Cookie Bars:

  • 1 cup butter melted
  • 1 cup granulated sugar
  • 1 cup brown sugar packed
  • 2 eggs
  • 1 teaspoon vanilla extract
  • 1 teaspoon baking powder
  • 1 teaspoon baking soda
  • 1 teaspoon salt
  • 1 ½ cups flour measured correctly
  • 2 cups sweetened shredded coconut
  • 2 cups old fashioned oats
  • 2-3 cups of candy/mix-ins

Mix-in Ideas:

  • Reese’s
  • Snickers
  • M&Ms
  • Twix
  • Heath bar
  • Chocolate chips (white chocolate, peanut butter chips, dark chocolate, semisweet, butterscotch)
  • Peanuts
  • Almonds


  • Preheat oven to 350 degrees Fahrenheit. In a large mixing bowl combine melted butter, 1 cup brown sugar, and granulated sugar. Once combined, add in eggs, and vanilla.
  • Stir in flour, baking soda, and baking powder until just combined. Then stir in shredded coconut and oats, and mix ins (I reserved some mix-ins to sprinkle on top).
  • Spread batter into a greased 9x13 pan until evenly distributed. Bake for 23-25 minutes, Cool completely before serving.


Substitute the coconut for oats. You can make these cookies bars strictly with oatmeal. Just replace your 2 cups of shredded coconut with an additional 1½ cups old-fashioned oats.
Replace the candy. You can replace the candy with chocolate chips.
