Here's what I did. I used half of this recipe and instead of vanilla I added 1/4 tsp strawberry flavoring from Hobby Lobby. Then at the end one drop of red food coloring to make them a light pink.
After flipping the marshmallow out of the pan onto powdered sugar, I used a medium sized heart shaped cookie cutter to cut them out. Then dipped the sticky edges into more powdered sugar til they were completely coated.
Then I melted white chocolate bark and dipped the tops into that and then sprinkled them. To make them pops, I lightly greased the ends of popsicle sticks and twisted them up into the marshmallow. These would be good with regular chocolate too!
