Ingredients

Scale

Wet Ingredients

  • 1/2 cup softened butter
  • 1/2 cup brown sugar
  • 1/4 cup white sugar
  • 1 tsp vanilla extract
  • 1 egg

Dry Ingredients

  • 1 cup all-purpose flour
  • 1/3 tsp baking soda
  • 1/3 tsp salt

Add-ins

  • 1/2 cup chocolate chips
  • 1/2 cup M&Ms (reserve some for topping)

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) to prepare for baking the cookie bars.
  2. Cream Butter and Sugars: In a mixing bowl, combine the softened butter, brown sugar, and white sugar. Beat the mixture until it becomes smooth and creamy.
  3. Add Vanilla and Egg: Incorporate the vanilla extract and egg into the creamed mixture by beating thoroughly until fully blended.
  4. Combine Dry Ingredients: In a separate bowl, whisk together the flour, baking soda, and salt to ensure even distribution.
  5. Mix Dry into Wet: Gradually add the dry ingredients into the wet mixture, beating until completely combined into a smooth dough.
  6. Fold in Chocolate and M&Ms: Stir in the chocolate chips and most of the M&Ms, keeping some M&Ms aside for topping the bars.
  7. Prepare Pan: Spread the cookie dough evenly into an 8×6 inch or 9×7 inch baking pan for an even thickness.
  8. Add Topping: Sprinkle the reserved M&Ms evenly over the top of the dough to create a colorful finish.
  9. Bake: Place the pan in the preheated oven and bake for 18 to 20 minutes or until the surface turns golden brown.
  10. Cool and Slice: Allow the cookie bars to cool completely in the pan before slicing them into squares for serving.

Notes

  • Make sure the butter is softened to room temperature for easy creaming with sugars.
  • Do not overbake; the bars should be golden but still soft for a chewy texture.
  • You can substitute M&Ms with other colorful candies or chocolate pieces if desired.
  • Allow bars to cool fully to set properly and prevent them from falling apart when cut.
  • Store cookie bars in an airtight container at room temperature for up to 3 days.
