Ingredients Method

Ingredients
  

  • 1 cup unsweetened almond milk (or unsweetened coconut milk for extra richness)
  • 2 tablespoons natural peanut butter (no added sugar)
  • 1/2 cup frozen cauliflower florets or 1/4 medium avocado (for creaminess)
  • 1/2 teaspoon banana extract (adjust to taste)
  • 1 scoop vanilla or unflavored low-carb protein powder (optional, for protein)
  • 1–2 teaspoons powdered erythritol, monk fruit, or allulose (to taste)
  • 1 tablespoon MCT oil or 2 tablespoons canned full-fat coconut milk (optional, for extra fat and creaminess)
  • 1/2 teaspoon vanilla extract (optional, for warmth and depth)
  • Pinch of cinnamon and a tiny pinch of salt (optional, enhances flavor)
  • 1/2–1 cup ice (adjust for thickness)

Method
 

  1. Prep your base: Add unsweetened almond milk to the blender first. Liquids at the bottom help everything blend smoothly.
  2. Add the creaminess: Toss in the frozen cauliflower or avocado. Cauliflower keeps carbs lower and adds bulk without flavor. Avocado gives ultra-smooth texture.
  3. Flavor it up: Add peanut butter, banana extract, vanilla extract, cinnamon, and a tiny pinch of salt. The salt makes the peanut butter pop.
  4. Boost as needed: Add protein powder if you want more staying power. Include MCT oil or coconut milk for a richer, more filling smoothie.
  5. Sweeten to taste: Start with 1 teaspoon of your preferred keto sweetener. You can always add more later.
  6. Blend with ice: Add ice and blend on high until creamy and smooth, about 30–60 seconds. If it’s too thick, add a splash more almond milk. If it’s too thin, add a few more ice cubes.
  7. Taste and adjust: Take a sip. If you want stronger banana flavor, add a few more drops of extract. Adjust sweetness or salt if needed.
  8. Serve: Pour into a chilled glass. For a finishing touch, dust with a little cinnamon or add a few crushed peanuts on top.
