M&M Christmas Cookie Bars
One of my favorite things to make are these Christmas M&M Cookie Bars because they are so easy and they’re loaded with Christmas colors and cheer. They have soft and chewy centers with crispy edges and then topped with more white chocolate, M&Ms, and sprinkles.
Everyone will love this easy dessert because they taste like cake in an cookie bar form. Perfect for serving on cookie trays, gifting to friends, teachers, neighbors, and for leaving out on Santa’s cookie plate with a glass of milk :).

Why You’ll Love These holiday cookie bars
Key ingredients
- Vanilla boxed cake mix: We use one box of white cake mix. Betty Crocker, Pillsbury and Duncan Hines are all great cake mix options.
- Large eggs: Room temperature eggs are always best.
- Butter: Alternatively, any type of neutral oil will work such as canola oil or vegetable oil.
- Festive sprinkles: We add sprinkles for fun. You can use any sprinkle colors and use more or less than what the recipe calls for.
- M&M candies: The star ingredient! I love using the festive red and green M&M colors to make these Christmas treats. You can also use Mini M&M candies if you prefer.
- White chocolate chips: We add chocolate chips in the cookie batter and drizzle the baked cookie bars with melted chocolate. Double white chocolate goodness!
how to make christmas cookie bars
Mix ingredients together: Preheat the oven to 350 degrees F and line a 9×13 inch glass baking pan dish with parchment paper. In a large bowl with an electric hand mixer or wooden spoon, combine the cake mix, melted butter, and eggs together.
Add in chocolate, candies, and sprinkles: Stir in 3/4 cup of white chocolate chips, 3/4 cup M&Ms, 1/4 cup of sprinkles.
Add dough to baking dish: Spoon the dough into the prepared pan and spread the dough evenly in the pan (the dough will be sticky). Bake in the oven for 20 minutes or until the edges are a light golden brown.
Cool cookie bar: Remove from the oven and let cool in the baking dish for 15 minutes. After 15 minutes, remove the parchment paper from the baking dish and let the cookie bar cool on a cooling rack for 30 minutes. On a cutting board, cut the cookie bar into 12 pieces.
Melt white chocolate: After the cookie bars are cooled, heat the remaining white chocolate in the microwave in 30 second increments until melted.
Add toppings and let cool: Separate the cookie bars a little and then drizzle the white chocolate over the cookie dough bars using a fork. Top with remaining M&M candies, white chocolate chips, and sprinkles. Let cool completely.
tips & variations
- Any holiday or celebration: Bake these Cake Mix M&M Cookies for different holidays or occasion by swapping the M&M and sprinkle colors.
- Chocolate Cake Mix Cookies: Use chocolate cake mix and add in milk or dark chocolate chips to make them chocolatey.
- Feed a crowd: Cut into 24 smaller bars instead of 12 if you want to yield more. Perfect for parties!
- Gluten-Free Cookies: Use gluten-free cake mix to make these cookies gluten-free.
- For best results, refrigerate the cookie bars for a few minutes before cutting the bars to get perfect cut bars.
- Favorite Mix-Ins and Add-Ins: Milk chocolate chips, mini chocolate chips, chopped nuts, mini marshmallows, crushed pretzels, and chopped Golden Oreos or regular Oreos, peanut butter chips, or butterscotch chips.
- Use a sharp knife or pizza cutter to cut the cooled cookie bars.
leftovers & storage
To-store: Store these Christmas M&M Cookie Bars at room temperature in an air-tight container or large ziplock bag. You could also cover the a dish with plastic wrap. They will stay fresh for 7 days. They will still be ok to eat after 7 days but they may start to get crumbly and stale.
To-freeze: Allow the baked cookie bars to cool completely. Place the cut bars on a baking sheet in the freezer for 30 minutes to flash freeze or harden. Once hard, place the cookies in a large freezer bag or stack in an airtight container. Store for up to 3 months- when ready to serve, remove from the freezer to thaw until softened.
