Directions
<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Preheat your oven to 190°C (375°F) and line a 12-cup muffin tin with paper liners. This temperature gives an initial burst of heat that helps create those beautiful domed tops.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>In a large bowl, whisk together the flour, baking powder, baking soda, salt, and cinnamon until well combined. The thorough distribution of leavening agents ensures even rising throughout your muffins.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>In a separate medium bowl, whisk the sourdough discard until smooth (it should be at room temperature for best results). Add the sugar, oil, milk, eggs, and vanilla extract, whisking until thoroughly combined. The acidity in the sourdough discard will react with the baking soda, creating additional lift.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Pour the wet ingredients into the dry ingredients and fold together using a rubber spatula or wooden spoon until just combined. You'll see the batter start to bubble slightly - this is the leavening agents activating with the acidity in the discard. Stop mixing as soon as no dry flour remains – overmixing will develop gluten and create tough muffins.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Using an ice cream scoop or large spoon, divide the batter evenly between the muffin cups, filling each about 3/4 full. The scoop helps ensure even portions and baking times. Sprinkle the tops with raw sugar for a delightful crunch and sparkle.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Bake in the preheated oven for 5 minutes at 190°C (375°F), then without opening the oven door, reduce the temperature to 180°C (350°F) and continue baking for 15-17 minutes more. This temperature shift creates an initial rise (the "oven spring") followed by even baking.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Test for doneness by inserting a toothpick into the center of a muffin – it should come out clean or with a few moist crumbs, but no wet batter. The tops should be golden brown and spring back when lightly touched.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Allow the muffins to cool in the tin for 5 minutes before transferring to a wire rack to cool completely. This brief rest allows the structure to set without the bottoms becoming soggy from condensation.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>For storage, keep in an airtight container at room temperature for up to 2 days, or freeze for up to 3 months. To refresh, warm briefly in a 150°C (300°F) oven for 5-7 minutes if desired.</li></ol>
