Equipment

Ingredients

Cookie

  • 15.2 ounce box devil's food cake mix I recommend Duncan Hines
  • ½ cup butter, softened butter flavored shortening or oil also works
  • 2 eggs

Buttercream Frosting

  • ½ cup real butter
  • 2 cups powdered sugar
  • 1 teaspoon vanilla
  • 1 generous pinch salt
  • 1 + tablespoons milk or enough to reach desired consistency

Cream Cheese Frosting

  • 3 ounces cream cheese
  • 2 tablespoons butter
  • 2 cups powdered sugar
  • 1 pinch salt
  • 1 + tablespoons milk or enough to reach desired consistency

Instructions

  • Preheat oven to 350℉. Print off template guide.
    Tip: After your oven signals it's pre-heated, wait an extra 10-15 minutes if possible before placing food in.
  • Combine butter and eggs with dry cake mix (ignore all instructions on box) with a hand mixer or stand mixer until a cohesive dough forms. Butter should be very soft, it's even okay if you soften in the microwave and it's just a bit melted.
  • Divide dough into equal parts; I recommend a food scale to accurately divide.
  • Form each portion of dough into a round ball. Place template guide on a baking sheet. Place a sheet of parchment paper over the template guide. Pat dough evenly into circle shape following the guide for a 6" circle.
  • You are making 2 cookies. If you have a jumbo baking sheet you might be able to fit them both on, otherwise, use 2 separate cookie sheets or bake one and then bake the other. 
  • Bake each cookie for 12-15 minutes. You'll be looking for cracking on the edges and moving into the center of the cookie. This is a good signal the cookie is ready.  Remove pan from oven and let cool on the counter until cool enough to touch.  Slide parchment onto a cooling rack. Wait until cookie is completely cool before filling.
  • To prepare filling, choose buttercream or cream cheese icing and beat all ingredients until smooth.  Add milk one teaspoon at a time until frosting is fluffy and soft as desired.

Notes

  • Nutritional value is for the entire cookie, and was calculated using buttercream frosting.
  • Store in an airtight container at room temperature. Homemade cookies are safe to eat for a week or more when stored this way, but they will definitely have the best taste and texture the first couple days.
  • Feeling creative? Feel free to use any flavor of cake mix, or add different extracts to your frosting to really make this cookie your own!
