Add the the ice cream, milk, food coloring, and extract to a blender and blend on high speed until smooth.

Notes
Choose High-Quality Ice Cream: Select a creamy, premium ice cream for an indulgent Shamrock Shake experience.
Healthier Milk Options: For a lighter version, substitute whole milk with low-fat or almond milk, which makes the shake less creamy but still delicious.
Mint vs. Peppermint Extract: Use mint extract, not peppermint, for that authentic Shamrock Shake flavor. Peppermint extract will give it a candy cane-like taste.
Moderation with Mint Extract: Start with a 1/2 teaspoon of mint extract; it's potent. For more minty flavor, add gradually. Just a few drops can make a big difference.
Shamrock McFlurry Twist: Add crushed Oreo cookies to the blender to mimic the popular Shamrock McFlurry.
