How to Make a Dunkin’ Mixed Berry Daydream Refresher
Start with a strong cup of chilled green tea. Mix it with blueberry and strawberry syrups plus a hint of dragonfruit powder for that signature color. Float in oatmilk like a soft cloud, then top it off with a whipped, glossy cold foam made from skim milk and cream. Sip slow. Let the berry vibes roll.

Ingredients (1 medium-size serving, 22 oz)
Prep Time: 10 minutes
Cook Time: 0 minutes
Total Time: 10 minutes
Servings: 1 large drink
Berry Refresher Base
- 1 cup strong brewed green tea (chilled)
- 1 tablespoon blueberry syrup (homemade or Monin-style)
- 1 tablespoon strawberry syrup
- ½ teaspoon dragonfruit powder (for color + tropical lift)
- 1 to 2 teaspoons simple syrup or liquid cane sugar (optional)
- 1 teaspoon fresh lemon juice (optional, for brightness)
Creamy Layer
- 6 oz barista-style oatmilk (cold, like Planet Oat Extra Creamy)
Cold Foam Topping
- 3 tablespoons very cold skim milk
- 1 tablespoon heavy cream
- 1 to 2 teaspoons vanilla syrup or liquid sugar
Tools You’ll Need
- Milk frother or handheld frothing wand
- Blender bottle or cocktail shaker
- Tall glass or tumbler (22 oz or more)
- Measuring spoons + cup
- Long spoon or straw
Instructions
1. Brew and chill your green tea
Steep 1 bag of green tea in ½ cup hot water for 5 minutes. Let cool completely. Double the strength if using a large glass, since it will be diluted over ice. Chill in the fridge.
2. Mix the berry base
In a shaker or blender bottle, combine chilled tea, blueberry syrup, strawberry syrup, dragonfruit powder, lemon juice, and optional simple syrup. Shake for 10–15 seconds until well blended and the powder dissolves.
3. Fill the glass
Add ice to a tall glass until almost full. Pour the berry mixture over the ice.
4. Add the oatmilk
Slowly pour the oatmilk over the back of a spoon to create soft layers. Watch as it swirls into the berry base.
5. Froth the cold foam
In a small cold jar or milk frother, whip together skim milk, cream, and vanilla syrup until thick and airy. You want pourable, silky foam, not stiff peaks.
6. Top it off
Spoon the cold foam gently over the top of the drink. Let it cascade naturally and drift into the drink like a dream. Sip with a wide straw or spoon to get both layers.
Tips for Success
- Use cold, barista-style oatmilk for the creamiest swirl that doesn’t separate.
- Chill all liquids before assembling or your foam will sink too fast.
- For best cold foam: start with super cold milk and use a handheld frother in a tall glass. No blender needed.
- Use freeze-dried dragonfruit powder to boost color naturally. Just a pinch will do.
- Sweeten to taste: if your syrups are sweet enough, skip the extra sugar.
What to Serve With
Fruity pairings
- Fresh watermelon sticks – The crisp, hydrating bite of chilled watermelon goes hand-in-hand with the juicy berry swirl.
- Blueberry muffins – Soft and lightly sweet, they echo the berry flavor and soak up the drink’s creaminess in each bite.
- Strawberry cream cheese toast – A slice of sourdough with whipped cream cheese and sliced berries is a perfect brunch companion.
Salty & snacky
- Salted popcorn or pretzel sticks – That little hit of salt makes the sweet, creamy refresher taste even more vibrant.
- Cheddar crackers – The sharp, savory crunch contrasts beautifully with the drink’s smoothness.
- Avocado toast with chili flakes – Creamy meets creamy, with a bit of heat to keep things interesting.
Treat yourself moments
- Lemon shortbread cookies – A buttery finish with a citrus pop helps lift every berry sip.
- Mini berry tarts – Think crisp pastry with blueberry or raspberry jam, echoing the flavors without overwhelming them.
- Yogurt bark with dried fruit – Break off a piece of frozen yogurt bark for a cooling bite between sips.
Variations
Lighter Iced Berry Refresher
Skip the cold foam and use unsweetened oatmilk to cut down on calories and sugar. Still refreshing, just a little more breezy.
Creamy Coconut Berry Refresher
Swap oatmilk for creamy coconut milk (the canned kind, diluted). The tropical twist makes this feel even more exotic.
Mixed Berry Mango Version
Add 2 tablespoons mango nectar to the tea base for an extra pop of sweetness and sunshine.
Caffeinated Boost
Add a shot of chilled espresso or 1 tsp matcha powder for an extra pick-me-up. The espresso version gives it a Starbucks-style twist, while matcha deepens the tea vibes.
Boozy Berry Spritz
Blend with a splash of berry vodka or white rum for a weekend patio drink. Best served over crushed ice with a mint sprig.
