If you love fudgy chocolate, gooey caramel, and that sweet crunch of toasted pecans, this cake offers them all at once. It is my go-to party sheet cake because the classic moist Texas base perfectly holds up all those decadent turtle layers, and every square vanishes fast.

Grease and flour a large rimmed baking sheet about 18 by 13 inches so the cake lifts out cleanly You want a full coating of both to prevent sticking
Mix Dry Ingredients:

Melt Butter with Cocoa:
In a saucepan over medium heat melt the butter water and cocoa powder Stir until everything is smooth and it comes to a gentle boil The flavor deepens here so do not rush
Combine Batter:

Make the Fudge Frosting:
While the cake bakes melt butter in a saucepan then whisk in cocoa powder and milk Bring just to a simmer Take off heat and whisk in powdered sugar and vanilla until creamy and lump free
Frost the Cake:
Let the cake cool about ten minutes after baking so the frosting sits on top and does not soak in Pour the warm frosting over the entire sheet and spread to the edges using a spatula
Top with Caramel and Pecans:
Drizzle caramel sauce evenly all over the frosted cake and sprinkle with chopped pecans They will stick if the frosting is still warm
Cool and Serve:
Let everything cool completely in the pan so layers can set Slice into neat squares once cool

Pecans are always my favorite ingredient here They remind me of my granddad who used to crack bags for me at the holidays. That moment when you swirl on the caramel and scatter the nuts always makes me smile because I know the real party is about to begin

Steps

Step 01

Preheat oven to 350°F (175°C). Grease and flour an 18×13-inch rimmed baking sheet to ensure easy release after baking.

Step 02

In a large bowl, thoroughly whisk together flour, granulated sugar, baking soda, and salt. Set aside.

Step 04

Pour the hot cocoa mixture over the prepared dry ingredients and stir until fully combined.

Step 05

In a separate bowl, whisk together buttermilk, eggs, and vanilla extract. Add this mixture to the batter and stir until a smooth, glossy batter forms.

Pour the batter into the prepared sheet pan and spread evenly. Bake in the center rack for 20 to 25 minutes, or until a toothpick inserted in the center comes out clean.

While the cake bakes, melt butter in a saucepan over medium heat. Stir in cocoa powder and milk, bringing just to a boil. Remove from heat and gradually whisk in powdered sugar and vanilla until completely smooth.

Step 08

Upon removing cake from oven, allow to cool in pan for 10 minutes. Pour fudge frosting over the warm cake, spreading evenly to the edges.
