Baking Powder Coffee Cake

The dry ingredients (flour, baking powder, sugar, and salt) can be whisked together and stored in an airtight container for up to 1 week. The cinnamon-sugar topping can also be mixed ahead. However, the batter should be made fresh and baked immediately, as the baking powder begins working once liquid is added.

Store cooled coffee cake covered with plastic wrap or in an airtight container at room temperature for up to 2 days, or refrigerate for up to 5 days. Reheat individual pieces in a 300°F oven for 8-10 minutes to restore the crispy cinnamon-sugar topping. Can be frozen, well-wrapped, for up to 2 months; thaw at room temperature before reheating.
