Ingredients and Substitutions Notes

You'll need to gather just a few simple ingredients to make heart Rice Krispie treats…

Salted Butter – Use real butter, not margarine. And use salted butter so you get that extra boost of flavor from the salt.
Vanilla Extract – Most Rice Krispie treat recipes don't call for vanilla, but I really love the flavor it gives to these wonderfully chewy treats.
Sea Salt – Don't leave this out; it really helps give a boost of flavor to these heart shaped Rice Krispie treats.
Mini Marshmallows – You can use big marshmallows or marshmallow cream (though ingredient amounts differ), but mini marshmallows melt more quickly and efficiently.
Rice Krispies cereal – You can use any brand of crisp rice cereal or Rice Krispie cereal you want; I prefer to use either Malt-O-Meal Crispy Rice or Millville (from Aldi) because they're gluten-free.
– These colorful M&M's give an extra festive touch to your Valentine treats.
Valentine Sprinkles – Feel free to use whatever sprinkles you can find, the tinier the better, because you don't want to take away from the flavor of your treats.

How to Make Valentine Rice Krispie Treats

First things first, you'll need to make the treats.

How to Make Rice Crispy Treats

Melt butter in a large saucepan or Dutch oven over medium-low heat.
Then stir in the vanilla extract and salt.
Add the mini marshmallows, and stir 'til they melt into a smooth, creamy mixture.
Next begin to stir in the Rice Krispies cereal, partially stirring them in to your marshmallows.

Now for the best part… Stir in the M&M's candies, and finish mixing everything together.
Wet your hands with water; then spread the Rice Krispies cereal mixture into a greased 9×13 baking pan. (Note: Sometimes I’ll use a regularcake pan, but if I know I’m cutting out shapes, I’ll use my more shallowbrownie pan. The brownie pan really allows me to get in with the cookie cutter and not have to fight with the sides of the pan. OR you can also go the route of sticking parchment paper or wax paper in your pan, grease it with non-stick cooking spray, and spread the mixture on top of the paper. That way when it comes time to cut out the heart shaped treats, you can just pull the whole thing, by the paper, out of the pan, then cut.)
Be sure to add the sprinkles right away, so they'll stick to the warm marshmallow treats. If you wait too long, the sprinkles will just fall right off.

How to Shape Valentines Rice Krispie Treats

You can use cookie cutters to make any kind of shapes you want.

Once you’ve spread your Rice Krispies treats mixture in your pan or baking sheet, you can go ahead and start cutting out heart shapes with a heart-shaped cookie cutter. I recommend dipping it in water before cutting, so the treats will fall right off the cutter.

Be careful because the treats will still be quite hot, so just take your time.

Decorating and Flavor Alternatives for These Treats

There are many things you can do to decorate Rice Krispie hearts for Valentine's Day. First let's talk about decorating.

How to Decorate Rice Krispie Treats

Skip adding M&M's to the mixture, and add on top instead. You'd probably need to pipe on a little marshmallow fluff or melted candy melts and then sprinkle them on.
Use a piping bag to pipe a thin zig zag of melted red, white, or pink candy melts or melted chocolate all over the top of your Rice Krispie treats, and add Valentine sprinkles.
Instead of Valentine sprinkles, use pink Nerds. Kids LOVE Nerds.
Add festive sprinkles right into the Rice Krispie squares recipe instead of sprinkling them on top.
Make pops out of your Rice crispy treats by adding a lollipop stick into each of the treats.
Dip a portion of or the whole treat into melted candy melts or melted chocolate, and sprinkle with sprinkles.
Try different Valentine shape cookie cutters! Maybe X's and O's for hugs and kisses.
Decorate your heart-shaped Rice Krispie treats with adorable little Cupid's arrows made out of toothpicks and gummy hearts.

Alternative Flavor and Color Options

Make pink Rice Krispie treats by adding pink food coloring to the melted marshmallow mixture.
Add enough strawberry Jello mix to your marshmallow mixture to give the treats both a strawberry flavor and a pink color, sorta like strawberry Rice Krispie treats.
In addition to M&M's, add a handful of white chocolate chips into the crispy treat mixture.

As you can see, the options are endless with this sweet treat.

Expert Tips and Recipe FAQ's

Can I make Valentine's Day Rice Krispies treats in advance?

Yes, you can totally make these ahead of time. Make them the day before, and you're all set for the party the next day. I wouldn't make them more than 1-2 days in advance, though, as they can grow stale over a couple of days.

Why are my treats not chewy?

There may be a couple of reasons your treats aren't chewy. First, your marshmallows and cereal may not have been fresh; be sure to use fresh marshmallows and non-stale cereal. It's also important to cook the marshmallow mixuture on low to medium heat, so the marshmallows slowly and evenly melt. Also, did you press hard when you pressed the finished mixture into the pan? It's important to lightly press them into the pan and don't overly compress them down. Lightly pressing them will help with keeping the treats soft and chewy, rather than hard and tough as nails.

Why are my Rice Krispie treats not crispy?

You shouldn't have this problem if you follow this recipe to a t. But it could be that the recipe calls for too much butter. Too much butter will give an overly soft treat that doesn't compact together into a nice, uniform, crispy treat.

How should I store Rice Krispie treats with M&M's?

It's important to store your treats in anairtight containerorsealed plastic bag. You'll probably want to eat them within the first 2 or 3 days.
