Ingredients You’ll Need
Gather everything before you begin so that you can focus on the creative part, decorating.
- Oreo cookies, for that familiar chocolate filling and crisp texture (see Oreo details on their official site)
- Black candy melts (I recommend Wilton candy melts for their smooth finish)
- Neon green candy melts, available at craft stores or online
- Neon Rave sprinkles, or any brightly colored sprinkle mix
- An optional teaspoon of coconut oil, to thin candy melts if needed
Equipment Checklist
Having the right tools makes this recipe a breeze:
- Microwave-safe bowls or measuring cups
- Silicone spatula or heat-proof spoon
- Offset spatula or butter knife
- Parchment paper or silicone mat
- Baking sheet or tray
- Food-safe silicone mold
Step-By-Step Instructions
Prepare your workspace by lining a baking sheet with parchment paper or a silicone mat. Arrange the mold, bowls, and ingredients within easy reach to work efficiently.

Melt the neon “brains.” Place neon green candy melts in a microwave-safe bowl. Heat at 50% power for 2 minutes, then stir gently. Continue in 30-second bursts until smooth. If the mixture seems too thick, stir in a teaspoon of coconut oil to add shine and fluidity.

Fill the mold. Lightly mist the silicone mold with nonstick spray, if desired. Spoon melted green candy into each cavity, filling about three-quarters full. Tap on the counter to remove air bubbles, then freeze for five minutes to set.

Melt the black coating. In another bowl, melt the black candy melts at 50% power for 2 minutes, stirring, followed by 1-minute intervals until glossy and lump-free. Add a small amount of coconut oil if the mixture becomes too stiff.

Dip the Oreos. Holding one cookie by the edges, submerge it fully into the black coating. Lift and let excess drip off, then place on the prepared sheet. Work in batches of two to three to maintain a warm and smooth coating.
Assemble the Slashers. Remove the neon shapes from the freezer and unmold carefully. Press one brain onto each dipped Oreo while the coating is still wet.

Add sprinkles. Immediately scatter Neon Rave sprinkles around the “brain,” pressing lightly so they adhere evenly before the coating sets.
Set completely. Let treats rest at room temperature for at least 15 minutes, or refrigerate for 5–10 minutes if you’re eager to serve.

Recipe Tips and Tricks
- Gentle melting: Always use 50% microwave power and stir frequently to prevent scorching.
- Add thinning if needed: A teaspoon of coconut oil can help restore fluidity if it has melted and thickened too much.
- Small batches: Dip just two or three cookies at a time to keep your coating warm and silky.
- Mold mastery: Freeze until just set, overfreezing makes candy brittle and harder to unmold.
- Sprinkle strategy: Scatter soon after placing the “brain” to ensure even coverage and adherence.
- Cleanup hack: Dip your spatula in warm water and wipe dry before each use to avoid dried candy buildup.
Recipe Variations, Additions, and Substitutions
- Color swaps. Try electric blue, pastel pink, or bright orange candy melts to suit any party.
- Cookie alternatives. Use Golden Oreos, flavor-filled sandwich cookies, or even gluten-free options.
- Sprinkle mash-ups. Mix ghost, star, or bat-shaped sprinkles, edible glitter, or pearl sugar for an extra touch of flair.
- Flavor infusion. Stir in a drop of peppermint or coconut extract with your melts for a subtle twist.
- Dairy-free/vegan. Choose plant-based candy melts and vegan sprinkles; swap in vegan sandwich cookies.
- No mold? Pipe small neon candy dots on parchment, chill, then press onto dipped Oreos for an abstract effect.
- Texture boost. Press crushed nuts or cookie crumbs around the edge of each treat before the coating sets.

Frequently Asked Questions
Can I make these ahead of time?
Yes, assemble up to two days in advance. Store in a single layer in an airtight container at room temperature for best texture.
Will heat affect the candy coating?
Avoid direct sunlight and very warm spots. If treats soften, pop them in the fridge for a few minutes to firm up.
What if I don’t have a silicone mold?
Free-form neon candy circles on parchment, freeze until set, then adhere to dipped Oreos for a less detailed but equally fun look.
How long will they stay fresh?
Properly stored, these treats can be kept for up to three days at room temperature; refrigeration is recommended in very warm climates.
