Sourdough Coffee Cake Muffins

Freshly baked sourdough coffee cake muffins

These Sourdough Coffee Cake Muffins combine tangy sourdough starter with a sweet cinnamon crumb topping for a moist, flavorful treat perfect for breakfast or snack time.

Ingredients

Scale
  • 1 cup active sourdough starter
  • 1/2 cup sugar
  • 1/3 cup vegetable oil
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1 cup all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1/2 cup milk
  • For the crumb topping:
  • 1/4 cup brown sugar
  • 1/2 teaspoon ground cinnamon
  • 2 tablespoons cold butter, diced
  • 2 tablespoons all-purpose flour

Instructions

  1. Preheat the oven to 375°F (190°C). Line a muffin tin with paper liners or grease well.
  2. In a large bowl, whisk together the sourdough starter, sugar, oil, egg, and vanilla extract until smooth.
  3. In a separate bowl, sift together the flour, baking powder, baking soda, and salt.
  4. Gradually add the dry ingredients to the wet ingredients alternately with milk, mixing just until combined.
  5. Prepare the crumb topping by combining brown sugar, cinnamon, and flour. Cut in the cold butter with a fork until the mixture resembles coarse crumbs.
  6. Fill each muffin cup about 2/3 full with batter, then generously sprinkle the crumb topping on each muffin.
  7. Bake for 18-22 minutes or until a toothpick inserted in the center comes out clean.
  8. Let muffins cool in the pan for 5 minutes, then transfer to a wire rack to cool completely before serving.

Notes

For an extra indulgence, drizzle warm muffins with vanilla glaze or serve with a dollop of whipped cream.
