Directions
<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Preheat your oven to 190°C. Line a 12-cup muffin tin with paper liners or grease well with butter. This preparation ensures your muffins won't stick and will release easily when baked.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>In a large bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, and nutmeg until thoroughly combined. Proper mixing of dry ingredients ensures even distribution of leavening agents and spices throughout your muffins.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>In a separate medium bowl, whisk the melted butter, granulated sugar, and brown sugar until smooth and no lumps remain. The melted butter coats the sugar particles, creating a moist foundation for your muffin batter.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Add eggs one at a time to the butter-sugar mixture, whisking well after each addition until fully incorporated. Then stir in the buttermilk and vanilla extract. The acidity in buttermilk activates the baking soda, helping your muffins rise beautifully.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Pour the wet ingredients into the dry ingredients and gently fold together with a spatula just until combined. You should still see a few streaks of flour—overmixing develops gluten, resulting in tough muffins.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Fold in the diced apples just until evenly distributed throughout the batter. The moisture from the apples will help keep your muffins tender and add bursts of flavor as they bake.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Use an ice cream scoop or large spoon to divide the batter evenly among the muffin cups, filling each about 3/4 full. This allows room for the muffins to rise without overflowing.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>For the topping, combine the cinnamon and sugar in a small bowl. Brush the tops of each muffin with melted butter, then generously sprinkle with the cinnamon-sugar mixture. This creates that signature sweet, crunchy crown that makes these muffins special.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>Bake for 5 minutes at 190°C, then reduce the oven temperature to 175°C without opening the door and continue baking for 15-17 minutes longer. This initial high heat helps create those beautiful domed tops. The muffins are done when a toothpick inserted in the center comes out clean or with just a few moist crumbs.</li><li class="MethodStepper"><h4 class="step-title">Step 10</h4>Allow muffins to cool in the tin for 5 minutes before transferring them to a wire rack to cool completely. This resting time allows the muffin structure to set, preventing them from falling apart when removed from the tin.</li><li class="MethodStepper"><h4 class="step-title">Step 11</h4>Store in an airtight container at room temperature for up to 3 days, or freeze for up to 3 months. To enjoy from frozen, thaw overnight or warm gently in the microwave for that freshly-baked taste.</li></ol>
