I love conversation hearts.  Well, technically I love the idea of them but not the taste.  One night, as I was packing lunches, I had a great idea to put one in my husband’s and daughter’s lunch so when they sat down for lunch they got a heart from me that said “Love You” or “XOXO.”  I thought I was so clever. The problem was that they were so small neither one saw the little heart I sent them.  I was telling Laurie the story and she came up with the idea of making Conversation Hearts Rice Krispie Treats.  They turned out so cute. They are a great Valentine’s Day treat and so easy to make.  What a fun dessert to take to a child’s classroom for a Valentine’s Day Party.   And your family will love them too!

How to make the Rice Krispie Treat mixture

The base for this fun Valentine’s day treat is our Best Ever Rice Krispie Treat Recipe which we have adjusted and perfected over the years until it is now absolutely the best Rice Krispie Treat recipe we have ever tasted.  You can find all the directions you’ll need to make these delicious treats right here

For each color batch of Conversation Hearts Rice Krispie Treats you make you will need 2 tablespoons of butter, 2 cups of marshmallows, and 2 cups of Rice Krispies Cereal.   Melt the butter in a large pan on medium heat.  Add the marshmallows and stir until melted.  I was able to make 6 hearts out of this batch but your number may vary depending on how big your heart cookie cutter is and how thick you make your Rice Krispie Treat hearts.

For the White Conversation Hearts Rice Krispie Treats, simply mix in the 2 cups of Rice Krispie Cereal to the marshmallow mixture without adding any food coloring.

How to Color the Rice Krispie Treat mixture

For the colored Rice Krispie Treat hearts, add food coloring to the melted marshmallow mixture before you add the Rice Krispie cereal. We like the Wilton Color Right Food Coloring. You can make pretty vivid colors without using too much food coloring. We used the following food coloring combinations to make these pretty iconic conversation hearts colors:

Pink: 1 drop of Pink Wilton Color Right Food Coloring
Purple:  1 drop each of Pink, Red, and Blue Wilton Color Right Food Coloring
Green: 1 drop of Yellow and 1/2 drop of Blue Wilton Color Right Food Coloring
Yellow:  1 drop of Yellow Wilton Color Right Food Coloring

How to assemble the Rice Krispie Conversation Hearts

We used a medium-sized heart cookie cutter.

We made one color of the Rice Krispie Treat mixture at a time because you don’t want the mixture to cool too much while you are making the Hearts. Once the mixture had cooled enough so we could handle it without burning our fingers we started filling the cookie cutters to form our hearts.  We like molding the mixture into the cookie cutters this way instead of making a sheet of Rice Krispie Treats and cutting out the hearts like a traditional cookie. You will have smoother and prettier edges this way.

We made a half batch of our Best Buttercream Frosting to pipe on the Conversation Heart “sayings”.  It is easy to make and so delicious.  You will find the recipe and detailed instructions on how to make it here.  We tinted it red with 4 drops of Red Wilton Color Right Food Coloring.

Finally, we piped on some fun sayings like Be Mine, XOXO, Marry Me, My Baby, and Awesome!
