These festive cookie bars combine a soft, buttery dough with orange, green, and purple M&M's plus monster mash sprinkles. Baked in a 9x13 pan, they're perfect for parties and store well for up to 5 days.

Directions

Set your oven to 350°F.

In a stand mixer, combine the softened butter with both sugars. Beat on low for 1 minute until blended. Then add the eggs and vanilla, and mix on medium for another minute.

Stop the mixer. Add the flour, baking soda, and salt. Start on low, then increase to medium for 1 minute. Lower the speed to low and mix in 1-1/2 cups of the M&M's and the sprinkles until just combined.

Spray a 9x13-inch glass baking dish with cooking spray. Use a silicone spatula to transfer the dough into the dish and spread it evenly. Sprinkle the remaining 1/2 cup M&M's on top.

Bake for 30 to 35 minutes, until golden. Let the bars cool in the pan for 30 minutes before cutting. Store in an airtight container for up to 5 days.
