Course Dessert, Snack

Ingredients
  

Cookies

  • very ripe bananas Spots = sweeter and better binding.
  • certified gluten-free oats Be sure they’re labeled GF if you’re celiac.
  • ground cinnamon
  • vanilla extract
  • fine salt Optional.
  • optional mix-ins Chocolate chips, walnuts, raisins, coconut flakes — about 1/2 cup total.

Instructions
 

  • Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper. These cookies love to stick, so parchment helps.
  • Mash the very ripe bananas in a mixing bowl until mostly smooth. A smoother mash gives more even baking.
  • Stir in the oats, cinnamon, vanilla, and salt (if using) until the mixture is thick and sticky.
  • Fold in your mix-ins, aiming for about 1/2 cup total so the cookies stay balanced and hold together.
  • Scoop tablespoon-sized mounds of dough onto the prepared baking sheet and flatten each slightly, as the cookies won’t spread much while baking.
  • Bake for 12–15 minutes, or until the edges are lightly golden. The cookies will firm up as they cool.
  • Cool the cookies on the tray for about 5 minutes, then transfer to a cooling rack. Enjoy soft and warm, or let them cool completely for a chewier texture.

Notes

Very Ripe Bananas: Spots = sweeter and better binding.
Certified GF Oats: Be sure they’re labeled GF if you’re celiac.
Optional Mix-Ins: Chocolate chips, walnuts, raisins, coconut flakes — your call.
Reader tip: Add a spoon of cocoa powder and call them “brownie bites.”
Storage & Budget Tips: Store airtight on the counter up to 3 days; refrigerate up to a week; freeze in snack bags. Skip chocolate chips to save money — raisins or plain are great. Add 1–2 tablespoons peanut butter for extra protein.
Why This One’s Beginner-Friendly: No flour, no mixer, no special tools. Likely ingredients you already have. Almost impossible to mess up.
