Let's be honest – half the people ordering lavender cold foam do it for the purple Instagram photo. The other half genuinely love the floral, slightly sweet flavor. Very few people sit in the middle. You'll either think this tastes sophisticated and spring-like, or you'll swear you're drinking perfume. There's not much room for "meh."
Reality check: at $6+ per drink, you shouldn't have to gamble. Make it at home, experiment with the lavender intensity, and figure out if you're team lavender or team "why does my coffee taste like soap" without dropping $60 finding out.
This guide covers how to make lavender cold foam three ways (syrup, extract, or powder), whether the purple color actually matters, five different methods to froth it, and what drinks this works on beyond just matcha lattes.
What Lavender Cold Foam Actually Is
Lavender cold foam is frothed milk and cream flavored with lavender (usually via syrup) and often tinted purple for the aesthetic. It's the same base as vanilla sweet cream cold foam, just with lavender instead of vanilla and optional purple food coloring to make it Instagram-ready.
The basics:
- Heavy cream + milk base (for richness and texture)
- Lavender flavoring (syrup, extract, or powder)
- Optional purple coloring (food dye or natural alternatives)
- Frothed until thick and pourable
What you're getting:
- Floral, slightly sweet topping for iced drinks
- A gorgeous purple layer (if you care about that)
- Sophisticated spring/summer flavor
- Something that costs $0.50 at home vs $6+ at cafés
Real talk: Lavender is polarizing. Some people love it. Some people think it tastes like hand soap or their grandmother's perfume. If you've never had lavender in food or drinks before, maybe don't make a huge batch your first try.
The Quick Method (5 Minutes, Lavender Extract)
This is the easiest way if you don't want to make lavender syrup from scratch. Uses lavender extract you can find at most grocery stores or online.
What you need:
- ¼ cup heavy cream
- 2 tablespoons whole milk (or 2% milk)
- 1 tablespoon vanilla syrup or simple syrup
- ¼ teaspoon lavender extract (start small, it's strong)
- 2-3 drops purple food coloring (optional, for the look)
- Tiny pinch of salt
How to make it:
-
Combine everything – Add all ingredients to a tall glass or measuring cup. Start with less lavender extract – you can always add more but you can't take it out.
-
Taste test – Dip a spoon in before frothing. Too much lavender = perfume vibes. Too little = just sweet vanilla foam. Adjust if needed.
-
Froth it – Use handheld frother for 20-30 seconds until thick and foamy. Keep frother just under the surface.
-
Check color – If you want that purple Instagram look, add food coloring before frothing so it mixes in evenly.
-
Use immediately – Spoon over your iced drink right away.
Pro tip: Lavender extract is concentrated. A little goes a long way. Start with ¼ teaspoon and increase to ½ teaspoon max if you want it stronger.
The Syrup Method (Best Flavor Control)
This gives you the most control over lavender intensity and makes enough syrup to last weeks. It's the method most similar to what Starbucks actually does.
For lavender simple syrup (makes about 1 cup):
- 1 cup water
- 1 cup sugar
- 2-3 tablespoons dried culinary lavender buds (not potpourri lavender)
- ½ teaspoon vanilla extract
- Optional: 1 tablespoon butterfly pea flowers or blueberry juice for natural purple color
For the cold foam:
- ¼ cup heavy cream
- 2 tablespoons milk
- 1-2 tablespoons lavender syrup
- Pinch of salt
How to make it:
Step 1: Make lavender syrup
- Bring water and sugar to a boil, stirring until sugar dissolves
- Remove from heat, add lavender buds (and butterfly pea if using)
- Steep 10-15 minutes (longer = stronger flavor)
- Strain out lavender buds through fine mesh strainer
- Stir in vanilla extract
- Let cool completely, then refrigerate (keeps 3-4 weeks)
Step 2: Make the cold foam
- Mix heavy cream, milk, lavender syrup, and salt
- Froth for 20-30 seconds until thick and foamy
- Add food coloring if desired (natural purple from syrup or add drops)
- Use immediately on your drink
Smart move: Make a big batch of lavender syrup. It keeps for weeks and you can use it in other drinks, cocktails, or even drizzle on pancakes.
The Powder Method (Most Like Starbucks)
Starbucks actually uses lavender powder, not syrup, in their seasonal drinks. This method is more involved but creates the most authentic copycat.
For lavender powder (makes about ¼ cup):
- 3 tablespoons dried culinary lavender buds
- 2 tablespoons black currant powder (for purple color) or purple sweet potato powder
- Optional: ½ teaspoon soy lecithin powder (prevents clumping)
For the cold foam:
- ¼ cup heavy cream
- 2 tablespoons milk
- 1½ tablespoons vanilla syrup
- ½ teaspoon lavender powder
- Pinch of salt
How to make it:
Step 1: Make lavender powder
- Grind lavender buds in spice grinder or coffee grinder until fine powder
- Mix with black currant powder (or other purple coloring)
- Add soy lecithin if using
- Store in airtight container (keeps 3+ months)
Step 2: Make the cold foam
- Mix all ingredients in a glass
- Froth for 30-40 seconds until thick (powder takes longer to incorporate)
- Use immediately
Real talk: This method is overkill unless you're making lavender drinks multiple times a week or you really want it exactly like Starbucks. For most people, the syrup or extract method works just fine.
5 Ways to Froth Lavender Cold Foam
Method 1: Handheld Frother (Best Option)
What you need: $10 handheld milk frother
How: Pour ingredients into tall glass, froth for 20-30 seconds just under surface.
Best for: Daily use, easy cleanup, works every time.
Pro tip: Lavender syrup is thicker than regular syrup, so you might need an extra 5-10 seconds of frothing.
Method 2: French Press (No Equipment)
What you need: French press
How: Add ingredients (fill ⅓ max), pump plunger vigorously 40-50 times until doubled in volume.
Best for: When you don't want to buy more gadgets.
Downside: Takes more effort. Foam isn't quite as stable.
Method 3: Mason Jar Shake (Arm Workout)
What you need: Mason jar with tight lid
How: Fill halfway with ingredients, seal tight, shake aggressively 45-60 seconds.
Best for: Proving a point when you have no equipment.
Real talk: This works but it's exhausting and the foam settles fast. Just buy a $10 frother.
Method 4: Electric Milk Frother (Hands-Free)
What you need: Electric milk frother with cold foam setting
How: Add ingredients, press cold foam button, wait.
Best for: If you already own one (Nespresso Aeroccino, etc.).
Downside: Overkill for most people. Costs $80-150.
Method 5: Immersion Blender (Fast But Messy)
What you need: Immersion blender, tall container
How: Blend on low then increase speed, 15-20 seconds total.
Best for: Making foam fast if you own an immersion blender.
Warning: Easy to over-blend and make lavender whipped cream. Watch it carefully.
The Purple Color Question (Does It Actually Matter?)
Did you know: lavender is naturally light brown/tan when steeped. That gorgeous purple you see at Starbucks? Food coloring or natural colorants. So you have options:
Option 1: Artificial food coloring – 2-3 drops purple gel or liquid food coloring. Gets you that vibrant Instagram purple. Works instantly.
Option 2: Butterfly pea flowers – Steep with lavender in syrup. Creates natural blue-purple color. Looks cool, tastes neutral.
Option 3: Berry juice – Add a splash of blueberry or blackberry juice. Natural purple, adds slight berry undertone.
Option 4: Purple sweet potato powder – Mix into foam. Natural purple, subtle earthy flavor.
Option 5: Skip the color entirely – Your foam will be cream-colored. Still tastes the same.
Real talk: The purple is mostly aesthetic. It doesn't affect flavor. If you're making this for yourself and don't care about Instagram, skip the coloring. If you want that Starbucks look, purple food coloring is the easiest route.
Best Milk Choices for Lavender Cold Foam
Heavy cream – Makes the richest, most stable foam. Best texture, best flavor.
Whole milk – Good for lighter version. Still froths well.
2% milk – What Starbucks uses with heavy cream. Balanced option.
Half-and-half – Richer than milk, lighter than cream. Great middle ground.
Oat milk – Best non-dairy option. Froths almost as well as dairy.
Almond milk – Doesn't froth great on its own. Use barista blends if you must.
Pro tip: For best results, use heavy cream + 2% milk combo (the Starbucks ratio). For dairy-free, use oat cream or coconut cream.
Why Your Lavender Cold Foam Tastes Like Soap
This is the most common complaint. Here's why it happens and how to fix it:
Problem: Tastes like perfume/soap/hand lotion
What's happening: Too much lavender, or you used the wrong kind of lavender.
Fix:
- Use CULINARY-GRADE dried lavender, not potpourri or craft store lavender
- Cut lavender amount in half
- Add more vanilla to balance the floral notes
- Make sure you're not steeping too long (max 15 minutes for syrup)
Problem: Too floral, overwhelming
What's happening: Lavender intensity is too high.
Fix:
- Start with less lavender extract/syrup and build up
- Add a squeeze of lemon juice to cut the floral notes
- Mix in some vanilla syrup to mellow it out
Problem: Tastes bitter
What's happening: Over-steeped lavender or burned the syrup.
Fix:
- Don't steep lavender longer than 15 minutes
- Don't boil lavender directly (steep after removing from heat)
- Strain thoroughly to remove all buds
Problem: No lavender flavor at all
What's happening: Not enough lavender or old/stale lavender buds.
Fix:
- Use fresh culinary lavender (check expiration date)
- Increase lavender amount gradually
- Make sure you're using actual lavender, not just calling it lavender
Pro tip: If you're trying lavender for the first time and worried about the soap taste, start with half the lavender called for. You can always add more, but you can't take it out.
What Drinks to Put Lavender Cold Foam On
Iced matcha latte – The Starbucks original. Earthy matcha + floral lavender = surprisingly good.
Iced coffee – Strong cold brew with lavender foam. Classic combo.
Iced latte – Espresso + milk + lavender foam. Smooth and sophisticated.
Iced chai – Spicy chai + floral lavender. Complex and interesting.
Iced earl grey – Tea on tea action. Bergamot + lavender = very British, very fancy.
Cold brew – Simple black coffee, lavender foam on top. Let the lavender shine.
Iced vanilla latte – If straight lavender is too much, vanilla base helps mellow it.
Lemonade – Weird but it works. Tart lemon + sweet lavender = refreshing.
Sparkling water – For non-coffee people. Actually pretty good.
Making It Your Own
Honey lavender cold foam – Replace some syrup with honey. Add lemon zest. Very spring, very fresh.
Lavender vanilla cold foam – Equal parts lavender and vanilla syrup. More balanced, less polarizing.
Lavender cinnamon cold foam – Add ¼ teaspoon cinnamon. Warm and cozy.
Lemon lavender cold foam – Add ½ teaspoon lemon zest to syrup. Bright and citrusy.
Lavender rose cold foam – Add a few drops rose water. Full flower power (proceed with caution).
Less intense version – Use lavender extract instead of syrup, cut amount in half.
Dairy-free version – Use oat cream or coconut cream instead of heavy cream.
Storage and Make-Ahead Tips
Lavender syrup: Keeps 3-4 weeks refrigerated in airtight container. Make a big batch, use all month.
Lavender powder: Keeps 3+ months in airtight container in cool, dry place. Doesn't clump if you add soy lecithin.
Mixed but unfrothed ingredients: Keeps 2-3 days refrigerated. Froth right before using.
Already frothed foam: Use immediately. Deflates within 10-15 minutes.
Dried lavender buds: Keep 1-2 years in airtight container away from light. Smell them – if no scent, they're too old.
Pro tip: Freeze leftover lavender syrup in ice cube trays. Pop a cube into drinks when you want lavender flavor without making fresh syrup.

Questions People Always Ask
Does lavender cold foam actually taste like lavender or just purple vanilla? Depends how much you use. Done right, it should taste floral and distinctly lavender. If it just tastes like vanilla, you didn't use enough lavender.
Why does everyone put this on matcha specifically? Starbucks started it with their viral lavender matcha drink. The earthy matcha balances the floral lavender. But it works on lots of drinks.
Do I HAVE to use purple food coloring? Nope. Lavender tastes the same whether it's purple or cream-colored. The purple is just for looks.
What if I think lavender tastes like soap? You're not alone. Try using way less lavender, or add lemon and vanilla to balance it. Or maybe lavender just isn't your thing – that's okay.
Can I use lavender essential oil? NO. Essential oils are not food-grade and can be toxic if ingested. Use culinary lavender, lavender extract, or food-grade lavender flavoring only.
Where do I buy culinary lavender? Amazon, specialty spice stores, farmers markets, or bulk spice shops. Make sure it says "culinary grade" or "food grade."
How much caffeine is in lavender cold foam? None. The foam itself has no caffeine. The drink underneath might.
Can I make this without any special ingredients? If you can find lavender extract at your grocery store, yes. Otherwise you need to order culinary lavender to make syrup.
Will this keep me awake? Lavender is actually calming/relaxing. The caffeine in your coffee will keep you awake, not the lavender.
What's the difference between lavender cold foam and lavender cream cold foam? Same thing. "Cream" just emphasizes it's made with heavy cream, not just milk.
What to Do With Leftover Lavender
You bought 4 oz of culinary lavender for this recipe and used 2 tablespoons. Now what?
Make more lavender syrup – It keeps for weeks. Having it on hand means you can make lavender drinks anytime.
Lavender sugar – Mix dried lavender with sugar, let sit 2 weeks. Use in baking or to rim cocktail glasses.
Lavender tea – Steep 1 teaspoon dried lavender in hot water. Add honey. Very calming.
Lavender lemonade – Add lavender syrup to lemonade. Surprisingly good.
Baking – Add to shortbread cookies, pound cake, or sugar cookies.
Lavender honey – Steep lavender buds in warm honey for 2 weeks. Strain. Use on toast or in tea.
Sachets – If you really can't use it all in food, make lavender sachets for drawers. At least you got some use out of it.
The Real Talk
Lavender cold foam is one of those things that's either your new obsession or a hard pass. The flavor is polarizing, the purple color is mostly for show, and half the appeal is the Instagram aesthetic. But if you like floral flavors, it's actually pretty sophisticated and interesting.
The best part about making it at home is you control the lavender intensity. Too strong and it tastes like perfume. Too weak and it's just sweet vanilla foam. When you dial it in right, it's a legitimately good spring/summer drink topping.
At $6+ per drink at Starbucks, figuring out if you even like lavender gets expensive fast. Make it at home for 50 cents, experiment with the flavor, and decide if you're team lavender without breaking the bank.
Ready to try something different? Start with making a great batch of cold brew, top it with lavender cold foam (go light on the lavender first try), and see if you're into the floral life or not.
