Common Mistakes to Avoid
Creating a Frankenstein Cake can be fun, but there are common pitfalls to watch for. Here’s how to make sure your dessert turns out perfectly.
- Ignoring Room Temperature Ingredients: Using cold ingredients can affect the texture of your cake. Make sure butter, eggs, and buttermilk are at room temperature for better mixing.
- Overmixing the Batter: Mixing too much can lead to a dense cake. Mix just until the ingredients are combined to maintain a light texture.
- Not Measuring Flour Correctly: Too much flour can dry out your cake. Use the spoon-and-level method for accurate measurement.
- Skipping the Cooling Time: Frosting a warm cake can melt your buttercream. Allow the layers to cool completely on a wire rack before decorating.
