Achieving a smooth finish on a cake decorated with whipped cream involves using the right tools and techniques. Here's how to do it:
1. Prepare Your Whipped Cream Properly:
- Ensure your whipped cream is stiff but not over-whipped. Over-whipped cream can become grainy and difficult to spread smoothly. It should hold its shape but still be easily spreadable.
2. Crumb Coat is Essential:
- Apply a thin layer of whipped cream (the crumb coat) over the entire cake to trap any loose crumbs. This creates a clean base for the final layer.
- Chill the crumb-coated cake in the refrigerator for at least 15-30 minutes to allow the crumb coat to firm up. This prevents crumbs from mixing into your final layer of whipped cream.
3. Apply the Final Layer of Whipped Cream:
- Use an offset spatula or palette knife to apply a generous layer of whipped cream over the crumb coat.
- Aim for a consistent thickness.
4. Smoothing Techniques:
- Spatula Method: Hold your spatula at a slight angle (almost flat) against the side of the cake. Rotate the cake turntable (if you have one) while holding the spatula steady to smooth the sides. For the top, hold the spatula straight and pull it inwards towards the center of the cake as you turn the turntable.
- Hot Water Method: Dip your spatula in hot water, wipe it dry, and then smooth the whipped cream. The heat helps to melt the surface slightly, creating a smoother finish. Repeat as needed. Be sure to dry the spatula thoroughly each time to prevent adding water to the whipped cream.
- Piping Method: Pipe whipped cream onto the cake and then smooth the piped lines using a hot knife or spatula. This ensures a uniform starting point for a smooth finish.
5. Turntable is Highly Recommended:
- A turntable allows for even distribution of the whipped cream and makes the smoothing process significantly easier.
6. Practice and Patience:
- Achieving a perfectly smooth finish takes practice. Don't be discouraged if your first attempt isn't flawless.
Key takeaway: The key to a smooth whipped cream cake lies in a good crumb coat, proper whipped cream consistency, appropriate tools (spatula, turntable), and careful smoothing techniques.
