How to Make Blueberry Chocolate Lava Latte and Milk Tea with Fresh Grass Jelly

Whisk together 2 oz sweetened condensed milk, 1 oz fresh milk, 2 scoops unsweetened dark chocolate powder, and 1 oz blueberry puree to make enough chocolate lava syrup for two drinks. For the milk tea base, brew 2 tea bags in about 180 ml of hot water to yield roughly 150 ml of tea, then stir in one scoop of non-dairy creamer. Split the syrup between two glasses, top one with fresh milk and the other with the milk tea, then add fresh grass jelly to both.

A two-drink recipe built on a homemade blueberry-flavored chocolate lava syrup made from sweetened condensed milk, fresh milk, unsweetened dark chocolate powder, and blueberry puree. One serving uses fresh milk as the base and the other uses strongly brewed black milk tea, both finished with fresh grass jelly.

What you need

  • mixing cup or small bowl
  • whisk
  • measuring tools
  • two serving glasses
  • kettle or hot water source

Method

  1. Brew 2 tea bags in about 180 ml of hot water to make a strong concentrate, yielding roughly 150 ml of brewed tea

    A concentrated brew is essential so the black tea character comes through after the chocolate lava and creamer are added

  2. Stir one scoop of non-dairy creamer into the hot brewed tea until fully dissolved, then set aside

    This becomes the milk tea base for one of the two drinks

  3. In a mixing cup, combine 2 oz sweetened condensed milk with 1 oz fresh milk (or evaporated milk for a richer texture)

  4. Add 2 scoops of unsweetened dark chocolate powder to the milk mixture and whisk vigorously until completely smooth with no dry lumps

    Using a whisk speeds up incorporation; the fat and sugar in the condensed milk help the chocolate powder disperse evenly

    Expert tipThe finished base should be thick, glossy, and uniform in color before you add any fruit

  5. Add 1 oz of blueberry puree to the chocolate lava base and whisk again until fully combined

    Per single cup the amount is about 15 ml; other fruit purees such as strawberry can be substituted in the same quantity

    Expert tipThe blueberry is intended as a subtle hint rather than a dominant flavor — a well-flavored puree delivers more impact than a larger volume of a weak one

  6. Split the finished blueberry chocolate lava mixture evenly between two serving glasses

  7. Top one glass with fresh full-cream milk for the latte, and top the other with the cooled blueberry milk tea for the milk tea variant

    The latte will appear lighter and more milky; the milk tea version shows a deeper color from the black tea

  8. Add fresh grass jelly to both drinks and give each a gentle stir before serving

Why this works

Sweetened condensed milk provides body, sweetness, and binding power, allowing the unsweetened dark chocolate powder to emulsify into a dense, glossy lava texture rather than sinking or clumping. Diluting the condensed milk with a small amount of fresh milk prevents over-sweetness and fine-tunes the syrup's consistency. Incorporating blueberry puree directly into the syrup base ensures the fruit flavor is distributed evenly through every sip rather than pooling as a separate layer. Brewing two tea bags in a reduced volume of water creates a concentrate strong enough to assert itself once the chocolate lava and non-dairy creamer are added.

Where beginners go wrong

  1. 1

    Chocolate powder clumps instead of dissolving smoothly

    Always combine the condensed milk and fresh milk first, then add the chocolate powder and whisk immediately — the fat and sugar in the condensed milk create an emulsifying environment that helps the dry powder incorporate

  2. 2

    Blueberry flavor is too faint in the finished drink

    The creator intends the fruit as a subtle hint; if you want a more pronounced presence, choose a more intensely flavored puree rather than adding a larger volume, which would dilute the chocolate base

  3. 3

    Milk tea base tastes weak against the chocolate lava

    Use two tea bags in only about 180 ml of water to produce a concentrated yield of roughly 150 ml; do not add extra water and do not cut the steep time short

  4. 4

    Drink is too sweet overall

    Nearly all the sweetness comes from the sweetened condensed milk; reduce its quantity slightly or substitute a portion with evaporated milk to lower sweetness while retaining the body and richness of the lava base

What you should taste

A deep, rich chocolate flavor carries a gentle blueberry brightness that lifts each sip without overwhelming the cocoa. The latte version is creamy and smooth with a milky softness, while the milk tea version adds a pronounced black-tea character that makes the drink feel bolder and more complex. Both are described by the creator as very delicious and refreshing.

FAQ

Can I use a fruit other than blueberry?

Yes — the creator explicitly states that many flavors pair well with chocolate and names strawberry as another popular choice; any fruit puree that complements chocolate can be used in the same quantity

Which version — the fresh milk latte or the milk tea — is more affordable to make?

According to the creator, the milk tea version costs less because brewed black tea is cheaper than fresh milk

Can evaporated milk replace fresh milk in the chocolate lava syrup?

The creator confirms it can, and notes that evaporated milk produces a richer result than fresh milk
