    Lavender is the floral flavor independent coffee shops keep putting on the menu — our Lavender Latte is built on a real culinary-lavender syrup, and this blends that same syrup with espresso, milk, and ice into a proper frappé.

    Make the Syrup First (Just Once)

    This recipe assumes you already have a jar of Lavender Syrup in the fridge — it keeps about 2 weeks and makes roughly 12 drinks’ worth. If you haven’t made a batch yet, go do that first, then come back here.

    Building the Frappé

    1. Pull a double shot of espresso (about 2oz), or brew strong coffee/cold brew instead.
    2. Add the espresso, 2 tbsp of the lavender syrup, 1.5 cups of ice, and 4oz cold milk to a blender.
    3. Blend on high for 30-45 seconds until smooth and slushy.
    4. Pour into a 16oz glass, top with whipped cream and a few dried lavender buds if using, and serve immediately with a straw.
    Café Lavender Frappé vs. Home Version
    Café grande lavender-style Frappuccino blended drink (specialty-café pricing)$6.45
    Home lavender frappé (espresso, milk, ice, syrup)~$0.58
    Savings per drink$5.87

    The syrup batch itself is a one-time ~$0.70 and makes about 12 drinks — see the full syrup recipe for the batch method. Same batch also covers the hot/iced latte version.

    Assumptions: grande-size blended drink, specialty-café pricing for a floral flavor found more at independent shops than big chains, dairy milk, $16/lb specialty beans or equivalent grocery beans. No seasonal ceiling — at 5 a week over the site’s standard 48-week year, that’s roughly $1,409/year back in your pocket versus the café version.

    Swaps & Notes

    • Use culinary-grade lavender only. Decorative/craft-store lavender may be treated with pesticides not meant for consumption — the syrup recipe specifies culinary-grade buds for exactly this reason.
    • No espresso machine? Strong cold brew or a moka pot shot both work fine.
    • Want it paired with white chocolate? See our Lavender White Mocha Latte in latte form — we haven’t built the frappé version of the combo yet.
    • Watching sugar? This is Standard-tier only for now. Blend the Sugar-Free Lavender Latte iced with ice yourself for a lower-sugar version today.

    FAQ

    Will this taste like soap?

    Not if the syrup is made right — a light steep with culinary lavender reads as floral and slightly sweet, not perfumed. Over-steeping (or using too much lavender) is what pushes it toward “soapy,” which is why the syrup recipe is specific about steep time and quantity.

    Can I make this without a blender?

    The iced Lavender Latte uses the same syrup poured over ice instead of blended.

    Is this a caffeinated drink?

    Yes, as written — it includes 2oz of espresso, same as our other flavored frappés. There isn’t currently a decaf or no-coffee version of this specific flavor on the site.
