Chocolate Cereal: This is the crunchy, chocolatey base that holds everything together. It’s got that perfect cocoa flavor that balances out the sweetness of the marshmallows.
Mini Marshmallows: These gooey little bites are what bring it all together. As they melt, they coat the cereal, creating a chewy, marshmallowy goodness that sticks everything together in the most delightful way.
Butter: Butter adds richness to the mixture, helping everything come together smoothly and giving the bars that melt-in-your-mouth texture. It’s the secret ingredient for that indulgent flavor!
Vanilla Extract: A splash of vanilla extract enhances the flavor, adding a touch of warmth and depth to the marshmallow mixture. It’s the perfect finishing note!
Sprinkles or Chocolate Chips (optional): If you want to get a little extra fancy, top your hearts with colorful sprinkles or drizzle some melted chocolate chips on top. It’s the perfect way to make them pop even more!
(Note: the full ingredients list, including measurements, is provided in the recipe card directly below.)
Instructions
Let’s dive into how to make these deliciously simple treats:
Melt the Butter and Marshmallows: In a large saucepan, melt the butter over medium heat. Once the butter is melted, add the mini marshmallows and stir until they’re completely melted and smooth. Keep stirring to make sure it doesn’t burn!
Add Vanilla: Once your marshmallows are all melted and gooey, stir in the vanilla extract. It adds a lovely depth of flavor that balances out the sweetness of the marshmallows.
Mix in the Cereal: Remove the saucepan from heat and quickly add the chocolate cereal to the marshmallow mixture. Stir gently until the cereal is fully coated in the marshmallow goo. Don’t worry if it’s a little sticky—it’s part of the fun!
Shape the Hearts: Now comes the fun part! Lightly grease a heart-shaped cookie cutter or just grease your hands and press the mixture into the heart shapes. Place the shaped hearts onto parchment paper to set.
Cool and Set: Let the hearts cool at room temperature for about 30 minutes or until they’re set and firm. If you’re in a hurry, you can pop them into the fridge for 15 minutes to speed things up.
Enjoy! Once they’ve set, these marshmallow hearts are ready to enjoy! You can serve them as is, or add a little extra flair with sprinkles or melted chocolate drizzle.
