A moist and tender cake infused with the sweet goodness of ripe bananas, studded with bursts of gooey chocolate chips. Enjoy as a casual dessert or an afternoon snack.
Pre-heat the oven to 350°F then coat the bottom of an 8x8 square baking pan with non-stick cooking spray. Line the bottom with parchment paper; set aside.
In the bowl of a stand mixer, or using an electric mixer, beat the brown sugar, butter, and oil together until fluffy; about 3 minutes. Scrape down the sides of the bowl, then add the eggs and vanilla, one at a time, beating between each addition.
Add the flour, baking powder, baking soda, cinnamon, cardamom, and salt to the bowl. Mix together gently just until incorporated. Alternate adding the mashed bananas and milk while mixing between each addition. Stir in the chocolate chips being sure not to overmix your batter.
Pour batter into prepared baking pan. Bake at 350° F for 30-40 minutes or until a toothpick inserted into the center comes out mostly clean. Let cool to room temperature before inverting onto a wire rack and removing parchment to cool completely.
