Caramel Apple Cake


Sep 12

Inspired by the popular Rocky Mountain Chocolate Apple Pie Caramel Apple, my new Caramel Apple Cake is made up of caramel cake layers, apple pie filling, salted caramel, white chocolate buttercream, and a light dusting of brown sugar and cinnamon.

The other day in one of my cake classes, someone asked me how I come up with my cake flavors. She said, “do you just eat other dessert and think, ‘this can be cake’ ?”. Yes! That’s exactly what I do! It’s how I came up with my Tonight Show Cake, my Everything but the Kitchen Sink Cake, my Peach Crisp Cake, and so many more.

I get so much joy and satisfaction from creating cake flavors that will remind you of other non-cake desserts. I love when it works out as perfectly as this Caramel Apple Cake, inspired by the Apple Pie Caramel Apple by Rocky Mountain Chocolate Factory.

The Makings of My Caramel Apple Cake

I recently made my Tonight Show Cake for a wedding. While eating scraps of the caramel cake layers, I started thinking of new flavor combinations for the caramel cake. I have only used it in the Tonight Show Cake. (Which is a total crime because the caramel cake is amazing). The caramel cake is actually a Milk Bar recipe, and there’s nothing I’d do to change it. It’s tender, moist and super flavorful, thanks to a huge amount of dulce de leche in it. (Not sure you’ll find a bigger fan of Christina Tosi and Milk Bar than me).

As I was thinking about what to pair the caramel cake with, the Rocky Mountain Chocolate Factory Apple Pie Caramel Apple came to mind. It’s my favorite caramel apple and sounded like the perfect treat to recreate in cake form.

With Milk Bar already on my mind, I decided to use their apple pie filling from the Milk Bar Apple Pie Cake. I then added my white chocolate frosting, salted caramel and a light dusting of brown sugar and cinnamon – just like the caramel apple.

Stacking The Cake

A couple notes about stacking and frosting this cake:

First, each cake layer needs to be completely level. I use a cake leveler to cut each of my layers after they’ve baked and cooled. To get the caramel to stay on top of the cake, and not drip down the sides of the cake, you’ll want the cake to be completely even.

Second, you’ll frost each cake layer with a little bit of frosting and then pipe a rim around the edges so the apple pie filling doesn’t spill out. You want to secure the filling into the frosting by patting down the apples with the back of a fork. You’ll then drizzle caramel over the apples and repeat with the other three layers. Remember, the last layer always gets placed crumb-side (top-side) down.

After stacking the cake, you’ll apply a thin layer of frosting around the entire cake to lock in the crumbs. Put it in the freezer for 10 to 15 minutes to set before frosting the rest of the cake.

When the crumbs are locked in, you’re ready to frost the rest of the cake. To apply the brown sugar and cinnamon mixture, just put some in your hands and gently let the mixture fall from your hand to the side of the cake. (I have a video on Instagram to show you what I’m talking about).

Alright, time to pick those apples and get backing. This Caramel Apple Cake is going to the perfect addition to your Fall gatherings!

Enjoy!

  • 2 teaspoons ground cinnamon
  • 1/2 teaspoon kosher salt

  • 1 teaspoon vanilla
  • 8 ounces white chocolate, melted and cooled slightly
  • 4 tablespoons heavy whipping cream

Instructions

For the Caramel Cake

  1. Heat the oven to 350 degrees F. Spray four 8-inch round cake pans with nonstick spray, line with parchment paper and spray again. Set aside.
  2. Combine the butter and sugar in the bowl of a stand mixer fitted with the paddle attachment and cream together on medium-high speed for 2 to 3 minutes.
  3. Scape down the sides of the bowl, add the dulce de leche, and beat on high for another 3 minutes.
  4. Scrape down the bowl again. Add the eggs and yolk, one at a time, beating on medium-high for one minute after each addition. After you add the last egg, beat on high for 4 more minutes. Scrape down the sides of the bowl once more.
  5. On medium-high speed, stream in the buttermilk, oil and vanilla very slowly. This process should take 3 to 4 minutes to add. Don't rush the process. You're basically forcing too much liquid into an already fatty mixture that doesn't want to make room for that liquid. There should be no streaks of fat or liquid and the mixture should look smooth and not curdled. Stop the mixer and scrape down the sides of the bowl.
  6. On very low speed, add the cake flour, baking powder, and salt. Mix for 45 to 60 seconds, just until your batter comes together and any remnant of dry ingredients have been incorporated. Scrape down the sides of the bowl. If you see any lumps of cake flour in there while you're scraping, mix for another 30 to 45 seconds.
  7. Evenly distribute the cake batter in the four pans, about 18 to 19 ounces of batter in each. 
  8. Bake the cake for 23 to 25 minutes. The cake will rise and puff, doubling in size, but will remain slightly buttery and dense. To check if it's done, gently poke the edge of the cake with your finger. The cake should bounce back slightly and the center should no longer be jiggly. Leave the cake in the oven for an extra 3 to 5 minutes it if doesn't pass this test.

For the Apple Pie Filling

  1. Fill a medium bowl halfway with cold tap water. Juice the lemon into it. Fish out and discard any seeds. you will use this lemon water to keep your apple pieces looking fresh and pert.
  2. Peel the apples, then halve and quarter them. Put each apple quarter on its side and cut a small slice down the length of the apple to remove the seeds and core. cut each apple quarter lengthwise into thirds and then crosswise into fourths, leaving you with 12 small pieces from every apple quarter. Transfer these pieces to the lemon water as you go.
  3. When you’re ready to cook, drain the apples (discard the lemon water) and combine them in a medium pot with the butter, brown sugar, cinnamon, and salt. Slowly bring to a boil over medium heat, using a spoon to gently stir the mixture as it heats up and the apples begin to release liquid. Reduce the heat and simmer the apples gently for 3 to 5 minutes. Be careful not to cook the apples so much that they turn into applesauce.
  4. Transfer to a container and put in the fridge to cool down. Once completely cooled, the filling can be stored in the fridge in an airtight container for up to 1 week; do not freeze.

For the White Chocolate Buttercream

  1. Pour the white chocolate chips into a microwave safe bowl and microwave for 60 seconds. Stir and, if needed, microwave for another 30 seconds. Set aside to cool slightly.
  2. In a stand mixer fitted with a paddle attachment, cream the butter on medium-high speed for about two minutes.
  3. With the mixer on low speed, slowly add the sifted powdered sugar until incorporated. Scrape down the sides of the bowl and continue to mix for another minute.
  4. Slowly add the cooled white chocolate while mixing on medium-low speed.
  5. Add the heavy cream, one tablespoon at a time. Once the cream is incorporated, add the vanilla and increase the speed to medium-high and beat the frosting for five minutes, until light in color and texture. 

For the Salted Caramel

  1. Mix the sugar, water and corn syrup in a small saucepan over medium heat.
  2. Bring the mixture to boil, but DO NOT STIR! (Stirring encourages crystallization). Let the mixture cook until it turns to a golden brown/amber color. It happens quickly, so keep an eye on it.
  3. Remove the caramelized sugar syrup from the heat and very slowly stir in the cream, pouring it in little by little, to temper the cream and sugar syrup. If you pour it in all at once, your sugar will turn into hard candy. You can start adding more and more as you go along.
  4. Once the cream is mixed in, add the salt, vinegar and vanilla. Stir to combine and then set aside to cool to room temperature before using.    

Assembly

  1. Place the first cake layer, top side (crumb side) up. Apply a thin layer of frosting over the top of the cake layer and pipe a rim of frosting around the edge of the cake layer. Fill the center with the apples (not using any of the liquid from the mixture). Pat the apples down with the back of a fork to set them in place and help create a level surface to stack the next cake layer on. Drizzle some salted caramel over the apples.
  2. Repeat step 1 with the next two cake layers. Place the final cake layer top side down over the last layer of filling.
  3. Apply a thin coat of frosting around the entire cake to create crumb coat. This layer of frosting does not need to look perfect. It's just to lock in the crumbs. Freeze the cake for 10 to 15 minutes to set the crumb coat.
  4. After the crumbs are locked in, you can frost and decorate the cake. 
  5. For the caramel on top, I pour the caramel in the center and gently spread it to the edges with my offset icing spatula.

  1. Hi Courtney! If I use vegetable oil instead of grapeseed, do I still use 1 cup? Also, can you find dulce de leche in a grocery store like Kroger?

    1. I recommend grapeseed oil. It’s a lighter oil that vegetable oil or canola oil and creates a lighter, fluffier texture. Yes, you should be able to to find dolce de leche at Kroger – usually in ethnic food area or baking.
