Banana Cake with Salted Caramel Frosting

Salted Caramel Sauce is a Must

Salted caramel has long been one of my favorite treat of mine and what makes it so special really is the salt.

Last December I had the opportunity to attend Morton Salt’s Next Door Chef event in New Orleans along with several other guests. It was such a fun dinner experience where they converted someones home into an actual pop-up restaurant for a day.

Acclaimed chef Nina Compton coached a home cook and then this cook prepared an incredible meal for us in which different types of Morton salt were used.

At the event we tried a number of inspiring dishes where we could taste how different types of salt transformed each dish, from appetizer and drinks, to side dish, to the main dish and then onto dessert.

Of course, my favorite part of the meal was the Coconut Caramel Budino with Grilled Mangos and Morton Kosher Salt which was served for dessert. I just love the way the salt really highlighted that dessert and it does just the same here!

The dinner was so inspiring! I couldn’t say a negative thing about anything I tried. And part of the reason it was all so good was that it was properly seasoned with salt.

Salt makes a world of difference in everything we cook and bake. It can drastically change the end result. Can you imagine a world of food without salt??

Ready in: 1 hour 10 minutes

Ingredients

  • Banana Cake recipe see notes

Caramel sauce

  • 1 cup (210g) granulated sugar
  • 1/4 cup water
  • 3/4 tsp Morton Fine Sea Salt
  • 1/4 cup (56g) unsalted butter, diced into 1 Tbsp pieces
  • 2/3 cup (160ml) heavy cream
  • 2 pinches Morton Coarse Sea Salt, for topping

Frosting

  • 3/4 cup (170g) unsalted butter
  • 3 cups (390g) (360g) powdered sugar
  • 1 tsp vanilla extract
  • 1/2 cup caramel sauce (from above)
  • 1/2 cup chopped pecans or walnuts, for garnish (optional)
  • 2 bananas, diced, for topping (optional)
  • Semi-sweet chocolate shavings, for garnish (optional)

Instructions

  • Prepare banana cake as directed and let cool completely. Meanwhile prepare the caramel sauce.
  • For the caramel sauce: have all caramel ingredients ready. In a medium saucepan combine sugar, water and sea salt. 
  • Set over medium-high heat and whisk constantly until it begins to boil, then allow mixture to boil until it turns to a rich amber color, carefully swirling pan occasionally. 
  • Immediately whisk in butter then remove from heat and whisk in cream (be careful, it will steam! A long handled whisk is recommend) and stir until smooth. 
  • Allow to cool several minutes then pour into a glass bowl or jar and chill caramel until completely cooled.
  • For the frosting: whip butter until light and fluffy. Add powdered sugar, 1/2 cup of the cooled caramel sauce, sea salt and vanilla.
  • Mix until well combined and slightly fluffy. Chill until it becomes a more firm consistency if needed.
  • To assemble cake: spread about half of the frosting over first layer of cake then drizzle and spread a fair spoonful of the caramel sauce over the frosting. 
  • Top with the second layer of cake then add remaining frosting. Just before serving top with the bananas* and nuts, then drizzle over remaining caramel sauce, sprinkle with shaved chocolate and coarse sea salt.

Notes

  • Follow link HERE for the recipe for the banana cake. Only make the cake portion.
  • *To slow browning of the bananas if needed, you can soak them in a lemon water solution for about 1 minute. Just add 1 Tbsp lemon juice to about 1 cup of water then dry slightly on paper towels.

Incredible chef Nina Compton and myself.

    Hey Jaclyn,

    This cake looks so good! Im hoping to make it for a church gathering this weekend. My question is about how thick should these layers be? Just the cake itself. I’ve just started practicing with cakes the last 6 or 8 months, and I can’t seem to get a thick cake layer to save my life. They usually taste ok but the layers only end up being about an inch thick. Any tips? I actually went ahead and made the cake today. They are about an inch like usual. Have a wonderful weekend. Thanks so much for your time!☺️

      Are you at a high altitude? Mine generally don’t come out very high either because I’m at about 4200 ft but there are a few things you can do to help (if it’s an altitude issue) – you may find something here https://www.kingarthurflour.com/learn/high-altitude-baking.html. Otherwise it could be a few other things like the butter not being whipped up enough as this incorporates air bubbles or the batter being over-mixed, you just want things to be incorporated. You can also try beating the egg whites and folding those into the batter at the end.
      And note, for measuring the flour I used the scoop and sweep method vs. spoon and sweep – having the right amount of flour will help!

    This cake looks absolutely divine, Jaclyn!

    I was going to a family reunion this past weekend and didn’t think a layer cake would travel well. I used your To Die For banana cake (9×13) and then used this frosting, salted caramel sauce, sliced bananas and chopped pecans on top. Everyone loved it and I was asked to bring it back next year!

    The link to the cake recipe is not active. Would you post it?

    Is it my browser acting up or is there no link to the banana cake recipe? Trying to access it but can’t seem to find a link to it anywhere…

  • Mindy

    I made this for a family reunion this weekend and was asked to bring it again next year!
    Since I was traveling I made it in a 9×13 pan instead of layers. So delicious.

  • Abbey

    I made this cake, it is so delicious and was a big hit with my coworkers! Thanks so much for sharing.
