These heart-shaped Rice Krispie treats are fun, festive, and just as gooey and sweet as the classic version. I make them for Valentine’s Day, parties, or whenever I want a cute, no-bake treat that comes together fast and disappears even faster.
Why You’ll Love This Recipe
I love how quick and easy these are — just melt, mix, shape, and you’re done. The heart shape adds a special touch without any extra work. They’re soft, chewy, and perfect for decorating or gifting. Plus, they don’t need an oven, which makes cleanup a breeze.
Ingredients
(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
Rice Krispies cereal
mini marshmallows
unsalted butter
pinch of salt
vanilla extract (optional)
heart-shaped cookie cutter
sprinkles, melted chocolate, or candy melts (optional for decorating)
Directions
I melt the butter in a large pot over medium-low heat. Once melted, I stir in the marshmallows until completely smooth.
I add a pinch of salt and vanilla (if using), then remove the pot from the heat.
I quickly stir in the Rice Krispies until evenly coated.
I press the mixture into a buttered or parchment-lined 9×13 pan, pressing it down gently and evenly with a spatula or my hands (greased or covered with wax paper to avoid sticking).
I let it cool for about 15–20 minutes, then use a heart-shaped cookie cutter to cut out treats.
I decorate with sprinkles, melted chocolate, or candy melts if I want to make them extra festive.
Servings and timing
Servings: About 12–15 hearts (depending on cutter size) Prep time: 10 minutes Cool time: 20 minutes Total time: 30 minutes
Variations
I sometimes tint the marshmallow mixture with red or pink food coloring.
For chocolate lovers, I stir in mini chocolate chips or drizzle with dark chocolate.
I’ve made them with cocoa or fruity cereal for fun twists.
I use strawberry-flavored marshmallows when I can find them — great for Valentine’s Day.
Storage/Reheating
I store them in an airtight container at room temperature for up to 3 days. If they start to harden, I microwave one for a few seconds to soften it up. I don’t refrigerate them — that makes them too firm.
FAQs
Can I use large marshmallows?
Yes, I just cut them into smaller pieces or melt them slowly. Mini marshmallows melt more evenly, though.
How do I keep them soft?
I use fresh marshmallows and don’t overcook them. A little extra butter also keeps them chewy.
Can I make them ahead?
Definitely. I make them the night before and store them in a sealed container.
How do I cut clean shapes?
I press down firmly with a greased cookie cutter, then gently lift and push out the shape. A metal cutter works best.
Can kids help with these?
Yes! I let them help mix, shape, and decorate once it’s cool enough to handle.
Conclusion
These heart-shaped Rice Krispie treats are a sweet, simple way to make any day feel special. Whether I’m giving them as a gift or just making them for fun, they’re always a hit — chewy, cute, and full of nostalgic flavor.
These heart-shaped Rice Krispie treats are a fun and festive twist on the classic no-bake dessert. With gooey marshmallows, crispy cereal, and optional decorations, they’re perfect for holidays, parties, or sweet homemade gifts.
