Celebrate Cinco de Mayo in sweet style. These are a sweet and spicy spin on a nostalgic frozen treat, perfect for any Cinco de Mayo fiesta! The best part: you dont have to worry about running after the ice cream truck, especially if youve had a few margaritas. And the Mexican cinnamon ice cream is so easy to make, you dont even need an ice cream machine. Of course, if you want to skip a step, you can always use store-bought ice cream in whatever flavor you prefer.
