There are far things better than the ol’ peanut butter/banana combo, and when they come together in this 4-ingredient smoothie, it’s definitely heaven in a glass.

Milk Substitutions in Smoothies

Soy milk, almond milk, and Coconut milk make great substitutions for regular milk when making smoothies.

Best Equipment For Making Smoothies

My first suggestion would be to use a NutriBullet.

This is the one that I have and it’s super powerful. It allows you to fully extract nutrients because it breaks down pulp, seeds, stalks, and skins so finely that you don’t even realize it’s there.

You can also use a good quality blender.

If you’re trying to cut back on added sugar, but you want to enjoy something sweet, this smoothie recipe is the perfect solution. It’s filling enough to make for breakfast, or you can share it for an easy snack. Using frozen banana is key to this recipe, as it gives the smoothie an ice cream-like texture. Paired with peanut butter and ground flax seeds, this smoothie packs extra protein and omega-3 fatty acids in each sip.

Ingredients You’ll Need

All you need is a few simple ingredients, including frozen bananas (yes, frozen is key!), peanut butter, and a little liquid to make this smoothie recipe come together. Be sure to freeze ripe bananas, with plenty of brown spots on their skin, to achieve a sweet flavor. Flaxseed adds filling fiber and helps the shake thicken up even more, but you can omit these if you don’t keep ground flax on hand. Chia seeds or rolled oats would also make an excellent add-in for thickening purposes. Feel free to use cashew butter, almond butter, or any other nut butter you have on hand. Add a scoop of protein powder or Greek yogurt for extra protein, or switch up the flavor by adding cocoa powder or a dash of cinnamon. You can customize a smoothie with any add-ins you like! Pro Tip: Be sure to remove the peel before freezing bananas. The peel is difficult to remove after freezing.

How to Make a Peanut Butter Banana Smoothie

Slice a frozen banana into small chunks for easier blending. Then add the banana pieces, peanut butter, ground flax seeds, vanilla extract, and almond milk to a high-speed blender.  Secure the lid and blend until very smooth, which takes about 60 seconds. You may need to use a tamper to keep everything blending smoothly. If you need to add an extra splash of water or milk, add just 1 tablespoon at a time, so the smoothie doesn’t become too runny in texture. For a thicker smoothie texture, add a handful of ice to the blended smoothie. Secure the lid and blend again, until the ice is pulverized, with no visible chunks remaining. Adding ice cubes will dilute the flavor slightly, so don’t add too much at once! You can always keep adding more if needed. This is a good option if you prefer to enjoy your smoothie with a spoon, rather than sipping it through a straw. Serve this creamy peanut butter banana smoothie right away, for the best flavor and texture. Pour it into a glass, or serve it as a smoothie bowl with your favorite toppings, like a handful of peanut butter granola, hemp seeds, or sliced banana. Any leftover smoothie can be poured into an ice pop mold and stored in the freezer if you want a frozen treat for later. Or, you can store it in the fridge for up to 48 hours, if you don’t mind a more runny texture later.
