For the Banana Cake

  • 1/3 cup unsalted butter room temperature
  • 1 1/2 cups granulated sugar
  • 3 large eggs room temperature
  • 2 3/4 cup all purpose flour sifted
  • 1 1/2 tsp baking powder

For the Whipped Cream

Instructions

For the Homemade Banana Pudding

  • Add the milk and cream to a medium saucepan over medium heat. Bring to a simmer, stirring often.
  • In a medium bowl, whisk together the eggs, sugar, and cornstarch until well blended.
  • Spoon a little of the hot milk over the egg mixture and whisk well. Repeat with another few spoonfuls of the hot milk, to temper the eggs (bring their temperature up without “scrambling” them).
  • Pour the egg mixture into the saucepan and continue to cook over medium low heat for 4-6 minutes, or until it thickens and coats the back of a spoon. If you’re still unsure, use a thermometer: it should read 170-175F.
  • Once thickened, remove from the heat and stir in the butter, vanilla extract, banana extract, and salt.
  • Pour the pudding through a sieve or fine mesh strainer into a container, to remove any lumps.
  • Place a piece of plastic wrap or wax paper directly on top to prevent a skin from forming. Refrigerate for at least 2 hours, or until completely chilled and set. Stir well before using.

For the Banana Cake

  • Preheat the oven to 325°F. Liberally spray 3 (8-inch) round cake pans with non-stick baking spray or grease and flour.
  • In your mixer bowl, add oil and butter and beat for 2 minutes on high speed. Slowly add in sugar and beat on high speed for an additional 4-5 minutes until very pale yellow and fluffy. Next, add eggs, one at a time, combining well after each addition and scraping down the sides as needed.
  • Turn your mixer down to its lowest speed, and slowly add flour into batter in two increments then add baking powder, salt and baking soda. Be careful not to over beat.
  • Lastly, add sour cream, milk, vanilla extract and banana extract, then scrape down sides and mix until just combined and turn off the mixer.
  • Evenly pour cake batter into prepared baking pans and place in the oven to bake for 15-25 minutes or until a toothpick inserted into the center of the cake comes just barely clean.
  • Remove cakes from the oven and rest in pans for 10-15 minutes. Invert cakes from pans onto cooling racks, then allow them to cool to room temperature.

For the Whipped Cream

  • Whip cream, sugar, and vanilla until stiff peaks (in a cold bowl with a cold whisk for best results).
  • Chill until ready to use.

To Assemble

  • Place one layer of cake on a cake stand or serving plate. Spoon ½ of the banana pudding onto the cake and use a spatula to spread it to the edge, leaving about a ¼ inch of space.
  • Starting from the outer edge, and moving in a circle, alternate between placing a Nilla wafer or banana slice on top of the pudding.
  • Place the next layer of cake on top, then repeat the previous step.
  • Add the last layer of cake on top, then proceed to frosting the cake with the premade whipped cream.
  • Do rosettes on top with the whipped cream and alternate banana slices and Nilla wafers between them. Spread some crushed Nilla wafers along the bottom if desired.

Notes

STORING THE LEFTOVERS
Because of the perishable filling, you’ll want to refrigerate this cake for a couple hours before serving. This time will allow all the flavors to come together and the filling/ frosting to firm up a bit. Allow Banana Pudding Layer Cake to soften at room temperature for about 15-30 minutes before serving.
Any leftover cake should be stored in an airtight cake keeper or sliced and tucked into individual containers. Refrigerate for 2-3 days. I would not recommend freezing this cake.
