Valentine Rice Krispie Treats: These Valentine’s Day rice krispie treats are made with your favorite heart-shaped cookie cutters or silicone molds and decorated with sprinkles and piped icing.
Although you can make heart shapes with rice krispies treats any time of year, it’s possibly our favorite, no-bake Valentine’s Day dessert idea and a fun idea for the holiday!

Ingredients
These heart rice krispie treats only require 4 ingredients! (Unless you want to try our rice krispie treats made with milk.) However, if you prefer to decorate with sprinkles, icing, etc. you’ll need those items as well! To make the Valentine’s rice crispy treats that you see here, we only used sprinkles and store-bought piped icing!

- 3 tablespoons butter
- 4 cups mini marshmallows
- 6 cups rice krispie cereal
- 1 tablespoon vanilla extract
- sprinkles, if desired
- icing, if desired
- non-stick cooking spray, optional
See the recipe card toward the end of this post for ingredients and instructions all in one place for these Valentine treats
Instructions
- First, melt butter in large saucepan on low heat.
- Next, pour in marshmallow and stir to combine, allowing the low-heat to gently melt the marshmallows. Stir often.


- Once marshmallows have melted, pour in vanilla extract and stir to combine.

- Next, pour in rice krispies cereal and stir to combine.


- Now it’s time to shape the marshmallow mixture in to hearts. (You can use a heart-shaped mold or cookie cutters like I used in our heart sugar cookies. See tips below.)

- If using a silicone mold, simply dish out amount of rice krispy mixture and gently press mixture in to mold. If using cookie cutters, you can spray them with cookie spray so the treats do not stick – then place cookie cutter on parchment paper or wax paper and fill cookie cutter with treats. Remove and repeat until mixture is gone.
- NOTE: if decorating treats with sprinkles, it’s best to pour sprinkles on to the sweet treats before they harden, so sprinkles will secure in to the marshamallow texture for the perfect treat.


Icing Tube
To keep things super simple, we used Cake Craft Icing Tube’s, in pink and red. We found that these were really easy to use and worked well on these fun treats, so you don’t even have to use a piping bag.
To use them, you simply attach a piping tip (I used a #3 piping tip)to the tube and can start decorating!
TIP: Feel free to wait until the rice krispie treat hearts have hardened before applying icing if you prefer.

Substitutions
Side Note: I bought this heart-shaped silicone mold to use for these rice krispy treats and found that it was my favorite way to make them! However, heart-shaped cookie cutters work just fine too!
You can use other items to decorate these treats if you prefer. Such as:
- melted chocolate drizzle (white chocolate chips, milk chocolate chips, etc.)
- dip hearts in melted chocolate
- red or pink candy melts
Variations
If you want to get super creative and have fun with the rice crispy treat hearts, you can mix in items like we did with our some of our favorite recipes caramel rice krispie treats and cookies & cream treats!

Storage
Store the Valentine’s rice krispie treats in an airtight container at room temperature for up to 2-3 days for freshness. (You can enjoy them after 2-3 days but the longer they sit, the harder they can get.)

Top tip
It’s best to make them the day of, so they’re as soft as possible. However, you can make them a day in advance, just make sure to store them properly.
Spraying hands with cooking spray before shaping or pressing in to a pan can help prevent marshmallow treats from sticking to your hand. Or, place hand in small plastic baggie, then spray with cooking spray or spread small amount butter on to bag, then press. This way the treats won’t stick to the bag and your hand remains clean.
When pressing down on rice krispie treats to mold them, don’t press super hard, as this can make your treats hard. Gently press, to shape them for a gooier, treat.
