Ingredients Method

Ingredients
  

  • 1 cup ice (crushed if your blender is weaker)
  • 1/2 cup cold brew coffee (or strong chilled coffee; decaf works too)
  • 3/4 cup unsweetened almond milk (or unsweetened macadamia milk)
  • 1–2 tablespoons heavy cream (or full-fat coconut milk for dairy-free)
  • 1 scoop caramel or vanilla whey isolate (or plant-based low-carb protein)
  • 1–2 teaspoons keto caramel syrup (or 1–2 teaspoons allulose/erythritol plus 1/4 teaspoon caramel extract)
  • 1/4 teaspoon vanilla extract
  • Pinch of sea salt (enhances caramel flavor)
  • Optional boosters: 1 tablespoon MCT oil or almond butter, 1/4 teaspoon xanthan gum for extra thickness, a few drops liquid stevia if you like it sweeter
  • Optional topping: Sugar-free whipped cream and a drizzle of keto caramel syrup

Method
 

  1. Chill your liquids: Use cold brew and cold almond milk so the smoothie stays thick and icy.
  2. Add liquids first: Pour in almond milk, cold brew, and heavy cream. Adding liquids first helps the blades pull in the solids smoothly.
  3. Add powders and flavor: Drop in the protein powder, caramel syrup (or sweetener + extract), vanilla, and sea salt.
  4. Boost if desired: Add MCT oil or almond butter for richness and staying power. Sprinkle in xanthan gum if you prefer a café-thick texture.
  5. Top with ice: Add the ice last so it blends evenly without clumping.
  6. Blend until frosty: Start low, then increase to high for 20–30 seconds. Stop and scrape the sides if needed. Aim for a thick, shake-like consistency.
  7. Taste and adjust: If you want it sweeter, add a couple drops of stevia and pulse. If it’s too thick, splash in more almond milk; too thin, add a bit more ice.
  8. Serve immediately: Pour into a tall glass, add whipped cream and a caramel drizzle if using, and enjoy while it’s cold and frothy.
