Step 1

Place a rack in the center of your oven and preheat the oven to 350 degrees F. Line an 8x8 inch baking pan with parchment paper so that the parchment overhangs two opposite sides like handles. Lightly coat with nonstick spray and set aside.

Step 2

Mash the bananas in a mixing bowl. Double check the measurement to ensure you have 1 cup (less will make the bars dry; more and they may not bake all the way through). Stir in the coconut sugar, butter, milk, egg, and vanilla until well blended.

Step 3

In a separate bowl, stir together the flour, baking soda, cinnamon, nutmeg, and salt. Add the dry ingredients to the bowl with the wet ingredients. With a wooden spoon or spatula, stir to combine, stopping as soon as the flour disappears. Fold in 1/3 cup chocolate chips.

Step 4

Scrape the batter into the prepared baking pan and smooth the top. Sprinkle the remaining 2 tablespoons chocolate chips on top. Bake for 16 to 20 minutes, or until a toothpick inserted in the center comes out clean with just a few moist crumbs clinging to it. Place the pan a wire rack to cool completely, then using the parchment handles, lift the bars onto a cutting board. Slice into squares of desired size and enjoy!
