Sometimes I could truly kick myself for having a recipe saved for so long before finally trying it.  This one had been sitting waiting patiently for a year and a half.  At least for me, it’s easy for banana caramel to be overlooked in favor of something uber chocolatey or maybe something involving cheesecake – but I will not make that mistake again.  These cupcakes are truly divine.  The banana flavor in the cake and the caramel in the frosting are both prominent and compliment each other perfectly.  I am normally not one to play around with baking recipes for fear of a batter that will never solidify or be far too dry, but I did make some alterations to this and they ended up working out really well.  As an added bonus, any recipe that leaves me with a leftover squeeze-bottle full of homemade caramel sauce – well, that’s a winner.

I’m not going to lie – the frosting takes a looong time to make.  It took quite a while for the egg-sugar mixture to reach the desired temperature.  (Next time I’ll be absolutely sure my eggs are at room temperature – I may have skipped that step.)  Not only that, but as you add the butter, it seems like it is never going to come together and you think you just wasted all that time.  But then, you add the last couple pieces and some magical state is reached that transforms it into a nice, thick buttercream.  Finally you mix in the caramel and the texture becomes silky smooth and the flavor the caramel contributes takes this to a whole new level.  It may have been an ordeal to make, but I think it was completely worth the effort.  This may be my new favorite frosting.  Stay tuned next week to see what I did with my leftover caramel (it’s gooood!)

  • Yield about 30 cupcakes

Ingredients

For the cupcakes:
2½ cups all-purpose flour
1 tbsp. baking powder
½ tsp. salt
12 tbsp. unsalted butter, at room temperature
2½ cups sugar
6 eggs
1 cup plus 2 tbsp. buttermilk
1 1/3 cups mashed ripe banana

For the caramel:
8 tbsp. unsalted butter
½ cup heavy cream
1 cup packed light brown sugar

For the frosting:
3 large egg whites, at room temperature
¾ cup sugar
Pinch of salt
16 tbsp. unsalted butter, cut into 1 tbsp. pieces, at room temperature

Directions

  • 01

    To make the cupcakes, preheat the oven to 350° F.  Line two cupcake pans with paper liners.  In a medium bowl combine the flour, baking powder and salt; whisk together and set aside.  In the bowl of a stand mixer fitted with the paddle attachment cream together the butter and sugar on medium-high speed until light and fluffy, about 2 minutes.  Reduce the mixer speed to medium low and add in eggs one at a time, scraping down the sides of the bowl as needed.  Mix in the mashed banana until well combined.  With the mixer on low speed alternately add the dry ingredients and buttermilk, beginning and ending with the dry ingredients and mixing only until just incorporated.

  • 02

    Divide the batter between the prepared cupcake liners, filling each about 2/3 to ¾ full.  Bake until a toothpick inserted in the center comes out clean, about 20-22 minutes.  Allow to cool in the pan 5-10 minutes, then transfer the cupcakes to a wire rack to cool completely.

  • 03

    To make the caramel sauce, combine the butter, heavy cream and brown sugar in a medium heavy-bottomed saucepan over medium-high heat.  Bring the mixture to a boil, stirring constantly.  Once it reaches a boil, lower the heat to medium and continue to boil until the mixture is thickened, about 8 minutes.  Remove from heat and let cool.

  • 04

    To make the frosting, combine the egg whites and sugar in a large heatproof bowl set over a pot of simmering water.  Heat the mixture, whisking very frequently, until the sugar is completely dissolved and reaches 160° F on an instant read thermometer.  Transfer the mixture to the clean, dry bowl of a stand mixer fitted with the whisk attachment.  Beat on medium-high speed until the mixture holds stiff peaks.  Reduce the speed to medium low, add in the salt and begin adding the butter one piece at a time, beating well after each addition.  Stir in ½ cup of the cooled caramel sauce until well blended.

  • 05

    Frost the cooled cupcakes with the caramel buttercream, and drizzle with the remaining caramel sauce.  (If the caramel has cooled too much to be easily drizzled, heat for 10 seconds in the microwave and stir well to thin it a bit.)
