 10 minutes or so. Be careful not to burn it.
    ¾ Cup (170g) Unsalted Butter
  • Combine Brown Butter & Sugar - Once browned, immediately pour the butter into a large mixing bowl and scrape in all the tiny brown bits from the bottom of the pan. Add brown butter and using a whisk, whisk vigorously for a minute until well combined.
    1 ¼ Cup (250g) Light Brown Sugar
  • Add Egg, Yolk & Vanilla - Add 1 whole egg, 1 yolk and vanilla, and whisk until the mixture is well combined.
    1 Whole Large Egg + 1 Yolk
    1 ½ Teaspoons Vanilla Paste or Extract
  • Add Dry Ingredients - Sift in the flour and salt, and switching a silicone spatula, fold until nearly combined.
    1 ½ Cup (180g) All-Purpose Flour
    ½ Teaspoon Fine Sea Salt
  • Add Chocolate - Next, fold m&m's and chocolate chips into the blondie batter until even incorporated. Do not overmix.
    ½ Cup (96g) M&M's (plus more for topping)
    ½ Cup (86g) Dark or Semi-Sweet Chocolate Chips
  • Using an offset spatula, evenly spread the blondie batter into your prepared pan. If desired, top with a handful of m&m's and sprinkles.
  • Bake - Bake in your preheated oven for 25 to 30 minutes. It's ready when the edges are golden and the middle is set. Mine took 25 minutes. Do not overbake. 
  • Cool - Set on a wire rack and allow to cool in the pan for at least 30 minutes. Then remove from the pan and set on the wire rack to cool completely at room temperature. If you're in a hurry, you can set it in the fridge for an about an hour. Slice into 9 or 16 pieces. Serve and enjoy!

Notes

Metal Baking Pan - This recipe has only been tested with a metal baking pan. If you are using a glass or ceramic baking pan, it may take longer to bake.
Do not overbake - For gooey fudgy blondies, always err on the side of underbaking them. Mine took 25 minutes.
Storage - Store blondies in an airtight container on the counter for up to 4 days or in the fridge for up to a week. You can also store in the freezer for up to 2 months. Allow to thaw at room temperature before serving.
