Follow these simple steps to create your own Gooey Chocolate Caramel Turtle Cake Roll:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Line a 15×10-inch jelly roll pan with parchment paper and spray lightly with cooking spray.
2. Mix Dry Ingredients: In a bowl, sift together the flour, cocoa powder, baking powder, and salt. Set aside.
3. Beat Eggs and Sugar: In a large mixing bowl, beat the eggs and granulated sugar together until the mixture is thick and pale, about 5 minutes.
4. Add Vanilla and Milk: Stir in the vanilla extract and milk until well combined.
5. Combine Mixtures: Gradually fold in the dry ingredients until just combined. Be careful not to overmix.
6. Spread Batter: Pour the batter into the prepared pan, spreading it evenly to the edges.
7. Bake: Bake in the preheated oven for 20-25 minutes or until the cake springs back when touched.
8. Cool: Once baked, remove from the oven and let it cool in the pan for 5 minutes. Then, carefully invert it onto a clean kitchen towel dusted with powdered sugar.
9. Roll the Cake: While it’s still warm, roll the cake tightly in the towel, starting from one short end. Allow it to cool completely in the rolled position.
10. Prepare the Filling: Once cooled, unroll the cake carefully. Spread a layer of caramel sauce evenly across the cake, leaving a small border.
11. Add Pecans: Sprinkle the chopped pecans evenly over the caramel layer.
12. Re-roll the Cake: Roll the cake back up, using the towel to help guide it. Wrap it tightly in plastic wrap and refrigerate for at least 30 minutes.
13. Prepare Ganache: In a microwave-safe bowl, heat the chocolate chips until melted. Stir until smooth, adding a splash of milk if needed for consistency.
14. Drizzle Ganache: Remove the cake roll from the refrigerator and drizzle the melted chocolate ganache over the top. Allow it to set for a few minutes.
15. Slice and Serve: Once the chocolate has set, slice the cake roll into generous pieces and dust with powdered sugar if desired.
