Sourdough Chocolate Cake blends rich cocoa with the unique tang of sourdough starter, creating a moist, tender texture and deep flavor. This cake uses natural fermentation to enhance taste and softness, making it stand out from traditional chocolate cakes. Easy to make and perfect for sharing, it offers a delicious twist that highlights the magic of sourdough in baking.
Preheat your oven to 350°F (175°C). Grease a 9-inch cake pan and lightly dust it with flour or line it with parchment paper.
Mix dry ingredients:
In a large bowl, sift together the flour, cocoa powder, espresso powder, baking soda, and salt. Whisk these dry ingredients to combine evenly.
Combine wet ingredients:
In a separate bowl, whisk together the sourdough starter, milk, vegetable oil, sugar, eggs, and vanilla extract until smooth and well blended.
Bring it all together:
Slowly add the dry ingredients to the wet mixture, folding gently with a spatula or using a mixer on low speed. Stir just until there are no more streaks of flour avoid overmixing.
Bake the cake:
Pour the batter into the prepared cake pan. Bake in the preheated oven for 35-40 minutes, or until a toothpick inserted into the center comes out clean. Remove the cake from the oven and let it cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely.
Prepare the topping:
While the cake cools, heat the heavy cream and butter together in a small saucepan over low heat until melted and combined. Remove from heat and whisk in the Dutch cocoa powder and sweetened condensed milk until smooth and glossy.
Finish and serve:
Once the cake is completely cool, pour the chocolate topping evenly over the cake, spreading with a spatula if needed. Let it set for about 15 minutes before slicing and serving.
