Description

This creamy peanut butter smoothie is a protein-packed, naturally sweetened breakfast or snack that tastes like a milkshake but fuels your body with wholesome nutrition. Ready in just 5 minutes with simple pantry ingredients!


Ingredients

Scale
  • 2 tablespoons creamy peanut butter (natural or regular)
  • 1 large ripe banana (fresh or frozen)
  • 1 cup milk (dairy or non-dairy such as almond, oat, or soy milk)
  • 1 tablespoon honey or maple syrup (optional, adjust to taste)
  • 1 cup ice cubes (reduce if using frozen banana)
  • Optional: 1/4 cup Greek yogurt for extra protein
  • Optional: 1 tablespoon chia seeds or flax seeds
  • Optional: 1 teaspoon vanilla extract
  • Optional: 1 tablespoon cocoa powder for chocolate version


Instructions

Step 1: Prepare Your Ingredients
Peel and slice the banana if using fresh. Measure out your peanut butter, milk, and any optional add-ins. If using frozen banana, you can add it directly from the freezer.

Step 2: Add Ingredients to Blender
Add ingredients to your blender in this order for best blending: liquid (milk) first, then peanut butter, banana, sweetener, and ice cubes on top. This layering helps the blender blades work more efficiently.

Step 3: Blend Until Smooth
Blend on high speed for 30-60 seconds until completely smooth and creamy. Stop and scrape down the sides with a spatula if needed, then blend for another 15-20 seconds. The smoothie should be thick, creamy, and free of any ice chunks.

Step 4: Check Consistency
If your smoothie is too thick, add a splash more milk and blend again. If it’s too thin, add a few more ice cubes or another frozen banana chunk and blend until desired consistency is reached.

Step 5: Taste and Adjust
Give it a quick taste. Add more sweetener if needed, or a pinch of salt to enhance the peanut butter flavor. Blend briefly to incorporate any additions.

Step 6: Serve Immediately
Pour into a tall glass, add a straw, and enjoy right away for the best texture and temperature. Smoothies are best consumed fresh but can be stored if needed.

Notes

  • For Meal Prep: Freeze pre-portioned smoothie packs with sliced banana, measured peanut butter portions, and any dry add-ins in freezer bags. When ready, dump contents into blender with milk and ice, then blend.
  • Thickness Control: The key to a thick smoothie is using frozen fruit and less liquid. Start with less milk than you think you need—you can always thin it out.
  • Protein Boost: Add a scoop of protein powder, Greek yogurt, or silken tofu for extra protein without changing the flavor significantly.
  • Nut-Free Version: Substitute peanut butter with sunflower seed butter or tahini for schools and allergen-free environments.
  • Make it Vegan: Use plant-based milk, maple syrup instead of honey, and skip any dairy-based protein additions.
