Directions
- Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper.
- Cream together 1/2 cup of unsalted butter, 1/2 cup of brown sugar, and 1/2 cup of granulated sugar until light and fluffy.
- Add 1 egg, 1 teaspoon of vanilla extract, and 1 cup of mashed bananas. Stir until combined.
- In a separate bowl, whisk together 1 ½ cups of all-purpose flour, 1 teaspoon of cinnamon, 1 teaspoon of baking soda, and 1/4 teaspoon of salt. Gradually add 1/4 cup of cornstarch.
- Slowly incorporate the dry ingredients into the wet mixture. Fold in 2 cups of old-fashioned oats until evenly distributed.
- Drop rounded balls of dough onto the prepared baking sheets, spacing them about 2 inches apart. Flatten each gently.
- Bake for 10-12 minutes until the edges are golden brown and the centers remain soft.
- Let the cookies cool on the sheets for 4 minutes before transferring to wire racks.
- Mix 1 cup of marshmallow crème with 1/2 cup of creamy peanut butter, 1/4 cup of shortening, and 1 cup of powdered sugar, adjusting with hot water for desired consistency.
- Spread filling on the flat side of one cookie and top with another. Press gently to form a sandwich.

Notes
Use overripe bananas for best results and allow cookies to cool completely before adding filling.
