Super moist Chocolate Cupcakes have deep chocolate flavor and a bouncy, soft crumb, and are topped with delicious creamy chocolate buttercream frosting. The best chocolate cupcakes recipe!
Preheat the oven to 350°F. Line two 12-cup cupcake pans with 16 total liners.
In a large bowl, whisk together flour, cocoa powder, espresso, baking powder, baking soda, and salt.
In a medium bowl, whisk together oil, eggs, granulated sugar, vanilla, and buttermilk until well mixed.
Pour wet mixture into dry mixture bowl, scraping down the sides of the bowl to get any last wet bits. Whisk together until just combined and no flour patches remain, being careful not to overmix.
Fill cupcake liners about halfway with batter, any more than that and it will overflow. Bake for 18-22 minutes, until a toothpick inserted in the center of a cupcake comes out clean. Mine took 20 minutes.
Allow cupcakes to cool in the pan for 8-10 minutes, then transfer to a cooling rack to cool completely.

Notes
Storing Instructions: Store chocolate cupcakes in an airtight container in the refrigerator for 3-4 days, or 1-2 days at room temperature. Best when frosted right before serving, but ok when done in advance.
Freezing Instructions: Freeze frosted cupcakes in a freezer-friendly, airtight container for 1-2 months. Allow to thaw for about 20 minutes at room temperature before enjoying.
