Description

Neon lime-green crispy rice “slime” bites made from a melted marshmallow binder, finished with a thin purple chocolate drizzle (plus optional candy eyes). No oven, no piping—just Halloween-ready texture and color.

4 tbsp (57 g) unsalted butter

Instructions

Set up your baking sheet: Line an 18×13-inch rimmed baking sheet with parchment paper. (Optional) Lightly spray the parchment with nonstick spray for easier release.
Melt the marshmallow binder: In a large microwave-safe bowl, melt the butter. Add the mini marshmallows and microwave in 30-second bursts, stirring each time, until completely smooth and fully melted. Stir in the vanilla extract.
Tint lime-green: Add lime-green gel food coloring a little at a time, stirring until evenly neon and glossy. You’re aiming for vivid lime-green with no dry white streaks.
Fold in crispy rice cereal: Add the crispy rice cereal and fold gently until every flake is coated. Work quickly so the mixture stays scoopable and glossy.
Shape irregular “slime” bites: Scoop about 2 tbsp of mixture per bite and drop onto the parchment. Use a spoon to gently mound and slightly “pull” the edges so the pieces look organic (not uniform bars). If the mixture sticks, lightly grease the spoon or dip it in warm water, then wipe.
Chill to set: Refrigerate uncovered for 20–30 minutes, until the bites feel firm and hold their shape when nudged.
Make the purple drizzle: Melt the purple candy melts in short microwave bursts (stir between bursts) until smooth. If needed for drizzling consistency, stir in 1–2 tsp (5–10 ml) neutral oil to help it ribbon off a spoon.
Drizzle + add eyes: Drizzle thin zigzags over each lime “slime” bite. If using candy eyes, place them while the drizzle is still slightly tacky.
Finish & set: Chill the tray for 10 minutes until the purple drizzle is fully set. Serve or package once firm.

Notes

For best visuals: keep the green mixture evenly tinted and glossy before folding in cereal. For best texture: fully melt the marshmallows before adding cereal, and don’t over-compress the scoops when shaping. If your kitchen is warm, chill the tray briefly before shaping again so the bites hold their mounds.
