- Unfrosted angel food cake can be stored at room temperature, covered, for up to 2 days.
- Once assembled with cream and berries, refrigerate for up to 3 days, though the texture is optimal within the first 24 hours.
- For make-ahead convenience, prepare the cake and strawberry filling separately up to 2 days in advance.
- If using frozen strawberries, thaw completely and drain excess liquid before using.
- For a dairy-free version, replace heavy cream with chilled coconut cream.
- If cake flour is unavailable, use all-purpose flour mixed with cornstarch (for each cup, remove 2 tablespoons of flour and add 2 tablespoons of cornstarch).
