Tips for the Perfect Portillo’s Chocolate Cake
To get the best results, always use room-temperature ingredients. This ensures your batter mixes smoothly for that signature soft crumb.
Avoid overmixing, as it can make the cake dense. Also, let the layers cool completely before frosting to prevent melting or sliding.
Common Mistakes To Avoid
Avoid overbaking the cake, as it can dry out easily. Don’t skip sifting the cocoa powder and flour; this helps keep the texture light.
Also, make sure your frosting is at room temperature before spreading it, so it glides smoothly across the cake layers.

Chill the frosted cake for 15–20 minutes before slicing. This helps set the frosting for clean, professional-looking cuts.
