Lightly grease a pizza pan and press the dough into the pan to form a thin and even cookie dough crust.

Remove from the oven and let it cool for 5 minutes.
While the cookie is still warm and soft cut out the shape of a skull.
Let the cookie cool completely.
In a medium bowl bring the cream cheese, yogurt, powdered sugar and vanilla together and whisk until smooth.
Place in the refrigerator for 30 minutes to thicken.

Get creative and use the fruit to make your own Day of the Dead sugar skull design.
Mix together the apricot preserves and water and pass the mixture through a sieve to remove lumps.
