There’s something about a banana milkshake that feels like pure nostalgia in a glass — thick, creamy, and just sweet enough to taste like dessert without being over the top. And when you make it in the Ninja Slushi, you get that perfect frozen texture every single time, no guesswork required.

This version uses a box of banana cream instant pudding for big, bold banana flavor and an extra-silky texture — no fresh bananas or blending required. It comes together in one bowl, freezes to that ideal spoon-and-sip consistency, and works just as well for a lazy weekend treat as it does for cooling down on a hot afternoon.

Let’s get into it.

Why You’ll Love This Recipe

  • Just four simple ingredients you probably already have on hand
  • No blender chunks or icy shards — the Slushi does the work for a smooth, even freeze
  • Instant pudding does double duty, adding rich banana flavor and a creamy, thick body
  • Endlessly customizable — add peanut butter, chocolate, or a shot of espresso and make it your own.

If you’re new to the machine, it’s worth browsing through a few other Ninja Slushi recipes first to get a feel for how versatile it really is.

Ingredients

Ninja Slushi banana milkshake ingredients: milk, heavy cream, banana cream pudding, and sugar
  • Milk – Forms the creamy base and helps everything blend smoothly.
  • Heavy cream – Adds richness and a smooth, velvety milkshake texture.
  • Banana cream instant pudding – Delivers bold banana flavor and creamy thickness.
  • Sugar – Sweetens the shake and balances the banana flavor.

Tip: The pudding mix already brings sweetness and flavor, so taste your base before pouring it in and adjust the sugar down if you prefer a less-sweet shake.

Instructions

Pouring banana milkshake mixture into the Ninja Slushi vessel

Step 1. In a large bowl, whisk together the milk, heavy cream, banana cream instant pudding, and sugar until everything is fully combined and the pudding mix is completely dissolved with no lumps.

Step 2. Pour the mixture into the vessel.

Step 3. Select MILKSHAKE. The preset will start at the default/optimal temperature for ideal texture. If desired, adjust the temperature to your preference.

Step 4. Once the frozen drink reaches optimal temperature, the unit will beep three times. Serve immediately, topped with whipped cream and a few banana slices as desired.

Tips for the Perfect Banana Milkshake

  • Whisk until smooth. Make sure the pudding mix is fully dissolved before pouring — any undissolved clumps can leave a grainy texture.
  • Go full-fat. Whole milk and heavy cream give you that rich, diner-style thickness. Lower-fat swaps will still work but the texture will be lighter and icier.
  • Chill your ingredients first. Starting with cold milk and cream helps the mixture reach the ideal frozen texture faster.
  • Serve right away. Milkshakes are at their dreamy best straight out of the machine, so have your glasses and toppings ready to go.

Fun Variations

  • Peanut Butter Banana: Whisk in 2 tablespoons of creamy peanut butter for a shake that tastes like a frozen PB&B sandwich. If you love that combo, my Ninja Slushi Protein Milkshake is a great next one to try — banana and peanut butter both work beautifully in it.
  • Chocolate Banana: Add ¼ cup chocolate syrup for a classic combo the whole family will love. It’s basically a mashup of this recipe and my Chocolate Ninja Slushi Milkshake.
  • Banana Coffee: Stir in a shot of cooled espresso for a caffeinated afternoon pick-me-up.
  • Banana Bread Shake: Add a pinch of cinnamon and a dash of nutmeg for cozy banana-bread vibes.

Storage

Banana milkshakes are best enjoyed fresh, but if you have leftovers, pour them into an airtight container and freeze. Let it sit at room temperature for a few minutes to soften before scooping, or re-run it through the Slushi to bring back that smooth texture.

Faqs

Can I make this Ninja Slushi banana milkshake without pudding? Yes. Swap the banana cream instant pudding for 2 mashed ripe bananas and 1 teaspoon vanilla extract. The texture will be a touch lighter, but you’ll still get great banana flavor.

Why is my milkshake too icy or not thick enough? This usually comes down to fat content. Whole milk and heavy cream give the richest, thickest result. If your shake freezes too hard, let it sit for a minute or two before serving.

Can I use low-fat or plant-based milk? You can. Almond, oat, or 2% milk all work, but the shake will be lighter and slightly less creamy than the full-fat version.

How much sugar should I use? The recipe calls for 2 cups, but since the pudding mix is already sweetened, you can taste your base and scale the sugar down to your preference.

Do I have to add the mixture to the machine right away? No. You can whisk the base ahead of time and keep it chilled in the fridge for up to 24 hours before pouring it into the Slushi.

Can I store leftovers? Milkshakes are best fresh, but you can freeze leftovers in an airtight container. Let it soften a few minutes or re-run it through the Slushi to bring back that smooth texture.

What toppings go well with a banana milkshake? Whipped cream and fresh banana slices are classic. Crushed vanilla wafers, a caramel drizzle, or a sprinkle of cinnamon are all great additions too.
