Step 1

Add the mashed bananas to a medium bowl. Add the rest of the ingredients, including the chocolate chips if using. Stir to combine thoroughly with a spoon.

Step 2

Place batter in the fridge or freezer while the oven preheats to 375 degrees F. (Chilling the batter helps it hold together for scooping and portioning.)

Step 3

Line a baking sheet with parchment paper. Scoop and drop 1-tablespoon-size balls of the batter onto the prepared baking sheet. Press slightly to flatten to about 1/2-inch thick.

Step 4

Bake for 12-14 minutes, or until cookies are lightly golden brown around the edges and firm to the touch.

Step 5

Remove from oven and let cool on the baking sheet.

Step 6

If you want to add icing, you can drizzle cookies with vanilla yogurt. Place yogurt into a zip-top bag with a small corner cut off and pipe over the cookies.

Step 7

Serve immediately or store.
