Charcoal Milk Tea (with Roasted Oolong + Sweet Cream)

Millie Pham

Smoky, creamy, and totally different—in the best way.

Hey, you’ve gotta try this.

If you love milk tea but want something a little bold, this Charcoal Milk Tea is it.

The roasted oolong gives it this deep, toasty flavor, and the activated charcoal adds a cool twist—kind of smoky, a little earthy, and super smooth.

Pour that sweet cream over the top, and it turns into this layered beauty that tastes just as amazing as it looks.

It’s chill, fancy-feeling, but secretly easy to make. Let’s do it!

  • 1 cup water
  • 1/4 tsp activated charcoal powder (food-grade)

Why I Love This Recipe

Charcoal Milk Tea

This is one of those drinks that feels like a treat. The first time I had a charcoal milk tea was at a tiny tea shop in L.A., and I was blown away. The look is so dramatic, but the flavor? Even better. It’s now my go-to when I want something cozy and cool.

What I love about it:

  • That roasted oolong gives you deep, toasty flavor—like a campfire in a cup.
  • The activated charcoal makes it look amazing and gives it that earthy vibe.
  • Sweet cream pulls it all together so it’s bold but super smooth.
  • It’s refreshing iced, but honestly, it’s great warm too.

Why This Recipe Works (Quick Science)

  • Roasted oolong is partially oxidized, which gives it a rich, toasty profile without bitterness—perfect with creamy ingredients.
  • Activated charcoal doesn’t add much flavor but changes the color and adds subtle earthy notes. It’s porous and absorbs flavor in a unique way, letting the oolong and cream shine through.
  • Sweetened condensed milk blends better than sugar and gives that thick, creamy mouthfeel without needing extra steps.

Meal Plan Ideas

  • Pair it with a bento-style lunch for something savory + sweet.
  • Sip alongside an afternoon snack like mochi or a cookie.
  • Serve as a fancy drink at your next brunch—super Instagrammable.

Common Mistakes

  • Using too much charcoal. A little goes a long way—more than 1/4 tsp and it gets chalky.
  • Skipping the straining step. You don’t want leaves or powder bits floating around.
  • Not using roasted oolong. Regular oolong works, but it won’t have that deep, smoky taste.
  • Adding cream too fast. Pour slowly to get those pretty swirls.

What to Serve With It

  • Butter mochi
  • Egg salad sandwich
  • Japanese cheesecake
  • Crispy tempura
  • Black sesame cookies

Tools You’ll Need

  • Small saucepan
  • Fine mesh strainer
  • Tall glass
  • Spoon
  • Measuring spoons and cup
  • Small bowl for mixing cream
  • Glass pitcher (optional, for serving)

Substitutions & Variations

  • No oolong? Use strong black tea or genmaicha.
  • Vegan version? Use oat milk and coconut condensed milk.
  • Less sweet? Use just milk and a drizzle of honey instead of condensed milk.
  • Hot version? Skip the ice and serve warm with frothed milk.

Make-Ahead Tips

  • Brew the oolong ahead and keep in the fridge (up to 2 days).
  • Mix the sweet cream ahead and store it covered.
