Step 1

Preheat the oven to 325 degrees Fahrenheit with two racks near the middle. Line two baking sheets with parchment paper (if you don’t have parchment paper, lightly grease the baking sheets).

Step 2

Measure out the honey and peanut butter—I found this easiest to do in a small liquid measuring cup. Add honey to the ½ cup line, then add peanut butter until you reach the 1 cup total liquid line.

Step 3

Pour the honey and peanut butter mixture into a mixing bowl. Add the mashed banana and melted butter and whisk until the mixture is well blended. Use your whisk to beat in the egg, scraping down the side of the bowl once it’s incorporated. Whisk in the vanilla, baking soda, baking powder, salt and cinnamon.

Step 4

Switch to a big spoon and stir in the ground oats, rolled oats, chocolate chips and sprinkles until they are evenly combined. Drop the dough by the heaping tablespoon (a small cookie scoop is perfect for this) onto your prepared baking sheets. I added a few extra sprinkles on top for good measure.

Step 5

Bake the cookies, reversing the pans midway through (swap the cookies on the top rack with the cookies on the lower rack) until they’re barely set and just beginning to turn golden around the edges, about 16 minutes. Remove the cookies from the oven and let them cool completely on the pans. If desired, sprinkle lightly with flaky sea salt now.
