Step 1: Preheat the Oven. Start by preheating your oven to 350°F (175°C). This ensures that your cupcakes bake evenly.
Step 2: Prepare the Cupcake Tin. Line your cupcake tin with cupcake liners. This not only makes cleanup a breeze but also gives a lovely presentation.
Step 3: Mix Dry Ingredients. In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, cocoa powder, baking soda, and salt until well combined.
Step 4: Combine Wet Ingredients. In a separate bowl or measuring cup, combine the warm coffee (or buttermilk), vinegar, olive oil, egg, and vanilla extract. Mix well.
Step 5: Combine Wet and Dry Ingredients. Pour the wet mixture into the dry ingredients. Gently stir until just combined, being careful not to overmix. A few lumps are okay!
Step 6: Fill the Cupcake Liners. Using a scoop or spoon, fill each cupcake liner about two-thirds full with batter. This allows room for the cupcakes to rise.
Step 7: Bake. Place the cupcake tin in the preheated oven and bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean.
Step 8: Cool. Once baked, remove the cupcakes from the oven and let them cool in the tin for about 5 minutes. Then transfer them to a wire rack to cool completely.
