Notes
Leftovers can be placed in an airtight container and stored at room temperature for up to 3 days or in the fridge for up to 5 days.* To make your own buttermilk - add a teaspoon of white vinegar or lemon juice to a measuring cup, add just enough milk (of any kind) to make 1/2 cup, stir and let stand for 5 minutes. **If using frozen rhubarb - thaw and drain well before adding it to the cake batter.
