Copycat Starbucks S’mores Frappuccino Recipe – Creamy, Chocolatey, and Easy

The Starbucks S’mores Frappuccino has a cult following for good reason: it tastes like summer in a cup. You get layers of creamy vanilla, rich chocolate, and toasted marshmallow flavor with a graham cracker crunch. The best part?

You can make a spot-on version at home with simple ingredients. It’s budget-friendly, customizable, and you don’t have to leave the house to get that nostalgic treat.

Why This Recipe Works

This copycat version mirrors the original by building flavor in layers. A sweet marshmallow-vanilla cream at the bottom sets the tone.

The blended coffee base gets chocolate and graham notes, and a drizzle of chocolate sauce ties everything together.

Using cold coffee or cold brew keeps the texture smooth and the flavor bold, without watering it down. Graham cracker crumbs add that campfire cookie crunch, and a quick “toasted” marshmallow whipped cream gives you the finish you’re craving—all with ingredients you can find at any grocery store.

What You’ll Need

• Cold coffee or cold brew: 3/4 cup, chilled
• Milk: 1/2 cup (whole milk for creaminess; use any milk you like)
• Ice: 1 1/2 to 2 cups
• Granulated sugar or simple syrup: 2–3 tablespoons (adjust to taste)
• Chocolate syrup: 2 tablespoons for the blend, plus extra for drizzling
• Graham crackers: 2 sheets, crushed (about 1/4 cup crumbs), plus extra for topping
• Vanilla extract: 1/2 teaspoon
• Marshmallow creme or fluff: 2 tablespoons (for the base)
• Whipped cream: 1 cup (store-bought or homemade)
• Mini marshmallows (optional): A handful for topping
• Pinch of salt: To balance sweetness

Special equipment: Blender, tall glass, spoon or spatula.

How to Make It

1. Prep the marshmallow base: In your serving glass, mix 2 tablespoons marshmallow creme with 2 tablespoons whipped cream and a few drops of vanilla. Spread it along the bottom and slightly up the sides. This creates the signature sweet, creamy layer.
2. Chill your glass (optional): Pop the glass in the freezer while you blend. A cold glass helps maintain clear layers and better texture.
3. Blend the coffee layer: In a blender, add cold coffee, milk, ice, chocolate syrup, sugar or simple syrup, vanilla, a pinch of salt, and 2 tablespoons graham cracker crumbs. Blend until thick and smooth. If it’s too thin, add more ice; too thick, add a splash of milk.
4. Layer with chocolate and graham: Drizzle chocolate syrup inside the glass over the marshmallow layer. Sprinkle a little graham crumb over the chocolate for texture.
5. Pour and top: Pour the blended mixture over the base. Top with a generous swirl of whipped cream, more chocolate drizzle, extra graham crumbs, and a few mini marshmallows if you like.
6. Optional “toasted” finish: Carefully torch the mini marshmallows with a kitchen torch until golden, or broil them on a lined sheet for 30–60 seconds and place on top.
7. Serve right away: Insert a wide straw and enjoy the layers in every sip.

Keeping It Fresh

Frappes are best right after blending.

If you need to make it ahead, blend the coffee base without ice and chill it for up to 24 hours. When ready, add ice and blend to finish.

You can prep components in advance: crush graham crackers and store in an airtight container, and stir together the marshmallow-vanilla base and refrigerate for up to 2 days. Whipped cream holds well for a few hours in the fridge, especially if stabilized with a spoonful of marshmallow creme.

Benefits of This Recipe

• Saves money: One homemade drink costs a fraction of the café version.
• Customizable sweetness: You choose how sweet and how chocolaty.
• Flexible for diets: Easy swaps for dairy-free, low-sugar, or caffeine-free versions.
• Made with pantry staples: No special syrups required, just simple ingredients.
• Consistent results: The layering trick and cold ingredients deliver a cafe-style texture every time.

What Not to Do

• Don’t use warm coffee: Warm liquid melts the ice and makes a thin, slushy drink.
• Don’t skip the salt: A tiny pinch sharpens flavors and tames sweetness.
• Don’t overblend: Running the blender too long turns the drink watery.Blend just until smooth and thick.
• Don’t load in dry crumbs at the end: Add most of the graham to the blend and reserve some for topping to avoid soggy bits.
• Don’t rely on only ice for thickness: Balance with milk and syrup for body; too much ice tastes icy, not creamy.

Variations You Can Try

• No-coffee version: Swap coffee for milk or chocolate milk. Add 1/2 teaspoon instant hot cocoa powder for extra chocolate flavor.
• Dairy-free: Use almond, oat, or coconut milk. Choose a dairy-free whipped topping and vegan marshmallow creme.
• Mocha-boost: Add 1 teaspoon unsweetened cocoa powder to the blender for a deeper chocolate note.
• Caramel s’mores: Drizzle caramel sauce in addition to chocolate and sprinkle sea salt on top.
• Protein-packed: Blend in 1/2 scoop vanilla or chocolate protein powder and reduce sugar slightly.
• Extra graham: Rim the glass with honey and dip into graham crumbs for a crunchy edge.
• Lightened-up: Use half the syrup, a stevia-based sweetener, and skim or unsweetened almond milk; add extra vanilla for flavor.

FAQ

Can I use instant coffee?

Yes.

Dissolve 1–2 teaspoons of instant coffee in 3/4 cup cold water. Chill it before blending to keep the texture thick and smooth.

What if I don’t have marshmallow creme?

Mix 1/2 cup whipped cream with 1 tablespoon powdered sugar and a splash of vanilla. It won’t taste exactly like marshmallow, but it mimics the sweet, fluffy base.

You can also melt a few mini marshmallows with a teaspoon of water in the microwave and cool slightly before using.

How do I make it thicker?

Use more ice and slightly less milk, or add a small handful of frozen milk cubes. A tablespoon of dry milk powder can also add body without extra water.

Can I make a large batch?

Yes. Scale the ingredients evenly and blend in batches so you don’t overload the blender.

Keep the first batch in the freezer for a few minutes while you blend the next.

What’s the best milk to use?

Whole milk gives the creamiest texture, but oat milk is a great dairy-free option with good body. Almond milk is lighter; coconut milk adds richness and a hint of coconut flavor.

Is there a way to toast marshmallows without a torch?

Place mini marshmallows on a parchment-lined sheet and broil 6–8 inches from the heat for 30–60 seconds, watching closely. Let them cool briefly, then add to your drink.

Can I make it less sweet?

Start with 1 tablespoon syrup and 1 tablespoon sugar, then taste and adjust.

Extra vanilla and a pinch more salt boost flavor without more sugar.

How do I prevent separation?

Blend until just smooth and serve immediately. Using cold ingredients and a chilled glass helps keep the layers stable for longer.
