Ingredients Equipment Method Notes

Ingredients
  

  • 1 1/2 cups All-Purpose Flour
  • 1/2 cup Unsalted Butter, softened to room temperature
  • 1/2 cup Light Brown Sugar, packed
  • 1/4 cup Granulated Sugar
  • 1 teaspoon Pure Vanilla Extract
  • 1/4 teaspoon Salt
  • 2-3 tablespoons Milk or Heavy Cream
  • 1/2 cup Mini Chocolate Chips
  • 1 cup Lucky Charms Marshmallows, divided 1/2 cup for dough, 1/2 cup for topping
  • 1 cup White Chocolate Chips

Equipment

  • 8x8 inch baking pan
  • Parchment paper
  • Baking sheet
  • Oven (for heat-treating flour)
  • Stand mixer or electric hand mixer
  • Large mixing bowl
  • Rubber spatula
  • Microwave-safe bowl
  • Sifter or fine mesh sieve

Method
 

  1. Preheat your oven to 350°F (175°C). Spread the all-purpose flour onto a baking sheet lined with parchment paper.
  2. Bake the flour for 5 to 7 minutes until it reaches an internal temperature of 160°F (71°C) to kill bacteria. Let the flour cool completely.
  3. Once cooled, sift the flour to remove any lumps created during the heating process.
  4. In a large mixing bowl or stand mixer, cream together the softened butter, brown sugar, and granulated sugar on medium-high speed for 2 to 3 minutes until pale and fluffy.
  5. Add the vanilla extract and salt to the butter mixture and mix until combined.
  6. Turn the mixer to low speed and gradually add the cooled, heat-treated flour. The mixture will look crumbly.
  7. Slowly drizzle in the milk or heavy cream, one tablespoon at a time, mixing until the dough comes together and holds its shape. Adjust with slightly more milk if too dry, or flour if too wet.
  8. Stop the mixer and use a rubber spatula to gently fold in the mini chocolate chips and 1/2 cup of the Lucky Charms marshmallows.
  9. Line an 8x8 inch square baking pan with parchment paper, leaving an overhang on the sides.
  10. Transfer the dough into the pan and press it down firmly into an even, flat layer.
  11. Place the white chocolate chips in a microwave-safe bowl. Melt in 30-second intervals, stirring in between, until completely smooth.
  12. Pour the melted white chocolate over the cookie dough base and spread to the edges.
  13. Immediately sprinkle the remaining 1/2 cup of Lucky Charms marshmallows on top before the chocolate sets.
  14. Refrigerate the pan for at least 1 hour until the chocolate is firm and the dough is chilled.
  15. Remove from the pan using the parchment overhang and slice into bars while cold for clean cuts.

Notes

Safety First: Do not skip heat-treating the flour; raw flour can contain harmful bacteria. Storage: Store these bars in an airtight container in the refrigerator for up to 1 week. Variations: You can substitute gluten-free flour (heat-treated) or use dairy-free butter and chips for dietary restrictions.
