Pastry cakes can contain eggs, but not all pastry cakes do. The inclusion of eggs in a pastry cake depends on the specific recipe being used. Eggs are a common ingredient in many cake recipes, as they provide moisture, structure, and richness to the final product. However, there are also eggless cake recipes available that use alternative ingredients to achieve similar results.
If you have specific dietary restrictions or preferences, it's always best to consult the recipe or speak with the baker or pastry chef who will be preparing the cake. They can provide information on the ingredients used and help you find a suitable option that aligns with your needs.
