Blueberry Tea Cake

The dry ingredients (flour, baking powder, and salt) can be whisked together and stored in an airtight container up to 1 week ahead. The full batter should not be made ahead, as the baking powder will lose its leavening power.

Store the cooled cake covered at room temperature for up to 2 days, or wrap tightly and refrigerate for up to 4 days. Reheat individual slices in a 300°F oven for 8-10 minutes or microwave for 15-20 seconds to restore the 'serve warm' quality. The cake can also be frozen, well-wrapped, for up to 2 months; thaw at room temperature before reheating.
