Strawberry Peanut Butter Smoothie Recipe for Creamy Protein Boost

This creamy, delicious Strawberry Peanut Butter Smoothie is an easy snack or breakfast you can make in about 5 minutes. It’s protein-packed and full of real strawberry and peanut butter flavor — basically a PB&J in smoothie form.

Smoothies don’t always need to be green — sometimes a fruity, indulgent blend is exactly what you want. This Strawberry Peanut Butter Smoothie is a family favorite at our house. It’s simple, satisfying, and easy to customize.

While I often make smoothies packed with nutritious ingredients, I also love fun, dessert-like blends. If you enjoy this one, try swapping ingredients or pairing with other recipes for variety. A thick frozen-fruit base and a scoop of peanut butter make this feel like a milkshake while still delivering real nutrients.

Why you will love this Strawberry Peanut Butter Smoothie

• Kid friendly. The ingredients are familiar and kid-approved, so little helpers usually love it. (Our toddler even begs for spinach sometimes, so feel free to sneak greens in.)
• Simple pantry ingredients. You likely have everything on hand: frozen fruit, banana, milk, peanut butter, and optional protein powder.
• Filling and balanced. Peanut butter plus optional protein powder add staying power, making this a satisfying snack or light breakfast.

Ingredients and Substitutions

See the recipe card below for exact measurements. Key ingredient notes and easy swaps are listed here.

• Strawberries: Use frozen strawberries for a colder, thicker smoothie. Fresh berries work too — you can freeze them ahead of time if you prefer.
• Frozen banana: Frozen banana creates a creamy texture and natural sweetness. This is one ingredient I recommend keeping frozen rather than substituting.
• Milk: Unsweetened vanilla almond milk is a favorite for flavor and lower calories, but whole milk, oat milk, or any preferred dairy-free milk work well.
• Protein powder: Optional, but useful if you want extra protein. Vanilla works best here, though chocolate could be tasty if you prefer.
• Optional sweetener: If your strawberries are tart, add a touch of honey or maple syrup to taste. The banana adds natural sweetness for many people.

Recipe Variations

• Add a handful of spinach or baby kale for extra nutrients — the flavor is mild when combined with banana and peanut butter.
• Stir in a scoop of Greek yogurt for more protein and creaminess.
• Substitute or add other berries like raspberries or blueberries for a mixed-berry version.
• Swap nut butters: almond, cashew, or sunflower seed butter all work if you need a peanut-free option.
• Boost fiber and omega-3s with a tablespoon of chia or ground flax seeds.

How to make this smoothie

Place the ingredients in a high-speed blender and blend until smooth. For best blending, pour the milk in first, then add the rest of the ingredients. Start with the lower amount of milk and add more if the smoothie is too thick. Taste and sweeten as needed.

Serve immediately for the best texture and flavor. Enjoy!

Notes and Tips:

• Use a tamper if your blender has one to help process thick blends evenly without making the mixture soupy.
• Choose a protein powder you like. A poor-tasting powder can affect the whole smoothie; unflavored collagen works well if you prefer a neutral option.
• Customize freely. Add chia, flax, cinnamon, hemp seeds, or other mix-ins to boost nutrition and flavor.
• To make a smoothie bowl, start with less milk (about 1 cup) and adjust to reach a thicker consistency suitable for toppings.
