These Watermelon Cake Mix Cookie Sandwiches look like summer! Strawberry cake mix cookies are studded with chocolate chips, filled with buttercream frosting, and rolled in green sugar.



  • 1 box strawberry cake mix
  • 2 eggs
  • 1/2 cup vegetable oil
  • 1/2 cup mini chocolate chips
  • 1/4 cup butter, at room temperature
  • 2 cups powdered sugar
  • 1/8 cup milk
  • 1/2 teaspoon vanilla
  • green colored sugar


  1. Preheat the oven to 350F. In a bowl, mix together the cake mix, eggs and vegetable oil until combined. Mix in the chocolate chips.
  2. Drop by tablespoonfuls onto an ungreased cookie sheet. Bake in the preheated oven for 8-10 minutes. Cool completely.
  3. In another bowl, beat the butter until smooth. Gradually add in the powdered sugar. Add the milk and the vanilla and mix until smooth.
  4. Turn half of the cookies upside down. Using an offset spatula or a piping bag, add frosting to the bottom of the cookies. Top with another cookie to make a sandwich. Roll the edges of the frosting in the colored sugar.
