Use fully ripe strawberries for optimal sweetness.
For extra moisture, brush cooled cake layers with 1–2 tablespoons strawberry puree before frosting.
Store in an airtight container for up to 2 days at room temperature.
Optional: Add 1–2 tablespoons of lemon juice to frosting for brightness.
To avoid grainy frosting, strain puree through a fine sieve to remove seeds.
