German buttercream frosting is a simple and flavorful option that is not as common in the US as it should be. Made with a pound of room temperature butter and a batch of pastry cream, the frosting is light and fluffy. The recipe allows for a lot of flexibility in terms of flavor, and you can add a lot of intensity to the frosting. The frosting can be made ahead of time, and it doesn’t require molten sugar. The only important factor to consider is the temperature of the butter. Overall, German buttercream frosting is a great option for those looking for a flavorful and easy frosting choice.
