What Ingredients You Will Need

This recipe uses simple, easy-to-find ingredients to create the perfect balance of sweetness and crunch. You probably already have most of these in your pantry!

• Unsalted butter: Adds richness and helps bind everything together.
• Mini marshmallows: The key ingredient for that gooey, sticky texture (feel free to use regular-sized marshmallows if that’s what you have).
• Rice Krispies cereal: The classic crunch that makes this treat irresistible.
• Red food coloring: Gives the brains their creepy, realistic look.
• Cooking spray: Prevents sticking when shaping the brains.
• Optional decorations: Candy eyeballs, edible glitter, or gel icing for extra spooky flair.

If you’re looking for substitutions, you can use coconut oil instead of butter for a dairy-free option or swap out the food coloring for natural beet powder. The recipe is flexible, so feel free to get creative!

Equipment Needed

• Large saucepan: For melting the butter and marshmallows.
• Mixing spoon: A sturdy spoon to stir the sticky mixture.
• Measuring cups: For accurate ingredient proportions.
• Non-stick spray: To keep your hands and tools clean while shaping the brains.
• Wax paper: Great for setting the brains to cool without sticking.

If you don’t have wax paper, parchment paper works just as well. And for shaping the brains, you can use a silicone mold if you have one, though it’s not necessary—your hands work perfectly!

Preparation Method

1. Heat 3 tablespoons (43g) of unsalted butter in a large saucepan over medium heat until melted.
2. Add 10 ounces (283g) of mini marshmallows to the pan, stirring continuously until fully melted and smooth.
3. Remove the saucepan from heat and gently stir in 6 cups (150g) of Rice Krispies cereal, making sure the cereal is evenly coated.
4. Add a few drops of red food coloring and mix thoroughly until the color is evenly distributed. For a more realistic look, swirl the coloring lightly rather than fully mixing.
5. Let the mixture cool slightly, just enough to handle safely. Spray your hands with non-stick cooking spray to prevent sticking.
6. Shape the mixture into brain-like forms. To do this, form small oval shapes and use your fingers to create indentations and ridges for a realistic texture.
7. Place the shaped brains onto wax paper and allow them to cool and set for about 30 minutes.
8. Decorate as desired—add candy eyeballs, drizzle with red gel icing, or sprinkle with edible glitter for extra spooky vibes!

And there you have it—your very own batch of creepy, crunchy Rice Krispies Brains!

Cooking Tips & Techniques

• Don’t rush the melting process: Keep the heat on medium and stir constantly to avoid scorching the marshmallows.
• Work quickly: Once the mixture is ready, shape the brains while it’s still warm. It gets harder to mold as it cools.
• Use gloves if needed: If the mixture is too sticky, disposable gloves can make the shaping process easier.
• Be creative with decorations: Use gel icing to mimic veins or add gummy worms for an extra gross factor!
• Adjust food coloring: Start with a small amount and add more gradually for your desired level of creepiness.

Variations & Adaptations

• Gluten-Free Option: Use gluten-free puffed rice cereal to make this recipe suitable for those with gluten sensitivities.
• Seasonal Twist: Swap the red food coloring for green and make “alien brains” for a sci-fi party!
• Flavor Boost: Add a teaspoon of vanilla or almond extract to the marshmallow mixture for extra flavor.
• Dietary Adaptation: Replace butter with coconut oil and use vegan marshmallows for a plant-based option.
• Personal Touch: I’ve tried adding a pinch of cinnamon for a fall-inspired twist—it’s a subtle but fun addition!

Serving & Storage Suggestions

These brains are best served at room temperature, ideally within a few hours of preparation for maximum crunch. Arrange them on a spooky-themed platter or pair them with gummy worms for extra Halloween flair.

To store, place them in an airtight container at room temperature for up to 3 days. If you want to make them ahead, they can be frozen for up to a month—just thaw at room temperature before serving.

Reheating isn’t necessary, but if they lose their crunch, a quick zap in the microwave for a few seconds will revive their gooey texture!
