Hi Dear!
Your current frosting sounds like a great base, but if you're aiming for that bakery-style finish, you might want to try adding a little butter or cream cheese to give it a richer, smoother texture. Here's a simple recipe you could try:
Bakery-Style Frosting
1/2 cup unsalted butter, softened
2 cups powdered sugar
2-3 tablespoons milk or cream
1 teaspoon vanilla extract (or any flavoring you like)
Cream the butter until smooth, then gradually add the powdered sugar. Mix in the milk or cream until you reach your desired consistency, and finally, add the flavoring. This should give your ricotta egg biscuits that perfect bakery-style frosting!
Let me know how it turns out, and
happy baking!
