Ingredients
- Multigrain or crispy rice cereal: six cups give you sturdy, light crunch that soaks up the marshmallow without getting soggy look for fresh, airy cereal for best texture
- Mini marshmallows: four cups melt smoothly and give ideal fluffiness choose fresh soft marshmallows so they melt evenly
- Unsalted butter: three tablespoons create richness make sure it smells sweet and is not overly soft or greasy for best taste
- Vanilla extract: adds warm flavor dimension to all the sweetness pick pure vanilla for depth
- Candy-coated chocolates: adds bursts of color and a chocolatey bite pick vibrant ones for extra fun and double check for allergy information if sharing
- Mini chocolate chips: optional make the bars extra decadent look for dark mini chips for deeper chocolate taste
- Candy eyes: make these monster-themed and irresistible try to find ones with crisp definition so they really pop
Instructions
- Prepare the Pan:
- Lightly grease a 9 by 13 inch baking pan or line it smoothly with parchment paper. This makes sure the cooled bars lift out without sticking or crumbling. A well-prepared pan means easy slicing and neat squares.
- Melt the Marshmallows:
- Place unsalted butter in a large heavy bottomed saucepan over medium low heat. Allow the butter to fully melt but not brown—watch for a soft golden color and no bubbling. Add mini marshmallows and stir patiently with a sturdy spatula. Use a gentle folding motion, scraping the bottom until everything is completely melted and creamy. The key to great texture is constant stirring so nothing scorches.
- Blend in Vanilla:
- Once the marshmallow mixture looks glossy and no lumps remain, take the pan off heat. Immediately pour in the vanilla extract and stir until evenly distributed. This helps lock in flavor before the mixture starts to set.
- Mix in the Cereal:
- Quickly add all your cereal to the hot mixture. Work swiftly but gently to coat every kernel with marshmallow. Use a folding movement rather than mashing to preserve crunch. The marshmallow should thread through the cereal with no dry patches.
- Stir in Chocolates and Chips:
- Add half of the candy-coated chocolates and half the mini chocolate chips to the cereal mixture. Fold them in gently so they are spread throughout the base. Mixing while the cereal is still warm helps the candies adhere without melting fully.
- Press into the Pan:
- Transfer the sticky mixture to your prepared pan. Use a buttered spatula or a piece of wax paper to press it evenly, starting from the center and working outwards. The surface should be firm and flat but not packed down hard—the softer you press, the easier the bars will be to eat and slice later.
- Decorate the Top:
- Sprinkle the remaining candy-coated chocolates, mini chocolate chips, and candy eyes over the top. Press each piece in lightly so they adhere but keep their shape. If using candy eyes, space them randomly for a monster effect. Adding sprinkles or a drizzle of melted chocolate here works wonderfully too.
- Cool and Slice:
- Let the pan sit uncovered at room temperature for about thirty minutes until fully cool. The bars will firm up but stay chewy. Lift them out using the parchment edges or just cut gently in the pan into twelve neat bars.
Save It These bars are high nostalgia for me because my grandma used to let us decorate each one however we wanted. She always saved a few extra candies for whoever helped wash up. The best part is how the candy eyes give every bar its own personality.
Storage Tips
Store in an airtight container at room temperature for up to three days. If you need to keep them longer, wrap tightly and freeze for up to one month. They hold up best in cool dry spots. Avoid refrigerating as it can sometimes harden the marshmallows.
Ingredient Substitutions
You can swap in cornflakes, puffed rice, or use gluten free cereal if allergies are a concern. Margarine can stand in for butter in dairy free variations. Dried fruit, nuts, or different colored candies all make fun swaps for the mix ins and toppers for different occasions.
