Summer is the season of iced lattes — and once you know the base formula, the variations are endless. From classic brown sugar oat milk to lavender honey to coconut matcha, here are the best summer iced latte variations you can make at home with simple ingredients.
The Base Formula
Every iced latte starts with the same foundation:
- Espresso or strong coffee concentrate — 2 shots (60ml) or 150ml cold brew concentrate
- Milk of choice — 150–200ml
- Ice — a full glass of large cubes
- Optional sweetener — to taste
Master this base and every variation below is just a matter of swapping the milk and adding a flavoring element.
Variation 1: Brown Sugar Oat Milk Latte
The most popular iced latte of the last five years. Rich, caramel-sweet, and deeply satisfying.
- 2 shots espresso or 150ml cold brew
- 1 tbsp brown sugar (dissolved in the warm espresso)
- 200ml barista oat milk over ice
- Optional: cinnamon sprinkle on top
Use the Blueprint Coffee Penrose Espresso Blend for a naturally caramel-forward base that amplifies the brown sugar notes.
Variation 2: Vanilla Honey Latte
Floral, sweet, and elegant. A sophisticated alternative to the classic vanilla latte.
- 2 shots espresso or 150ml cold brew
- 1 tsp raw honey (dissolved in warm espresso)
- ½ tsp vanilla extract
- 200ml whole milk or oat milk over ice
Variation 3: Coconut Cold Brew Latte
Tropical, smooth, and naturally sweet. Perfect for the hottest summer days.
- 150ml cold brew concentrate
- 150ml coconut milk (full fat for richness)
- Ice
- Optional: toasted coconut flakes on top
The Diving Moose Coffee Sumatra Gayo Organic Medium Dark Roast makes an exceptional cold brew base for this variation — its earthy, chocolatey notes pair beautifully with coconut.
Variation 4: Lavender Oat Milk Latte
Floral, calming, and visually stunning. Make a simple lavender syrup (1:1 sugar and water with dried lavender, steeped 10 minutes and strained) and add 1–2 tbsp to your iced latte.
- 2 shots espresso
- 1–2 tbsp lavender syrup
- 200ml oat milk over ice
Variation 5: Matcha Dirty Latte
The best of both worlds — matcha's earthy calm and coffee's bold energy in one glass.
- 1 tsp matcha whisked with 60ml hot water
- 1 shot espresso or 75ml cold brew
- 150ml oat milk over ice
- Pour matcha first, then milk, then coffee for a beautiful layered effect
Variation 6: Salted Caramel Cold Brew Latte
Rich, indulgent, and perfectly balanced between sweet and salty.
- 150ml cold brew concentrate
- 1 tbsp caramel sauce (stirred into concentrate)
- Pinch of flaky sea salt
- 150ml whole milk over ice
- Drizzle of caramel on top
Tips for the Best Iced Lattes
- Use large ice cubes — they melt slower and dilute less
- Brew coffee stronger than usual — ice dilutes flavor; compensate with a stronger concentrate
- Add sweetener to warm coffee — dissolves better than in cold milk
- Pour milk before coffee — creates a beautiful layered effect
