Step 1

Adjust the oven rack to the second level position (just above center) and preheat the oven to 350ºF.

Step 2

Generously spray an 8 inch square cake pan with a flour-based baking spray. Set aside.

Step 3

In a medium bowl, whisk together the all-purpose flour, baking soda, baking powder, and salt. Set aside.

Step 4

Using a hand mixer or a stand mixer fitted with a paddle attachment, beat the unsalted butter and mushed bananas together on medium-high speed until well-combined. Add in the light brown sugar, granulated sugar, vanilla extract, and egg, mixing together until fully incorporated.

Step 5

Switch the mixer speed to low and add in the whisked dry ingredients until just combined. The batter will be thinner in consistency with flecks of the bananas in it.

Step 6

Before adding the chocolate chips, coat them lightly 1 tablespoon of all-purpose flour which will help them from all sinking to the bottom of the pan during the baking process.

Step 7

With a spatula fold in the flour coated chocolate chips, then pour the cake batter into the prepared 8 inch cake pan.

Step 8

Bake for 25-30 minutes at 350ºF or until an inserted toothpick into the center of the snack cake comes out clean.

Step 9

Allow the cake to cool completely before frosting.

Step 10

Using a hand mixer or a stand mixer fitted with a paddle attachment, beat the unsalted butter and cream cheese together on medium-high speed for 2-3 minutes until the mixture is smooth and creamy. There should be no lumps.

Step 11

Add in the unsweetened cocoa powder, powdered sugar, vanilla extract, and heavy cream, beating together on low speed until well blended. The frosting will be thick at first.

Step 12

Once mixed together, switch the mixer speed to medium-high blending together until the frosting softens (about 2-3 minutes). It will be much easier to spread after this.

Step 13

If the frosting is still too thick for your liking, you can add a teaspoon of heavy cream until the desired consistency is achieved.

Step 14

Frost the cooled snack cake and enjoy!
