Creating Moist & Fluffy Mocha Cupcakes with Creamy Frosting is an enjoyable process when you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and line a cupcake pan with paper liners.
2. Mix Dry Ingredients: In a large bowl, sift together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
3. Combine Wet Ingredients: In another bowl, whisk the cooled coffee, vegetable oil, eggs, vanilla extract, and buttermilk until well combined.
4. Blend Mixtures: Gradually add the wet ingredients to the dry ingredients, stirring until just combined. Be careful not to overmix.
5. Fill Cupcake Liners: Spoon the batter into the lined cupcake pan, filling each liner about two-thirds full.
6. Bake: Bake in the preheated oven for 18-20 minutes, or until a toothpick inserted into the center comes out clean.
7. Cool: Remove cupcakes from the oven and allow them to cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.
