  • 1 box white cake mix dry ingredients only
  • 1/2 cup vegetable oil
  • 2 large eggs
  • Green gel food colouring (I used Wilton Leaf Green)
  • Red gel food colouring (I used a mix of Wilton Rose and Wilton Christmas Red gel colors)
  • 1 edible marker pen black
  • Skittles or m&m’s for the monster eyes


  • In a bowl mix together the white cake mix, oil and eggs until combined. Divide the batter equally into two separate bowls.
  • Add gel food colouring to get the desired colour you want (I used green and red gel food colouring - also see notes).
  • Place in the fridge for about 45 minutes.
  • Meanwhile, using your edible marker pen, draw ‘eyes’ on the skittles or m&m’s. I used different colours for fun. Set aside.
  • Once ready to bake the cookies, line a baking tray with a silicone mat or baking parchment.
  • Scoop out the cookie dough and bake at 350 F / 175 C for 10-12 minutes. The cookies are ready to be taken out of the oven when the edges are slightly firm but the middle is still soft and squishy (also see notes).
  • As soon as you take them out of the oven, press in the ‘eyes’.
  • Once the cookies have cooled you can draw scary or silly faces on the cookies with the edible marker pen.
  • These cookies can be stored unto 4-5 days in an airtight container.
