How to make the Iced Vanilla Cream Protein Latte

Start by mixing unflavored whey isolate with cold milk and vanilla syrup to make a smooth, protein-rich latte base. Then whip up a quick cold foam using 1% milk and a bit more whey isolate plus vanilla syrup until thick and glossy. Pour the espresso over ice, add the protein milk, and finish with a swirl of protein cold foam.

Every sip gives you that velvety Starbucks café feel, but with over 25 grams of protein and none of the extra sugar.

Latte Base:

• 2 shots espresso (or ½ cup strong brewed coffee, cooled)
• ¾ cup 2% milk, cold
• 1 tablespoon vanilla syrup (sugar-free or classic)
• 1 tablespoon unflavored whey isolate (about 12 g)
• Ice (enough to fill a 16 oz glass)

Vanilla Protein Cold Foam:

• ¼ cup 1% milk, ice cold
• 2 teaspoons unflavored whey isolate (about 6 g)
• ¾ teaspoon vanilla syrup
• Pinch of salt (optional, for flavor depth)

Tools You’ll Need

• Milk frother or handheld electric whisk
• Espresso machine or strong coffee maker
• Shaker bottle or mason jar (for mixing protein)
• Measuring spoons and cups
• Tall glass (16 oz)
• Straw and long spoon

Instructions

Step 1: Make the Protein Milk Base

In a shaker bottle or mason jar, combine the ¾ cup cold milk with 1 tablespoon whey isolate and 1 tablespoon vanilla syrup. Shake vigorously for 10–15 seconds until smooth. Set aside.

Step 2: Pull the Espresso

Brew 2 shots of espresso (about 2 ounces total). If you’re using brewed coffee instead, let it cool completely before assembling.

Step 3: Build the Latte

Fill your 16 oz glass with ice. Pour the espresso over the ice. Then slowly add the protein milk base. Leave about 1–1½ inches of space at the top for the cold foam.

Step 4: Whip the Cold Foam

In a small cup or jug, mix ¼ cup cold 1% milk, 2 teaspoons whey isolate, ¾ teaspoon vanilla syrup, and an optional pinch of salt. Froth with a handheld frother for 15–30 seconds until you get soft, glossy foam.

Step 5: Top and Serve

Spoon or pour the cold foam over the drink. Serve immediately with a straw and enjoy your protein-packed, Starbucks-style sip.

Tips

• Chill your glass beforehand for a longer-lasting iced drink.
• Use really cold milk for the foam. It helps trap smaller air bubbles for that signature velvety texture.
• Don’t over-froth your cold foam. Stop once it thickens but still pours slowly.
• If using coffee instead of espresso, reduce the syrup slightly, coffee can taste more bitter than espresso.
• For extra creaminess, add a splash of half-and-half to the milk base.

What to Serve With

Light + Crunchy

• Rice cakes with almond butter: A mild, crisp texture that lets the vanilla latte shine. Try it with sliced banana on top for a subtle sweetness.
• Greek yogurt and berries: A cool, protein-rich snack that mirrors the drink’s vibe. Add a drizzle of honey and chia seeds to round it out.
• Sliced apple with cinnamon: Sweet and spiced, this is a great companion to a chilly protein latte. Think café autumn, but all year long.

Sweet Treats

• Vanilla bean scones: The soft crumble and sweet glaze make these perfect with the cold foam topper.
• Mini protein donuts: If you’re keeping a high-protein day going, grab a baked protein donut on the side. Double the protein, double the joy.
• Peanut butter energy balls: Dense, chewy, and lightly sweet, they give a nutty contrast to the icy smooth latte.

Savory Counterbalance

• Cheddar egg bites: Salty, eggy, and rich enough to balance out the sweetness. Like a mini brunch in a cup and a bite.
• Avocado toast: Lightly salted, creamy avocado with everything bagel seasoning on toast goes surprisingly well with vanilla lattes.
• Turkey bacon wrap: Lean, savory protein wrapped up tight. It’s a clean match for the high-protein drink and works great for breakfast on the go.

Variations

Sugar-Free Iced Protein Latte
Use sugar-free vanilla syrup in both the milk base and foam. Keeps carbs around 10 g and still tastes indulgent.

Hot Vanilla Protein Latte
Steam the protein-boosted milk base gently (to no more than 150°F) and top with warm frothed foam. Don’t overheat the whey or it may clump.

Chocolate Protein Latte
Swap the vanilla syrup for chocolate syrup and add a dash of cocoa powder to the foam. Tastes like a mocha milkshake in latte form.

Caramel Cold Foam Version
Use sugar-free caramel syrup in place of vanilla in both parts. The caramel flavor plus espresso makes this taste like dessert.

Protein Boost Only (No Foam)
If you’re short on time, skip the cold foam and just shake whey into milk with espresso. Still gives you 20+ g of protein, fast.

Protein Cold Brew Twist
Substitute espresso with cold brew coffee and use the same milk base and cold foam. Chill it extra cold for the best texture.

Ingredient Substitutes

Espresso
