A thick, creamy smoothie bowl made with frozen bananas, peanut butter, and protein powder that comes together in just 7 minutes. Perfect for busy mornings and picky eaters, this accidental recipe turned into a family favorite that tastes like soft-serve ice cream but is packed with protein and fiber.

Ingredients

Scale
  • 2 large ripe bananas, peeled, sliced, and frozen (about 2 cups frozen slices)
  • 2 tablespoons creamy peanut butter (natural preferred)
  • ½ cup milk (any kind; whole, almond, oat, or coconut)
  • 1 scoop vanilla protein powder (about 30g; whey or plant-based)
  • 1 tablespoon honey or maple syrup (optional, depending on sweetness preference)
  • 3–4 ice cubes (optional, for extra frosty texture)
  • For the toppings (choose your favorites):
  • ½ fresh banana, sliced
  • 2 tablespoons granola
  • 1 teaspoon chia seeds
  • 1 tablespoon dark chocolate chips
  • 1 tablespoon shredded coconut (toasted preferred)

Instructions

  1. Prepare your frozen bananas: If not already done, peel two ripe bananas, slice into coins, and freeze in a single layer on a baking sheet for at least 2 hours. Once frozen, transfer to a zip-top bag and keep in the freezer for up to 3 months. For this recipe, use 2 cups of frozen banana slices.
  2. Add the liquid first: Pour ½ cup of milk into your blender. This helps everything blend more smoothly.
  3. Add the peanut butter and protein powder: Spoon in 2 tablespoons of creamy peanut butter and add 1 scoop of vanilla protein powder. If using honey or maple syrup, add it now. Let the protein powder dissolve in the milk a little before adding frozen ingredients.
  4. Add the frozen bananas: Drop in 2 cups of frozen banana slices. If using ice cubes, add them now.
  5. Blend until smooth: Start the blender on low speed, then gradually increase to high. Blend for about 30 seconds, then stop and scrape down the sides with a spatula. Blend for another 20-30 seconds until thick and creamy with no visible chunks.
  6. Check the consistency: If too thick and the blender is struggling, add milk 1 tablespoon at a time and blend again. If too thin, add a few more frozen banana slices or an ice cube. The perfect consistency should be thick enough to hold its shape in a bowl but soft enough to eat with a spoon.
  7. Scoop into a bowl: Use a spatula to scrape every last bit into your favorite bowl. Smooth the top with the back of the spatula for an even surface.
  8. Add your toppings: Start with sliced fresh banana and a sprinkle of granola for crunch. Then add chia seeds, dark chocolate chips, and a drizzle of extra peanut butter if desired. Let kids pick their own toppings to make them more excited to eat it.
  9. Serve immediately: Smoothie bowls don’t sit well—they start to melt and lose their thick texture. Eat within 5-10 minutes of making.

Notes

For best results, use spotty ripe bananas for maximum sweetness and creamy texture. Start with less liquid and add more as needed—you can always thin it out but can’t thicken it back up. Don’t over-blend or the friction will warm the mixture and make it thin. If making for younger kids, blend an extra 10 seconds to ensure no peanut butter chunks remain. Leftovers can be poured into popsicle molds and frozen for a healthy treat, or spread on a parchment-lined baking sheet, frozen, and broken into pieces for smoothie bowl ‘cookies’.
