I still remember the first time I tasted Portillo’s Chocolate Cake. It was my birthday, and a friend showed up with a whole cake instead of a traditional gift. “Trust me,” she said, “this is better than anything wrapped in a box.” Skeptical but intrigued, I took a bite. Instantly, I was hooked. It was everything a chocolate lover dreams of—rich, impossibly moist, and slathered in the silkiest chocolate frosting. Since that day, Portillo’s Chocolate Cake has been my go-to indulgence, and if you haven’t tried it yet, you’re in for something special.

Let’s talk about why Portillo’s Chocolate Cake is so legendary, why it has a cult following, and most importantly, how you can make it at home. Because let’s be real—once you’ve had it, you’ll want it all the time.

The Legend of Portillo’s Chocolate Cake

If you’ve ever been to Chicago or know someone who has, chances are you’ve heard about Portillo’s. Known for their hot dogs, Italian beef sandwiches, and crinkle-cut fries, this restaurant has another claim to fame—Portillo’s Chocolate Cake. And it’s not just “good for a fast-food place.” It’s hands-down one of the best chocolate cakes out there, rivaling high-end bakeries and homemade favorites.

What makes it so irresistible? Picture two thick layers of soft, fluffy chocolate cake with just the right amount of sweetness. The frosting? It’s rich, smooth, and perfectly balanced—neither too heavy nor too sugary. But the real secret? It’s been rumored that mayonnaise is the key ingredient! Yes, you read that right. It might sound strange, but it’s what makes the cake incredibly moist and tender.

What’s even more fascinating is how this cake became a staple at Portillo’s. Unlike traditional bakeries that focus solely on desserts, Portillo’s is primarily known for its savory menu. Yet, this chocolate cake has managed to shine just as brightly as their signature hot dogs and Italian beef. It’s the kind of dessert that turns first-time customers into lifelong fans. From birthdays to anniversaries to simple cheat-day indulgences, Portillo’s Chocolate Cake has become a go-to treat for any occasion.

How to Make Portillo’s Chocolate Cake at Home

If you can’t make a trip to Portillo’s, don’t worry—you can still enjoy their famous cake from your own kitchen. After experimenting with different recipes, I’ve found one that comes pretty close to the real thing. And yes, it includes mayonnaise!

Ingredients:

• 1 box of devil’s food cake mix
• 1 cup of water
• 3 eggs
• 1 cup of mayonnaise (trust me on this!)
• 1 tub of chocolate frosting (or make your own!)

Instructions:

1. Preheat your oven to 350°F (175°C). Grease and flour two 9-inch cake pans.
2. In a large mixing bowl, combine the cake mix, water, eggs, and mayonnaise. Beat until smooth.
3. Divide the batter evenly between the two cake pans and bake for about 30 minutes, or until a toothpick inserted into the center comes out clean.
4. Let the cakes cool completely before frosting. (Patience is key! Frost too soon, and you’ll end up with a melty mess.)
5. Frost generously between the layers and over the top. More frosting = more happiness.
6. Slice, serve, and enjoy!

Pro tip: Warm a slice in the microwave for 10 seconds for an even more indulgent experience.
