Gooey Chocolate Caramel Turtle Cake (Printer-Friendly)

A decadent chocolate sponge roll filled with gooey caramel and toasted pecans, finished with rich ganache.

# What You'll Need:

→ Chocolate Sponge

01 - 4 large eggs, room temperature
02 - 1/2 cup granulated sugar
03 - 1 tsp vanilla extract
04 - 1/2 cup all-purpose flour
05 - 1/4 cup unsweetened cocoa powder
06 - 1/2 tsp baking powder
07 - 1/4 tsp salt

→ Caramel Filling

08 - 2/3 cup thick caramel sauce
09 - 2/3 cup chopped toasted pecans

→ Chocolate Ganache

10 - 3.5 oz semi-sweet chocolate, chopped
11 - 6 tbsp heavy cream

→ Garnishes

12 - Pecan halves, for topping
13 - Extra caramel sauce, for drizzling

# How to Make It:

01 - Preheat oven to 350°F. Line a 10x15-inch jelly roll pan with parchment paper and lightly grease the surface.
02 - In a mixing bowl, beat the eggs with granulated sugar and vanilla extract using an electric mixer for 5 minutes, or until the mixture turns pale, thick, and forms ribbons when lifted.
03 - Sift together the all-purpose flour, cocoa powder, baking powder, and salt. Gently fold the dry mixture into the whipped egg base until just combined, taking care not to deflate the batter.
04 - Pour the batter into the prepared pan and spread it into an even layer. Bake for 10 to 12 minutes, until the cake springs back lightly when pressed with a fingertip.
05 - While the cake is still hot, invert it onto a clean kitchen towel dusted with powdered sugar. Peel away the parchment paper. Starting from the short end, roll the cake up snugly inside the towel. Allow it to cool completely in this rolled shape.
06 - Once fully cooled, carefully unroll the cake. Spread the caramel sauce evenly across the surface, reserving about 2 tablespoons for finishing. Scatter the chopped toasted pecans in an even layer over the caramel.
07 - Gently re-roll the cake, this time without the towel, keeping it snug but not overly tight. Place the roll seam-side down on a serving platter.
08 - Place the chopped semi-sweet chocolate in a heatproof bowl. Heat the heavy cream until just simmering and pour it over the chocolate. Let it sit for 2 minutes, then stir until the mixture is glossy, smooth, and lump-free. Allow it to thicken slightly.
09 - Pour the ganache over the cake roll, letting it cascade down the sides naturally. Drizzle with the reserved caramel sauce and arrange pecan halves on top as a garnish.
10 - Refrigerate for 20 minutes to set the ganache before slicing. For the best texture and flavor, allow the cake to come to room temperature before serving.

# Expert Advice:

01 -
  • The sponge rolls like a dream if you follow the towel trick, and you will feel like a pastry chef when it works.
  • Caramel, chocolate, and pecans together create the kind of flavor combination that makes people ask for the recipe before they finish their first slice.
02 -
  • Rolling the sponge while it is still hot is the single most important step because a cooled sponge will crack and resist shaping every time.
  • If your caramel is too stiff to spread, warm it for ten seconds in the microwave, but not so much that it melts straight through the sponge.
03 -
  • Dust your kitchen towel generously with powdered sugar before rolling, or the sponge will stick and tear when you unroll it later.
  • Toast your pecans in a dry skillet for about four minutes, shaking the pan constantly, because that brief toast transforms them from background crunch to something truly memorable.
