-Cream the butter, vanilla, and powder sugar until it looks light and creamy.
-If it doesn't cream add several drops of the heavy whipping cream until it creams.
-Add several drops of the green gel food coloring. Mix well to blend the colors.
-Test to see if the frosting can form and hold a stiff peak by taking a spoonful of frosting and turning the spoon upside down. If the frosting stays on the spoon it is ready if not then....
- Add more powder sugar 1/2 C at a time.... mix well.
-Test to make sure that the frosting can make and hold a stiff peak.
-If ready scoop the frosting into a pastry bag with a large star tip.
-Twist the open end of the pastry bag to push the frosting to the tip.
-Instead of holding the pastry bag and tip to the side hold it straight up pointing the tip down to the cupcake making the frosting look like grass.
-Start by frosting on the outside edge of the cupcake working to the center of the cupcake.
-You can add an candy pumpkin in the center of the grass patch (center of the frosting).
ENJOY!
