A moist, tender sourdough cranberry cake bursting with tart cranberries and balanced sweetness. This rustic square cake has a golden top, soft crumb, and beautiful cranberry pockets throughout. Perfect for brunch, dessert, or holiday gatherings.
Preheat oven to 350°F (175°C) and grease an 8x8-inch baking pan.
In a large bowl, cream the softened butter and sugar until light and fluffy. Add the eggs one at a time, mixing well after each addition. Stir in the sourdough discard and vanilla extract until smooth.
In a separate bowl, whisk together flour, baking powder, baking soda, and salt.
Gradually add the dry ingredients to the wet mixture, alternating with the milk, and mix until just combined. Gently fold in the fresh cranberries without overmixing.
Pour the batter into the prepared pan and smooth the top evenly.
Bake for 35-45 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
Remove from the oven and allow the cake to cool in the pan for 15-20 minutes.
Dust with powdered sugar before slicing and serving.
