Ingredients

Scale

For the Cookie Dough Base:

  • 1/2 cup (1 stick) unsalted butter (softened)
  • 3/4 cup brown sugar (packed)
  • 1/4 cup granulated sugar
  • 1/4 cup milk (or heavy cream)
  • 1 tsp vanilla extract
  • 1/2 tsp salt
  • 1 3/4 cups all-purpose flour (heat-treated*)
  • 1/2 cup mini chocolate chips
  • 3/4 cup M&M candies

For the Chocolate Topping:

  • 1 cup semisweet chocolate chips
  • 1 tbsp coconut oil or butter
  • 1/4 cup M&Ms (for garnish)



Instructions

Step 1: Heat-Treat the Flour (Important for food safety!)

  1. Preheat oven to 350°F (175°C). Spread flour on a baking sheet and bake for 5 minutes. Let cool completely before using. (Alternatively, microwave flour in 30-second intervals, stirring between each, until it reaches 165°F.)

Step 2: Make the Cookie Dough

  1. In a large bowl, beat together butter, brown sugar, and granulated sugar until smooth.
  2. Mix in milk and vanilla extract until well combined.
  3. Gradually add heat-treated flour and salt, stirring until a dough forms.
  4. Fold in mini chocolate chips and M&Ms.

Step 3: Press into a Pan

  1. Line an 8×8-inch baking pan with parchment paper.
  2. Press the cookie dough evenly into the pan.

Step 4: Add the Chocolate Topping

  1. In a microwave-safe bowl, melt chocolate chips and coconut oil in 30-second intervals, stirring until smooth.
  2. Pour over the cookie dough and spread evenly.
  3. Sprinkle with extra M&Ms for a fun, colorful touch.

Step 5: Chill & Slice

  1. Refrigerate for 1-2 hours, or until firm.
  2. Slice into 12-16 bars and serve!

Notes

  • Storage: Keep in an airtight container in the fridge for up to 5 days, or freeze for up to 2 months.
  • Peanut Butter Twist: Swap 1/4 cup of butter for peanut butter for a nutty flavor!
  • Gluten-Free Option: Use gluten-free flour and heat-treat as usual.
