This peanut butter cup smoothie recipe is chocolatey and smooth, and will keep you satiated because it is high in fat, protein and fiber. As a bonus, it has no added sugar and is a great way to get some energy back after working out!

Lets be real, smoothies are an easy recipe. Probably one of the easiest because you’re just adding ingredients to a blender, but they’re also versatile and it’s fun to find new flavor combinations.

It can be consumed as a delicious healthy breakfast, midday meal, filling snack or even dessert. Below I provide options for ingredient substitutions and recipe variations.

Recipe ingredient substitutions

Cocoa substitutions: Instead of using cocoa, you can use raw cacao which is a less processed form of the cacao bean. If you can’t do chocolate, you can swap it out for carob powder.

Peanut butter substitutions: Instead of peanut butter, you can also use sunflower seed butter, almond butter, cashew butter etc. Get your healthy fats in! If you want to keep it as clean as possible, go for a natural peanut butter with no added ingredients.

Collagen powder substitutions: Instead of using collagen powder, you can use other simple ingredients like vegan vanilla protein powder or just omit altogether. Getting those grams of protein in is one of the best things about smoothies.

Oat milk substitutions: Instead of oat milk, you can use soy milk, coconut milk, cashew milk, rice milk, etc. Try to pick one that doesn’t have any added sugar – like unsweetened almond milk. I think most of the non-dairy milk in the grocery store is unsweetened these days.

Fresh banana substitutions: You can also use frozen banana chunks, or even those overripe bananas you need to use up. Instead of banana, you could also use avocado as a replacement. Without the natural sweetness of the banana though, you might want to add a little maple syrup or honey.

Vanilla extract substitutions: Instead of liquid vanilla extract, you can use vanilla bean paste, or vanilla bean powder.

Dietary modifications

Make this recipe vegan: Omit the collagen powder. Optionally, swap it out for vegan protein powder or just omit altogether. Bingo, vegan smoothie!

Make this recipe lower calorie/fat: Reduce the amount of peanut butter to 1 tablespoon. Swap out the oat milk for a lower calorie dairy free milk such as unsweetened almond or cashew milk. You can also use peanut butter powder which is sold at most grocery stores and is lower in fat.

Make this recipe lower oxalate: Instead of using oat milk, swap it out for coconut milk. Swap out the peanut butter for sunflower seed butter and reduce the amount of cocoa powder to ½ tablespoon (or omit).

Make this recipe lower sugar/carb: Instead of using oat milk, use a lower carb milk such as unsweetened almond milk or cashew milk. Reduce the amount of banana to one half.

Make this recipe sweeter: If you are having this smoothie as a dessert, add 1 tablespoon of maple syrup or honey to make it a bit sweeter.

Recipe variations

Add probiotics: Add a cup of plain greek yogurt instead of milk. If you don’t do dairy, there are a lot of vegan yogurt options these days too!

Include some delicious add-ins: For an extra boost, add protein powder, hemp seeds, or MCT oil. You could even include some frozen berries, fresh strawberries or any other fruit.

Make this into a smoothie bowl: Make this into a smoothie bowl by adding banana slices, chia seeds, hemp seeds, whole peanuts, chocolate chips, and shredded coconut. The smoothie is just a base for whatever toppings you want.

Make it a dessert smoothie: Pump up the calories by swapping the milk for ice cream. Who cares about calories or daily values! Plus a creamy texture and thick consistency is what we all want anyway!

Pro tips for this recipe

Make this smoothie colder: Freeze the banana ahead of time, and make sure your dairy free milk is straight out of the fridge. Optionally, you can also freeze some of your dairy-free milk in an ice cube tray. Adding Ice cubes makes for a thicker smoothie!

Drink this smoothie as soon as possible after making it: Smoothies don’t tend to do well in the fridge over time, and often ingredients will start separating and the texture will change. Try to drink this smoothie as soon after you make it as possible.

What to do if your smoothie is too thick or isn’t blending: Depending on whether you use a food processor or blender, you may find you don’t have enough liquids. If this is the case, add an additional ½ cup of oat milk or other dairy free milk. If you used vegan protein powder instead of collagen powder, it will soak up a lot more liquid, so in this case you might need to add additional liquid.

Storage tips

This smoothie recipe makes the perfect portion size, but if you have some left over you can store it in the fridge in a sealed Mason jar for a day or so. It really is best served fresh though. The ingredients may start separating if it sits for too long.

You could make this smoothie in the morning though and bring it to work in a sealed Mason jar. Shake it up before consuming.
