From Start to Finish:
- Preheat your oven to 350°F (175°C) and line a muffin tin with cupcake liners. This will ensure that your cupcakes bake evenly and don’t stick.
- In a small bowl, melt the chocolate chips along with the stick of melted butter. Stir until smooth and set aside to cool slightly.
- In a large mixing bowl, whisk together the canola oil, granulated sugar, brown sugar, eggs, egg yolk, and vanilla extract until well combined. Pour in the melted chocolate mixture and stir until smooth.
- In another bowl, whisk together the flour, baking soda, baking powder, cocoa powder, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
- Add the sour cream and boiling water to the batter and mix until smooth. The boiling water will help to bring out the rich chocolate flavor.
- Spoon the batter into the prepared cupcake liners, filling them about 2/3 full. This allows room for the cupcakes to rise beautifully.
- Bake in the preheated oven for 18-20 minutes, or until a toothpick inserted into the center comes out clean. Allow the cupcakes to cool in the tin for about 5 minutes before transferring them to a cooling rack to cool completely.
- While the cupcakes cool, prepare the frosting. In a large bowl, beat the very soft butter until creamy. Gradually add the sifted confectioners' sugar and cocoa powder, mixing until combined. Pour in the half-and-half and mix until you reach your desired consistency. Finally, add the heaping tablespoon of dulce de leche and salt, mixing until smooth.
- Once the cupcakes are completely cool, frost them generously with the chocolate frosting using a piping bag or a spatula.
- For an extra touch of decadence, drizzle some additional dulce de leche over the frosted cupcakes and sprinkle with flaky sea salt if desired.
Notes
- Store cupcakes in an airtight container for up to 3 days at room temperature.
- Refrigerate for up to a week; let them come to room temperature before serving.
- Freeze unfrosted cupcakes for up to 3 months; thaw and frost fresh!
