Ingredients
  

Instructions
 

  • Preheat oven to 350 degrees. Lightly spray a 9x13" pan with non-stick baking spray. Set aside.
  • In a large mixing bowl using a hand or stand mixer, cream together the room temperature butter, granulated sugar and brown sugar. Add in the vanilla and eggs, mix together until smooth and fluffy.
  • In a separate bowl, whisk together the flour, baking soda, and salt.
  • Gradually add the dry ingredients to the wet ingredients, stopping the mixer occasionally to scrape down the sides of the bowl with a rubber scraper. Once all the ingredients are combine, the dough will be thick and smooth.
  • Using a rubber scraper or wooden spoon, fold in the M&M candies, chocolate chips and white chocolate chips to the batter. Mix until just combined.
  • Spread the batter evenly into the bottom of the prepared 9 x 13" pan.
  • Bake at 350 degrees for 35 minutes or until the bars are golden brown and just set in the middle. Be sure to not over-bake.
  • Remove from oven and let cool to room temperature before cutting into squares.

Notes

Cutting the bars: this recipe will make 24 squares/bars. Cut the bars 4 x 6(long side). For smaller squares you could also cut 5 x 6 (long side). This will render 30 bars.
Storage: once the bars have cooled completely to room temperature, store in an airtight container at room temperature. The bars will keep for up to 7 days at room temperature. (No need to refrigerate.)
Freezing: these bars can be frozen. Store the cooled bars in a freezer bag or freezer container. You can wrap each bar individually or freeze the entire batch together. Frozen, the bars will keep for up to 3 months. Thaw the bars at room temperature.
