Turtle Cake
Turtle Cake is probably the richest, sweetest, most decadent cake recipe I make. It is chocolate and sugar on steroids! Seriously. Turtle Cake starts with a German Chocolate cake mix. You bake half of the batter in a 9×13″ baking dish. After that bakes you spread an incredibly delicious and high calorie caramel filling that includes butter and sweetened condensed milk on top.

After that, you top the caramel filling with chocolate chips and pecans. Then you spread the remaining cake batter over top and finish baking the cake. Wow! But that’s not all. Then you spread a luscious and creamy Chocolate Marshmallow Frosting over top.
Uh, yeah….this is one of those 10,000 calories a slice cakes….well, perhaps not quite that bad, but you get what I mean. Turtle Cake is reminiscent of Turtle Candies. Gloriously rich!
I got this delectable recipe from my best recipe exchange friend, Mimi Pownall, in 1984, when she asked me to type her recipes into a cookbook on what was then a new phenomenon–personal computers and word processing! Yay. I remember her telling me later that I had left out the butter in the filling. So I hand-wrote that into my cookbook.
When I did get around to making this recipe not too long afterwards, we were all just in awe of the taste. I remember taking this cake with us as a birthday cake for our oldest son one year when we went camping with friends over his birthday. Everyone oohed and awed over it. Mimi always said this cake didn’t need any icing because it was in the middle of the cake, but I’ve always served it with icing because it looked better!
Turtle Cake is still one of our favorite cakes, but it really is rich and sweet. I served it for company last Sunday along with vanilla and chocolate chip cookie dough ice cream. Ahem, did I say this cookie is rich and high in calories? Especially if you have it with a few scoops of chocolate chip cookie dough ice cream! Nevertheless, it is one of those treats we indulge in on special occasions.
Here are a couple of recommendations when making this cake. Get your caramel layer going first. Unwrap all the caramels and put in a saucepan over LOW heat with the condensed milk and butter. If you try to speed up the process and cook on a higher heat the caramels will almost always scorch! Ugh.
It usually takes a full 15 minutes to get the caramels to completely melt down and that’s with me pressing the caramels against the edge of the saucepan with a spoon to make sure all of them dissolve. You want the caramel filling ready to go when your cake layer is baked. You can mix up the cake ingredients rather quickly and get the cake in the oven in less than 5 minutes.
Second, even though you only bake half the batter, make sure the cake is fully cooked before you try to pour the caramel sauce over top. It really doesn’t set up well if the cake is still gooey on the bottom. Test with a toothpick. Even though you should only have to cook it for 15 minutes, it took my oven 18 minutes before the cake was baked completely.
Third, make sure you spray the sides (and not just the bottom of your cake pan/dish). Otherwise the caramel layer will stick to the sides of the dish and be hard to get out.
Fourth, don’t skimp on ingredients. Use a high quality German Chocolate cake mix, real butter (no margarine!), caramels, chocolate chips, etc., for best results.
If you’re looking for a super-duper cake recipe that will wow your guests, then give Turtle Cake a try. I usually don’t serve it with more caramel sauce (or chocolate sauce) because it is so rich that that is really overkill. But feel free to go overboard if you wish! 🙂 But don’t say I didn’t warn you–this cake is addictive.
Turtle Cake is one spectacular cake. But don’t say I didn’t warn you–this cake is highly addictive! It’s perfect for birthdays, anniversaries and special occasions.
Rich, decadent and a chocolate lover’s delight!
The filling is made up of caramels, chocolate chips and pecans. Yum.
Here’s what I did.
I used these ingredients for the cake.
Mix the German Chocolate cake mix with eggs, water and oil.
Mix with an electric mixer until smooth.
Spray the bottom and sides of a 9×13″ glass baking dish with cooking spray. Spread HALF of the chocolate cake batter into the prepared pan. Bake at 350 for approximately 15-18 minutes or until the cake is set and a toothpick inserted in the center comes out clean.
Meanwhile, unwrap all your caramels. (I actually do this step first). Add butter and condensed milk and stir until caramels have completely melted about 15 minutes over LOW heat. Don’t try to do this over medium heat or the caramels scorch easily. Then your cake will taste burnt!
Here the caramels are completely dissolved. Set aside, but be ready to pour over the cake when it’s done.
Remove cake from oven after it tests done.
Pour caramel filling slowly and evenly over the cake so that it spreads and fills in each place. This is easier than trying to spread it with a knife.
Sprinkle evenly with chocolate chips.
Now sprinkle evenly with chopped pecans.
Cover with remaining cake batter. You will barely have enough. Spread the cake batter the best you can over top of the filling ingredients.
Bake about 20-25 minutes or until a toothpick inserted in center comes out clean. Cool completely.
To make frosting: Mix powdered sugar, cocoa and salt in a mixing bowl. Add just enough milk to barely make the mixture spreadable.
You can see I use a whisk and the chocolate mixture is pretty thick. Now add Crisco shortening and marshmallow creme.
Whisk ingredients to combine. Now the frosting is of a nice spreading consistency.
Spread Chocolate Marshmallow Frosting over top of the Turtle Cake.
This cake is easier to keep in the baking dish rather than trying to remove it and put it on an oblong serving plate. If desired, serve with additional caramel sauce.
Look at that ooey, gooey caramel layer in the middle. Yum!
Serve Turtle Cake with ice cream or more caramel sauce–if you dare!
Here’s the recipe.

I’ve made this cake many times over the years with slight changes. I use 14 ounces of caramels and no chocolate chips. I put nuts on top of the cake. I find it rich enough without frosting. It’s one of my personal favorites which generally never goes to waste.

Hi Cynthia. Yes, it is a very versatile recipe. The original recipe I got from a friend did not actually include icing. It is truly rich enough without it! I do love it with chocolate chips, though. 🙂
Turtle love!

Dear, dear Teresa.
I can’t thank you enough. I made your turtle cake first for my brother’s birthday. Then for my family (seeing the assembly of all the delicious ingredients, I just had to eat it too.) This cake should be called ‘Better than Turtles Cake’ b/c I think your cake recipe totally blows the candies. In the last decade or so I’ve become very focused on calorie choices so I while I do eat things like turtle cake, I would not eat the candy b/c the candy is not worth the calorie load and the cake IS TOTALLY WORTH IT! You’ve outdone yourself. Congrats. I will take much pleasure perusing the rest of your recipes collection.

So glad you loved the recipe! I’ve been making this vintage recipe for decades and it can’t be beat. It is so rich, though, that a small piece will do! 🙂

Can you use the kraft Carmel bits instead of the carmels for the cake? Thanks
Teresa

Hi, Gayle. I don’t think you will get enough of the flavor or texture with that substitution. Sorry.

Can you use crisco oil instead of the crisco shortening? Are what could you use? Thanks
Teresa
March 22, 2021 at 5:53 am
Hi, Gayle. I’m not sure if you’ll get the fluffiness in the texture of the recipe if you substitute oil for the shortening in the icing.

Hello! I’m in the process of making this decadence (currently in the oven). Was wondering about the icing instructions. Your direction indicate to use “1/2 box OR 2 cups” of confectioners sugar. But a single box is 2 cups. Soooooo, can you please clarify? TIA!
Teresa
March 1, 2020 at 9:35 am
Hi, Erni, Normally a 16-oz. box would be 2 cups. But I think it takes three or four cups to get an actual 16 ounces in powdered sugar. I would measure out eight ounces (on a scale if you have it). (Sorry, this is one of those old vintage recipes where things were measured differently than today).

I make a version of this often but my recipe has evaporated milk instead of sweetened condensed and for the last two years on my daughter’s birthday I have been melting another bag of caramels and everything that goes into the middle layer and pouring that over the top and yes it is so rich a little goes a long way! My family love it. I have never had it with the marshmallow buttercream icing but I can’t wait to try it!
Teresa
December 11, 2019 at 11:47 am
Hi, Lenoria. I love the idea of more caramels and chocolate dumped on top! I’m sure it’s so rich and decadent that way.I hope you enjoy it with the icing this way too. I have heard of recipes using evaporated milk instead of condensed. The condensed milk sure does amp up the flavors though. 🙂

Teresa, I’m unsure as to which type of Crisco shortening (liquid or solid that comes in either the can or solid quarters) to use in the frosting recipe. Can you u please clarify. Thank you.
Teresa
September 25, 2019 at 4:44 pm
Hi Gwen, I always use the solid Crisco shortening in a can. Hope this helps.

So, 1 11 oz bag of caramels? So, 40 total caramels? I’m asking because in the picture of ingredients it shows 2 bags. Thank you!
Teresa
March 18, 2016 at 7:04 am
Hi, Sheila. I think when I originally took the pictures I wasn’t sure how many caramels were in each bag. You need 40 caramels. I believe I found that I could get that amount in an 11-ounce bag and not have to use a second bag. Hope this helps.

I assume the filling doesn’t have to be baked right? I’m asking because I was going to make a smaller layered round cake. Thanks , looks good!
Teresa
August 28, 2015 at 10:53 am
Alexandra, actually after baking half of the cake, you top the baked cake with the caramel sauce, pecans and chocolate chips. Cover the remaining cake batter and rebake it again for the final cooking time. So yes, the filling is baked even though it is pre-cooked on top of the stove. Hope you enjoy it.

Hi Teresa,
I have made numerous recipes of yours and they have all been fantastic. I would love to make a layer cake for two people only or a cake for two people. do you have any recipes or advice on how to do so?
Teresa
June 10, 2015 at 2:43 pm
Hey, Veronica. That’s difficult. You would probably have to have special pans. But this is what I do. I bake a cake and then either give the rest away or freeze it. You can even freeze it already sliced in separate containers if you desire, so that you pull out just the amount you want. Do you have 4-inch or 6-inch round cake pans? Maybe you can purchase some at a restaurant supply since bakers use them. If you have some of those, I would recommend cutting a recipe in half (same for the icing), and give it a whirl. Start with a basic chocolate cake or vanilla cake and see how it works. Then you can expand it out to other recipes as you see fit. Please let me know how it turns out (and where you found the cake pans). 🙂
