  • CAKE
  • 3 cups all purpose flour
  • 2 cups granulated sugar
  • 1 tsp baking soda
  • 2 tsp cinnamon
  • 1 tsp salt
  • 3 large eggs room temp
  • 1 cup canola oil
  • 1 tsp vanilla extract
  • 2 cups mashed ripe banana
  • 1/2 cup milk room temp
  • 5 egg whites
  • 1 1/4 cup granulated sugar
  • 2 cups unsalted butter room temp
  • 2 tsp vanilla extract
  • 1 tsp salt
  • 1 can dulce de leche (can be found by the sweetened condensed milk)
  • 3 bananas sliced
  • additional banana slices
  • dulce de leche for drizzling
  • chopped up Heath candy bar


  • CAKE:
  • Preheat oven to 350 degrees F.
    Grease, flour and parchment 4 - 7" cake pans.
    In bowl of mixer add in all the dry ingredients.
    Add in the eggs, oil and vanilla, mix until just combined.
    Add in the bananas and stream in the milk.
    Mix until just combined and batter is formed.
    Pour into prepared cake pans.
    Bake for 25-30 minutes or until toothpick inserted comes out clean.
    Let cool completely.
  • In large sauce pan add the egg whites and sugar.
    On medium heat you are going to whisk egg mixture until sugar is completely dissolved (you can test it by rubbing a small amount between your fingers to test it, it should be completely smooth).
    Let mixture cool to room temp. (if not completely cooled your butter will melt)
    Transfer to mixing bowl and with whisk attachment whisk on high until stiff peaks form.
    Switch to paddle attachment.
    Add in the salt.
    On low speed add the butter one piece at a time and the vanilla.
    Mix until well combined, smooth and creamy.
  • 1. Cut off the round tops of cakes if need be.
    2. Lay first cake layer on cake plate/board (add a bit of frosting underneath to hold the cake in place).
    3. Spread a thin layer of buttercream over the cake layer making sure to go to the edges and then pipe a band of buttercream around the edge. This will keep the dulce de leche in place once added.
    4. Scoop and spread dulce de leche over the thin layer of buttercream.
    5. Arrange sliced bananas on top of the dulce de leche.
    6. Stack the next cake layer on top of the first.
    7. Repeat steps 3 thru 6 with the remaining 3 layers.
    8. Stack slice bananas on top of the cake. Sprinkle outer top edge with chopped Heath candy bar. Drizzle with dulce de leche.
    9. Optional: You can swipe extra dulce de leche around the buttercream as shown in the pictures. I used a small offset spatula and wiped it around each buttercream layer.
    You can refrigerate cake but take out at least an hour before serving as its best served room temp.
