Why we Love It

There are many reasons to love this flavorful chocolate cake.

Ingredients for the Chocolate Layers

Here is a look at the ingredients for our chocolate cake layers. The caramel flavor in this cake comes from the caramel sauce glaze as well as the caramel cream filling.

Ingredients for layers of the Chocolate Caramel Cake.

Sour Cream adds richness and improves the texture of the chocolate cake mix.

Chocolate instant pudding adds additional flavor and also creates an ultra moist, soft cake.

The sugar and all purpose flour added to the recipe extend the amount of cake batter, giving us plenty for a three layer 8 inch cake.

How to Make a Chocolate Caramel Cake

For today's cake, we are using a chocolate cake mix recipe that we really like, and pairing it with a super easy and luscious caramel cream filling.

  • Preheat the oven to 325 degrees F. Grease and Flour three 8 inch round pans. As an optional step, we also like to line the bottom of our pans with parchment paper.
  • In the bowl of your mixer, add the chocolate cake mix, all purpose flour, instant chocolate pudding mix, and sugar. Whisk to blend.

  • Add the remaining ingredients to the bowl (sour cream, vegetable oil, water, eggs, and vanilla extract). Mix on low speed for about 30 seconds.
Chocolate Cake Batter in Mixing Bowl.
  • Scrape down the sides and bottom of the bowl as needed and mix on medium speed for two minutes. The batter should look well blended.
  • Divide the cake batter between the three prepared cake pans.

  • Bake at 325℉ for approximately 20-25 minutes or until the layers spring back when lightly touched, or a toothpick can be inserted and removed with just a few moist crumbs attached. Baking times may vary depending on your oven and the type of pans used. Dark pans may bake slightly more quickly.

  • Allow the baked cake layers to cool in their pans on a wire rack for 10 minutes before turning out. Make sure that they are completely cool before frosting!

Caramel Cream Filling

This caramel cream filling or caramel "mousse" filling is a simple recipe that comes together in no time. It is a combination of vanilla instant pudding mix, heavy cream, and caramel sauce. (We used store-bought caramel.)

Ingredients for Caramel Cream Filling.

First, we combined the sifted pudding mix and heavy cream. Then, we added the caramel sauce and mixed until thick and fluffy. You can add a bit more caramel as needed.

Mixing the Caramel Cream Filling.

We recommend starting with ½ cup caramel sauce, and then add a tablespoon or two more if needed.

Since different brands of caramel sauce vary a bit with flavor and consistency, it is best to start with less and then add more as needed.

Chocolate Buttercream

We used a simple chocolate buttercream frosting which is a combination of softened butter, confectioners sugar, cocoa, a pinch of salt, and a bit of milk.

We have used this recipe for many of our chocolate cakes over the years- it is delicious! However, if you'd like more caramel flavor in this dessert, you can substitute with our homemade caramel frosting!

Assembling the Cake

To assemble the cake, place the first chocolate cake layer on the cake base or pedestal.

Then, pipe a dam of buttercream around the top edge of the cake layer, about ¼ inch from the edge.

Poke fairly shallow holes in the top of the cake layer with a fork. Then spread a thin layer of caramel sauce over the top of the layer (within the dam).

Now for the caramel cream filling! Because the surface of the cake layer is slick with caramel, it is easiest to pipe the caramel cream filling on top of the cake layer.

We did this using a disposable piping bag with the tip snipped away.

Then, use an offset spatula to lightly spread over the filling. Top with the second chocolate cake layer and repeat steps for filling.

Then, top with the last cake layer. Fill any gaps between the cake layers with buttercream frosting. (We pipe frosting into any gaps).

Then, spread a thin coat (crumb coat) of chocolate buttercream on top and around the sides of the cake.

At this point, we like to firm everything up by placing in the freezer for 15 minutes (or longer in the refrigerator).

Decorating the Cake

After chilling the crumb coated cake, we applied the second layer of chocolate buttercream and added texture with an offset spatula. Decorate however you like!

Frosting the Chocolate Caramel Cake.

We had some leftover caramel cream filling that we used to pipe a reverse shell border around the top edge of the cake, and we also did the same with chocolate buttercream. Both of these borders were piped using a star tip 21.

Recipe FAQs

Yes, because of the caramel cream filling, this cake needs to be refrigerated. However, for best flavor and texture, it is best to remove the cake from the refrigerator a couple of hours before serving.

Yes, just as with the majority of our cake recipes (from strawberry cake from cake mix to lemon cream cake, scratch white chocolate cake, and more), these layers freeze beautifully.

We wrap our cake layers individually, placing each on a foil-wrapped cake cardboard before wrapping for extra support.

To thaw, move the wrapped cake layers from the freezer to the kitchen counter. Unwrap after 30-45 minutes, once the condensation (if any) has stopped forming on the foil. Thaw to desired amount for assembly.

Some decorators prefer to put the cake together when the layers are partially frozen as they are less fragile.

Several of our cake mix recipes call for instant pudding. It not only adds additional flavor, but it creates a softer, very moist texture. Our Lemon Cake Mix recipe also calls for instant pudding in the mix.

More Cakes with Caramel

We love caramel cake recipes and have made many over the years! Some of our cakes have caramel in a starring role, as with our Caramel Cake and Caramel Vanilla Latte Cake.

Other cakes call for a caramel glaze or filling, as with our Apple Bundt Cake.

Ingredients

  • 1 15.25 oz Box Devils Food Cake Mix (We used Duncan Hines Devils Food Cake- Perfectly Moist
  • ½ cup (60g) All Purpose Flour
  • ½ cup (100g) sugar
  • 1 (3.9 oz) small box Chocolate Instant Pudding Mix. (We use Jello Brand-Do not make pudding, just add the dry powder.)
  • 1 cup (227g) Sour Cream
  • ½ cup (108g) Vegetable Oil (we use canola)
  • 1 ¼ cup (302g) water
  • 3 large eggs room temperature
  • 2 ½ teaspoons (10g) vanilla extract

For the Easy Caramel Cream Filling

  • 1 (3.9 oz) small box instant Vanilla pudding We recommend sifting the Pudding Mix (to prevent graininess)
  • 1 ¼ cups heavy cream or whipping cream
  • ½ cup (175g) Caramel Sauce (Plus a small amount more if needed. We used Ghirardelli caramel sauce.)

For the Chocolate Buttercream

  • 2 sticks (226g) unsalted butter softened (do not soften butter in the microwave)
  • 5 cups powdered sugar Plus additional as needed.
  • ¾ cup (70g) unsweetened cocoa (measure then sift)
  • ⅓ -½ cup (72g) milk plus more as needed to reach the spreading consistency you like
  • 2 teaspoons vanilla 8 grams
  • ½ teaspoon (3g) salt

Instructions

  • Preheat the oven to 325 degrees F. Grease and Flour three 8 inch round pans. As an optional step, we also like to line the bottom of our pans with parchment paper.
  • In the bowl of your mixer, add the chocolate cake mix, all purpose flour, sugar, and chocolate pudding mix. Whisk to blend.
  • Add the remaining ingredients to the bowl (sour cream, vegetable oil, water, eggs, and vanilla). Mix on low speed for about 30 seconds.
  • Scrape down the sides and bottom of the bowl as needed and mix on medium speed for two minutes. The batter should look well blended.
  • Bake at 325℉ for approximately 20-25 minutes or until the layers spring back when lightly touched, or a toothpick can be inserted and removed with just a few moist crumbs attached. Baking times may vary depending on your oven and the type of pans used. Dark pans may bake slightly more quickly.
  • Allow the baked cake layers to cool in their pans on a wire rack for 10 minutes before turning out. Make sure that they are completely cool before frosting!

Caramel Cream Filling

  • Combine the sifted vanilla pudding mix and heavy cream in a mixing bowl. I prefer to mix with a hand held mixer. If you don't have one, you can use a whisk, or the whisk attachment of a stand mixer.
  • Mix on low to medium speed until well combined and it begins to thicken. Then, add the caramel sauce. Mix on medium-high speed. The mixture will become thick and fluffy. You can add an additional tablespoon or two more if needed.
  • This makes about two cups of caramel cream filling.

Chocolate Buttercream

  • Add butter and mix on low to medium speed until smooth. Add vanilla and blend into the butter.
  • Add powdered sugar, salt, and cocoa powder.
  • Add most of the milk and mix on low speed, increasing to medium as the ingredients become incorporated.
  • Continue to mix adding remaining milk as needed. It may take 3-5 minutes to reach the smoothness and consistency you like. It will take longer if using a hand mixer. As you mix, the frosting will become very smooth. You can add additional milk (1 Tablespoon at a time) if the frosting is too thick or additional powdered sugar if too soft.

Assembling and Decorating the Cake

  • Place the first chocolate cake layer on the cake base or pedestal. Next, spoon some chocolate frosting into a disposable piping bag with the tip snipped away. Then, pipe a fairly thick ring of buttercream about ¼ inch from the edge of the cake layer. This is a dam that will keep your filling contained.
  • Next, poke some shallow holes into the top of the cake layer, followed by a thin layer of caramel sauce.
  • Next, because of the slick surface of the caramel-glazed cake, it is best to pipe on the caramel mousse filling using a disposable piping bag with the tip snipped away. Then, use an offset spatula to lightly spread over it.
  • Top with the second cake layer and repeat. Top with the third cake layer and fill in any remaining gaps between the cake layers with chocolate buttercream.
  • Crumb coat the top and sides of the cake with a thin layer of buttercream. At this point, we like to chill the cake in the freezer for 15 minutes or in the refrigerator for longer, to firm everything up. Then, add the final layer of buttercream and decorate to your liking.
  • We added texture with a small offset spatula, and then piped a top border with our remaining filling and frosting (using a star piping tip 21.) I piped two reverse shell borders.
  • This cake should be refrigerated because of the filling. However, for best flavor and texture, it is best to remove the cake from the refrigerator a couple of hours before serving.

Notes

This cake should be refrigerated because of the cream filling. It is best to use an airtight container or cake dome.

  1. I’ve asked this question before but haven’t seen an answered. Can your cakes be made in a 9x13 cake pan and how long would you recommend baking it?
    Thank you

    1. Hi Nancy- Yes, you can use this cake batter in a sheet cake pan. The same is true for any of our recipes. When using our recipes with different sizes of pans, Wilton's baking/serving chart is a good resource.

      We don't always follow their batter amounts exactly, but it is a good estimate. (For instance, they say 10 cups batter per 9x13 inch pan- but that is assuming that you want each layer to be 2 inches-- less is fine also.)

      I would double this recipe and pour into two 9x13 pans if you are wanting a two layer sheet cake with filling.

    1. Hi Mary, we haven't tried it with milk chocolate cake mix but it should be fine! Cake mixes are very forgiving. I hope you enjoy the recipe!

  2. 5 stars
    Made this once and it was a huge hit! Didn't change a thing. How many days before serving can I make this cake? (if it was posted above I may have missed it)

    1. Hi Betty- As a general rule for our cakes, we like to serve it by the third day. However, you can bake and freeze the cake layers for up to three months if you'd like to work ahead!
