No need to miss out on Valentine's Day conversation hearts anymore. Make your own with this recipe for Vegan Conversation Hearts Candy! Sure to put a smile on any vegan kiddo's face!

Every year around Valentine's day, the kids have some activity at school involving the dreaded conversation hearts. So, every year I hunt for a vegan version only to be let down by the lack of one. Those ever popular hearts seem innocent enough until you start reading the ingredient label and see that pesky little ingredient that seems to sneak its way into otherwise benign candies all too often. Gelatin! It's made from the skin, bones, and connective tissues of animals so it is most definitely not vegan and just plain gross. So, after having my hopes dashed again this year, I decided to get to work on creating these Vegan Conversation Hearts.
Ingredients
I first had to find out just what the non vegan hearts were made from so I would have a starting point for my own. For that, I turned to my favorite foodie scientist, Alton Brown. His recipe employs the aforementioned icky ingredient, but I have used agar before as a vegan counterpart to gelatin with success.
What is Agar?
Agar sometimes called agar-agar is a gelatinous substance obtained from algae and is completely vegan. It is used in a variety of desserts throughout Asia as well as being used in labs as a growth medium for culturing bacterias and fungus to be observed under microscope (because it's better than gelatin). It is available in powder and flake forms in Asian grocery stores and some health food stores as well as online. For this recipe, we'll be using the powder version.
Tip
When I made the first and second batch of these hearts I mistakenly grabbed guar gum from the cabinet rather than agar. Since the two have similar thickening properties, it worked just fine and as such you can use either one depending on what you have available. After realizing my mistake, I did make a third batch with agar to be certain it worked as well.
The only differences I noticed between the two, was that the guar gum had the tendency to meld back together after cutting out the hearts so you will need to cut and remove the shapes a few at time in order to avoid this. The texture of the guar gum hearts also remained a bit softer in the middle than with agar, but it is not at all unpleasant.
Instructions
In order to activate the setting properties of agar, it is necessary to dissolve the powder in liquid and then heat the mixture. This simple step is how the candy hearts will set and harden.


Once the agar or guar gum has been heated and gelled a bit, the next step is to mix in confectioner's sugar in a cup at a time until a dough has formed. You're looking for it to resemble play dough, not too sticky and holds it shape like you see above.
Colors & Flavors
As for coloring and flavoring the candy hearts I went the natural route using matcha green tea powder for green, beet powder for pink, ground turmeric for yellow and vanilla extract for white. Feel free to use food coloring, other powders, spices, and extracts to color and flavor however you like.
Now for the tedious part, cutting out all those tiny hearts. This is a great time to get any play dough fans involved to help roll and cut the hearts.
Drying time
The final step is letting the candies dry out. You want to arrange them on a parchment lined baking sheet and leave them on the counter to set and dry. This can take anywhere from a day to two to perhaps a little longer depending on how thick the candies are and the humidity where you live.

I like the texture after a couple of days. They're not quite as hard and definitely not chalky like store bought. They have a nice melt in your mouth feel that I prefer, kind of like the soft mints that crunch and then melt. My husband said they more closely resemble the store bought after the third day.
For the messages, I mix a pinch of beet powder with water until it forms a paste and use a toothpick to write on the hearts after they have dried. This step is completely optional as the hearts are cute enough without.
If you want to make these throughout the year skip the heart cutter altogether and use a circle cutter or for an even faster method just roll out the dough and use a pizza cutter to make small squares.

Recipe

Vegan Conversation Hearts Candy
Ingredients
- 2 tsp agar powder or ½ teaspoon guar gum
- ½ cup water
- 1 tbsp maple syrup
- ¼ teaspoon salt
- 5 cups confectioner's sugar + more for kneeding and rolling
Flavorings and color:
- ¼ teaspoon matcha or spinach powder green
- ¼ teaspoon beet powder pink
- ¼ teaspoon turmeric yellow
- ¼ tsp vanilla white
Instructions
- In a saucepan combine water and agar powder or guar gum. Don't worry if guar gum forms lumps as heating will dissolve them.
- Heat over medium heat until the mixture begins to bubble. Reduce heat and simmer for 5 minutes stirring often. The mixture will begin to form a gel.
- Pour gel into the bowl of stand mixer with the paddle attachment or use a hand mixer.
- Add confectioner's sugar one cup at a time beating on low until all sugar has been added and a dough that resembles play dough has formed.
- Divide dough into four equal pieces. Wrap 3 of the dough balls in plastic wrap and set aside. Take the fourth and make a small dent in the center of dough ball and add desired coloring or flavoring. Kneed on a surface sprinkled liberally with confectioner's sugar to incorporate into the dough thoroughly.
- Roll dough out on a surface sprinkled with confectioner's sugar to a thickness of ⅛ to ¼ inch. Cut out desired shape and transfer to a baking sheet lined with parchment paper. Set in an undisturbed area to dry.
- Continue this process working with one piece of dough at a time until all have been flavored, rolled, and cut.
- Allow candy hearts to dry undisturbed in open air for 1-3 days or until hardened. The length of time will depend on the thickness of the candies and the humidity in your area.
- After candy has hardened write messages if desired using a vegan food coloring pen or mix ¼ teaspoon beet powder with enough water to form a paste and use a toothpick.
- Store candies in a container in the pantry.

Hello! Were you able to find an appropriate sized heart shape cutter for these or did you cut out the shapes by hand?
Melissa says
Hi! I actually made one from an empty soda can. Clean the can of course and then cut the top and bottom off with sharp scissors. Then cut down the seam so the can opens up into a rectangle. Cut a 1 inch strip from the rectangle lengthwise and then shape it into a heart. There are video tutorials available if you need a visual. Search "how to make cookie cutters from soda cans". Hope this helps 🙂
