This Ninja Slushi Shamrock Shake recipe is a refreshing and minty homemade milkshake that captures the festive spirit of St. Patrick's Day.

It's a fun and easy way to enjoy a classic Shamrock Shake with a smooth, creamy texture and a perfect balance of mint flavor.

Ingredients

Milkshake Ingredients

  • 4 cups milk
  • 1 cup sweetener or sugar
  • 7-8 drops green food coloring
  • 1/2 teaspoon pure mint extract (Not peppermint extract; adjust to 3/4-1 teaspoon for stronger mint flavor)

Instructions

  1. Mix Ingredients: In a large cup or pitcher, whisk together the milk, granulated sugar (or your chosen sweetener), pure mint extract, and green food coloring until fully combined. Taste the mixture and adjust the mint extract accordingly; add more milk if the mint flavor is too strong.
  2. Pour into Ninja Slushi: Transfer the prepared mixture into your Ninja Slushi machine’s container. Select the 'milkshake' setting on your Ninja Slushi to begin the churning process.
  3. Process the Shake: Allow the Ninja Slushi to churn the mixture for 15 to 45 minutes depending on the sugar content and liquid temperature; in this case, about 20 minutes was needed for optimal texture.
  4. Serve the Shake: Once the cycle is complete, place a cup under the self-serve spout and pull the handle to dispense your freshly made Shamrock Shake. Enjoy immediately for best taste and consistency.

Notes

  • Use pure mint extract, not peppermint extract, for the authentic Shamrock Shake flavor.
  • Adjust the amount of mint extract based on your personal taste preference to avoid overpowering the shake.
  • Sweetener choice can be sugar or a sugar substitute; adjust churning time based on sugar content.
  • The Ninja Slushi machine requires time to properly freeze and churn the shake mixture—do not rush this process for best results.
  • The green food coloring is optional but provides the classic Shamrock Shake appearance.
