To make the bows, use a silicone bow mold and dust the mold with cornstarch each time you make a fondant bow. The bows should be about 2"/5cm wide. Line a cookie sheet with parchment paper.
Pinch off about 1 tablespoon of orange fondant and press into the bow mold cavity.
Carefully remove from mold and set on the parchment-lined cookie sheet to air dry for a few hours (overnight or for 24 hours if possible). Repeat to make 6 bows total. TIP! Always make extra fondant decorations as backup!
Place the black candy melts into a microwave-safe bowl with the shortening. Melt according to package instructions, stirring to ensure even melting.
Spoon 3 tablespoons of the melted candy into a Mickey mold. Use a small spoon (or clean, unused brush) to coat all sides of the mold.
Place the mold into the fridge for about 10 minutes until set and hardened. Check to make sure that there are no areas around the base and sides that have been missed, and if there are, you can add another layer of melted candy as before and place it back in the fridge to set.
Repeat steps 5-6 to make 12 in total.
Carefully split the Halloween Oreos. Dip the top part (approximately 1/3) of a popsicle stick into melted candy and place onto the base of the Oreos and replace the top. Leave to set.
Place the Oreos and sticks into the mold and 2 mini Oreos in the ears. Cover with 3-4 tablespoons of melted black candy and tap the mold on the counter a few times to dispel any air bubbles. Place back into the fridge for another 10-15 minutes until set and hardened. Carefully remove from the mold.
To decorate, melt the (half bag) of white candy melts according to the package instructions then transfer to a disposable piping bag and cut off the tip.
Pipe spider webs on each of the Mickey-shaped treats. Place a bow on half of them to create Minnie. Serve when candy has set. Enjoy, and Happy Halloween!
