Equipment

  • High Speed Blender

Ingredients
  

  • 2/3 cup brewed coffee, cooled 160 ml Provide cooled brewed coffee to form the flavorful liquid base and deliver caffeine and rich coffee aroma; allows the smoothie to blend smoothly without melting the ice too quickly. Use measured volume to control strength and overall drink temperature for a balanced keto beverage.
  • 2 tablespoon collagen peptides 14 g Add collagen peptides to contribute protein and support skin, hair, and joint health while remaining flavor-neutral; dissolves easily in cold liquids when blended. Include the specified amount to boost satiety and increase the smoothie’s nutritional profile without adding carbs.
  • 1 tablespoon peanut butter 30 g Incorporate peanut butter to add creamy texture, healthy fats, and a nutty flavor that enhances richness; contributes calories and satiety suitable for a keto diet. Choose smooth or stirred natural peanut butter for consistent mouthfeel and to avoid added sugars.
  • 1/4 cup coconut milk from a can, 60 g Pour coconut milk from a can to provide rich saturated fats and a silky mouthfeel that mimics dairy creaminess; contributes subtle coconut flavor and caloric density for keto-friendly energy. Use canned variety for thickness and a stable emulsion that blends well with cold coffee.
  • 4 oz Ice cubes 120 g (6 ice cubes) Include ice cubes to chill and thicken the smoothie while diluting intensity for a refreshing consistency; control number of cubes to adjust thickness and temperature. Use measured weight or count to maintain reproducible texture.
  • 1 teaspoon vanilla extract optional Add vanilla extract to impart aromatic sweetness and complex flavor notes that round out bitter coffee and nutty peanut butter; enhances perceived sweetness without sugar. Use sparingly to avoid overpowering other flavors and to keep the profile balanced.
  • 1 tablespoon powdered sweetener optional, to taste Mix powdered sweetener to tailor sweetness without adding carbs and maintain keto compliance; adjust quantity to taste for desired sweetness level. Choose a preferred low-carb powdered sweetener to dissolve well and avoid grainy texture.

Instructions
 

  • Place all ingredients in a high speed blender and blitz until smooth.: As the blender starts, you will hear a steady whirl that becomes smoother as the ice cubes break down and the peanut butter disperses. Visually look for a uniform, glossy texture with no streaks of coconut milk or clumps of collagen peptides . The aroma should shift from just coffee to a warm nutty scent. This rapid blending helps emulsify fats and liquids so the drink stays cohesive. If you underblend, you will feel graininess or small bits of nut; overblending can warm the drink slightly, so aim for about 20 to 40 seconds depending on blender power. A common mistake is starting on low speed which can leave peanut butter unincorporated, so pulse briefly then increase to full power.
  • Option to sprinkle with a little cacao before serving.: When you finish blending, the surface should be creamy and slightly frothy, and adding a small dusting of cacao introduces a bitter chocolate note and an attractive finish. The scent of cacao pairs with the roasted brewed coffee to create complexity, and the powder will rest on the foam for a pleasing presentation. Avoid dumping too much cacao which can clump; use a fine sieve or shaker for an even dusting. If you skip it, the smoothie will still taste complete, but the visual and bitter contrast will be missing.

Notes

  • Net carbs note: The recipe yields about 4.8g net carbs per portion based on the listed ingredients; this makes it a reliable low carb choice for mornings or snack times without busting daily limits.
  • Volume and serving size: This makes one large 300 ml smoothie, which I find fills a generous glass; if you want two smaller portions, divide the ingredients and blend separately for best texture.
  • Heavy cream swap: Swapping coconut milk for heavy cream reduces net carbs further to approximately 4.1g, and it produces a noticeably richer, silkier mouthfeel if you prefer more indulgence.
  • Sweetener preference: I usually keep my brewed coffee unsweetened and add powdered sweetener only to taste; powdered forms dissolve more cleanly than granulated sweeteners in cold liquids.
  • Vanilla for depth: A teaspoon of vanilla extract adds a mellow, rounded sweetness that complements the peanut butter and coffee, especially when you want a dessert like flair without extra carbs.
