  1. Healthy yet indulgent: One of the biggest reasons you'll love this recipe is that it's a healthy twist on a classic treat. By using wholesome ingredients like protein powder, milk, and Greek yogurt, you can enjoy the satisfying taste of a milkshake with the benefit of increasing your protein intake! Plus, with the addition of rainbow sprinkles, you'll get a fun and festive appearance that's perfect for a birthday or everyday celebration.
  2. Easy to make: This recipe is so incredibly easy to make. With just a few simple ingredients and a blender, you can whip up a creamy and delicious milkshake in no time. Plus, you can customize the recipe to your liking by adjusting the amount of sweetener or using different types of milk or yogurt.
  3. It's packed with protein: This milkshake is also packed with protein, making it the perfect post-workout snack or when you find you’re slacking on your protein intake. With the addition of vanilla protein powder and Greek yogurt, you'll get a boost of protein that will help you feel full and satisfied.


  • Frozen cauliflower: This is my #1 hack to achieve a creamy milkshake without it being icy! I used Green Giant frozen cauliflower florets. It has no taste, PLUS it adds a veggie serving to your day! If you prefer not to use it, simply use ice in place of the cauliflower. 
  • Vanilla ice cream: I used Edy’s Slow Churn ice cream in vanilla bean flavor to add to the creamy flavor. I love this line because it has ½ the fat of regular ice cream and tastes delicious! 
  • Protein powder: I used PEScience Cake Pop protein powder but also love Clean Simple Eats Cake Batter (code TAMI saves you). You may use your favorite protein powder in vanilla! 
  • Milk: I used almond milk to keep this recipe lighter on calories. You may use regular milk if you prefer or your favorite milk alternative like oat milk, cashew milk, etc. 
  • Cake batter extract: This is to increase the overall cake flavor. You may omit if you prefer a lighter cake flavor. 
  • Rainbow sprinkles: It wouldn’t be a birthday cake without a burst of color!

Swaps or Alternatives

While the recipe for the birthday cake protein milkshake is already a healthy alternative to traditional milkshakes, there are still some ingredient swaps or alternatives you can make to fit your dietary needs and preferences. Here are a few ideas:

  1. Milk alternatives: If you're lactose intolerant or following a dairy-free diet, you can swap the unsweetened almond milk for another plant-based milk like coconut milk, soy milk, or oat milk.
  2. Ice cream alternatives: If you're vegan, you can use non-dairy ice cream instead. 
  3. Cauliflower alternatives: If you don't want to use cauliflower, you can try using frozen bananas instead. This will give your shake a banana flavor. You can also just use ice instead!
  4. Protein powder alternatives: If you don't have vanilla protein powder on hand, you can use a different flavor like chocolate or strawberry. You can also use plant-based protein powder if you're vegan. Use a different flavor of protein powder will alter the taste of your milkshake!
  5. Sprinkle alternatives: If you don't have rainbow sprinkles or prefer not to use them, you can leave them out or add a few chocolate chips, crushed Oreos, or chopped nuts for some texture and flavor.

Quick Tip(s)

A quick tip for making the birthday cake protein milkshake recipe is to add the rainbow sprinkles at the very end and pulse the blender a few times until they're just mixed in. This will help the sprinkles maintain their shape and texture, giving the milkshake a fun and festive appearance without becoming soggy or overly blended.


What are the benefits of drinking a protein milkshake?

This recipe is a great way to get the protein you need for a healthy diet. Protein helps build and repair muscles, boosts energy levels, and helps you feel full longer. Additionally, it's a healthier alternative to traditional milkshakes, which are often high in calories and sugar.

Is a birthday cake protein milkshake suitable for vegans?

Yes! You can make a vegan version of a birthday cake protein milkshake by using a plant-based protein powder and non-dairy milk such as almond or coconut milk.

Can I customize this recipe to my taste?

Absolutely! You can customize the ingredients in a birthday cake protein milkshake to suit your tastes and dietary preferences. For example, you can use different types of protein powder, add fruits such as bananas or strawberries, or switch up the type of milk you use.

When is the best time to drink a birthday cake protein milkshake?

You can enjoy this recipe at any time of day, but it's a great choice for a post-workout snack or a mid-day pick-me-up. It's also a fun treat to enjoy for dessert if you find you need to get more protein in at the end of the day!
