A Different Kind of Frappuccino (Coffee Frappé)
If you've ever longed for a frappuccino that actually keeps you full (and doesn't taste like a melted milkshake), this is for you. Think of it like a coffee drink that delivers a caffeine boost and qualifies as a light breakfast or snack thanks to 33 grams of protein!
Instant espresso gives it just enough bold coffee flavor. This also means you don't have to plan ahead to brew, chill, and freeze coffee.
Starbucks uses a base syrup that includes plenty of sugar, plus xanthan gum for emulsification. Instead, we're using protein powder for sweetness and body.
I also like to add a spoonful of peanut butter to make it richer and more filling. The roastiness of peanut butter and coffee are a surprisingly good pairing. Or you can customize your drink with other nut or seed butters, such as almond, walnut, sunflower seed, or pistachio butter!

Ingredients & Subs
- Instant espresso: Finally, an impulse purchase I don't regret! I'm using the Whole Foods 365 brand instant espresso. It comes in individual packets, which are handy, and the flavor is surprisingly good. Use any brand of instant espresso you like.
- Plant-based milk: I usually go with unsweetened soy or almond milk. Pistachio, cashew, coconut, or oat milk also taste great.
- Protein powder: I prefer vanilla-flavored protein since it doesn't compete too much with the coffee flavor. Orgain is my go-to brand. Note that many protein powders contain thickeners. If you use one that doesn't, your frappuccino will have a thinner consistency.
- Nut or seed butter: This adds fat and contributes both flavor and creaminess. I typically use peanut butter. Almond, pistachio, cashew butter, sunbutter, or tahini are also tasty options.
Variations
- Mocha (or Chocolate PB): Add 2 teaspoons cacao or cocoa powder or use chocolate protein.
- Vanilla Latte: Skip the peanut butter or swap it for cashew butter. Use a vanilla-flavored milk or add vanilla bean paste, extract, or powder to boost the flavor. A few milkshake cubes from my vegan milkshake recipe would be even better!
- Caramel: Add date caramel or other homemade caramel sauce to taste. Serve topped with whipped cream and caramel drizzle.
- Stronger coffee: Add more instant espresso, or replace some of the ice with frozen coffee cubes.
- Green Frappe (pictured below): Sometimes I like to add fresh greens to the blender, usually a "super greens" mix of mostly baby spinach and kale. The espresso completely disguises any "green" taste. Think of it like a green smoothie but with espresso instead of fruit!
- Extra creamy: Blend oats and/or cashews into the milk, or use a richer non-dairy milk or creamer (like soy or barista-style).
Toppings and Syrups
Want the full Starbucks Frappuccino experience (but homemade and healthier)?
👉Top your drink with coconut whipped cream or any non-dairy whip you love. Then add a drizzle of vegan chocolate sauce or date caramel sauce.
Bonus! Drizzle a little chocolate or caramel down the inside of your glass before filling.
Helpful Tips
- Measure the ice. It really matters here. Too much ice makes the frappuccino overly thick, then you need more milk, which dilutes the flavor. Too little ice and it won't get that thick, frosty texture. As written, about 5 ounces of ice is just right.
- Use a protein powder you enjoy. It provides both sweetness and flavor, so vanilla works especially well.
- Note the ingredients. Some protein powders contain gums and added fiber. If your protein powder doesn't, your frappe will have a slightly thinner consistency. See the Variations section above for ways to make it thicker.
- Adjust to taste. Depending on your protein powder, you may want a touch more sweetness. A date, spoonful of sugar, or drizzle of maple syrup blends in easily.
- Start with less milk if unsure. You can always add more after blending to reach your ideal consistency.
- Enjoy right away. Like any blended iced drink, the texture is at its peak right after blending.

This is AMAZING! What a great idea. I used the 365 instant espresso and it turned out so good! Thanks so much!
Judy says
Looking forward to trying this! Question: How much (measured) is “1 serving of instant espresso “?
Lori Rasmussen says
Thanks, Judy. Glad it looks good to you! The volume will depend on the product and size of the granules, since some are more powdered than others. The one I have is coarse and looks like instant coffee. Each serving is 3 grams and a bit less than 1 tablespoon.
