Equipment

  • High-powered blender - Vitamix, Ninja, or similar model that handles frozen fruit best
  • Measuring cups
  • Measuring spoons
  • Tall serving glasses - 16 oz / 475ml capacity or larger
  • Reusable smoothie straws - Wide-mouth works best for thick smoothies (optional)
  • Rubber spatula - Useful for scraping down the sides of the blender (optional)
  • Fine-mesh strainer - For removing blackberry seeds if desired (optional)

Ingredients
  

  • 1 cup frozen strawberries - 150g
  • 1 cup frozen blackberries - 145g
  • 1 medium ripe banana - fresh or frozen, broken into chunks
  • 3/4 cup milk of choice - 180ml, dairy milk, almond milk, oat milk, or coconut milk
  • 1/2 cup Greek yogurt - 120g, plain or vanilla, full-fat recommended
  • 1 tablespoon honey - or pure maple syrup, adjust to taste
  • 1/2 teaspoon vanilla extract - pure, optional but highly recommended
  • 1 pinch salt - brings out the sweetness of the fruit

For topping (optional)

  • fresh strawberries - sliced
  • fresh blackberries
  • granola - for sprinkling
  • honey - drizzle

Instructions
 

  • Gather and measure all ingredients: 1 cup (150g) frozen strawberries, 1 cup (145g) frozen blackberries, one ripe banana (chunked), 3/4 cup (180ml) milk, 1/2 cup (120g) Greek yogurt, honey, vanilla, and salt.
  • Pour the milk into the blender first, then spoon in the Greek yogurt. Add the vanilla extract and pinch of salt at this stage. Adding liquid first protects the motor and helps everything blend evenly.
  • Drop the banana chunks into the blender on top of the yogurt, then add the frozen strawberries, followed by the frozen blackberries. Placing frozen items last helps them sit closer to the blades without straining the motor.
  • Drizzle 1 tablespoon of honey or maple syrup over the top of the fruit. If using very ripe berries, start with 1/2 tablespoon and taste after blending.
  • Secure the lid tightly, start on low speed for 5-10 seconds, then ramp up to high. Blend for 45-60 seconds until completely smooth with no visible chunks. If too thick, add an extra splash of milk (1-2 tablespoons) and blend again.
  • Taste and adjust: add more honey if needed, or brighten with a tiny squeeze of fresh lemon juice (about 1/2 teaspoon). For a thicker consistency, add a few more frozen berries and blend again for 20 seconds.
  • Pour into one or two tall glasses. Top with fresh strawberries, blackberries, or a sprinkle of granola if desired. Serve immediately while cold and thick.

Notes

  • Frozen fruit is key: Always use frozen strawberries and blackberries for the thickest, creamiest texture. Ice dilutes the flavor and thins out the smoothie.
  • Layer ingredients correctly: Always add liquids first, soft ingredients second, and frozen fruit last. This protects the blender motor and ensures even blending.
  • Blend long enough: Blackberries have small seeds that need full processing. Blend for a minimum of 45 seconds on high for the smoothest result.
  • Remove seeds if desired: If you're sensitive to blackberry seeds, pour the finished smoothie through a fine-mesh strainer before serving for a silky texture.
  • Adjust thickness: For a thicker smoothie, use a frozen banana instead of fresh, reduce the liquid to 1/2 cup (120ml), or add extra frozen berries. For a thinner smoothie, add more milk — never water.
  • Make it dairy-free: Swap the Greek yogurt for coconut yogurt and use unsweetened almond milk or oat milk. The result stays creamy and rich.
  • Add protein: Add one scoop of vanilla or unflavored protein powder and an extra splash of milk for a post-workout recovery drink.
  • Prep ahead: Portion the fruit (strawberries, blackberries, banana chunks) into zip-top freezer bags. Each morning, dump a bag into the blender, add liquid and yogurt, and blend.
  • Storage: Refrigerate leftovers in a sealed jar for up to 24 hours (stir before drinking) or freeze in containers for up to 3 months. Thaw overnight or blend from frozen with a splash of milk.
  • Nutrition tip: For lower sugar, omit the honey and use a very ripe banana as the sole sweetener. The natural sweetness will still satisfy.
