The following ingredients have 4 Servings
  • 1/2 cup (113g) unsalted butter, cold
  • 1/2 cup (95g) granulated sugar
  • 1/2 cup (110g) light brown sugar
  • 1 large egg
  • 1 tablespoon (15ml) pure vanilla extract
  • 1 cup (140g) all purpose flour
  • 1/4 cup (35g) vanilla cake mix, dry
  • 1 cup (80g) rolled oats
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1/2 cup (90g) white chocolate chips
  • 1/2 cup MnMs
  • 1/4 cup sprinkles
  • 3/4 cup (170g) unsalted butter, cold
  • 2 1/2 cups (325g) powdered sugar
  • 2 teaspoons (10ml) pure vanilla extract
  • 1 tablespoon (15ml) milk or heavy cream
  • Additional Sprinkles for garnish

Instruction

  • Preheat the oven to 350° F. Soften the cold butter in the microwave for 10-15 seconds. Combine the softened butter with the brown and granulated sugar. Beat on medium speed until well combined, 2-3 minutes.
  • Next add the egg and vanilla extract and continue beating until well incorporated.
  • In a separate bowl, combine the dry ingredients: flour, cake mix, oats, salt and baking soda. Stir to combine and slowly add the dry ingredients into the dough, mixing on low speed until dough starts to form.
  • Before the dough thickens, add the chocolate chips, MnMs and sprinkles. Beat a couple of times until they start to incorporate.
  • Line a baking sheet with parchment paper or a silicone baking sheet. Scoop the dough using a large cookie scoop and place on a sheet pan, 2 inches apart.
  • Bake for 13-15 minutes. The center of the cookie should be slightly under baked but not too gooey. Allow to cool on the baking sheet for 5-10 minutes before transferring to a wire rack to cool.
  • Cut the butter into smaller pieces. Using the paddle attachment, whip the butter for 5-7 minutes, scraping down the bowl occasionally, beating until the butter is very fluffy.
  • Add the powdered sugar, vanilla extract & heavy cream. Ensure the powdered sugar is well combined, then and whip for 3-4 minutes at high speed.
  • To assemble the cookies, find two cookies that are similar in size. Use a piping bag or Ziploc bag and cut of the tip off the bag, swirl the frosting on one side of the cookie. Place a second cookie on top and gently press down. Then you can roll the edges in additional sprinkles.
