Copycat Portillo’s Chocolate Cake Recipe Tips

  • Use Room Temperature Ingredients: Ensure your eggs, mayonnaise, and other ingredients are at room temperature before mixing. This helps create a smooth batter and ensures even baking.
  • Don’t Overmix the Batter: Once you add the wet ingredients to the dry, mix until just combined. Overmixing can lead to a dense texture.
  • Be Precise with the Boiling Water: The boiling water is crucial for intensifying the chocolate flavor and achieving the cake’s moist texture, so be sure to add it gradually and stir it in well.
  • Check for Doneness: Every oven is different, so check the cakes at the 30-minute mark. If a toothpick comes out clean, they’re ready.
  • Let the Cakes Cool Completely: Before frosting, make sure the cakes are fully cooled to prevent the frosting from melting or sliding off.
  • Use a Generous Amount of Frosting: Portillo’s cake is known for its rich frosting, so don’t skimp—cover the cakes generously for that classic chocolatey finish.
  • Add a Little Extra Moisture: If you prefer an even moister cake, you can add a tablespoon of sour cream or yogurt to the batter to enhance the texture.

Storing

  • Storing: Room Temperature: Once frosted, store the cake in an airtight container at room temperature for up to 3 days. Unfrosted Cake: If you’ve baked the cake without frosting, store the cake layers in an airtight container or wrap them tightly in plastic wrap. They will stay fresh for up to 5 days at room temperature.
  • Freezing: Unfrosted Cake: Wrap the cake layers tightly in plastic wrap and aluminum foil, then place in a freezer-safe bag. Freeze for up to 3 months.
  • Freezing: Frosted Cake: If freezing a frosted cake, freeze it unwrapped for 1-2 hours until the frosting sets, then wrap it tightly and store it in a freezer-safe container for up to 2 months.
  • Reheating: Let frozen or refrigerated cake thaw at room temperature for 1-2 hours before serving.

Can I make this cake without mayo? Mayo is an essential ingredient in this recipe for adding moisture and tenderness to the cake.

  • In a large mixing bowl, beat the softened butter with an electric mixer until light and fluffy (about 2-3 minutes).
  • Gradually add the cooled cocoa and milk mixture to the butter, mixing well until combined.
  • Slowly add the powdered sugar, one cup at a time, until the frosting thickens. After each addition, beat the frosting to ensure it’s smooth. Add the vanilla extract and a pinch of salt. Mix again until fully incorporated.
  • If the frosting is too thick, add a little more milk (1 tablespoon at a time) until you reach the desired consistency. If it’s too thin, add a little more powdered sugar.
  • Once your cake has cooled completely, spread the frosting generously over the top and sides of the cake.
