This easy and refreshing key lime pie milkshake is the perfect summer treat! Creamy vanilla bean ice cream blended with AE Dairy whole milk, fresh key lime juice, lime zest, and honey. These decadent shakes are so good topped with crushed graham crackers or waffle cones to give them that key lime pie taste. A heaping dollop of whipped cream and a lime slice finishes off this tasty dessert.

Highlights of this key lime pie milkshake and why you’ll love it:

  • Easy Recipe: this recipe is so quick and easy, it can also be customized as desired making this perfect for whatever you have on hand.
  • Kid friendly: kids and adults will love this equally! The vanilla bean ice cream is rich and decadent, pairing perfectly with the tangy key lime juice. This is an elevated vanilla shake and the crunchy toppings are so fun.
  • Simple ingredients: vanilla bean ice cream, whole milk, honey, key lime juice and zest. That’s all you need! Plus your favorite toppings like homemade or store-bought whipped cream, a lime wedge, crushed graham crackers, or ice cream cones!
  • Refreshing: the bright and tangy flavors from the lime make this extra refreshing, lightening up the ice cream very nicely! This is great for warm summer nights or days by the pool!
  • Restaurant copycat: this at home recipe is very similar to the Chick-fil-A frosted key lime.

AE Dairy whole milk adds the perfect amount of creamy richness to the shake. If you like the notes of citrus in the recipe, you’ll love this Easy 2 Ingredient Frosted Lemonade – it’s very similar!

Ingredients & Ingredient Notes:

  • Vanilla bean ice cream: any store-bought or homemade ice cream will work for this recipe. Other flavors like lemon, lime, or French vanilla will work. Dairy-free ice cream can be substituted,
  • AE Dairy whole milk: any type of milk will work, but I like the thick, richness whole milk gives. You can use skim milk, 2% milk, or half and half. A non-dairy milk may be substituted.
  • Key lime juice: fresh lime juice is the way to go here, but if you’re in a pinch you can use bottle lime juice. Key limes are a bit more tart and sweet than the traditional grocery store lime. If you can’t find key limes, use traditional lime juice.
  • Lime zest: if you’re using homemade lime juice, you might as well zest the lime first and get fresh lime zest. This adds extras flavor and gives the shake some fun specs throughout.
  • Honey: honey adds the perfect touch. It’s not necessary but I enjoy the subtle floral hints and the extra richness it provides.
  • Toppings: a dollop of fresh or packaged whipped cream, a lime wedge, and some crushed ice cream cones is the perfect topping. Crushed graham crackers or Nilla wafers are also fun, these represent the “crust” part of the key lime pie.

Whipped cream and crunchy wafers or graham crackers give this the crust-like texture and flavor similar to key lime pie. I like to serve these in tall glasses or milkshake glasses for a nostalgic feeling, a fun straw and you’re set for ice cream at home! This is a fun treat for all, perfect for the whole family.

Tools I used for this easy recipe:

  • Rubber Spatula – a must have! Easily combine the ice cream mixture with a rubber spatula. I like these because they don’t come apart so I don’t have to worry about water getting inside the spatula and causing mold.
  • Blender – This is the best affordable blender, perfect for blending this drink. It is powerful and has a bunch of different settings. The base of the blender is large enough so you don’t have to do multiple batches.
