Ingredients

  • 1/2 cup unsalted butter
  • 2 cups packed brown sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon salt
  • 1 teaspoon baking powder
  • 2 cups all-purpose flour
  • 1 cup Christmas M&Ms or your favorite color
  • 1/2 cup Christmas sprinkles use jimmies for best results

Instructions

  • Preheat oven to 350°F. Line a 9x13” pan with foil and spray well with cooking spray.
  • Mix butter and brown sugar with a stand or a hand mixer until crumbly. Mix in eggs and vanilla until smooth. Mix in salt, baking powder, then flour. Stir in M&Ms and sprinkles.
  • Spread in prepared pan. The mixture is wet so it’s best to spray your hands with cooking spray and then smooth the dough with your hands to get an even layer. Top with remaining mix-ins
  • Bake for about 22-25 minutes until they start to turn golden. Err on the side of under baked with these - they’ll finish baking as the cool and you don’t want them over baked. Slice into bars.
  • Store in an airtight container for up to 4 days or freeze for up to a month.

Notes

  • Use any color M&Ms and sprinkles for any holiday
  • Make sure to measure your flour and sugar correctly
  • Store in an airtight container and they'll last up to a week, making them perfect for shipping.
