My kids love visiting the local Soda Jerk Milkshake Bar and similar places in Scottsdale. Their over-the-top milkshakes are fun and delicious, but at $14+ each, they’re a bit pricey as a “just because” treat.

But that doesn’t mean we can’t still enjoy them!

Today, I wanted to share an easy base shake recipe that recreates Aubrey and Owen’s favorite flavors of fun milkshakes, but in a way that anyone can make quickly!

Ingredients Needed for the Best Birthday Cake Shake

  • Vanilla Ice Cream: The creamy base for your milkshake. You can even use cake batter ice cream for extra flavor.
  • Whole Milk: Helps thin the ice cream to a perfect shake consistency.
  • Vanilla Frosting: Adds that classic birthday cake flavor and a smooth, sweet finish.
  • Vanilla Cake Slices: Adds texture and indulgence, just like the shakes at the milkshake bars.
  • Whipped Cream: A must for topping your milkshake. Use your favorite canned whipped cream!
  • Colorful Sprinkles: Adds a festive flair to the rim and the top. Adjust colors based on your theme/season. For this recipe, we stuck to the classics.
  • Maraschino Cherries: A classic finishing touch for milkshakes.

How to Make a Birthday Cake Milkshake

  • Start by frosting the rim of your tall glass with vanilla frosting, then gently roll the edge in rainbow sprinkles. Set aside while you prepare the milkshake.
  • In a blender, combine vanilla ice cream, whole milk, and vanilla frosting. Blend for at least 30 seconds until smooth and creamy. If your blender is less powerful, you may need to soften the ice cream slightly or use it for a little longer.
  • Pour the milkshake into the prepared glass and top with a slice of vanilla cake. Then, pile on whipped cream (canned or homemade) and finish with a cherry. Serve immediately with a thick straw or spoon.
  • You can easily double your ingredients to make 3-4 milkshakes!

Can’t Find a Mini Cake? Use Cupcakes!

If your grocery store or Walmart doesn’t have the small $5 cake, no worries. You can easily swap in one or two frosted cupcakes. You can either use a whole cupcake per shake or cut one in half and place it on top of the whipped cream instead. You’ll get the same fun look and flavor without needing to buy a whole cake.

Tips for Getting the Cake to Stay on Top

Wondering how to balance the cake on your milkshake? Try laying a clean popsicle stick or wooden skewer across the glass and resting the cake on top. It’s a super easy hack that works especially well with taller slices or larger cupcakes.

Want to Make It Chocolate Instead?

To turn this into a chocolate cake shake, simply substitute chocolate ice cream for vanilla, use chocolate frosting, and top with chocolate cake. Drizzle with chocolate sauce or hot fudge for a decadent twist on the original.
