We make these little treats for just about every holiday; it's so easy to make them holiday specific by changing the colors of the m&m candies.
I used Snyder's Butter Snaps square pretzels, Rolo candies, and Valentine m&m candies.
Preheat the oven to 350 degrees. Place the square pretzels on a baking sheet, place one Rolo on each pretzel, and put them in the oven for approximately two minutes (when the Rolo candies are soft and squishy). Remove from the oven and immediately place one m&m candy on each Rolo.
The Story of Valentine's Day by Nancy J. Skarmeas explains why we celebrate Valentine's Day. We own this book and read it every year. It's perfect for children of all ages.
