Ingredients Equipment Method Notes

Ingredients
  

  • 1/4 cup whole milk, cold
  • 2 tablespoons heavy cream, cold
  • 1/8 teaspoon pure mint extract
  • 1/4 teaspoon pure vanilla extract
  • Whipped cream, for garnish
  • 1 tablespoon mini chocolate chips, for garnish
  • 1 maraschino cherry, for garnish

Equipment

  • Blender
  • Tall milkshake glass
  • Freezer
  • Measuring cups
  • Measuring spoons
  • Wide straw
  • Long-handled spoon

Method
 

  1. Place your serving glass and the blender pitcher in the freezer to chill for at least 15 minutes. This is the key to a thick, frosty milkshake.
  2. Pour the cold whole milk, heavy cream, pure mint extract, and pure vanilla extract into the bottom of the chilled blender pitcher. Starting with liquids helps the blender work efficiently.
  3. Add the scoops of hard-frozen mint chocolate chip ice cream on top of the liquids.
  4. Secure the lid and start the blender on a low speed, pulsing a few times to break up the ice cream. Increase the speed to medium-high and blend for only 30-45 seconds, just until the mixture is smooth but still very thick. Avoid over-blending, as it will thin the shake.
  5. Immediately pour the milkshake into the frosted glass. Garnish with a generous swirl of whipped cream, a sprinkle of mini chocolate chips, and a maraschino cherry on top.
  6. Serve at once with a wide straw and a long-handled spoon to enjoy every last drop.

Notes

For optimal results, use full-fat dairy and hard-frozen ice cream. To adjust thickness, add more ice cream for a thicker shake or a splash more milk for a thinner one. For a fun variation, blend in a mint chocolate cookie for a 'Cookie Crumble' shake, or add 1 ounce of crème de menthe or Bailey's Irish Cream for an adult version.
