This is crucial. You can totally mess up this vegan ice cream popsicle recipe and make it taste like toothpaste if you choose the wrong kind of mint. Even though this is a mint chocolate chip recipe, do not buy mint extract. I made this mistake once before when making a recipe that was mint chocolate flavored and it ended up tasting like a mouth full of toothpaste! Therefore it is crucial that you use pure peppermint extract for these mint chocolate chip ice cream popsicles. You may be wondering if this will cause it to taste like a candy cane. I can assure you that it will not and you will end up with the perfect minty flavor!
