Preheat the oven to 350°F (176°C) and generously spray a
9x13-inch baking pan with cooking spray.
In a large bowl, combine flour, baking powder, and salt.
In a mixing bowl, beat egg yolks with 3/4 cup sugar on high
until yolks are pale yellow.
Stir in regular milk and vanilla, and add the mashed bananas.
Pour egg yolk mixture over the flour mixture and stir gently
until combined.
Beat egg whites on high speed until soft peaks form. With the
mixer on, pour in remaining 1/4 cup of sugar and beat until egg
whites are stiff but not dry.
Fold egg white mixture into the batter carefully until combined.
Pour a third of the cake batter into a separate bowl and mix 1
teaspoon on ube extract.
Pour into the prepared baking pan alternating between plain
banana batter and ube banana batter.
Bake for 30-40 minutes or until a toothpick comes out clean.
Turn cake out onto a rimmed platter and allow to cool.
After cooling, prick the top of the cake with a fork. In a large
measuring cup, combine condensed milk, evaporated milk, and 1/4
cup heavy cream. Mix thoroughly.
Drizzle all but 1 cup of milk mixture. Allow the cake to absorb
milk for at least 30 minutes.
Drizzle the remaining cup of milk mixture over the top of the
cake.
Whip the remaining 1 3/4 cups heavy cream with 1 tablespoon of
sugar until thick and spreadable. Spread the whipped cream over
the surface and sides of the cake.
Garnish with toasted nuts or peanut crumble & banana slices.
