• To Prep: Preheat oven to 375°F and grease a 9x13-inch baking pan.

Cake Instructions

• In a medium bowl, whisk together the flour, baking soda, and salt.
• In a separate large mixing bowl, cream together the granulated sugar and softened butter with an electric mixer until light and fluffy. Mix in the eggs.
  
• Beat in the sour cream, mashed bananas, and vanilla extract.
• Pour the dry ingredients into the bowl of wet ingredients, mixing until just combined.
• Pour batter into the prepared pan. Spread with a spatula if needed. Bake for 25-30 minutes until a toothpick inserted into the center comes out clean, then remove the cake from the oven and cool to room temperature.

Frosting Directions

• Place the butter in a large skillet over medium heat and cook until the butter melts and begins to turn a light golden brown.
• Remove pan from heat and whisk in the powdered sugar and vanilla. The frosting will still be thick and chunky at this point.
  
• Add 2 Tablespoons of heavy whipping cream and whisk until the frosting is smooth. If needed, add a little more cream until you have a smooth consistency.
• Spread the frosting evenly on top of the cooled cake.
