Directions
<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Preheat your oven to 180°C (350°F) and line a 12-cup muffin tin with paper liners. Position the rack in the middle of the oven for even baking.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>In a large bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt. Sifting the cocoa powder will help eliminate any lumps and create a smoother batter. Add the chocolate chips and toss to coat them in the dry mixture (this prevents them from sinking during baking).</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>In a separate bowl, whisk together the eggs and sugar until well combined and slightly lighter in color, about 1 minute. Add the vegetable oil, buttermilk, and vanilla extract, whisking until thoroughly incorporated. The oil (rather than butter) will ensure your muffins stay moist for days.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Pour the wet ingredients into the dry ingredients and fold gently with a spatula until just combined. Stop mixing as soon as no dry flour is visible - overmixing will develop gluten and result in tough muffins. The batter will be quite thick.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Divide the batter evenly among the 12 muffin cups, filling each about 3/4 full. Use an ice cream scoop for uniform portions that will bake evenly.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Bake for 16-18 minutes, or until a toothpick inserted into the center comes out with just a few moist crumbs (not wet batter). Don't overbake or they'll dry out! Let the muffins cool in the tin for 5 minutes before transferring to a wire rack to cool completely.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>While the muffins are cooling, prepare your Olympic rings decoration. Divide the white chocolate into 5 equal portions in separate heatproof bowls. Microwave each bowl in 20-second intervals, stirring between each, until just melted (overheating will cause the chocolate to seize).</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Add a few drops of the appropriate food coloring to each bowl of melted chocolate (blue, yellow, black, green, and red) to create the Olympic ring colors. Stir until each is evenly colored. Transfer each colored chocolate to a small piping bag or zip-lock bag with a tiny corner snipped off.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>Once muffins are completely cool, pipe five interlocking rings on top of each muffin to represent the Olympic symbol. Start with the blue, black, and red rings on top, followed by the yellow and green rings underneath. Allow the chocolate to set completely before serving or storing.</li><li class="MethodStepper"><h4 class="step-title">Step 10</h4>Store in an airtight container at room temperature for up to 3 days, or freeze for up to 3 months. To refresh them, warm slightly in the microwave for 10-15 seconds if desired.</li></ol>
