Line the pan: Parchment paper makes cooling and clean cuts easier.
Measure accurately: Spoon and level flour so the crumb stays fudgy, not cakey.
Cool fully: Decorating on a warm slab softens frosting and tips the trees.
Pipe with a star tip: Small, tight stars give crisp branches and height.
Warm the knife: A quick wipe and warm blade make smooth cuts.
