Freezing bananas for smoothies 

It is super easy to freeze overripe bananas! Other than using it in smoothies, they can also be used in baked goods like bread and cookies. Here are the steps to freeze bananas – 

1. Slice bananas into ¼ – ½ inch coins. 
2. Arrange them in one layer on a baking sheet lined with parchment paper. Pop it into the freezer until they have hardened. 
3. Transfer frozen bananas into a zip-top bag, and they can be frozen for up to 3 months! 
4. Before making your smoothie, let frozen bananas thaw and soften for 5-10 minutes at room temperature. 

What you will need 

Ingredient notes and substitutions 

• Peanut butter powder – Essentially grounded peanuts stripped from most of their oil. You can find it in most well-stocked groceries or on Amazon. I am using and loving the PB2 powdered peanut butter. 
• Protein powder – An optional ingredient. However, I highly recommend adding it to significantly bump up the protein content of this peanut butter powder smoothie! You can use a vanilla or peanut butter flavored one. 
• Milk – Any regular or plant-based milk will work in this recipe. You can also use water, but your smoothie will be less creamy. 

How to make 

Place all ingredients in a blender. Blend until smooth, adding more milk if needed. Your powdered peanut butter smoothie is ready to be enjoyed! 

Helpful tips 

• You can substitute the peanut butter powder with 2-3 tablespoons of smooth peanut butter. 
• I recommend investing in a high speed blender, like Vitamix, if you make smoothies often. It saves tons of time and effort! 
• Err on the side of less liquid, to begin with. You can always add more later if needed. 
• If you like a sweeter smoothie, add 2-3 teaspoons of maple syrup or honey. Alternatively, mix in a deseeded date. 
• Begin blending at a lower speed, then slowly increase the speed as the ingredients start coming together. 

Variations and add-ins 

Chocolate peanut butter – You can use a chocolate-flavored peanut butter powder or protein powder. Add a few teaspoons of cocoa powder to make your smoothie extra chocolatey. 

No banana version – Replace banana with 2-3 deseeded dates, and add 1-2 more tablespoons of oats to thicken your smoothie. Alternatively, you can substitute it with 1 cup of frozen berries. 

Smoothie bowl – Reduce the amount of liquid or add more banana to thicken. Top it with toppings like protein granola, peanut butter, chocolate chips, or fruits like sliced bananas or berries. 

Seeds – For healthy fats, blend 1-2 tablespoons of chia, hemp, or flax seeds to your smoothie. 

Veggies – Frozen kale, spinach, cauliflower, or zucchini are some veg that works amazingly in smoothies. 

Storing suggestions 

Fridge – Peanut Butter Powder Smoothie can be refrigerated for 1-2 days. It is normal for the smoothie to turn brownish after a couple of hours as the banana oxidizes. 

Freezer – You can freeze them in freezable jars or ice-cube trays for up to 3 months. Let them thaw overnight in the fridge or at room temperature for a couple of hours before enjoying them. 

If short on time, throw in a few smoothie cubes along with a splash of water or milk in a blender and blend until smooth.
