How To Make Portillo’s Chocolate Cake
Now that you’ve gathered your ingredients, it’s time to bring this Portillo’s chocolate cake recipe to life! Follow these simple steps to create a cake that’s moist, rich, and utterly irresistible. Trust me, you’ll love the process and the results!

Step 1: Preheat the Oven and Prepare the Pans
- Preheat your oven to 350°F (175°C). This ensures your cake bakes evenly and turns out perfectly.
- Grease and flour two 9-inch round cake pans, or line them with parchment paper to prevent sticking. A light dusting of flour over the greased pans helps ensure the cakes come out smoothly once baked.
Step 2: Mix the Wet Ingredients
- In a large mixing bowl, add the water, vegetable oil, and eggs. Beat them together with a hand mixer or whisk until everything is well combined.
- Now, add in the mayonnaise and vanilla extract. Mix again until smooth. This creamy combination is the secret to achieving that ultra-moist, fudgy texture.
Step 3: Add the Cake Mix
- Gradually add the devil’s food cake mix to the wet ingredients. Stir the mixture until it’s just combined, being careful not to overmix. Overmixing can result in a denser texture, so mix until there are no dry spots, and the batter is smooth.
Step 4: Bake the Cake
- Divide the batter evenly between the prepared pans. Tap the pans gently on the counter to release any air bubbles and level the batter.
- Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. Keep an eye on the cakes—oven temperatures can vary slightly, so check at the 30-minute mark.
Step 5: Cool the Cakes
- Once baked, remove the cakes from the oven and let them cool in the pans for about 10 minutes. This allows the cakes to set and makes it easier to remove them.
- After 10 minutes, carefully turn the cakes out onto a wire rack to cool completely. Cooling is key for a flawless frosting application.
Step 6: Make the Frosting
- While your cakes are cooling, you can prepare the chocolate frosting. In a medium bowl, combine the butter, cocoa powder, and milk. Beat together until smooth and creamy.
- Gradually add the powdered sugar and vanilla extract. Continue mixing until the frosting is thick, spreadable, and fluffy. Adjust the consistency by adding a bit more milk if it’s too thick or a bit more powdered sugar if it’s too thin.
Step 7: Assemble and Frost
- Once the cakes are completely cool, place one layer on a serving plate or cake stand. Spread a generous layer of frosting on top.
- Add the second layer of cake and frost the top and sides with the remaining frosting. Smooth it out with a spatula for a professional finish.
Now that your cake is assembled and frosted, take a moment to admire your creation! This Portillo’s chocolate cake is everything you’ve dreamed of—moist, rich, and perfectly balanced. Get ready to serve a dessert that will wow anyone who tastes it!
Pro Tips and Variations for Portillo’s Chocolate Cake
Now that you’ve got your cake baked and ready to go, let’s elevate it with some expert tips and fun variations. Whether you’re looking to tweak the flavor or make the process even easier, these tips will guide you to perfection.
1. Pro Tips for a Perfect Chocolate Cake
- Use Room Temperature Ingredients
For a smoother batter and better texture, always use room temperature eggs and milk. Cold ingredients can cause the batter to seize up, resulting in a denser cake. - Sift the Dry Ingredients
Sifting your flour, cocoa powder, and baking powder helps eliminate clumps and ensures even distribution in the batter. This simple step leads to a smoother and more consistent cake. - Don’t Overmix the Batter
Mix until the ingredients are just combined. Overmixing can result in a tough cake, so keep the stirring gentle and brief. Remember, a light hand goes a long way! - Monitor the Baking Time
Oven temperatures can vary, so always check your cake at the 30-minute mark. Insert a toothpick or cake tester in the center—if it comes out clean or with a few moist crumbs, it’s ready to come out of the oven. - Cool Before Frosting
After baking, allow the cake layers to cool for at least 10 minutes in the pans, then transfer them to a wire rack. Frosting a hot cake can cause the frosting to melt and slide off, leaving you with a messy cake.
2. Flavor Variations and Fun Twists
- Add a Hint of Coffee
For a rich, deep chocolate flavor, try adding 1 teaspoon of instant coffee or espresso powder to the dry ingredients. It will amplify the chocolate taste without making the cake taste like coffee. - Go Nutty
For a little crunch and extra flavor, fold in chopped walnuts or pecans into the batter. Nuts pair wonderfully with the moist, rich chocolate cake for added texture. - Try a Layered Cake
Instead of making a two-layer cake, why not turn it into a decadent layer cake? Bake the batter in three 8-inch cake pans for a taller, more dramatic presentation. Just be sure to adjust the baking time slightly, as thinner layers cook faster. - Make It Gluten-Free
To make this recipe gluten-free, simply swap the all-purpose flour for a gluten-free flour blend. Ensure it contains xanthan gum to help with structure. Additionally, double-check the other ingredients to make sure they’re gluten-free, such as the baking powder. - Frosting Alternatives
While the classic chocolate frosting is always a winner, you can mix it up with different frosting types:- Cream cheese frosting for a tangy contrast.
- Whipped cream for a lighter, fluffier topping.
- Peanut butter frosting for a rich, nutty twist that complements the chocolate beautifully.
These tweaks will add personal flair to your cake while maintaining the delicious flavor that makes this Portillo’s-inspired chocolate cake so irresistible. Whether you stick with the classic recipe or explore these variations, you’ll be enjoying a show-stopping dessert in no time!
Serving Suggestions for Portillo’s Chocolate Cake
Now that you’ve baked and frosted your Portillo’s chocolate cake, it’s time to think about how to serve it. After all, a beautiful cake deserves an equally beautiful presentation. Whether you’re hosting a party or simply indulging in a slice for yourself, here are some creative serving ideas to elevate your cake and make it even more special.

1. Classic Cake Stand Presentation
For an elegant touch, display your cake on a cake stand or platter. This simple gesture immediately makes the cake feel like the star of the show. Garnish the top with a few chocolate shavings, sprinkles, or even a light dusting of powdered sugar. It’s a perfect, classic look for any occasion!
2. Serve with a Side of Fresh Berries
Pair your Portillo’s chocolate cake with a handful of fresh berries, like raspberries or strawberries. The tartness of the berries beautifully balances the richness of the cake and adds a pop of color to your presentation. You can even drizzle a bit of chocolate syrup over the berries for an extra indulgence.
3. A Scoop of Ice Cream
Nothing beats the combination of cake and ice cream. Serve your slice with a scoop of vanilla, chocolate, or even coffee ice cream for an extra creamy, indulgent treat. The contrast between the warm cake and cold ice cream is heavenly.
4. Whipped Cream or Ganache
Top your cake with a generous swirl of freshly whipped cream, or drizzle it with chocolate ganache. The creaminess of the whipped topping enhances the cake’s moist texture, while the ganache adds an extra layer of decadence. For a fun twist, try peanut butter whipped cream for a nutty contrast to the chocolate.
5. Mini Cake Bites for a Party
If you’re serving this cake at a party or gathering, consider cutting it into small, bite-sized pieces. These mini pieces are perfect for guests to grab as they mingle, and they look charming on a platter. You can even serve them with toothpicks or small forks for easy eating!
6. Coffee or Milk Pairing
For a cozy touch, serve your Portillo’s chocolate cake with a hot cup of coffee or a cold glass of milk. The coffee’s rich bitterness pairs beautifully with the sweet chocolate, while milk offers a classic, creamy complement. Either way, you’ve got the perfect pairing to balance out the dessert’s sweetness.
7. Layer it with More Flavor
Want to amp up the flavor? Add a layer of caramel sauce or a sprinkle of toasted coconut on top of the frosting. These additions give the cake an exciting twist and make it even more irresistible.

FAQs
Got questions? No worries! Here are some common questions about making and enjoying Portillo’s chocolate cake, along with useful tips to help make your baking experience a success.
1. Can I make this cake ahead of time?
Absolutely! In fact, this cake gets even better after it has had a chance to sit for a day or two, as the flavors have more time to meld together. You can make the cake 1-2 days in advance and store it in an airtight container at room temperature. If you need to frost it later, just make sure the cake has cooled completely before adding the frosting.
2. How can I store leftovers?
To keep your Portillo’s chocolate cake fresh, store any leftovers in an airtight container. It will stay delicious for up to 4-5 days at room temperature. If you want to extend its freshness, you can refrigerate it for up to 1 week, but let it come to room temperature before serving for the best texture.
3. Can I freeze this cake?
Yes, this cake freezes wonderfully! If you have any leftover cake or want to make it in advance for a future event, just wrap the cake tightly in plastic wrap and aluminum foil before freezing. It will stay fresh in the freezer for up to 3 months. To thaw, place it in the fridge overnight, and frost when ready to serve.
4. Can I use a different frosting?
Definitely!While the chocolate frosting is classic, you can experiment with other frosting options to suit your taste. Some great alternatives include:
Cream cheese frosting for a tangy contrast to the rich cake.
Peanut butter frosting for a nutty, indulgent twist.
Whipped cream for a lighter, airy topping.
5. How can I make the cake less sweet?
If you prefer a less sweet cake, you can reduce the sugar in both the cake and frosting. For the frosting, you can also use a more bittersweet chocolate to balance the sweetness of the cake. Additionally, swapping out half of the sugar for a sugar substitute, like Stevia or Erythritol, can help reduce the overall sweetness
6. Can I make this cake without eggs?
Yes, you can! If you’re looking for an egg-free version, simply substitute flax eggs (1 tablespoon of ground flaxseed mixed with 3 tablespoons of water per egg) or applesauce (1/4 cup per egg) in the recipe. Both options will maintain the moisture and texture of the cake.
7. What if I don’t have mayonnaise?
Mayonnaise is a key ingredient in this recipe because it adds richness and moisture. If you don’t have any on hand, you can use sour cream or Greek yogurt as a substitute. Both will provide the same creamy texture and help keep the cake moist.
8. Can I use gluten-free flour for this recipe?
Yes! To make this cake gluten-free, simply replace the all-purpose flour with a gluten-free flour blend. Be sure to check that the blend includes xanthan gum, as this helps give the cake structure.
