Smoothie Ingredients

Here’s a breakdown of the ingredients you’ll need to make this Tropical Smoothie chocolate peanut butter cup recipe:

  1. Cocoa powder is what gives this smoothie its rich, chocolatey flavor. It’s also rich in antioxidants, fiber, and minerals such as iron and magnesium.
  2. Creamy peanut butter is a staple ingredient in tons of smoothie recipes, and for good reason. It’s rich in protein and healthy fats to help keep you feeling full and satisfied. If you need a PB swap, feel free to use any other nut butters like almond or cashew butter.
  3. Frozen banana is the secret to creating the thick and creamy texture of this smoothie. Bananas are also a great source of fiber, vitamins, and minerals. Use ripe bananas that have been peeled, sliced, and frozen for at least 2 hours prior to making the smoothie (or use store-bought).
  4. Milk also helps to make that perfect creamy consistency. You can use any type of milk you prefer, whether it’s dairy milk or dairy-free options like almond milk, soy milk, or oat milk. If you’re lactose intolerant or vegan, plant-based milk is a great option.
  5. Maple syrup brings out the rich, chocolatey flavor in this smoothie and adds just the right amount of sweetness.
  6. Ice: Adding ice to your smoothie is optional, but it’s a great way to create a thicker, creamier texture and give your smoothie a milkshake-like consistency. If you prefer an even creamier smoothie, you can skip the ice and use frozen milk cubes instead.

Make It A Balanced Meal Smoothie

As is, this peanut butter cup smoothie recipe works great as a filling and delicious snack or mini meal, but it’s probably not enough for a full meal. If you want to swap this smoothie in for breakfast, here’s what you can do:

  • Add a protein: My fave protein sources to add to this smoothie would be a 5 ounce container of Greek yogurt or cottage cheese, a serving of your favorite protein powder (whey protein or plant-based works!), or have some protein on the side (for example: a couple of hard boiled eggs).
  • Optional- add a veggie! Yes, you heard me right! If you want to add a little more volume and more fiber, you can throw in a handful of spinach or frozen cauliflower.

Variations and Recipe Tips

  • Add more or less liquid to reach your desired consistency. If you’re having trouble getting it to be the thickness that you want, add some ice and blend well!
  • Add more fruit like strawberries or blueberries.
  • Use any nut butter that you like: almond butter, sunflower seed butter, cashew butter, or hazelnut butter all work great.
  • Add a boost of fiber and healthy fats with flax seeds or chia seeds.
  • Make it a smoothie bowl by cutting the liquid in half and adding Greek yogurt. You can top with shaved chocolate, your favorite nuts and seeds, granola, and fresh fruit.
  • Top with melted peanut butter, whipped cream and mini chocolate chips for major milkshake vibes!

    So good! Love that it’s not too sweet. I think I’ll add Greek yogurt next time for a bit more protein, too! 🙂

    How have I not made this simple of a smoothie before! I added a 1/2 cup of cottage cheese and subbed some of the milk with water since I added that. So delicious!
