Ingredients
Method
Preparation
- Preheat your air fryer to 350°F (175°C) and prepare a 12-cup muffin tin by lining each well with a paper liner.
- In a large bowl, combine the all-purpose flour, cocoa powder, baking powder, baking soda, and salt. Whisk together until well blended.
- In a separate bowl, whisk together the egg, milk, vegetable oil, and vanilla extract until blended.
- Fold the wet ingredients into the dry mixture until just smooth.
- Dissolve the espresso powder in the boiling water and whisk it into the batter.
Baking
- Divide the batter among the muffin cups, filling each about ¾ full.
- Place the muffin tin in the air fryer basket and bake for 16 to 18 minutes, or until a toothpick inserted into the center comes out clean.
- Let the cupcakes cool completely on a wire rack before frosting.
Frosting and Filling
- In a mixer, beat the softened butter, cocoa powder, half of the powdered sugar, and a splash of heavy cream until smooth.
- In a saucepan, melt the granulated sugar over medium heat until it turns golden brown. Whisk in the diced butter and heavy cream until smooth.
- Pipe frosting on top of the cooled cupcakes, create a hollow in the center for the caramel, and spoon the caramel sauce in to finish.
Notes
Avoid crowding in the air fryer, check for doneness early, and store any leftovers in an airtight container.
