Ingredients
Method
Preparation
- Heat your oven to 350°F (175°C) and line a 12-cup muffin tin with paper liners.
- In a large bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt until evenly distributed.
Mixing Wet Ingredients
- In a second bowl, whisk the egg, milk, vegetable oil, and vanilla until smooth and glossy.
- Add the wet mixture to the dry and stir just until combined.
- Dissolve the instant espresso powder into the boiling water and pour it into the batter, mixing until smooth.
Baking
- Divide batter between liners, filling each about two-thirds full.
- Bake for 16–18 minutes, checking at 16 minutes until the tops spring back lightly.
- Cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before frosting.
Frosting
- Beat the softened butter until creamy. Gradually add cocoa and powdered sugar along with a splash of heavy cream until smooth.
- Adjust consistency by adding more cream if needed; it should be thick and pipeable.
Caramel
- Melt granulated sugar in a pan over medium heat until golden.
- Whisk in the diced butter, then the heavy cream, stirring in vanilla before cooling slightly.
Assembly
- Pipe a ring of frosting around each cupcake's edge, leaving a well in the center.
- Spoon caramel into each well and let it set before serving.
Notes
For best results, ensure all ingredients are at room temperature. Cool cupcakes completely before frosting to maintain the creaminess of the buttercream.
