Ingredients You’ll Need
Make sure to scroll to the recipe card at the bottom of the post for the full recipe and ingredient list!
- Vanilla Ice Cream. This is the base of the shake. Use a good-quality vanilla ice cream for the best flavor.
- Whole Milk. Milk helps blend everything together while keeping the milkshake thick and creamy. You can sub it out for any other milk option you prefer, but whole milk will give you the creamiest milkshake texture.
- Dry Cake Mix. This is the secret ingredient that gives the milkshake its birthday cake flavor.
- Tip: Use vanilla, white, yellow, or Funfetti cake mix. Even chocolate could be great!
- Rainbow Sprinkles. Because it isn’t a birthday cake milkshake without sprinkles!
- Vanilla Frosting. This is used to decorate the glass and help the sprinkles stick. Funfetti frosting would be super fun too!
- Optional Toppings:
- Whipped cream
- Extra sprinkles
- Cake cubes
- Birthday candles
- Maraschino cherries
But Is It Safe To Eat Dry Cake Mix?
Many readers ask this because cake mix contains raw flour. If you’d like to be extra cautious, heat-treat the cake mix before using it. Simply spread it on a baking sheet and bake briefly before cooling completely. You can even microwave it to kill any germs of desired. Do this in 30 second increments, stirring after each until the temperature reaches 165°F.
How to Make a Birthday Cake Milkshake
Step 1: Decorate the Glass
Spread frosting around the inside rim of your serving glass. Roll the rim in rainbow sprinkles and place the glass in the freezer while you prepare the shake.

Step 2: Blend the Milkshake
Add the following to a blender and blend until smooth and creamy.
- Vanilla ice cream
- Whole milk
- Dry cake mix
- Sprinkles

Step 3: Serve
Pour the milkshake into the prepared glass, garnish and enjoy immediately. Here are some topping ideas:
- Whipped cream
- Extra sprinkles
- Cake cubes
- A birthday candle if you’re feeling festive
Tips for the Best Birthday Cake Milkshake
- Use Full-Fat Ice Cream. The richer the ice cream, the creamier the milkshake.
- Start With Less Milk. You can always add more milk if needed, but you can’t make it thicker once it’s blended.
- Freeze the Glass. A chilled glass keeps your milkshake cold longer and makes it feel extra special.
- Add More Cake Flavor. For an even stronger cake batter flavor, add an extra tablespoon of cake mix.
Fun Variations
- Chocolate Birthday Cake Milkshake. Use chocolate cake mix and chocolate ice cream. Even chocolate milk instead of white whole milk amp up the chocolate flavor! Garnish with chocolate sprinkles!
- Strawberry Birthday Shake. Blend in a handful of fresh strawberries. Use strawberry frosting, and even a sweet drizzle of strawberry syrup!
- Birthday Cake Protein Shake. Add a scoop of vanilla protein powder and reduce the cake mix slightly.
