Pre heat oven to 180 degrees Celsius and place patty pans into a 2 x 12 hole pans.
In a medium bowl, sift the flour, baking powder and bi-carb soda. In a separate bowl, combine eggs, icing sugar, oil, orange essence and food colour. Mix well.
Add the dry ingredients to wet ingredients in two batches, mixing well in between. Add the orange juice and the zest. Mix well by hand.
Fill patty pans to 1/2 to 3/4 full and bake for 20 minutes. Let cool on a wire rack.
To make the frosting: In a small mixing bowl, cream the butter until light and fluffy. Beat in the icing sugar, orange zest and extract. Add enough orange juice to achieve a frosting consistency (a little on the firm side so that it holds the weight of another cupcake when assembling your monsters)
Spread frosting on top of cupcake and then top with another upside-down cupcake. Add the tic tacs for teeth and candy eyes, using a little extra frosting as glue if required. Insert chocolate stick through the top cupcake.
Happy Halloween. Enjoy!
