These Sourdough Corn Muffins are soft, buttery, and packed with cornmeal flavor. They’re perfect as a quick breakfast, snack, or an easy side for soups, chili, and stews. Plus, they’re a great way to use up your sourdough discard.
Preheat oven to 400°F. Line a 12-cup muffin tin with paper liners or grease the wells with butter, oil, or cooking spray.
In a medium bowl, whisk together the flour, cornmeal, baking powder, baking soda, and salt. Set aside.
1 ½ cups (180 grams) all-purpose flour, ¾ cup (120 grams) cornmeal, 2 teaspoons baking powder, ½ teaspoon baking soda, 1 teaspoon (3 grams) Diamond Crystal Kosher Salt
In a large bowl, whisk the melted butter and sugar until smooth and slightly lighter in color. Add the eggs one at a time, whisking well after each. Stir in the milk and sourdough discard until everything is combined.
½ cup (113 grams, 1 stick) unsalted butter, ¾ cup (150 grams) granulated sugar, 2 large (100 grams) eggs, ¾ cup (180 grams) whole milk, ½ cup (100 grams) sourdough starter discard
Add the dry ingredients to the wet mixture. Use a rubber spatula to gently fold the batter until just combined, being careful not to overmix. If you’re using jalapeños, fold them in now.
1-2 fresh jalapeños
Divide the batter evenly among the 12 muffin cups.
Bake for 14–16 minutes, or until the tops are golden and a toothpick inserted into the center of a muffin comes out clean.
Let the muffins cool in the pan for 5 minutes before transferring them to a wire rack to cool completely. Serve warm for the best texture.
Notes
Quick Tip: Muffins made with all butter tend to firm up at room temperature since butter solidifies as it cools. A quick warm-up in the microwave for 10-15 seconds restores their soft texture.
Storage: Store muffins in an airtight container at room temperature for up to 4 days or freeze for up to 3 months. Warm in the oven or microwave before serving for the best texture.
