This chocolate banana trifle will become the highlight of any party of special occasion you make it for thanks to Perugina dark and bittersweet chocolate.
Preheat oven to 350º and place rack in center of oven. Spray a 9-inch cake pan with cooking spray and line the bottom with parchment paper.
Into a large bowl, sift the flour, cocoa powder, baking powder, baking soda, and salt.
In another large bowl, whisk together the eggs, sugar, coffee, milk, oil, and vanilla.
Add the wet ingredients to the dry and whisk until well combined (the batter will be thin). Pour the batter into the prepared pan and bake for about 30-35 minutes, until the center bounces back to the touch or a toothpick inserted into the center comes out clean.
Remove from oven and let cool on a wire rack for about 10 minutes. Then invert the cake from the pan and allow to cool completely. Cut the cake into 1 1/2" pieces and set aside until ready to assemble.
Pour the heavy cream into a large mixing bowl with the confectioner’s sugar and vanilla, and beat with a hand mixer on medium-high speed until the cream reaches stiff peaks.
Stir together the mascarpone and bananas in a medium bowl until well combined.
Gently fold the mascarpone and banana mixture into the whipped cream until evenly incorporated. Do not overbeat. Set aside until ready to assemble.
Place the chocolate in a non-reactive bowl over gently simmering water. Heat, stirring constantly with a wooden spoon, until the chocolate has melted. Turn off the heat and leave the bowl over the water until ready to use.
Place the heavy cream in a large bowl in an ice bath and, beat with an electric mixer on medium-high speed until soft peaks form. Set aside in the ice bath.
Place the egg whites in a very clean medium bowl and, with an electric mixer on medium-high speed, beat until soft peaks form. Gradually add the sugar and continue beating until the whites reach firm, but not stiff peaks.
With a rubber spatula, fold the melted chocolate into the egg whites, scraping up from the bottom of the bowl to blend completely. When all of the whites have been fully incorporated with the chocolate, fold in the reserved whipped cream. When well blended, cover with plastic wrap and set aside until ready to assemble.
