Step-by-Step Instructions
Step 1: Prepare Your Workspace
Preheat your oven to 350°F (175°C) and grease two 9-inch round cake pans. Line the bottoms with parchment paper for foolproof removal. This simple 2-minute step prevents 90% of cake disasters!
Step 2: Combine Dry Ingredients
In a large bowl, whisk together the flour, sugar, baking soda, and salt. The uniform distribution of these ingredients will create that signature even texture Portillo’s cakes are known for.
Step 3: Create the Chocolate Base
In a medium saucepan, combine butter, water, and cocoa powder. Heat over medium heat until the butter melts completely, stirring occasionally. This melting method releases cocoa’s aromatic compounds more effectively than cold mixing.
Step 4: Blend the Cake Mix
Add the chocolate cake mix to your dry ingredients and mix until combined. This is Portillo’s secret—they use a combination of scratch ingredients and quality cake mix for that distinctive texture!
Step 5: Combine Wet and Dry Ingredients
Pour the chocolate mixture into the dry ingredients and beat until well combined. Add eggs one at a time, then buttermilk and vanilla, mixing between each addition. Your batter should look glossy and smooth.
Step 6: Bake to Perfection
Divide batter between the prepared pans and bake for 30-35 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. Cool in pans for 10 minutes before transferring to a wire rack.
Step 7: Prepare the Frosting
While the cake cools, melt butter in a saucepan, add milk and cocoa powder, and bring to a boil for 30 seconds. Remove from heat, add vanilla and salt, then gradually whisk in powdered sugar until smooth and glossy.
Step 8: Frost Your Creation
When the cake has completely cooled, spread a layer of frosting between the layers, then cover the top and sides. Work quickly as this frosting sets faster than traditional buttercream—just like at Portillo’s!

FAQs
Can I make this cake without the boxed mix component?
While you can create a fully from-scratch version, the boxed mix contributes to Portillo’s signature texture. For a 100% scratch version, add an additional 1½ cups flour, ¾ cup sugar, 1 teaspoon baking powder, and 2 tablespoons cornstarch.
How far in advance can I make this cake?
You can prepare the cake layers up to 3 days ahead and store them wrapped in plastic at room temperature, or freeze them for up to 2 months. The frosting is best made fresh on the day of assembly.
Why does Portillo’s cake taste so moist?
The secret lies in the butter-cocoa mixture that’s heated before mixing and the addition of buttermilk, which provides acidity that helps create an exceptionally tender crumb.
Can I turn this into cupcakes?
Absolutely! This recipe yields approximately 24 cupcakes. Reduce the baking time to 18-22 minutes and check for doneness with a toothpick.
Is there a way to make this cake less sweet?
Yes, reducing the sugar in the cake by ¼ cup and using 3½ cups powdered sugar in the frosting will decrease sweetness while maintaining texture and moisture.
