This looks like the ultimate, spoonable hybrid of a thick diner milkshake and a coffeehouse blended frappé. To get that incredibly dense, whipped texture that doesn't immediately melt into a watery mess, the secret is using a tiny pinch of xanthan gum and a high-quality protein powder.
This recipe delivers a rich, dessert-like treat that is entirely low-carb and sugar-free.
🍪 Low-Carb Chocolate Chip "Cookie Dough" Frappé
By using a gold/brown sugar alternative and vanilla, this shake takes on a nostalgic chocolate chip cookie dough flavor.
-
Prep time: 5 minutes
-
Yield: 1 large serving (as pictured)
Ingredients
For the Blended Frappé:
-
Unsweetened Almond Milk: 1 cup (or macadamia nut milk)
-
Heavy Whipping Cream: $\frac{1}{4}$ cup (adds that rich, velvety mouthfeel)
-
Vanilla Protein Powder: 1 scoop (whey isolate or a vegan blend works best for thickness)
-
Brown Sweetener: 1 tbsp gold/brown monk fruit sweetener or erythritol (for that cookie-dough-like brown sugar flavor)
-
Vanilla Extract: 1 tsp
-
Xanthan Gum: $\frac{1}{4}$ tsp (Do not skip this! This is what emulsifies the ice and liquid to create that ultra-thick, creamy texture)
-
Ice: $1\frac{1}{2}$ to 2 cups of ice cubes
For the Toppings:
-
Whipped Cream: A generous spray of sugar-free whipped cream
-
Chocolate: 1 tbsp sugar-free chocolate chunks or dark chocolate chips (such as Lily's)
Step-by-Step Instructions
1. Blend the Liquid and Powder
In a high-powered blender, combine the almond milk, heavy cream, vanilla protein powder, brown sweetener, vanilla extract, and xanthan gum. Blend on low for about 10 seconds just to combine the ingredients and dissolve the sweetener.
2. Add the Ice and Emulsify
-
Add the ice cubes to the blender.
-
Start blending on low, then gradually increase the speed to high.
-
Blend for 45 to 60 seconds. You will actually hear the motor change pitch as the xanthan gum kicks in, transforming the ice and liquid into a thick, aerated, soft-serve-like texture.
3. Assemble Your Masterpiece
-
Pour (or spoon, since it will be incredibly thick!) the frappé into a tall glass.
-
Top with a massive mound of sugar-free whipped cream.
-
Press a few sugar-free chocolate chunks into the whipped cream, slide in a wide straw, and enjoy immediately with a spoon!
💡 Pro-Tips for the Perfect Texture
-
The Blender Technique: If your blender has a tamper (the plastic stick used to push food down), use it to keep the ice moving into the blades. Because this shake is so thick, it can sometimes create an air pocket over the blades.
-
Make it Coffee-Flavored: If you prefer a classic coffee frappé, simply swap the 1 cup of almond milk for $\frac{1}{2}$ cup of cold brew coffee and $\frac{1}{2}$ cup of almond milk.
