These brownie cupcakes are fudgy and rich, just like brownies. They are topped with the silkiest dark chocolate buttercream that literally melts in your mouth. You only need a few ingredients and little prep time to make a batch of these. Be prepared for them to disappear quickly as they are a huge crowd pleaser. By the way, have you tried my brownie cookies yet?

Whisk together the butter, sugar, eggs, and vanilla just until well combined. Sift in the flour, cocoa and salt and stir just until combined. Spoon batter into cupcake liners until almost full.
Bake until a toothpick inserted in the center comes out clean. Let cool completely.
Beat butter until soft and creamy, then sift in powdered sugar and beat until fully combined and smooth. Add chocolate and mix until combined. Then pipe or spread onto cupcakes.
Expert tips for success
- Do not use an electric mixer to mix the cupcake batter or you will mix too much air into the batter and this will make the cupcakes cakey instead of fudgy. Stir by hand with a whisk.
- Be careful not to fill the muffin cases with too much batter. Fill them about ¾ to almost full so they don't spill over the sides.
- Use a toothpick to check if they are done. It should come out lightly dirty with a few moist crumbs. If the toothpick comes out clean, the cupcakes are overbaked. They're still delicious, but the texture is more like chocolate cake.
- I recommend using good quality chocolate bars from a chocolate brand you love. Use semi-sweet chocolate with 45-60% cocoa. My favorite chocolate brands are Ghirardelli, Guittard and Lindt.
- Do not use chocolate chips or the buttercream may become grainy and less creamy.
- Allow the chocolate to cool before mixing it into the buttercream. Otherwise, the butter could become too soft, which would affect the creamy texture and make the cupcakes difficult to frost.
Yes, you can substitute 1 cup (240 ml) of oil for the butter. In general, oil results in a denser texture in baked goods compared to butter. On the other hand, butter imparts a deep, buttery flavor to baked goods. I like both, but find the butter goes better with this recipe.
Yes. Since the batter doesn't contain baking soda or baking powder, you can use any unsweetened cocoa powder. The taste and color of natural and Dutch-processed cocoa powder are different, but the results are excellent in both cases.

Remove from the oven and let cool for 10 minutes. Then remove from the pan and transfer to a wire rack and allow to cool completely before frosting.
