Step 1

Preheat oven to 350 degrees F.

Step 2

In a large bowl mash the bananas. Add the vegetable oil and egg and mix to combine.

Step 3

Add 1 cup of graham cracker crumbs and the cake mix and mix thoroughly. The dough will be very thick.

Step 4

Using a medium cookie scoop (about 1.5 tablespoons), scoop the batter and place each scoop about 2 inches apart on a cookie sheet.

Step 5

Sprinkle the tops of the cookies with the remaining graham crumbs.

Step 6

Bake for 8-12 minutes, until the bottoms are golden and the tops are starting to brown. Cool for 10 minutes before removing from the baking sheet.
