Every family has its quirks. Sometimes you don’t realize what your family’s quirks are until you grow up and find out that no one else was eating “cake soup” on their birthdays. 
I grew up thinking “cake soup” was normal. 
Birthdays were an awesome time, not because of the presents, but because of the plain chocolate cakes with white frosting. We didn’t eat them on plates with ice cream. Instead, we put our slices of chocolate cake into bowls, poured milk on top and ate it with a spoon. 
Yes, cake soup.
There were a few cousins and others in the family who thought it was odd, but for the most part, this is just what my family did.
Then I went out in the real world. And in the real world, apparently people are appalled by the idea of eating your cake this way. I would TRY so hard to make people understand, and taste my “cake soup.” 
Most of the time I just got weird looks.
Then, one glorious day last year, my brother told me about Cake Shakes.

Portillo’s Cake Shakes

For those of you outside the midwest, Portillo’s is the BEST fast food in Chicago. They have the BEST Italian beef sammies, french fries and chocolate cake.

Guess what they did with that chocolate cake?
Yep, they blended it right into a chocolate shake.
Want to know what it tastes like?

Finally, I feel like people get me. When they give me strange stares, all I have to say is, “It tastes like a Portillo’s cake shake.”
Next time you make a cake, instead of throwing away the leftovers (the horror!) stick a few slices of cake in the freezer for making Chocolate Cake Shakes. 

Chocolate Cake Shake Recipe

Making Cake Shakes are no more difficult than making a typical chocolate milkshake.

You start with chocolate ice cream, added to the blender with a splash of milk. Toss in a big slice of chocolate cake covered in chocolate frosting, then blend until smooth.

If you want it thinner, add a little more milk. For a thicker shake you can eat with a spoon, start with the teeniest splash of milk and go from there.

What Chocolate Cake to Use

I like a plain, straight up slice of chocolate cake best for this recipe. Don’t forget the chocolate frosting!

Leftover Wacky Cake with a layer of The Best Chocolate Buttercream Frosting works beautifully here. Those recipes are easy enough to whip up without much notice if a sudden Chocolate Cake Shake craving strikes. I’ve also made my copycat Portillo’s Cake Shake with  leftover pieces of my go-to Perfect Chocolate Cake .

Chocolate Frosted Chocolate Cupcakes work well here too! The amount of cake in this chocolate milkshake should be equal to approximately 2 cups. That’s one giant slice of regular cake or about 2 normal sized cupcake’s worth.

Substitutes and Variations

Me? I love chocolate cake shakes the very best. But all kinds of cake and ice cream combos work here. Live your best cake shake life with whatever flavors you choose! Try these ideas:

  • Birthday Cake Shake – Vanilla ice cream and white or yellow frosted birthday cake. Top with whipped cream and sprinkles!
  • Strawberry Cake Shake – Strawberry ice cream and cake. Chocolate cake will make the shake taste like chocolate covered strawberries!
  • Black and White – Vanilla ice cream and chocolate cake for those who love both!

I’m so excited that cake soup is socially acceptable now. . . at least when you blend it up and call it a Cake Shake instead! I hope you enjoy it too.

Comments & Reviews

  1. People always think I’m crazy because I love to take a bowl of cake & ice cream and immediately smash all of it together until it’s just cake ice cream. Sooooooo good!

  2. Growing up we put our cake right in a glass of milk. I preferred a tall glass of Nestle’s Quik with my cake. I still eat it today as a special treat. Mom said, “this was how we ate stale cake and crackers during the depression.”
