Cake Soup

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.

We put our slices of chocolate cake into bowls, poured milk on top and ate it with a spoon. That is cake soup.

Portillo’s Cake Shake

For those of you outside the midwest, Portillo’s is the BEST fast food in Chicago. They have the BEST Italian beef sammies, Chicago hot dogs, 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.

Ingredient Notes

Only three ingredients needed for chocolate cake shakes.

Just three easy ingredients in today’s chocolate milkshake recipe.

  1. Chocolate Cake- homemade chocolate cake is incredible, but really any leftover birthday cake will suffice. Stale? No problem. And make sure you grab a slice with lots of frosting!!
  2. Chocolate Ice Cream
  3. Milk– you’ll just need a splash, so use what you have in house!

How to Make a Chocolate Milkshake

Step by step photos showing how to make chocolate cake shakes in a blender.

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

You start with a big slice of chocolate cake and chocolate frosting in a blender. Add in some chocolate ice cream with a splash of milk. 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.

Don’t forget to garnish your cake with an extra slice of chocolate cake (haha) as well as some whipped cream!

What Chocolate Cake to Use

I like a plain, straight up slice of chocolate cake best for this recipe.

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 Dark Chocolate Cake.

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.

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 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. Cake soup… Ya know, I was devouring chocolate cake, in its many delectable varieties, in a bowl with milk in the ’50s, with mom.. We didn’t wait for it to be cooled, or frosted, and it RARELY got stale, or hard, we’d just whack out a chunk, into a bowl, grab that milk, and yummmmmm… Never knew there was a name for it…. But, oh, wow, have I had a craving lately.. Comfort food from the gods!!! Have a big bite for me!!

  2. We did that a lot in high school. Actually we put the pieces of cake in our glasses of milk because it was kind of dry. It was very good that way! People dunk cookies, why would cake soup be so weird?

  3. I love the Portillo’s Chocolate Cake Shake too! I know you can use any kind of chocolate (or other flavor as mentioned above) cake for this, but Portillo’s does use a chocolate mayonnaise cake. I had never heard of mayonnaise being in a chocolate cake before I had it there. So moist and yummy!

  4. Hi Amiee! Will you be my friend? This recipe is proof you will fit in perfectly with all my friends 🙂 We are a little confused about the leftover cake… it’s like leftover wine, we’ve never heard of it!

  5. This sounds so wonderful! I’ll be featuring it at the party tonight! Hope you stop by to check it out (starts at 8 http://willcookforsmiles.com/)

  6. I’m totally drooling over the cake garnish – the frosting looks so rich and glossy! Is it just buttercream, or something fancier?
    I feel like I need to go make a cake JUST to make a shake…

    1. Haha, I’m afraid to admit that was a canned frosting. Had to make it just for the shake!!! Fast and easy (and apparantly glossy too!)

  7. What an awesome post & recipe! We all do have our quirks huh? I love special traditions. You have SUCH a knack with making special desserts. Thanks soooo much for linking this up at Weekend Potluck. VERY special!

  8. I LOVE this picture! And the recipe 🙂 There was a place called Sammy’s in Provo, and they did pie and cupcake shakes. SO GOOD! You literally watched them scoop out the ice cream, shove your gigantic slice of pie in the shake cup, and then blend the mess outta that thing. It was so awesome. This takes me back 🙂

  9. I totally eat cake soup too!!!! I’m so glad to hear that I’m not the only one in this world who likes it. 🙂

  10. Thought that was something only my family did with day old cake. Nice to have a name for it, Cake soup!! Can’t wait to try the shake.

  11. Love the cake balancing on the side!! My family is certainly quickly. We don’t have cake soup, but I’d be willing to give it a try! I suspect my kids would think it’s the best thing ever!

  12. My nephew’s birthday was a couple days ago and I wanted the leftover chocolate cake to smoosh up & make into choc cake ice cream. I got some ‘looks’ as well. Seeing these tasty pics – I wish I had!

  13. I totally done this with my cake and sponge as a kid and would even wait until my ice cream had completely melted so I could mix it together. Maybe that’s why I love tres leches so much?
