How to Make Banana Chocolate Chip Birthday Sheet Cake

1. Preheat oven to 350°F (175°C).
2. Grease and flour a 13x9 inch baking pan.
3. In a medium bowl, mash 3 ripe bananas with 1/2 cup sour cream until completely smooth.
4. Beat in 2 large eggs, 1 teaspoon orange zest, and 1 teaspoon vanilla extract until well combined.
5. In a large bowl, whisk together 2 1/2 cups all-purpose flour, 1 3/4 cups granulated sugar, 5 teaspoons baking powder, 1 teaspoon baking soda, and 1/2 teaspoon salt.
6. Cut in 1 cup (2 sticks) softened unsalted butter using a pastry blender or your fingers until the mixture resembles coarse crumbs.
7. Add half of the banana mixture to the dry ingredients and beat on low speed until just combined.
8. Stir in the remaining banana mixture and 1 1/2 cups chocolate chips using a wooden spoon or spatula until just combined. Do not overmix.
9. Pour batter into the prepared pan and spread evenly.
10. Bake for 40-45 minutes, or until a wooden skewer inserted into the center comes out clean.
11. Let the cake cool in the pan for 15 minutes before running a knife around the edges.
12. Invert the cake onto a wire rack to cool completely.
13. While the cake cools, prepare the icing (recipe below).
14. Once the cake is completely cool, frost with the prepared icing.
