Banana Nut Breakfast Bars

Preparation

1. Step 1

   In a large bowl, use a fork to mash the bananas; you should get about 1 cup mashed bananas. Add the eggs and whisk with the fork to evenly combine. Set the mixture aside for 15 minutes.

2. Step 2

   Adjust oven rack to lower-middle position and heat to 350 degrees. Grease an 8- or 9-inch square pan and line it with a long sheet of parchment paper to cover the bottom and two sides, creasing as needed to ensure a secure fit.

3. Step 3

   Add the olive oil, peanut butter, honey, kosher salt, cinnamon and vanilla to the banana mixture and whisk until smooth. Add the oats and whisk to combine.

4. Step 4

   Scrape the mixture into the prepared pan, then top it with the walnuts and a light sprinkling of flaky salt. Bake until the top feels set when pressed lightly and a toothpick inserted into the center comes out clean, 35 to 40 minutes.

5. Step 5

   Cool fully before using the parchment to lift the bars out of the pan. Cut into 9 squares and store in an airtight container at room temperature for up to 5 days.
