A thick, nutty Japanese-inspired milkshake that blends toasted soybean flour with vanilla ice cream, cold milk, and a deep, molasses-rich brown sugar syrup. Think roasted peanut butter meets caramel, with a silky finish.

Steps

Before you start

Make the brown sugar syrup first: it needs about 20 minutes to cool completely, and hot syrup will melt the ice cream.
Chill two tall glasses in the freezer for 15 minutes for a colder, slower-melting shake.
Take the ice cream out of the freezer 5 minutes before blending so it scoops easily, but keep it firm, not soupy.
Use kinako (roasted soybean flour) from a Japanese or Asian grocery. Check that it smells toasty and nutty, not stale.

1
Simmer the syrup
- In a small saucepan, combine the dark brown sugar, water, and salt.
- Set over medium heat and stir until the sugar dissolves, about 1 minute.
- Let it bubble gently, without stirring, for 2 to 3 minutes.

Ready when: Syrup is glossy, lightly thickened, and coats the back of a spoon; it will thicken more as it cools.
Tip: Don't boil it longer than 3 minutes or it can turn to hard caramel once cooled.
2
Cool the syrup
- Pour the syrup into a small bowl or jar and let it cool to room temperature, about 20 minutes.
- Meanwhile, put the glasses in the freezer.

Ready when: The syrup feels neutral or cool to the touch, not warm.
Tip: To speed it up, set the bowl in a larger bowl of ice water for 5 minutes.
3
Load the blender
- Pour the cold milk into the blender first.
- Add 3 tablespoons (about 21 g) of the cooled syrup, then 4 tablespoons (28 g) of kinako, and the vanilla extract if using.
- Add the ice cream scoops on top.

Tip: Liquid goes in first so the blades catch the ice cream and don't air-pocket.
4
Blend until smooth
- Secure the lid and blend on low for 10 seconds, then medium-high for 15 to 20 seconds.
- Stop when no streaks of kinako or ice cream remain.
- If the blender stalls, pause and stir with a spatula, then resume.

Ready when: The shake is thick, uniformly pale tan, and slowly falls off a spoon in a ribbon.
Tip: Over-blending warms and thins the shake. Stop as soon as it's smooth.
5
Drizzle the glasses
- Remove the chilled glasses.
- Spoon about 1 tablespoon (7 g) of the remaining syrup into each glass and tilt and turn so it streaks down the sides.

Ready when: Dark syrup ribbons are visible on the inside of each glass.
6
Pour and dust
- Divide the shake between the glasses.
- Put the reserved 1 teaspoon of kinako in a fine sieve and tap it over the tops.
- Serve immediately with wide straws or long spoons.

Ready when: Tops are lightly dusted with golden kinako.
Tip: Serve right away; the kinako thickens the shake as it sits, so stir if it stiffens.

Tips

Sieve the kinako if it looks clumpy so it blends in without gritty specks.
For a thicker shake, reduce milk to ½ cup (120 ml); for thinner, increase to 1 cup (240 ml).
Add a pinch of salt to the blender if you like a stronger salted-caramel contrast.
Top with a few mochi pieces or whipped cream for a dessert-style version.

Make ahead

The brown sugar syrup can be made up to 2 weeks ahead and stored in a sealed jar in the fridge. Let it come to room temperature or warm it for 10 seconds in the microwave and cool slightly before using.

Storage & reheating

Best served immediately. Leftover shake can be frozen in a covered container for up to 1 week; thaw 10 minutes and re-blend with a splash of milk. Leftover syrup keeps in the fridge for 2 weeks. Kinako keeps in a sealed bag in the fridge for 3 months.

Substitutions

dark brown sugar → kuro mitsu (Japanese black sugar syrup) or muscovado sugar. Use 3 tablespoons (45 ml) kuro mitsu in place of the homemade syrup for a smokier, more authentic flavor.
whole milk → unsweetened oat milk. Gives a creamy dairy-free base; pair with dairy-free vanilla ice cream.
kinako (roasted soybean flour) → finely ground roasted peanuts or peanut butter powder. Flavor is similar but less earthy; use the same weight.
vanilla ice cream → black sesame ice cream. Makes a deeper, toastier shake; skip the vanilla extract.
