Equipment

Ingredients
 

  • 1 batch Rice Krispie Treats cut into 16 squares
  • 2 cups white candy melts melted, divided
  • ½ cup green candy melts melted
  • ½ cup black candy melts melted or black icing
  • ½ cup orange candy melts melted, or white candy melts + orange gel food coloring
  • ½ cup purple candy melts melted, or white candy melts + purple gel food coloring
  • Candy eyeballs about 40 total, mix sizes
  • 4 mini Oreo cookie halves use one wafer per spider
  • Black jimmies optional

Instructions
 

  • Ingredient amounts are listed to decorate 4 squares of each design. To make all 16 squares in one style, multiply the toppings for that design by 4.
  • Cut Rice Krispie Treats into 16 squares. Place on parchment-lined tray.
  • Melt the candy melts: Work on one design at a time, since each only needs 1–2 colors. Place wafers in a microwave-safe bowl and heat in 20–30 second bursts, stirring between each, until smooth. If the melts seize or thicken, stir in about 1 teaspoon coconut oil per cup of wafers to thin them back out.
  • Mummies (4): Spread melted white candy melts across the top of the Rice Krispies treat. Transfer some into a piping bag fitted with a Wilton #3 tip (or a zip-top bag with a tiny corner snipped). Pipe thin, uneven lines across each square to create bandages. Add 2 candy eyeballs before the melts set.
  • Frankensteins (4): Spread melted green candy melts to cover the top of Rice Krispies Treat. Transfer black melts into a piping bag with a Wilton #3 tip (or a zip-top bag with tiny corner snipped). Pipe jagged lines for hair. Add black jimmies for texture, if using. Press on candy eyeballs and draw a stitched smile with black icing or black melts
  • Spiders (4): Spread melted white candy melts over the top of Rice Krispies treat. Transfer melted black melts to a piping bag fitted with a Wilton #3 tip (or a zip-top bag with a tiny corner snipped). Pipe 3–4 straight lines down the treat. Connect with slightly curved lines between each section to form a web.Press on a mini Oreo wafer half, attach eyes with a dab of melts, then pipe 2-3 legs on each side extending onto the square.
  • Monster Eyes (4): Spread melted orange or purple candy melts (or tinted white melts) across the top of the Rice Krispies treat. Add assorted eyeball candy.
