Ingredients

1 cup (240ml) heavy whipping cream

1 tbsp vanilla extract
1 tsp salt

2 cups (260g) all purpose flour
2 cups (414g) sugar
3/4 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 1/2 tsp vanilla

1 cup (240ml) hot water
2 1/2 cups (560g) unsalted butter, room temperature
10 cups (1150g) powdered sugar

1/2 cup – 3/4 cup caramel sauce (prepared above)

1/2 cup chopped pecans, toasted

6 oz (1 cup | 169g) semi-sweet chocolate chips
1/2 cup (180ml) heavy whipping cream (for ganache)

Instructions

Step 1: To make the caramel sauce, combine granulated sugar and water in a medium to large saucepan over medium-low heat. Cook until sugar is completely dissolved, about 3 to 5 minutes, then add butter and let it melt.

Step 2: Increase heat to medium and bring mixture to a boil. Do not whisk during this time to avoid crystallization. Boil until the caramel reaches a deep golden copper color, about 15-20 minutes. Occasionally tip the pan gently to cook evenly.
Step 3: Remove from heat and slowly pour in the heavy whipping cream in a steady stream while whisking rapidly. The mixture will bubble vigorously.
Step 4: Add vanilla extract and 1/2 teaspoon salt, whisk to combine. Adjust salt to taste. Refrigerate caramel sauce to cool; it will thicken as it chills.

Step 5: Prepare three 8-inch cake pans by lining bottoms with parchment and greasing sides. Preheat oven to 300°F (148°C).
Step 6: In a large bowl, whisk together flour, cocoa powder, sugar, baking soda, and salt.
Step 7: Add eggs, milk, and vegetable oil to dry ingredients and mix well.

Step 8: Stir in boiling water and vanilla extract until batter is smooth.
Step 9: Divide batter evenly among prepared pans and bake 30-33 minutes, or until a toothpick inserted in the center comes out with a few crumbs.
Step 10: Cool cakes in pans for 10 minutes, then remove and cool completely on racks.

Step 11: To make the buttercream, beat soft butter in a large bowl until smooth.
Step 12: Gradually add half the powdered sugar and beat until smooth and combined.
Step 13: Mix in about 1/2 cup of prepared caramel sauce until smooth.

Step 14: Add remaining powdered sugar and beat until smooth. Add more caramel sauce if needed for desired flavor and consistency. Season with salt to taste.
Step 15: Level cakes by trimming domes if necessary. Place first cake layer on a serving plate.
Step 16: Spread about 2/3 cup frosting evenly on top. Pipe a frosting dam around edge to contain caramel.

Step 17: Spread 1/2 cup caramel sauce inside the dam, then sprinkle 1/4 cup toasted chopped pecans evenly over caramel. Level the frosting dam if needed.
Step 18: Repeat with second cake layer, frosting, caramel, and pecans.
Step 19: Add final cake layer and apply a thin crumb coat of frosting over the entire cake.

Step 20: Refrigerate cake for 30 minutes to 1 hour to firm up the layers.
Step 21: Frost the outside of the cake with remaining caramel buttercream smoothly.
Step 22: To make ganache, place chocolate chips in a medium bowl. Heat heavy cream until just boiling and pour over chocolate. Let sit 2-3 minutes, then whisk until smooth.

Step 23: Drizzle ganache around cake edges and pour remaining ganache on top, spreading evenly.
Step 24: Allow ganache to set, then pipe remaining frosting around top edge. Optionally, add caramel drizzle and chopped pecans as decoration.
Step 25: Refrigerate cake until ready to serve. Enjoy chilled or at room temperature.

Tips & Variations

Toast pecans before using to enhance their flavor and crunch.
Be patient when making caramel to avoid burning; use a candy thermometer if desired.
For a more intense chocolate flavor, swap natural cocoa powder for Dutch-processed cocoa.

Use room temperature ingredients for smoother cake batter and frosting.
You can make the caramel sauce up to a week in advance and store it refrigerated.

Storage

Store the finished cake covered in the refrigerator for up to 3-4 days. Bring to room temperature before serving for best flavor and texture. Leftover caramel sauce can be refrigerated tightly sealed and gently warmed before use.

FAQs

Can I use store-bought caramel sauce instead of making my own?

Yes, store-bought caramel sauce can be used for convenience, but homemade caramel provides a richer, fresher flavor that elevates the cake.

How do I level cakes properly?

Use a serrated knife or cake leveler to trim the domed top off each cake layer. This creates a flat surface that helps the layers stack evenly and prevents the cake from leaning.
