Ingredients

  • 1 cup frozen or fresh fruit of choice (e.g., berries, banana, mango)
  • 1 cup liquid (unsweetened almond milk, coconut milk, or water)
  • 1 tbsp nut butter (almond, peanut), chia seeds, or certified gluten-free protein powder
  • 0.5 tsp pure vanilla extract
  • 1 tbsp honey or pure maple syrup (optional, for added sweetness)
  • 1 cup ice cubes

Instructions

  1. 1

    Combine the frozen or fresh fruit, your chosen liquid, nut butter or chia seeds, pure vanilla extract, and optional honey or maple syrup into the pitcher of a high-speed blender. Ensure all ingredients are added before proceeding to the next step.

  2. 2

    Add the ice cubes to the blender pitcher, filling it to the appropriate level for your desired thickness. Secure the lid tightly and blend on high speed for approximately 60 to 90 seconds, or until the mixture is completely smooth and has a uniform, creamy consistency.

  3. 3

    Carefully taste the shake to assess its sweetness. If you prefer a sweeter beverage, add an additional teaspoon of honey or maple syrup and blend for another 15 seconds to incorporate.

  4. 4

    Pour the blended shake into two serving glasses. Serve immediately to enjoy its refreshing chill and smooth texture.

  5. 5

    For a thicker smoothie bowl consistency, reduce the amount of liquid by half and blend until thick and spoonable. Top with certified gluten-free granola, fresh fruit slices, and a sprinkle of seeds for added texture and flavor.

Tips & Notes

  • Brown the butter before adding it for a nutty, caramel depth that elevates simple recipes.
  • Any plant-based milk works here — oat milk (certified GF) gives the richest mouthfeel; almond milk keeps it lighter.
  • Freeze overripe bananas in their peel; thaw on the counter and squeeze out the pulp for perfectly soft mash.
