Tips for Success

Mix the blueberry cake batter just until combined. Overmixing can result in an overly dense or gummy texture.
For best results, let the cake cool for at least 30 minutes before slicing. This will make for nice, clean slices and less seeping of blueberry juice from cut berries.
Wrap well or place in an airtight container at room temperature for up to 3 days. But if you live in a hot or humid climate, cover and store it in the refrigerator.
