Directions
- Make the caramel pecan filling. In a medium saucepan over medium heat, melt the 2 tbsp butter. Add pecan halves and toast for 2–3 minutes until fragrant. Remove and set aside. In the same saucepan, slowly heat 2 cups sugar, stirring occasionally, until it melts into a deep amber caramel. Carefully whisk in the salted butter until fully melted—it may bubble vigorously. Slowly pour in the room-temperature heavy cream while whisking. Remove from heat and stir in vanilla (optional), salt, and toasted pecans. Let cool completely; it will thicken as it sits.
- Prepare the salted caramel sauce. In a clean saucepan, heat 1 cup granulated sugar over medium heat until fully melted and amber in color. Add the cubed butter and whisk until smooth. Slowly add the heavy cream and whisk again until combined. Remove from heat and stir in salt and vanilla if using. Allow the caramel to cool fully before using in the frosting.
- Preheat your oven and prepare pans. Set your oven to 175°C (350°F). Grease and line three 8-inch (20 cm) round cake pans with parchment paper.
- Mix the dry ingredients. In a bowl, whisk together the flour, cocoa powder, salt, baking soda, and baking powder. Set aside.
- Beat the butter and sugar. In a large bowl, cream the softened butter and sugar together for 3–4 minutes until pale and fluffy. Add the eggs one at a time, mixing well after each.
- Add the sour cream and flavorings. Mix in the sour cream, vanilla, and instant coffee granules. The coffee won’t make the cake taste like coffee—it simply deepens the chocolate flavor.
- Combine dry ingredients with buttermilk. Add the dry mixture in three parts, alternating with the buttermilk, mixing gently until the batter is smooth and thick.
- Bake the layers. Divide the batter evenly among the three prepared pans. Bake for 28–32 minutes, or until a toothpick inserted into the center comes out clean. Let the cakes cool in the pans for 10 minutes, then transfer to a rack to cool completely.
- Make the salted caramel buttercream. Beat the softened butter for 2–3 minutes until light. Add the powdered sugar in several additions. Pour in ¾ cup of the cooled caramel sauce and whip until smooth. Add heavy cream or milk (1 tbsp at a time) until the frosting becomes silky and spreadable.
- Make the ganache drip. Heat the heavy cream until steaming, then pour over the chocolate chips. Let sit for 2 minutes, then stir until glossy and smooth. Cool slightly before dripping.
- Assemble the cake. Place the first cake layer on your serving board. Spread a thin layer of buttercream, then spoon on some caramel pecan filling. Add the second layer and repeat. Place the third layer on top and coat the entire cake in caramel buttercream.
- Add drip and garnish. Using a spoon or squeeze bottle, add caramel drip and chocolate ganache drip around the edges. Sprinkle chopped pecans on top and decorate with whole pecans for a stunning finish.
