Recipe FAQs

How do I get the buttercream to hold its shape when piping?

Ensure the buttercream is well chilled but still soft enough to pipe smoothly. Using firm, but not cold, frosting helps maintain defined shapes.

Can I prepare the cookies ahead of time?

Yes, thoroughly cooled cookies can be stored in an airtight container for up to three days before decorating to keep freshness.

What tips work best for the mermaid tail details?

Star or petal piping tips create textured scales and flowing lines that mimic the tail's natural look.

How do I achieve the shimmering effect on the sweets?

Lightly dust edible shimmer powder or glitter over the frosting once piped to add a gentle sparkle.

Are there any ingredient substitutions recommended?

Butter can be substituted with margarine for a dairy alternative, but this may slightly alter texture and flavor.
