How to Make Banana Milk Iced Coffee

Mix banana milk and ice cream together in a 1:1 ratio until the ice cream melts into a thick, heavy cream. Transfer to a tumbler and shake, then layer over ice and pour cold coffee concentrate over the top. Stir before drinking.

A thick, dessert-style iced coffee built on a 1:1 blend of banana milk and ice cream stirred into a rich cream base, then layered with cold-brewed coffee concentrate. Heavy, smooth, and fragrant with banana, it drinks like a caffeinated banana cream shake.

Ratio

1:1 banana milk to ice cream

Difficulty · BeginnerYield · 1 drink

What you need

  • a mixing bowl
  • a spoon or spatula
  • a tumbler with a sealable lid
  • a tall serving glass

Method

  1. Measure out banana milk and ice cream in equal parts and add both to a mixing bowl

    The creator uses a 1:1 ratio; no specific gram weight is given, so size the batch to your glass

  2. Stir the mixture until the ice cream is fully melted and the combined base is thick and heavy

    The goal is a dense, spoonable cream — not a thin liquid; keep stirring until the texture is uniform and coats the spoon

    Expert tipStop when the mixture is smooth and cohesive; a lumpy or watery result means under- or over-mixing

  3. Pour the banana cream base into a tumbler, seal the lid, and shake vigorously until fully integrated

    Shaking aerates the base slightly and ensures even consistency throughout

  4. Brew a coffee concentrate using cold water; use as little water as possible to produce a bold, strong extract

    The creator notes this coffee type works well even in cold water — brew it cold and keep it concentrated so it can cut through the sweet banana base

    Expert tipErr on the side of stronger rather than weaker; the dense banana cream will mute subtle coffee

  5. Fill a tall serving glass with ice

  6. Pour the shaken banana cream mixture over the ice first

    Adding the cream base before the coffee lets it settle as the lower, denser layer

  7. Pour the cold coffee concentrate over the banana cream layer

    The coffee floats slightly on top, creating a layered appearance

    Expert tipPour slowly along the inside edge of the glass to preserve the visual layers

  8. Stir gently to combine just before drinking

    The creator recommends mixing before each sip so both the banana cream and coffee flavors are present throughout

Why this works

Stirring ice cream into banana milk at a 1:1 ratio before shaking emulsifies the fat and sugar into a thick, stable base that carries both banana flavor and coffee concentrate evenly. Cold-water coffee concentrate preserves the chill of the drink and avoids heating a cream-based liquid that could break or curdle. Layering the coffee over the cream base last means the two elements stay visually distinct and marry only when stirred, giving the drinker control over the final balance.

Where beginners go wrong

  1. 1

    Base is too thin and watery

    Do not over-stir once the ice cream melts — stop when the mixture is thick and cohesive. If it has become too liquid, chill it briefly before shaking to re-thicken

  2. 2

    Coffee flavor disappears in the drink

    Use the minimum possible water when brewing the coffee to keep the concentrate bold; a weak extract is overwhelmed by the sweet, dense banana cream base

  3. 3

    Drink separates into undrinkable layers

    The cream base and coffee concentrate have different densities; stir gently just before drinking and between sips to keep them integrated

  4. 4

    Drink is too sweet

    Increase the proportion of coffee concentrate or slightly reduce the ice cream to banana milk ratio; the ice cream is the primary source of sweetness

What you should taste

The banana fragrance arrives first, followed by deep coffee bitterness. The melted ice cream gives the drink a lush, heavy body that feels closer to a dessert shake than a standard iced coffee. The ice cream balances the coffee and banana together on the finish — smooth, sweet, and satisfying.

FAQ

Does the coffee need to be hot-brewed?

No. The creator specifically uses cold water to make the concentrate, which keeps the entire drink chilled and avoids adding heat to the delicate banana cream base.

Can I use a different banana milk?

The creator uses Binggrae banana milk. Any sweetened banana-flavored milk can work as a substitute, though flavor intensity and sweetness level will vary.

Is the ice cream flavor specified?

The creator does not specify a flavor; the transcript refers only to ice cream generically, so the choice is left to personal preference.
