Directions
<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Preheat your oven to 200°C (400°F). Line a 12-cup muffin tin with paper liners or grease well with butter. Position the rack in the center of the oven – this ensures even heat distribution for perfectly risen muffins.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>In a large bowl, whisk together the flour, cornmeal, sugar, baking powder, baking soda, and salt until well combined. The cornmeal adds wonderful texture and a subtle sweetness to these muffins, creating a beautiful contrast with the juicy blackberries.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>In a separate medium bowl, whisk the buttermilk, eggs, and vanilla until smooth. The acidity in buttermilk reacts with the baking soda to create a tender crumb and help the muffins rise beautifully. Slowly whisk in the melted butter until combined – adding it gradually prevents the cold buttermilk from solidifying the warm butter.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Make a well in the center of the dry ingredients and pour in the wet mixture. Using a rubber spatula, gently fold together until just combined – you should still see a few streaks of flour. Overmixing activates gluten and results in tough muffins, so resist the urge to stir until completely smooth!</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Toss the blackberries with 1 tablespoon of flour in a small bowl (this helps prevent them from sinking during baking), then very gently fold them into the batter, being careful not to crush the berries. A few strokes with your spatula are sufficient.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Using an ice cream scoop or large spoon, divide the batter evenly among the muffin cups, filling each about 3/4 full. Sprinkle the tops with demerara sugar for a delightful crunch and beautiful sparkle once baked.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Bake at 200°C (400°F) for 5 minutes – this initial blast of high heat helps create those beautifully domed tops. Then, without opening the oven door, reduce temperature to 180°C (350°F) and continue baking for 15-17 minutes, or until the tops are golden brown and a toothpick inserted in the center comes out with a few moist crumbs but no wet batter.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Allow the muffins to cool in the pan for 5 minutes – they're still setting up during this time – then transfer to a wire rack to cool completely. Though they're irresistible warm, allowing them to cool for at least 15 minutes lets the flavors develop and prevents them from falling apart when you bite into them.</li></ol>
