  • Total Time: 5 minutes
  • Yield: 2 large milkshakes (approximately 16 oz each) 1x

Ingredients

Scale

For the Milkshake Base:

  • 2 medium ripe bananas (preferably frozen)
  • 4 large scoops vanilla ice cream (about 2 cups)
  • ¾ cup whole milk
  • 2 tablespoons chocolate syrup, plus more for drizzling
  • 2 tablespoons strawberry syrup or sauce

For Topping & Garnish:

  • Whipped cream (generous amount)
  • 2 maraschino cherries with stems
  • Additional chocolate syrup for drizzling
  • Additional strawberry syrup for drizzling
  • 2 tablespoons crushed peanuts (optional)
  • Rainbow sprinkles (optional)

Instructions

  • Prepare the banana: If using fresh bananas, peel and break into chunks. For the thickest, frostiest results, use bananas that have been peeled, sliced, and frozen for at least 2 hours.
  • Add base ingredients to blender: Place the banana chunks, vanilla ice cream, milk, chocolate syrup, and strawberry syrup into your blender jar.
  • Blend until smooth: Blend on high speed for 30-45 seconds until completely smooth and creamy. Stop and scrape down the sides if needed. The consistency should be thick but pourable—add a splash more milk if too thick, or another scoop of ice cream if too thin.
  • Prepare your glasses: While the milkshake blends, drizzle chocolate syrup in a spiral pattern inside each serving glass, followed by strawberry syrup. This creates a beautiful striped effect when you pour in the milkshake.
  • Pour and serve: Divide the milkshake evenly between prepared glasses. Use a spatula to get every last drop from the blender.
  • Add toppings: Top each milkshake generously with whipped cream, creating a tall swirl. Drizzle additional chocolate and strawberry syrups over the whipped cream. Sprinkle with crushed peanuts and/or rainbow sprinkles if using.
  • Finish with cherries: Place a maraschino cherry with stem on top of each milkshake. Insert a wide straw and a long spoon.
  • Serve immediately: Milkshakes are best enjoyed right away while still thick and frosty. Serve with extra napkins—things might get deliciously messy!

Notes

  • For an extra-thick shake, freeze your banana chunks overnight and use ice cream straight from the freezer.
  • Taste the milkshake before pouring and adjust sweetness by adding more syrup if desired.
  • For a peanut butter banana split variation, add 2 tablespoons of creamy peanut butter to the blender.
  • Make it boozy for adults by adding 1-2 oz of banana liqueur, Kahlúa, or rum.
  • For a dairy-free version, use coconut milk ice cream and your preferred plant-based milk.
