Ingredients:
- 1 ½ cups All-Purpose Flour
- 1 ¾ cups Granulated Sugar
- ¾ cup Unsweetened Cocoa Powder (Dutch-processed)
- 1 ½ teaspoons Baking Soda
- ¾ teaspoon Baking Powder
- ¾ teaspoon Fine Sea Salt
- 2 Large Eggs (room temperature)
- ½ cup Whole Milk (room temperature)
- ½ cup Vegetable Oil
- 2 teaspoons Vanilla Extract
- 1 cup Boiling Water or Hot Strong Coffee
- 1 cup Granulated Sugar (for caramel)
- ½ cup Unsalted Butter (cubed, for caramel)
- ¾ cup Heavy Cream (warmed, for caramel)
- 1 teaspoon Flaky Sea Salt (for caramel)
- 1 cup Unsalted Butter (softened, for frosting)
- 3-4 cups Powdered Sugar (sifted)
- ½ cup Cooled Salted Caramel Sauce (for frosting)
- 1-3 tablespoons Cold Heavy Cream (optional, for frosting)
Instructions:
- I. Make the Salted Caramel Sauce (Needs to Cool): Heat 1 cup of sugar in a heavy-bottomed pot until it melts and turns a deep amber colour. Do NOT stir, just swirl the pan gently.
- Carefully whisk in the cubed butter until smooth, watching for bubbling. Slowly stream in the warm heavy cream while whisking continuously. Remove from heat, stir in 1 teaspoon of salt, and pour into a heatproof bowl. Cool completely.
- II. Bake the Chocolate Cupcakes: Preheat oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners.
- Whisk together all dry cupcake ingredients (flour through salt) in a large bowl.
- In a separate bowl, whisk together eggs, milk, oil, and vanilla. Pour the wet mixture into the dry ingredients and mix until just combined.
- Carefully pour in the boiling water or hot coffee and whisk until the batter is smooth (it will be thin). Divide batter evenly among 12 liners (about 2/3 full).
- Bake for 18-22 minutes, or until a wooden skewer comes out with moist crumbs attached. Cool in the tin for 5 minutes, then transfer to a wire rack to cool completely.
- III. Prepare the Buttercream & Assemble: In a stand mixer, beat the softened butter until very pale and fluffy (about 5 minutes).
- Gradually add sifted powdered sugar, beating slowly, then increase speed. Beat in ½ cup of the cooled salted caramel sauce. Add cold heavy cream, one tablespoon at a time, if the frosting is too stiff.
- Once cupcakes are fully cooled, use a small melon baller to remove a cone from the centre of each. Spoon 1–2 teaspoons of remaining cooled caramel sauce into the cavity.
- Place the cake cone top back onto the filling. Pipe or spread the buttercream generously on top of each filled cupcake and drizzle with extra salted caramel sauce before serving.
