Preheat oven to 350 degrees.
Line a baking sheet with parchment paper.
Arrange 3 pretzels in a shamrock shape and place a Rolo candy in the middle.
Repeat with remaining pretzels and candy.
Bake for 3 minutes, until Rolo is slightly melted.
Insert a lollipop stick into the soft chocolate and then press a green candy in the middle of the chocolate Rolo.
Let harden then serve to your hungry kiddos!
