- In a large bowl, cream together butter and sugars with a mixer for 1 minute. Add eggs and vanilla and mix.
- Then add flour, baking soda and salt and stir.
- Fold in M&M’s and chocolate chips and add dough to pan. Place a few extra M&M’s and chocolate chips on top.
- Bake for 30 to 35 minutes, or until top is barely golden brown. Allow to cool completely, then remove and slice.
TIP: For thinner M&M bars, use a 15×10″ pan instead.
Quick tips for M&M bars
- You can make these M&M bars anytime throughout the year! Just pick up colored M&M’s that match the occasion or holiday.
- Don’t have M&M’s on hand? Replace M&M’s with 1 cup chocolate chips.
- To top with glaze, combine 1 cup powdered sugar and 1 tablespoon of milk. Drizzle over M&M bars once cooled.
- Make sure to line your baking pan with foil! This really helps the Christmas cookie bars to cook evenly.
- M&M bars will keep at room temperature stored in an airtight container for about 3 days, or about 5 days in the fridge.
- To freeze, wrap in foil then place in an airtight container. They will last in the freezer for a couple of months.

Enjoy!!
I was skeptical about covering the pan in foil, but they did bake up evenly and then removing the bars for cutting was a breeze. Easy clean-up too. They looked nice and tasted great! I like thick bars so I can sink my teeth into them, so I used the 9 x 13″ pan. I may try thinner bars next using the bigger and flatter pan for comparison sake and a larger yield.
Your comment made my day! I’m so glad you enjoyed them Cathy! :) The foil trick has been such a lifesaver for all my bar recipes.
My first attempt and they turned out great ! I will be making these again !
So glad you enjoyed them! :)
