A delightful coffee cake with a sourdough twist, perfect for breakfast or a cozy snack.
Preheat your oven to 350°F (175°C) and grease a 9-inch square baking pan.
Ensure your oven is fully preheated before placing the cake inside for even baking.
In a mixing bowl, combine the sourdough starter, melted butter, and egg until smooth.
Mix gently to avoid overworking the batter, which can make the cake dense.
In another bowl, whisk together the flour, sugar, salt, baking soda, and cinnamon.
Sifting the dry ingredients can help achieve a smoother batter.
Gradually add the dry ingredients to the wet ingredients, stirring until just combined.
Avoid overmixing to keep the cake light and fluffy.
Pour the batter into the prepared baking pan and spread it evenly.
Use a spatula to smooth the top for an even bake.
For the topping, combine the brown sugar, flour, cinnamon, and cold butter in a bowl. Use a pastry blender to create a crumbly texture.
Chill the topping mixture briefly if it becomes too soft to crumble.
Sprinkle the topping evenly over the batter.
Distribute the topping evenly for a consistent flavor in every bite.
Bake in the preheated oven for 35 minutes or until a toothpick inserted into the center comes out clean.
Check the cake a few minutes before the timer ends to prevent overbaking.
Allow the cake to cool slightly before serving. Enjoy your homemade sourdough coffee cake!
Serve warm for the best flavor and texture.
