Step-by-Step Instructions

Step 1: Prepare the Baking Pan

Preheat your oven to 350°F (175°C). Grease and flour a 9x13-inch baking pan to prevent sticking.

Step 2: Mix the Dry Ingredients

In a large mixing bowl, whisk together the self-rising flour and sugar. Set aside.

Step 3: Heat the Wet Ingredients

In a medium saucepan, combine:

  • 1 cup butter
  • 1 cup brewed coffee
  • 1/3 cup unsweetened cocoa powder

Cook over medium heat, stirring frequently, until the mixture just reaches a boil. Remove from heat.

Step 4: Combine Wet and Dry Ingredients

Carefully pour the hot chocolate mixture into the bowl with the dry ingredients. Using a hand mixer, beat on medium speed until fully combined.

Step 5: Add Eggs and Buttermilk

Add 2 eggs and 1/2 cup buttermilk to the batter. Beat for another minute on medium speed until smooth and well mixed.

Step 6: Bake the Cake

Pour the batter into the prepared baking pan and spread evenly.
Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.

Step 7: Make the Chocolate Icing

While the cake is baking, prepare the icing:

  1. In a small saucepan, melt 1/4 cup butter over medium heat.
  2. Stir in 4 tablespoons buttermilk and 3 tablespoons unsweetened cocoa powder.
  3. Bring to a gentle boil, stirring continuously.
  4. Remove from heat and gradually whisk in powdered sugar, 1/2 cup at a time, until smooth.

Step 8: Ice the Cake

Once the cake is done, immediately pour the warm icing over the hot cake, spreading evenly.

Step 9: Add the Turtle Topping

While the frosting is still warm, sprinkle chopped pecans and chocolate chips evenly over the cake.
Drizzle 1 cup of caramel sauce on top. Let the cake cool slightly before slicing.

Pro Tips for the Best Texas Turtle Sheet Cake

  • Use Freshly Brewed Coffee: The coffee enhances the chocolate flavor without making the cake taste like coffee. If you prefer, you can use hot water instead.
  • Substituting Buttermilk: No buttermilk? No problem! Mix 1/2 cup of milk with 2 teaspoons of vinegar or lemon juice and let it sit for 5 minutes before using.
  • For Extra Gooeyness: Warm the caramel sauce slightly before drizzling it over the cake to ensure an even, melty spread.
  • Make It Ahead: This cake actually tastes even better the next day as the flavors meld together. Store covered at room temperature for up to 3 days.

Serving Suggestions

  • Pair with a cold glass of milk or a scoop of vanilla ice cream for a truly decadent dessert.
  • Add a sprinkle of sea salt on top of the caramel for a sweet-and-salty twist.
  • Serve warm for a melty, gooey experience or chilled for a chewy, fudgy texture.
