Cinnamon Sourdough Discard Coffee Cake

These creative sourdough discard dessert recipes turn excess starter into tender pastries with rich brown sugar cinnamon ripples. Natural wild yeast acidity tenderizes cake crumb beautifully. Every bite pairs wonderfully with morning coffee.

Whisk flour, baking powder, and salt in a bowl. Beat butter, sugar, sourdough discard, and eggs until creamy before folding in dry ingredients.

Layer batter with brown sugar streusel and bake until golden brown. Cool slightly before slicing generous squares. For more baking inspiration with real vanilla, use this vanilla paste recipe.
