  • Dry ingredients and milk. Mix the flour, baking powder, and salt in a separate bowl and add to the sugar mixture 1/3 at a time, alternating with the milk and the sourdough starter.  Mix on low until just combined.  Stir in the lemon juice and lemon zest by hand.  Pour the batter into the prepared pan.

  • Bake and cool. Bake for 50-60 minutes (for the loaf pan) or 40-50 minutes (for the square pan) until golden brown and a toothpick inserted into the center comes out clean.  Place on a wire rack.  Allow to cool for about 15 minutes in the pan.

Notes

Having trouble with your cake sinking?  Try adding a teaspoon of baking soda along with the powder.  Cakes can also sink if they are underbaked: this recipe looks very browned before it bakes through.
Can be frozen if allowed to cool completely and then wrapped tightly.  Glaze after it's defrosted.
Be sure to try cinnamon sugar blueberry sourdough muffins if you love this cake!
