Texas Turtle Sheet Cake

Did you know that today is National Chocolate Day here in the states? I absolutely LOVE chocolate, so it’s hard for me to think of a better reason to celebrate. Chocolate is one of my greatest weaknesses! In fact, a while back I wrote a blog post sharing 10 Fun Facts About Chocolate. In honor of this festive occasion, I have a drool-worthy Texas Turtle Sheet Cake recipe to share with you.

Texas Turtle Sheet Cake

Most cooks have a Texas Sheet Cake recipe in their repertoire. It’s a simple, delicious, no-fail, crowd pleasing dessert.

I have been making this cake as far back as I can remember, minus the ingredients that make this a “turtle” cake. I thought it would be fun to mix things up with some caramel and pecans. After having this version, I might not go back to the original. Although, I am tempted to try it with some salted caramel next time. Doesn’t that sound good?

Texas Turtle Sheet Cake ranks right up with Flourless Chocolate Cake and Brownie Caramel Cheesecake as one of the most sinfully decadent desserts I have ever had.

This cake is super moist, almost fudge-like in texture. I guarantee you’ll go… Mmmmmmm… after taking that first bite. Probably after the second and third bite too!

Texas Turtle Sheet Cake

2 cups granulated sugar
2 cups self-rising flour
1 cup butter
1 cup strong black coffee
1/3 cup unsweetened cocoa powder
2 eggs
1/2 cup buttermilk

chocolate frosting:
1/4 cup butter
4 tablespoons buttermilk
3 tablespoons unsweetened cocoa
2 1/2 cups powdered sugar

turtle topping:
1/2 cup chopped pecans
1 cup semi-sweet chocolate chips
1 cup caramel sauce, to drizzle

Texas Turtle Sheet Cake

1. Preheat oven to 350 degrees. Grease and flour a jelly roll pan or a 9×13-inch baking pan. If using the 9×13 pan your cake will be thicker and a little super fudge like. Both options are delicious. In a large bowl, combine self-rising flour and granulated sugar. Set aside.

2. In a saucepan, combine 1 cup butte, 1 cup coffee, and 1/3 cup cocoa. Bring to a boil, stirring constantly. Pour into the prepared dry ingredients. Using a hand-held mixer, mix on medium speed until wet and dry ingredients are thoroughly combined. Add eggs and the 1/2 cup of buttermilk. Mix on medium speed for another minute or so, until well combined.

3. Pour into baking pan, and bake for 25-30 minutes. When cake is done baking, a toothpick or fork inserted into the middle of the cake should come out clean.

4. Prepare the frosting. In a medium saucepan, combine 1/4 cup butter, 4 tablespoons buttermilk, and 3 tablespoons unsweetened cocoa powder. Bring to a boil over medium heat, stirring constantly.

5. Remove from heat and use a wire whisk to gradually mix in powdered sugar, a 1/2 cup at a time.

6. Spread or pour the warm frosting over the cake. While the cake is still warm, sprinkle with chopped pecans, and chocolate chips. Drizzle with caramel sauce.

Tip: If you don’t have buttermilk, no worries. Mix 1/2 cup milk with 2 tsp vinegar or lemon juice. Let it sit a few minutes, before you add it to the other ingredients.

If you don’t have prepared caramel sauce, try making your own slow cooker caramel sauce.

    I am sorry but I do not like your blog at this moment. I literally packed up my pans today for our move in 10 days. Had I seen this earlier I would have kept one out – these would be perfect to enjoy and relieve the stress of packing. Now I have to bookmark and wait until I move to make them. They look amazing.

    I think every day should be “Chocolate” day! And the sad thing for me is… I’m not eating sweets (about 2 months now) until Thanksgiving. I will be eating me some chocolate then. :)

  5. Sherri Harper says

    I would Lucy to make this for my family road trip for Thanksgiving. I always want to make something new. However wen it calls for caramel sauce where do I get this?

  6. says

    Good Afternoon Laura and Angela, Oh no, I cannot believe I have missed National Chocolate Day, because as a fellow chocoholic, I would have loved to share my love of chocolate.
    I was visiting Joy for Treasurebox Tuesday when I came across your photograph for a Texas Turtle Sheet Cake and I was fascinated to see what the cake was all about…. and guess what, I am certainly going to be making it…. afterall we chocolate lovers must stick together.
    Have a lovely day today.
    Best Wishes from England.

    I am dying to at least try a bite of this but being diabetic, I don’t dare. I wish someone out there could figure out how to make some of these decadent and tempting desserts safe for those of us who don’t dare try.

  17. Tamara W says

    I just finished making this. The house smells lovely and it looks to die for! I am serving it with Sunday dinner to celebrate a goal I reached. I deserve every piece I’m going to have. 😉

  18. says

    Hi – I have the cake in the oven as I type this….seems to be taking longer than the 25 – 30 minutes.
    But my question is this:
    It says to spread the warm frosting over the cake…got that…but then it says…put the choc. chips, pecans and caramel over warm cake…now does that mean you put the frosting on the cake while it is warm? Just needing an answer quickly. Don’t want to mess this up!
    Love your blog!

    • Angela says

      Oh yay! I hope you love this cake. Oven temps vary some, so just bake until a toothpick in the center comes out clean. Yes, spread the warm frosting over the cake while it’s still warm. Then right away sprinkle all the goodies over the top. Please let us know how you like it.

      • says

        Thank you so much
        Got the cake out of the oven, made the frosting, topped it and it looks awesome!
        Thanks for such a wonderful recipe.
        I’m going to use the frosting recipe now instead of my other fudge recipe!

          • says

            Well, my husband and I are on a self induced diet LOL.

            I made this for my rug hooking/punch needle gathering for tomorrow.

    I just made this using liquid coffee, the cake IS a little thin & I’m not sure 30 min will be long enough. I used cake flour & shifted the flour 1st. Waiting to see what happens. Thanks for the recipe. Any other little tips would help. How long do you boil coffee, butter & cocoa?

  20. Stephanie Romero says

    For the cocoa, do you use cocoa powder or baking chocolate?

    Also, i don’t drink coffee so could I just leave that out or would i have to make some other adjustments to the liquids in the recipe?

    • Angela says

      Hi Stephanie, yes, that is cocoa powder. Since it’s a full cup of coffee, I wouldn’t recommend simply omitting it. I haven’t tried this but I would try a cup of water and maybe bump up the cocoa powder a bit to enhance the flavor you lose from the coffee. I hope that helps.

    • Angela says

      Self-rising flour is basically all-purpose flour with baking powder and salt added. To make your own, use the following ratios: combine 1 cup of all-purpose flour with 1 1/2 teaspoons of baking powder and 1/2 teaspoon of salt.

  21. Rosie says

    You gals need to make a cookbook – seriously! I love this cake idea with the black coffee and buttermilk, and of course, this turtle topping!!!

  22. Melodee Witherspoon says

    I was wondering how long ahead can you make the Texas Turtle Cake or could you freeze it?
