2 cups (414g) granulated sugar
1 cup (240ml) water
½ cup (112g) unsalted butter
1 cup (240ml) heavy cream
1 tbsp vanilla extract
1 tsp salt
2 cups (260g) all-purpose flour
2 cups (414g) granulated sugar
¾ cup (85g) natural unsweetened cocoa powder
2 tsp baking soda
1 tsp salt
2 large eggs
1 cup (240ml) milk
1 cup (240ml) vegetable oil
1 ½ tsp vanilla extract
1 cup (240ml) hot water
2 ½ cups (560g) unsalted butter, room temperature
10 cups (1150g) powdered sugar
½–¾ cup caramel sauce (from above)
Salt, to taste
½ cup toasted chopped pecans
6 oz (169g) semisweet chocolate chips
½ cup (120ml) heavy cream
In a medium saucepan, combine sugar and water. Cook over medium-low heat for 3–5 minutes, until the sugar dissolves. Add the butter and let it melt.
Increase to medium heat and bring to a boil. Do not stir. Boil until the mixture turns a deep amber color (15–20 minutes).
Remove from heat and slowly stream in the cream. Whisk continuously — it will bubble intensely.
Add vanilla and salt. Stir well.
Transfer to a container and chill. It will thicken as it cools and can be made up to 1 week ahead.
Preheat oven to 300°F (148°C). Line three 8-inch pans with parchment and grease the sides.
In a large bowl, mix all dry ingredients.
Add eggs, milk, and oil. Mix until combined.
Add hot water and vanilla; mix until smooth.
Divide the batter evenly among pans. Bake 30–33 minutes, or until a toothpick comes out with a few crumbs.
Cool cakes in pans for 10 minutes, then transfer to racks to cool completely.
Beat butter in a large bowl until creamy.
Add half of the powdered sugar and mix well.
Add ½ cup caramel sauce; mix until smooth.
Add remaining powdered sugar and mix until fluffy.
Add more caramel sauce as needed for flavor and consistency.
Season with salt to taste.
Level cake tops with a serrated knife.
Place first layer on a serving plate and spread ⅔ cup buttercream on top.
Pipe a frosting dam around the edge.
Add ½ cup caramel sauce to the center and spread gently.
Sprinkle with ¼ cup pecans.
Add second cake layer; repeat frosting, caramel, and pecans.
Place final cake layer on top. Apply a thin crumb coat.
Chill 30–60 minutes to firm up.
Frost the cake with remaining caramel buttercream.
For the ganache: place chocolate chips in a bowl.
Heat cream until just boiling; pour over chocolate. Rest 2–3 minutes, then whisk smooth.
Drip ganache around the cake edges, then spread the rest on top.
Pipe buttercream swirls around the top edge. Add caramel drizzle and pecans if desired.
Chill until ready to serve. Best enjoyed within 3–4 days.
Don’t stir the caramel while it boils — this prevents crystallization.
Use room-temperature ingredients for smoother cake batter and frosting.
Toast the pecans for deeper flavor.
Chill the cake after crumb-coating to keep layers stable during frosting.
If the caramel is too runny, refrigerate it briefly before layering.
